how much paint

We use almost two gallons to do two coats on a 270.

I don't think you will get two coats on a 208 from one gallon. Certainly not three coats. I'd guess two gallons for three coats.

JMHO,

Will one gallon of antifouling paint be enough to do 2-3 coats on 86 204c?

It depends a bit on the paint but I can get 2 coats on a 208 with three on the water line. I still have about a quart left. That is for paint like Interlux CSC. I used Petit Hydorcoat this year and it covered less. I still got the job done but I didn't have much left over.
