KCS Pro Kayak Sail System test and review.


Photo by Donald Wilcox

Since lock down lifted I have been testing various prototypes of the KCS KY-PRO Sail System. The system is available in three versions:

1. Sail only to fit other rigs such as Flat Earth Kayak Sails.

2. Sail, carbon fibre mast and boom, universal joint and deck fittings which require the deck to be drilled.

3. Sail, carbon fibre mast and boom, custom front hatch with mast foot and stay fittings, cleats that can be attached to the RDF fittings near the cockpit by using longer bolts. This option is for those that do not want to drill their deck or want to attach a sail to a borrowed, hired or demo boat.

Background to the test
I have been a long time user of a variety of kayak sailing systems. I have owned and used Pacific Action V sail, the KayakSailor rig and various Flat Earth kayak sails. I have also borrowed and used the Baloghsailsystems Batwing and Falcon Sails rig. They all are excellent in their own way and each has their strengths and weaknesses.


For the type of paddle sailing I do in the west of Scotland I prefer the Flat Earth sails in 0.8sqm size. They suit the open exposed waters and the sometimes gusty winds off the mountains. They are not as large and powerful as the KayakSailor, Baloghsailsystems and Falcon Kayak Sails rigs so you always need to paddle while you sail but in chilly Scotland this keeps you warm, especially in winter. The Flat Earth Kayak Sails in addition to being smaller also have a looser leach and this gives them a much wider wind range than the other designs.

I was therefore delighted when Ronnie Weir of KCS produced his prototype sails to find they are a similar size to Flat Earth designs and, though of different design and materials, have a similar range of intended use, i.e. for most users they are intended to be used on flat or rough open water from F2 up to F4/5. The KCS sails are made in Scotland by Owen Sails, a long established yacht sail maker based in Oban. Owen Sails started out in the mid 1980s making windsurfing sails and I still have one of their 6sqm, six batten slalom sails. So they know about smaller sails too.

This test was carried out on the Solway Firth, Firth of Clyde, Firth of Lorn, Sound of Sleat, Loch Hourn, Kyle Rhea, Inner Sound and Loch Carron on the west coast of Scotland. Conditions varied from F2 to F5.

Sail construction.

This sail is constructed from heavier cloth than the equivalent Flat Earth sails. The 0.75sqm KCS is also a good bit smaller than the FE 0.8sqm. The upper/luff panel is made of Dacron which is flexible enough to give warning when the sail is about to backwind if you point too high into the wind. The leech/lower panel is made of a heavier trilaminate cloth than that used in Flat Earth. The sail is loose footed unlike the Flat Earth TradeWind sail, where the boom is sewn into the sail like a batten. The KCS also has a longer boom and sets fuller with a deeper draught than the equivalent size FE. Like the FE TradeWind sail, the KCS sail is a spritsail with a single diagonal batten, which rises from the tack (the corner of the sail where the boom meets the mast). The KCS sail has a stiffer batten than the FE and the batten is sewn into the pocket with more tension than in the FE. This means it puts more 3D shape into the sail making it more powerful for its size. However, in very light winds, the batten might flip its curve to the wrong side of the sail. The stiffer batten also holds onto the sail's power longer in a gust before twisting off and releasing wind pressure from the roach of the sail (the part near the upper end of the batten).



The 0.75sqm KCS KY-PRO sail overlaid on a 0.8sqm Flat Earth TradeWind sail. Note similar head and upper roach but reduced area, shorter luff and longer foot of the KCS. 

1. The KCS KY-PRO 0.75sqm sail tested  Flat Earth aluminium mast and boom with the mast foot bolted to the foredeck forward of the compass recess.

The KCS sail was paddled alongside a Flat Earth TradeWind 1.0sqm and...

...a Flat Earth TradeWind 0.8sqm in a variety of wind strengths from F2 to F5.  The KCS sail performed excellently overall but especially in the higher winds. In lighter winds both sizes of the FE TradeWind sail have the edge on a reach/broad reach.






However, at bottom of  F4 the KCS produces more power and in  mid F4 and above feels significantly more powerful than the 0.8sqm TradeWind. In gusty F4 conditions the TradeWind remains very controllable due to the leech twisting off more easily but in doing so it looses power. The tighter leeched KCS is more powerful but, as it is significantly smaller, remains a lot of fun in these conditions. It does require a bit more experience to handle than the TradeWind in these upper end conditions. In this respect, it is similar to the double battened, loose footed, Flat Earth Footloose sail. Overall, I think the KCS sail is a good compromise between size, leech tension and fullness of cut/power for use on exposed open water. Upwind when paddling in F3/F4 there is little performance difference between the KCS and the Tradewind except, when well worn, the loose Tradewind leech motors (flaps) in the breeze.  The KCS sail is not showing signs of this after two years of use.

