1) A fluorescent light on board has some tricky wiring.
2) The old phone magneto you've been using to catch fish wasn't turned
off while you weighed.
3) The fresh breeze off your synthetic sails has been building charge
on your glass hull with no sea grounds
4) Unfriendly SEALs?
5) Leaky submarine power line
6) Other....

A few years ago while cruising, I was weighing anchor, and when I got to
the
chain (no windlass then) I was shocked, not by what was on the hook, but
as in
electrical shock. I dropped it and pulled it in again with the same
shocking
results. It wasn't a killing shock, and as the hook was clear of the
bottom, I
motored off enough with the hook in the water to be sure I didn't pick up
a
live cable, then hauled it aboard, getting shocked as I did it.
Before I tell the cause, any guesses?

You've got an aluminum boat. The chain made a great conductor to ground.
Your boat had an electricity leak of some sort which was unnoticeable
before, as you were in the faraday cage of its hull, but you were barefoot
or otherwise adequately conductive when you were hauling up barehanded and
the chain completed the circuit.

Howzat?

It's a fiberglass boat, and you get shocked even with the motor not running.
