I think Rick may be referring to BOTTOM paint as described above. As I
remember, there is a fairly good selection of marine paint colors.

This seems reasonable - but be careful with varnishes, as they will
yellow. Epoxy sealers will break down in sunlight.

There are also a few fast-drying varnishes that may speed things up a
bit. If the boat is in the water and you're sitting on the dock, or in a
dinghy, you could rig up some sort of screen to block any splashing.

Those 'ole sea dogs'll probably have a few good suggestions.

Sounds like a fun project - next thing you know you'll be redoing decks.
