Or rather, the silly buggers who tries to cross fjords with them...
Please raise a paw anyone who knows a working 'self rescue' technique for after the thing has capsized in the middle of a fjord...
(I see them every year when I make the trip across to some islets about half a nautical mile out. Of course, I use a kayak and have lifepreserver, self-rescue equipment, flares, a cell-phone in a waterproof bag... )
