The Shark Trust have just produced a Code of Conduct for kayakers who come across basking sharks. You can download the full size pdf file here.
Remain calm and quiet.

The Shark Trust have a basking shark project and would welcome any sighting reports especially when accompanied by photos but remember to switch the flash off, if you use the camera underwater!