2. The KCS KY-PRO 0.75sqm sail tested on the KCS carbon fibre mast and boom with the mast foot bolted to the foredeck, forward of the compass recess.
The KCS carbon fibre mast is one piece but a two piece may be available in the future. 

The compression collar round the mast retains the two back stays, two side stays and the uphaul/fore stay. It is simple and avoids the need to drill the mast, which could weaken it. A longer thinner collar at the bottom of the mast slides over the mast base universal joint stub.

The most recent P&H composite kayaks like the Volans have a moulded flat forward of the compass to 
mount the deck plate. They also have deckline RDFs mounted laterally to the deck plate position to give the best support to the past. The side and back stays can be attached to these using a short loop of the supplied 2mm dyneema line.

Older P&H composite kayaks like the Cetus usually do not have a suitable deckline RDF lateral to the deck plate. The fitting kit comes with two SDF fittings that can be bolted through the seam wich is very strong compared with the decks in some kayaks.

The fore deck of all P&H composite kayaks has been reinforced for a mast foot for about the last 10 years. On other kayaks such as this Evolution Kayaks Nomad (Northshore Atlantic) and my Nordkapp LV I have reinforced the underside of the deck (from seam to seam) with  a 10cm wide arch  of 10oz woven cloth and resin.

KCS mast foot on left Flat Earth mast foot on the right.

The KCS UJ/mast foot is a Seasure Quick Release Tiller Extension Joint. The deck plate fixing hole centres of this and the current black Ronstan fitting used by Flat Earth sails are both 22mm apart. The original Flat Earth red deck plate (photo above) had hole centres 32mm apart. If you already have a red Flat Earth deck plate on your kayak, you can use the FE UJ/mast foot with the KCS mast. However, the KCS mast foot is 18mm in diameter and the Flat Earth mast foot is 16mm in diameter. You can do as I have done and pad out the Flat Earth mast foot with electrical tape or KCS can supply a carbon fibre sleeve to glue over the Flat Earth mast stub.

If you have no previous sail fitting then you will need to drill the kayak deck. P&H RM kayaks come with brass inserts with centres 32mm apart for the red FE deck plate. However, for both current KCS and Flat Earth deck plates you will only be able to use one insert and so will need need to drill one hole.

The boom has a very neat hinged joint at the gooseneck and...

...the sheet is attached to the boom with an elastic loop to help absorb the force of gusts.

...the outhaul is very slim and neat and allows more expert paddle sailors to control the fullness of the sail.

There is no kicking strap on this type of sail and as the shrouds are below the boom, the boom can swivel forward  in front of the mast. This is an important safety feature as it allows you to depower very quickly if you get hit from behind by a sudden overpowering squall. In these conditions it can be very difficult to either pull the sail down towards you against the wind or to turn the bow into the wind to allow the sail to be blown back towards you.

Everything worked well, the sail set nicely on the carbon fibre spars.  These look great, but I could not honestly detect any difference in performance over the aluminium spars in the Flat Earth rig.

The sheet (yellow) comes down from the boom and threads through a Ronstan shock block that is attached to the forward midline deck elastic RDF by 2mm dyneema. 

The sheet then runs back to an open Fineline cleat in front of the cockpit which has been fitted by drilling through the deck. For those paddle sailors who cannot bear to drill holes in a shiny sea kayak see next section. The forestay/uphaul goes from the mast forward to another Ronstan shock block which is attached to the forward deckline RDF at the bow and then back to another fineline cleat on the other side of the cockpit.

3. KCS KY-PRO Sail, carbon fibre mast and boom, tested on custom front hatch with mast foot and stay fittings.

This is a really novel and well engineered solution for people who do not like drilling holes in their kayak. It consists of a circular outer plate just bigger than the hatch rim and an oblong inner plate, which is narrower and longer than the hatch diameter. These are secured together by three bolts with captive thumb screws. The red and white rope forms a handle to pull the two plates together in such a way that the three bolts in the lower plate line up with the three holes in the upper plate... pure genius! There is the potential for a little water to get in through the holes the rope comes through, you could put a little Vaseline on the rope, but I have not noticed any leakage. The mastfoot/UJ and side stays attach to the aluminium spreader bar, which is positioned at the forward end of the hatch to maximise up wind sailing performance. Access to the front hatch is restricted compared with the usual hatch cover but I was surprised how easy it was to fit and remove. Indeed in cold weather it was actually easier than some conventional rubber hatch covers!!!

The cleats for the uphaul and the sheet are also fitted without drilling. they are attached to the deckline RDF fittings nearest the cockpit using longer than standard bolts. To stop the cleats swivelling a short piece of cord secures the front of the cleat to the adjacent RDF.

The mast foot is obviously to the rear of where most kayak sails would be mounted in front of the compass recess (how this affects paddle sailing is discussed below).


The rearward mount does mean that the stowed sail has a greater overlap with the cockpit. This may bother some. It did not bother me at all.

