If your time underway with bathing your hull

Having owned a couple, I can tell you prep is everything. It is not practical to sandblast rust areas since it would dust all the boats around it in a marina. I use to clean the area to bare metal. Use an inhibitor, then use strontium chromate epoxy
, followed by LPU or a good single
part enamel. I'm not even sure chromates are legal
anymore. Back in the 70's we used epoxy coal tar.
