The collectible game Pirates has a very simple set of naval rules that could be adapted to D&D
One thing to consider, while historically before gunpowder naval battles were decided mostley by boarding actions and were fights between galleys in D&D world sailing ships would be effective and use magic to destroy the rigging.
Also naval action is slow enough that rituals should be effective.