This is the view forward when the sail is stowed. I was very pleased by how unobtrusive it was. On the production version, the aluminium spreader bar will be even lower.

With the sail rigged on the KCS hatch mount it sailed just as well when running off the wind as when it was mounted further forward on the foredeck.

I also noticed no difference in performance on a broad reach.

However, once on a beam reach to a beat, I started to clatter the end of the boom with the paddle. I switched from a high angle to a low angle paddling style and that solved the problem. This is a limitation of having the sail mounted closer to the cockpit.

Another limitation of the more rearward hatch mount is when beating upwind. You can only point at 60 degrees off the wind with a tacking angle of 60 degrees. When the sail is mounted forward, you can point closer to the wind, at 45 degrees off the wind, which gives a tacking angle of 90 degrees. The formula for working out the pointing angle (p) from the tacking angle (t) is p = 90 - (t/2)

Conclusions.

1. The KCS KY-PRO sail is a very well made small but powerful kayak sail which has superb performance, especially as the wind increases.

2. The KCS carbon mast, boom and stays are well made, light and strong, with great fittings.

3. The KCS hatch mount with mast foot and spreader bar for stays is a brilliantly engineered solution for those that do not want to drill holes in their own boat or want to fit a sail to a borrowed boat. Its downwind paddle sailing performance was unaffected but it does limit pointing angle upwind and cause the paddle to hit the boom if you use a high paddle style going upwind or across the wind. 

Potential paddle sailors now have a choice... to drill or not to drill. What a great addition to the choice of paddle sailing equipment available to kayakers. An innovative and flexible paddle sailing system that both performs and is made in Scotland.

Lastly, the way the hatch mount is constructed, I can see no reason why an existing paddle sailing rig, such as a Flat Earth rig, could not be fitted to the hatch mount.

28th April 2021 #1 Return to sea kayak camping, a trip to the Sound of Sleat and Loch Hourn.

Due to various health problems I have not posted much here recently mainly because I have not gone anywhere. However, I managed to get myself north to Glenelg on 28/4/2021 to join Ian from Mountain and Sea Scotland and friends. It is the furthest I have driven, furthest I have paddled and the most nights I have camped out in over 4 years.

I get easily tired these days and though previously I have driven to Loch Hourn, paddled and driven back in a day, I now stop every hour. I left Glasgow at 6am and my first stop was at the Falls of Falloch north of Loch Lomond.

My second stop was under the Three Sisters of Glencoe where 

the Alt Lairige Eilde tumbles into the glen over a series of three waterfalls. I also stopped at the Spean Bridge Commando Monument but there was no view to Ben Nevis due to fog. A further stop at the Loch Garry viewpoint was equally disappointing, due to a large forest having grown up and completely obliterated the view. Goodness knows what tourists make of it.

A final stop near the summit of the Mam Ratagan pass above Loch Duich gave a splendid view to the Five Sisters of Kintail.

Glenelg lay at the foot of the far side of the pass. We had wondered if we would get parked as all the likely spots are usually taken by motor homes. 

Before we left the cars we asked several locals. It turns out the popular Bernara beach was blighted by a few of the many camper vans who visit staying for weeks at a time and dumping sewage onto the beach. The community erected a 2 metre barrier which has kept all camper vans out. That is unfortunate for the responsible owners but was fortunate for us.

Soon we were loaded up and ready to go, though the tide was a long way out as it was spring tides.

My brother Donald came along in his small 2.75m Rib and 6HP outboard... the Guppy. He has made a video of the trip.

Soon we were on our way with an increasing tail wind.

An RAF Typhoon banked overhead and we could see the pilot looking down on us then

we got a cheery wave from the local prawn boat OB164 MAIREAD M. I hope everyone was happy to see the return of tourists.

The wind quickly picked up and my camera stayed in its dry bag. The GoPro did capture 

some of the sense of freedom after the long winter lockdown.

All too soon it was time to drop the sail and land on our chosen spot for the night, an offshore reef with a white shell sand beach.

It was now spring low water so we had a long carry.

 
The kayak crew were Ian, Allan and his wife Lorna and his brother Raymond. My brother Donald had motored the Guppy round to the lee side of the reef where he would line it in as the tide rose. We were set for our first camp together in quite a few years. Our end of lockdown adventure had begun.

Doug and Lara Cooper have just launched a new Scottish Sea Kayaking website. Already a huge amount of work has gone into it. It will inform visitors to new areas of many alternative places to go, other than the over visited, well known honey pots.
A good number of people criticise guides like this. I admit I did not think the Bothy book was a good idea at all, especially when some of the recommended parking places led to estates closing a gem of a bothy such as An Cladach. However, bothies are a very finite resource, unlike the sea which is pretty infinite compared with the number of sea kayakers.
Why I like this website is that it is very comprehensive and will undoubtedly spread the load of sea kayaking visitors across a much wider area. What is finite on a sea kayaking trip is car parking. I hope as the site develops, Doug and Lara will highlight as many different parking/launch sites for each trip as is practical.
Well done Doug and Lara.

