Imagine you are at the edge of the sea on a day when it is difficult to say where the land ends and the sea begins and where the sea ends and the sky begins. Sea kayaking lets you explore these and your own boundaries and broadens your horizons. Sea kayaking is the new mountaineering.
One of the great problems of sea kayaking is trying to look cool in all the gear required to survive the Scottish winter. Simon has done a passable job except for that necessary evil, the spray skirt. I call it a skirt not to beat about the bush (as some commentators do) and call it a "spray deck".
What a euphemism but even in Scotland, land of the kilt, we are usually adverse to calling it a skirt. To Simon's great credit he is wearing his with as much aplomb as possible in a public place.
