I live on an 83' wood boat. I've been painting wood boats for a long time. I had a marine
business. Almost any primer ok for wood will work fine. I like a thick primer because it covers many imperfections and I can prep with 80 grit sanding
disks. I sand the primer with 120-150 grit. Once the primer is down any good surface paint will do. If white, generally the more expensive, the whiter the white.
I use Pettit Ezprime because it sticks well to wood and also can be used to paint over old finish coats that are cracked and rough. It sands well,and drys quickly.
On my boat I use Interlux Yacht Enamel. It's not as bright white as Perfection or Brightside, but flexes better. Especially over planks and seam sealer. Places I want really hard paint because of wear, I add 1 quart of traditional varnish
to each gallon of finish.
I do like the more expensive epoxy
primers and finish coats but rarely need exactly a quart or gallon. Odd volumes can be hard to mix right and seal the remainder. My hull will outlive me anyway.
MY hull is copper plated. 100% copper alone doesn't stop marine growth. If you want a clean bottom, go somewhere that has no EPA like the ships do.