Edit: I have been in touch with Doug and they have intentionally decided not to put car parking, launch sites and camp sites in the website. Doug has also said that future editions of the Pesda guides will not mention camp sites, which are another finite resource. I am pleased about that. In my www.seakayakphoto.com blog, I always avoided saying where any of the campsites or bothies we visited were. I also made sure that I did not post a GPS track that ended on a campsite!

P&H Valkyrie, a long term test and review.

Introduction

An edited version of this review appeared in Ocean Paddler Magazine issue #71. I have also published it several times on Facebook back in July/August 2019 but of course Facebook is useless for anything you ever want to find again. I keep getting requests for a copy of the Valkyrie test so here it is on good old fashioned Blogger where a Google search will find it!

P&H do not have a composite fast sea kayak (FSK) like the Taran or the Pace in their lineup so the arrival of the RM (rotomoulded plastic) Valkyrie has been much anticipated. The hull shape of the Valkyrie is based on the excellent Pyranha Octane/Think Nitro RM surfski, which was tested in Ocean Paddler magazine #58. I enjoyed paddling the Octane so much that I now own a carbon fibre surfski! The prospect of an economically priced “fast” sea kayak, built from tough RM is very enticing, particularly for those solo paddlers who like covering the ground fast on circumnavigations where rocky landings and launches are difficult without help. So I had great expectations of the Valkyrie! 



Although surfskis are fast, they do have significant hull differences to typical FSKs like the Taran. They have much more overall stern rocker which starts at the cockpit. This helps them catch fast waves and also loosens the rear end so that a relatively small rudder can correct an early broach and keep a surfski running fast and straight down the waves. Surfskis also have a much more tapered (and so low volume bow) than an FSK. The taper starts at the cockpit. In comparison FSKs are more parallel sided and carry significantly more volume towards the bow. Surfski bows are designed to pierce the wave in front and not slow down ((especially when planing down wind). Traditional seakayaks with flared bows (and to a lesser extent FSKs with parallel vertical sides but higher volume bows) tend to rise over the wave in front more than a surfski. This increased pitching causes deceleration but gives a much drier ride.

Test conditions and paddlers.


The Valkyrie was paddled nearly every day for six weeks on the Solway coast of SW Scotland. Conditions varied from flat calm to very rough with winds up to F5/F6 against the tide. Offshore the spring tidal rate is 4 knots and there are tide races at the headlands and round the islands where the flow is accelerated. Prevailing SW wind against ebb spring tides (which are nearly 9m high) create breaking waves, which stretch out well beyond the emptying bays. During the seven weeks testing the Valkyrie, rescue services (including cliff rescue coast guards, two lifeboats and a helicopter) were called to five separate incidents in the area involving kayaks and small dinghies and boats. All in all, these were ideal test conditions for a boat like the Valkyrie. The main tester was 73kg and 172cm tall. Five other testers (who varied up to 92kg and 190cm) paddled the Valkyrie though the largest paddler could not paddle it far due to being too cramped for his 84cm inside leg/size 46 feet. Paddler experience ranged from advanced to occasional summer paddler. It was paddled with a mixture of wing and Euro paddles. It particularly suits wing paddles which were used by the more experienced testers. During the test the Valkyrie was paddled alongside a Taran 18, Taran 16, Atlantic RM, Cetus MV, Scorpio MV, Aries 155 and Think Zen surfski.



Construction and Fittings.


The Valkyrie hull is made of CoreLite X and is remarkably stiff and light for a RM boat. In comparison with its Octane surfski sibling it is still remarkably stiff, despite not having the Octane’s longitudinal foam stringer. Despite its length, this is the stiffest RM kayak I have paddled. A good test for stiffness (you can try in a kayak shop) is to get someone to help you carry it, one on each end. A soft boat will “boing” as you walk. The Valkyrie does not. It has been built light (the one I have on loan weighs 26.5kg including two extra optional hatches) but my experience of CoreLiteX on a series of demo boats is that it is more than tough enough. Standard of moulding is exceptionally high with very well defined water release planing edges to the under hull. Composite kayaks and surfskis  tend to lack these sharp edges as they would be too fragile. I am sure much of the exceptional downwind planing performance of the Octane/Valkyrie is due to these. The surface finish of the hull is a mixture of matt and gloss plastic, which looks very smart. I was delighted that the sides of the bow and the back deck were gloss as these make excellent mounting areas for suction action camera mounts (which do not stick to matt plastic).  

