[Rhodes22-list] advice on ground for battery

[Hank]

This is a bad idea!!!  Grounding your electrical devices through the
water can cause lots of corrsion due to bad electrical connections
within marinas and other boats.  Most marinas these days are a "hot
bed" of electrical current.  You want your electrical devices isolated
from all of this or you will greatly increase galvanic corrosion.

Again, read the article at http://www.sailmail.com/grounds.htm
for a better explanation of this.
