Ask a local diver. They really know what paint works the best in your waters. (Shout out to Matt

Our waters promote hard growth (barnacles) as well as green and red furry-slime and lord-only-knows what that leafy stuff is officially named. I can tell you from experience that without AF paint, baby barnacles start growing in a week if you don’t sail the boat.
In SF Bay, California, we can leave outer boats in the water year round. the best hard performing paint is Petitt’s Trinidad SR. I get almost two season with it. When I have to call the diver more frequently than every 8: weeks, it’s time to repaint.
The best trailerable paint around here is Micron 66, which is semi hard and can be left in or out of water for long periods of time. This is my first time keeping a trailerable in a slip, so I can’t tell you how long until I have to repaint.
My trailerable came with Hydrocoat on it and I put another coat on before I put in in a slip. The paint wasn’t lasting 3 months between dives after about 10 months. My diver Matt advised me to try Micron 66, and so far it’s been in the water 10 months and it’s still looking good on a three month diving schedule. We aren’t sailing much since the Covid-19 restrictions were enacted, so it is a bit slimy looking, but I expect that will come off when we sail. There are no barnacles.
