I'd also be most reluctant to jump in the water. A lightning strike can kill swimmers and divers in the vicinity of the strike--the problem is that the charge differential in the water is still enough to set up an electrical flow through your body and stop your heart.

I'd treat it like a lightning storm, and try to avoid contacting all metal on the boat until the boat and powerline got un-contacted.

Powerlines also sag significantly in hot weather, that's how the 2003 national blackout got triggered. I have no idea how the charted clearances account for that.
