The best bottom paint I have ever used in this are is Pettit’s Trinidad. It is an expensive paint. Perhaps one of the most expensive, but the incremental cost isn’t that much compared to other paints. And, most importantly, it actually works! Even for a cruiser, boat speed is important. Without it, a boat just won’t perform at all to windward under sail. I know a lot of sailors that prefer to motor to windward, but a gross bottom isn’t helping you there either.
All that side, I have yet to find a solid solution for keeping growth off of my prop. Maybe I sail too much and don’t turn on the engine enough? This season I’m going to try Tef-Gel on the prop. This is a great isolating material for fasteners, let’s see what happens here! If you decide to try it, make sure to wear gloves when you put it on. I’ll keep you posted on how it works.