On the foredeck there is a compass recess and a flat to mount a mast base for a sailing rig. A pair of deck line RDFs are fitted laterally to the flat to mount side stays for the mast. Unfortunately, this borrowed kayak lacked the other fittings for a sail so I was not able to try it out paddle sailing. The Octane which I paddled in 2017/18 did have a sail but I felt that it was unnecessary and an encumbrance on an open cockpit surfski. However, I think a sail on the decked Valkyrie would be very manageable and great fun. It could make a great difference, especially if loaded with camping gear. The boat comes with good sized Pyranha alloy carrying handles at bow and stern and a security/tow line mount behind the seat. The carrying handles are streamlined and at the bow create much less spray than end toggles would. The test boat was one of the first out the mould and was leaking at the stern where the hull is pierced by a tube for optional end toggles. The manufacturing problem has been identified and has been corrected on production boats. 

There is a full set of deck-lines and deck elastics. The deck elastics on the foredeck wrap round the front of and interfered with closing the forward mini hatch. I addressed this with a bit of cable tie to hold the elastics forward of the cover.  A clip will be supplied with production versions. The seat is mounted really low and can easily be adjusted 6cm fore and aft with thumbscrews, which screw into threaded inserts on the bottom of the hull. The backrest has ratchet adjusters attached to the thigh grips.  The footrests/rudder pedals are the very easy to operate SmartTrack system and can be adjusted using wands with extend rearwards. These are easy to reach and operate. The rudder cables adjust for footrest position automatically. The rudder is the excellent SmartTrack over-stern unit. It is fitted with a 28cm rudder, which extends 22cm under the hull. The KajakSport hatch covers all fitted easily and were totally watertight. 


Paddling the Valkyrie.


My first outing in the Valkyrie was a pleasant F4 to F5 wind over an ebb tide. Within the first 5 minutes I was totally hooked by the Valkyrie’s speed, performance and ability to generate fun. It has a lot more primary stability than the Octane (which has a surfski’s higher seat to maximise paddling efficiency). As a result I had to shorten my paddle a bit compared to what I use on surfskis but the Valkyrie was only marginally slower on flat water than my Think Zen Ultimate carbon surfski. Paddling out through steep wind over tide waves it was a much more comfortable ride than on the carbon Zen, which slams and shudders in these conditions. Obviously being 16kg heavier than the Zen, it lacked acceleration in comparison and downwind I missed a few waves I would have caught on the Zen (which in a race would have been critical, but not when just having fun). However, once on the wave, the speeds were very similar. It would be difficult to find a faster kayak than the Valkyrie without spending a serious amount of money. One feature I am glad has been carried over from the Octane surfski is the paddle cut out on each side of the hull in front of the cockpit. This allows paddle entry as close to the hull as possible enabling a very efficient stroke. However, it does impinge on the room for your feet. I had to come in and change my size 43 Lomo boots for my much neater windsurf boots.

One of the other testers (with a Northshore Atlantic RM) would like to buy a Taran 18 or Pace 18 for fast touring expeditions but has just bought a house and has a limited budget. He was keen to discover whether the very affordable P&H Valkyrie might be a rotomoulded plastic equivalent. The short answer is yes the Valkyrie is a fast (very) sea kayak but it has three significant differences to mainstream FSKs, like the Taran. Two have been mentioned in the introduction. From its surfski heritage, it has more stern rocker and a more tapered, lower volume bow than FSKs. The third difference is its overall volume is significantly less than an FSK. The Valkyrie volume is 334l which is almost 50l less than a Taran 18 (383l). Not surprisingly these design differences create performance differences between the Valkyrie and other FSKs.

First of all the increased stern rocker makes the Valkyrie incredibly quick to turn after going out through waves. I have paddled the Taran 16 more extensively than the Valkyrie and the Taran 18 a bit less. In both Tarans the turning circle is such that I would look for a wide, flat spot between bigger sets to turn in so that I could set myself up ready to catch the next big wave. Even though the Valkyrie I tested does not have an under hull rudder, it still turns like a surfski.  (An optional understern rudder will be available soon.) I could turn tighter and faster than in an FSK, starting just in front of an approaching bigger wave and still have a good chance of catching it. The increased stern rocker on the Valkyrie (and surf skis in general) also means it is easier to catch faster waves and once on them, it is easier to steer diagonally across them without broaching. Many who paddle British style sea kayaks only manage to catch waves when they slow down in the shallows and form surf. Faster deep water waves just pass under such kayaks’ hulls. Paddling unloaded alongside a Taran 16, Scorpio MV, Cetus MV and Aries 155 the Valkyrie consistently caught more waves and disappeared ahead. Swapping paddlers with the Taran 16, the Valkyrie still had the advantage. The downside of the increased stern rocker is that on flatter water the Valkyrie is not as fast as an FSK. 

Above: comparison of distribution of Valkyrie hull rocker with a typical FSK (Pace).

