Thanks Dave, I was really worried about sailboats but never took the time to think or ask about it. It is clear then that the grounded mast is not in contact with water to drain the current because that would attract all lightnings. This means that the boat insulation makes the mast stay at a floating potential different than ground and therefore is not a good path to ground. The same might apply to a kayak, with lower insulation level being smaller, as long as wet paddle is not in the water. Could that suggest that in a thunderstorm, while in the water, one should not use alluminum shaft paddles and keep the wet paddles out of the water, and horizontal, so that one is also a floating point?. I wonder if there are some data of kayakers hit by thunderstorms in the sea. Maybe plastic and fiberglass kayaks are good enough insulation to protect kayakers form lightning.
