Dont' mess with lightning in a boat.
While it's true that in a car you are protected by the metal frame around you, as it tends to conduct the voltage around, rather than through you, and the rubber tires do give some grounding protection.
But, in a boat it's the complete opposite...YOU are the ground! You're toast (just put the jam in your pockets.)
I've never seen a boat hit by lightening, but a buddy reported seeing one (alum. hull) he said there were hundreds of holes in the hull where the voltage sieved it.
Hey, nothing's worth the risk. The fish will be there another day. Getting dead really sucks.
