It sound like you had a problem before the move too. The problem may be with you boats dc system. First, connect a wire to a zinc, hang it off the boat, and connect the other end to your dc ground. This will protect your boat until you get things fixed. Then test for a stray leak. Shut everything off, and disconnect your battery grounds. Use an ammeter to remake the ground to battery connection. The ammeter will measure stray currents. Check your circuits which are left on all the time. On my boat, that is just the bilge... I used this method to tract down a short in my instrument line.
As for diving in the water, don't worry about your heart stopping. The currents for galvanic corrosion are tiny. Measure it with your ammeter if you want.
