I have painted a Dart20 and a 26 Monohul, along with the decks on my Tornado with both 2 part (Awlgrip) and single part paints (Interlux).
For your situation, I would recommend a one part paint that can be brushed on, and is self leveling. Interlux brightsides, also sold by West Marine as a house brand, is a great paint.
All of this for about $17/quart. The boat that I painted 5 years ago, and that is outside 7 months of the year still looks like new. It is farl less toxic, and far more forgiving that 2 part paints. And, hundreds of dollars cheaper.
I wetsanded the boat with 220 paper before painting, washed it down with wax remover, and primed the boat with interlux primer. Between coats I sanded any brush marks or runs, Especially after the prime coat. If you don't sand the prime coat you will burn through to the high spots when sanding the finishing coat and have a real mess.
Wet Sand primer with 220, first coat with 320, second coat with 600, and then 1200. Alow a few days between coats.
The one drawback of the 1 part paint is that it can't be used on a boat that is left in the water forever, and if you have leaky hulls, the hydrostatic pressure may cause tiny blisters below the water line. They go away when it dries. Only the two part paints can handle this situation.
Be sure to let the paint cure for about 2 weeks before using the boat.
Good luck
