Bottom Paint for Highfield Dinghy

[Ranger2727]

I bought a Highfield Dinghy with a 15hp motor and will be using it in the Bahamas for several months. It stays in the water most of the time. Previously the HIB was fiberglass and I just scrubbed the bottom maybe scraping the barnacles. I am now thinking about bottom paint, but am uncertain as to which paint to use. 1) the bottom aluminum is powder-coated, 2) some of the Hypalon is in contact with the water, 3) I will be storing the dinghy on deck and don't want bottom paint on me or the deck.