Also although the Valkyrie is more manoeuvrable than an FSK it is more rudder dependent. With the rudder up the Valkyrie weathercocks significantly more than an FSK like the Taran, making it very much harder to paddle. The Taran 18 owner disliked this feature of the Valkyrie, especially as he normally surfs the Taran with the rudder up. I had no problem with keeping the rudder down in all conditions except reversing into caves! Second, the reduced volume bow of the Valkyrie compared to an FSK means that the bow does pierce through short, steep waves rather than rising over them, even when unloaded. This happens in surfskis too but most of the green water washes off the smooth deck before the cockpit. Unfortunately, on the Valkyrie the water hits the raised forward hatch cover and sprays everywhere including your face. Third, you could not carry as much gear for a long expedition in a Valkyrie as in a Taran or Pace due to the overall reduced volume. However, if your plan was for a weekend outing, say to a distant headland with a tide race or some decent swell curling round, then the Valkyrie would tick all the boxes, especially if there was a rocky landing involved.

Another advantage of the Valkyrie’s is manoeuvrability combined with its tough CoreLite X RM construction means that I have taken it to places in conditions that I would never dream of taking a composite FSK or my carbon fibre surfski. It is obviously not a specialised rock-hopping tool as its sibling the Delphin but it is reassuring to know that choosing a fast kayak like the Valkyrie does not stop you getting up close to the narrow channels and caves of the rocky bits of our coast!


I was worried that the over-stern rudder fitted to the Valkyrie would be less effective than the under-hull rudder of the Octane. So I decided that a longer downwind run along the exposed Solway coast between Kirkcudbright Bay and Fleet Bay would be a great test. On the day a force 4 gusting 5 SE wind was blowing parallel with the rocky coast and running straight into the tide which was SE going, again parallel to the coast. This created some lively sea conditions. Conventional British style kayaks tend to broach in these conditions and require much steering input to keep on course, which slows your progress. The Valkyrie stormed ahead of the British style kayaks on this coast by running true and straight and not broaching once. It was fun, fun, fun all the way, as one screaming run on the plane followed another. Despite the steep, short period waves, I was not aware of the rudder coming out of the water when running down-wind (it does come out when paddling out against the waves, but that doesn't matter as you are going so much more slowly.) So the Valkyrie has lost little of the Octane's response to the rudder or its ability to turn quickly. On flat water turning around a buoy or when turning between waves for the next run in, you can feel the Valkyrie's stern skidding round as it turns tightly, just like on a surfski.

A couple of the testers have said they would prefer it if the Valkyrie tracked straighter without a rudder. Well, another friend had a straight tracking P&H Quest expedition kayak. He had a Karitek retractible under hull rudder fitted but it proved next to useless for turning such a directional kayak. There is always a compromise with kayak design. The rudder could not overcome the Quest hull's straight tracking. The Valkyrie is designed to be used with a rudder and like a surfski has the loose stern to make it very responsive. Some may ask "what if the rudder fails?" Well the Valkyrie is supplied with the excellent SmartTrack rudder. This is a simple robust design and the Valkyrie is fitted with very strong control lines. I have never experienced or heard of a jamming or failure of this rudder. Whatever, I am more than satisfied that the move to an over-stern rudder on the Valkyrie has lost little of the control or manoeuvrability of the Octane with its under-hull rudder. For those that really want it, P&H do offer an under hull rudder as an option on the Valkyrie but personally I would not bother. 

Despite the lively testing conditions I did not accidentally capsize the Valkyrie once. However, I can report that it is extremely easy to roll and once up quickly settles in the vertical position due to its excellent primary stability. It is also one of the easiest kayaks to do a solo remount on.


Ergonomics
.

One advantage of having a test boat long term is that you can really get a feel for ergonomic issues that might be missed on a short paddle at an open day or symposium. The low seat is very comfortable and gives a very stable paddling position. The paddle cutaways in the hull forward of the cockpit really let you get a clean catch, close to the hull. The back rest was very comfortable and it was easy to adjust to just the right tension so as not to inhibit trunk rotation. I only used the thigh braces when rolling. The cockpit was wide enough to allow a knees together and up position for performance paddling. The boat was paddled by six different people. Four had no problems with foot room but the tallest and shortest had significant problems so this is a boat I recommend trying before you buy. My inside leg is 74cm and I have size 43 feet. The test boat was fitted with the forward mini hatch and my toes were restricted between it and the rearmost lateral fore deck elastic RDF mounting points (which extend inside the hull). I found this to be so uncomfortable that I could not paddle the boat for more than 2-3 hours at a time. During my time with the Valkyrie I made the open crossing to the isolated island Ailsa Craig, a 36km round trip. A fast boat like the Valkyrie would have been ideal, especially since the RM construction would have aided the landing on the granite boulder beach. However, I took a much slower composite Aries instead, solely due to foot comfort. 

