What exactly are you wanting? RPGs about the ships, the sailors? Realism, pulp? What?
Why not GURPS?

>>54117261
ALWAYS expect GURPS

>>54117261
There are some pretty good Naval wargames that will do better

GURPS kinda' sucks for vehicle combat

Cumbersome and scatter

Falls back to just good if the PCs are officers on a single ship, desu. The 4e Spaceships line can also be used to make naval ships, there's examples floating on the GURPS forums, it seems to work well.
