A 'Roc' is a giant mythological eagle, large enough to carrying away men and horses and sometimes even larger prey. Would be good as either a bomber or a gunboat.
A nice ship indeed. Sometimes, the simplest solutions are the best ones.
Those are the ships i like to see. Like the RH bomber, this one looks so Vanilla-ish, that you have to have played vanilla to know that the ship is not original.
