Re: Bottom Paint Recommendation
Prime the bottom per manufacturer, and then use a good ablative antifouling paint with enough copper to ward off the growth. Warmer water requires more copper, and perhaps an anti slime addative. Non-ablative paint looses it's effectiveness when the boat is on the trailer.
I like the store brand AF paint. These are made by interlux or Pettit, which are both good brands. If the boat is older, you might want to prime with a high build epoxy barrior coat to ward off any blistering. The newer boats tend to be resistant.
