So, large, solid caravels, cogs, and other such things, probably. I think hobgoblins would build sturdy, fast ships designed for ramming and boarding procedures.

so I thought I'd pick everyone's brains for good ideas. I'd like them to be racially unique from the human or elven designs, but I'm not sure where to go with it. The problems with the orc and hobgoblin ships are not only that I have no ideas for names, but also no ideas for what these vessels would look like. So when my players ask the name of the vessel they just captured, they'll get a blank stare from their DM. However, I have no idea what constitutes a good elvish name for a ship. Their ships are small and fast, light in armament and using spellcasters as their main offensive weapon. The elves in this world are tend to stay to themselves, but react angrily and raid human coasts when provoked. The elves I already have a concept for their ships.

gnomes appear here and there, but aren't big enough to have their own fleets). The problem has been the ships of the elves, hobgoblins, and orcs (the three other major seafaring races.

I'm basing them rouhgly around 16th/17th century ships. Well, I'm doing a campaign this fall that will have the sea as a central theme, (using the ship rules from Corsair, cannons allowed, and creating vessels as needed) as as such, there's going to be quite a few ships around.
