Hmmm, okay, let me clarify my situation a little.
I'm (hopefully) going to be starting a new campaign (3.5) where the setting is heavily seafaring. The main human kingdom is an archipelago and the nearest large continent is several weeks' sailing away. Elves live at sea (their Atlantis-like island sank/blew up, and now they are wanderers).
There aren't any aquatic PC races or anything like that (pretty much just core rules). I need some decent rules for types of ships, travel by sea, sea combat, and the sailing/running of a ship. Stuff like new crunch (feats, skills, spells, etc.) is not so important.