With short legs I would order a Valkyrie without the mini hatch but even then the RDF mounts would still get in the way. Four of the six testers had no problems with the RDF mounts catching their toes. The footrests/rudder pedals are mounted very low and the pedal axles slope down and in rather than being horizontal as recommended in the SmartTrack installation manual. The arch of my foot was on the rudder pedal rather than my toes (as is the case with the systems fitted to other fast sea kayaks or the Octane and other surfskis). This is not ideal for performance paddling but a couple of the less experienced paddlers who tried it though it felt great. The Taran 18 paddler and myself both prefer higher mounted pedals. P&H are phasing in an alternative mount which may suit you better *.  SmartTrack also offer mounting adapters.

* P&H have now modified both RDF fitting postions in the cockpit area and the mounting angle and height of the SmartTrack rudder pedals. 


Paddling the Valkyrie loaded. 


I weigh 73kg and to test carrying capacity I loaded it with just over 30kg of camping gear. This was just within the recommended overall load limit of the boat. Packing it proved easier than I thought as there is a lot of volume in the shallow but broad stern. So the Valkyrie has enough volume to carry a fair bit of gear but its performance changes as you load it and it would be easy for a heavier paddler to overload it especially at the bow. Like other Swede form designs, like the Cetus, I found a bias to rear weight distribution worked best. Neither the Octane nor the Epic V7 touring surfski have bow hatches (although both have rear hatches) and my experience suggests that it could be too easy to overload the bow of a surfski type hull. Loaded up In a fresh to strong offshore wind with flat water, the Valkyrie still proved easy to hold on any course with the rudder. In short steep waves its surfski heritage showed a disadvantage to a similarly loaded Taran 18 and Cetus MV paddling along side. The Valkyrie stuck its bow deep in every wave, up and down wind. What was a fun feature enhancing downwind speed when unloaded now caused a very wet ride. So although the Valkyrie has a similar overall volume to the Cetus MV, the slower Cetus makes a much better all round camping and touring boat. 

Wear and tear.


The only sign of wear and tear was some corrosion in the alloy carrying handles where they are secured by stainless steel bolts. This is a common problem with such fittings used in salt water and also affects my carbon fibre surfski. I wash with fresh water after every outing and have used some silicone grease between the bolt head and the handle to try and reduce this.



Conclusions.

So what sort of kayak is the Valkyrie and who it would suit best?  In the current market it has a pretty unique set of features. In performance terms it is fast yet manoeuvrable. Over the last 17 years I have had the privilege of testing some really great kayaks but seldom have I had such fun and enjoyed myself as much as in the Valkyrie. It is the fastest RM kayak I have ever paddled. Down wind and wave most composite British style touring kayaks will not keep up with the Valkyrie and it is also more than a match for FSKs in these conditions. Unsurprisingly given its origins, the Valkyrie is more related to surfskis than to other FSKs. The Valkyrie is a whole heap of fun on shorter trips when it is more manoeuvrable than an FSK in the turn or on a wave and it is easy to catch fast open water waves. However, in a variety of conditions on longer trips an FSK will carry more gear, faster (and drier). Horses for courses perhaps and these days it is great to have a choice. 

Despite its speed, the Valkyrie is not a difficult boat to paddle. One of the testers was an ambitious newcomer, who was paddling borrowed club boats. He went on to buy a Valkyrie as his first sea kayak. I think a big market for the Valkyrie will be as a second or even third kayak. I think it would be ideal for someone who already has (and wants to keep) a conventional British style sea kayak for touring but who also likes to paddle fast for fitness or fun or even enter an occasional race. The Valkyrie is a fantastic alternative for those who do not want to go to the expense of getting a composite fast sea kayak (or surfski). The fact that a kayak with the performance of the Valkyrie is available in tough RM construction is an incredible bonus to those that might not have the nature to care for a lightweight and fragile composite kayak or surfski. It might also tempt some traditional sea kayakers into down wind, open water, surfski type paddling who might not yet be ready to take the jump to a pure surfski. I think anyone has been paddling for some time and is feeling a bit jaded should consider the Valkyrie. Once you get it out in the waves and experience the acceleration and planing as you catch your first fast wave, your paddling will be rejuvenated. I cannot overemphasise how much fun it is. The fun is pretty similar to the fun I get windsurfing, you don’t actually need go anywhere to have windsurfing fun either.

Conflict of Interest.


With thanks to P&H and Sea Kayak Oban I had free use of the demo Valkyrie from 13/6/2019 until 5/8/2019. I have had a long standing unpaid relationship with Pyranha/P&H in which I have access to new products/prototypes in exchange for feedback. I own several personal kayaks from Dagger, Evolution Kayaks, Pyranha, P&H, Rockpool, Think and Valley so I am not dependent on Pyranha/P&H to go paddling!

KCS KY-Pro Explore trolley: test and review, a first look.

