As a new 250 owner, living in the lightning capital of the world, I suddenly wonder ....what if i get caught out this summer during one of our frequent afternoon thunder storms. Is the mast grounded in anyway...? if not are there any fixes thet you guys know of...?
Thanks....In my old 22 I used to clamp a jumper cable to a shroud and throw the other end in the water...Probably didn't do much but sure made me feel better...

Say your prayers and write your will!

I just get in the aft berth and read 'till it blows over.

You're right, throwing a jumper cable over the side does nothing when we are looking at millions of volts. You would need to have a very large and heavy copper grounding plate on the under side of the hull. I'm in Jax-FL and have been in plenty of storms. If it gets very bad, hove to and hunker down in the cabin but away from the mast and compression post. Sailors are not killed by lightning becasue the mast takes the hit and then the charge jumps to ground in the water. Fisherman get killed much easier because the body takes the hit. Most times that I have heard the lightning may put very tiny pin-holes in your hull. And of course ruin any electronics. If you do a forum search you will find there has been plenty of discussion on this topic here.
