I was wondering this very thing?!?!
I think the hard part would be insulating yourself so you are the least likely path for electricity to flow through...Hard to do when you are at best inches above the water, and everything is wet with salt water!!
I will ask a few friends at the Ham Radio club (and post info)....A few are real sharp on this stuff (Practical, and theoretical), although I think I know what they are gonna say!!!