 I first bought a Mk 1 KCS Expedition trolley in 2003 and it is still in use at my caravan on the Solway. I have since upgraded my main expedition trolley through various versions and currently use the KCS Expedition trolley Mk 5. I do not just use it for getting the kayak from the car to the beach but use it on expeditions to get on and off ferries, for long road portages such as West Loch Tarbert to East Loch Tarbert across the Kintyre peninsula and for rough off tarmac road tracks such as portaging round the falls of Shiel where the River Shiel pours into Loch Moidart at low tide, the Portage across the Tarbert of the Isle of Jura and the portage from salt water Loch Nevis over the hill into fresh water Loch Morar. So the new trolley has a lot to live up to. KCS can be contacted here.

Unlike the previous incremental changes this is a complete redesign but using similar materials.

The driver for the design was to create a more compact trolley when it is disassembled and in this it is spectacularly successful. 

The previous Mk5 trolley is in the red bag on the rear deck. Admittedly it is not fully disassembled, I just took the wheels off, but it is undoubtedly bulkier than the new model.



The new pads have thicker foam than previous models. A nice touch is the smaller pieces fit right at the top of round kayak hatches and the larger pieces fit at the top of oval hatches.


The parts all assemble without tools. The pads push into place using captive headed bolts which push into retaining slots on the crosspiece. The two axle supports then bolt onto the underside of the crosspiece and this secures the pads. The bolts are attached to the axle supports so you wont loose them and they also have large heads so you can use them with cold hands. The axle spacers are permanently attached to the axle supports. The axle is simply threaded through and the wheels secured with spring axle pins.


Like the previous Mk 5 trolley there is an integrated axle stand. I chose the 10" foam filled wheels and tyres. These do not fit in 10" round hatches. 


However, if you buy the 10" pneumatic tyre option and let a little air out you can "roll" them into the hatch by holding the wheel vertically and pushing one side down into the hatch. Alternatively you can buy 8" wheels but these arre not so good on rough ground.

At the moment I am landlocked due to Scottish Covid travel restrictions ,so I have been unable to test the KY-Pro Explore trolley in the field. So how does it compare with the previous Mk5 trolley? 


Well the good news is that the pads are just as wide and just as long as those of the Mk5 trolley, including the T support pad at the back. This is good news as the trolley should be able to handle rough bumps with a fully loaded kayak without twisting forward if the wheels hit an obstruction. (This was the reason for the extended T pad.)

However, if you are reversing a loaded kayak and it hits a bump, the Mk5 trolley could twist back. I overcame this by cutting a slot beneath the T piece and putting an extra strap through it and right round the kayak hull. Why is this important? When would you want to reverse a fully loaded kayak over a bump? Well an example is on the ferry to the Small Isles. 

The MV Loch Nevis serves the Small Isles. It is not a RORO ferry. There is only a stern door. If there are other vehicles on board and they are not getting off at your stop, you have to reverse your kayak off between them as there is no room to turn. There is a real bump at the ramp so stability when reversing is very important.



On the new KY-Pro Explore trolley I have drilled the rear of the two oval hull supports supports and tied loops of 3 mm cord through. This allows a strap to be threaded through the loops and and then wrapped round the hull to secure the rear of the trolley for reversing over bumps.



This extra strap round the hull, from the rear of the trolley (left in photo), resists the trolley body twisting round the axle, if the wheels hit a bump when reversing the a loaded kayak on the trolley. This extra strap also minimises the trolley twisting so that the axle is not at right angles to the direction of travel, if only one wheel hits an obstruction.



On swede-form kayaks, like P&H which have the wide point behind the seat, I do not bother with a third strap going forward from round the axle then forward on either side of the hull and fastening round the front of the cockpit rim. On fish-form kayaks, like the Valley Nordkapp LV, which has the wide point in front of the cockpit, I do use a third strap, to prevent the trolley slipping rearward on bumpy surfaces.




However, a KCS customer with a fish form kayak was troubled with the trolley slipping back and asked if it would be possible to hook the strap onto the cockpit rim with some sort of clip. So KCS came up with these really neat accessory "S" clips that hold the strap forward. These prevent the strap loosening off if a bump tries to force the trolley back. This makes the strap from the axle forward round the cockpit rim unnecessary.

The photo above is a P&H kayak with a swede form, so the strap would tighten if the trolley was forced back. These "S" clips are not necessary on this type of kayak but will prove invaluable on my Nordkapp LV, which has a pronounced fish form. The clips could be used with any brand of trolley carrying a fish form kayak.


Another improvement with the new trolley over the Mk5 is that the pads sit closer to the axle thus lowering the centre of gravity. This is important with a fully loaded boat on an adverse camber as it makes the trolley/kayak much more stable.

This promises to be KCS's best trolley yet. It is £135 compared to £125 for the Mk5, which is still available. I think the new Explore trolley's  main advantage over the Mk5 is more compact packing. It promises to be equally stable and robust. I just need to get it out for a proper test...until then here are some photos of previous KCS trolleys in action.
