Re: Battery Sizing - am I crazy?
.....Never buy a marine battery for your boat unless you absolutely can't fit a GC.
Not so fast. I have nearly 20 batteries aboard and can't either take them off or keep them routinely charged over the winter. AGM or Gel are the only way for me. I have the later for my house bank, as the charging system was spec'd that way from the factory. All others are AGM, expect one. The dinghy start battery is a plane old maintenance free tractor battery. It was $30 and I'm happy to buy a new one every year, compared to the cost of a marine battery. This winter is the first experiment with it. One season is breakeven, two seasons is a winner. For $30 and breakeven chances, I'm willing to go for it. Not on a house of golf carts.

In the harsh marine environment, something is always in need of repair. Margaritas fix everything.
