Large Vehicle Based Combat?

Recently I've been trying to think of a good way to integrate combat based around Large Vehicles that are controlled by multiple people together (ei: Boats, Spaceships)
I've been wondering if anybody had any good ideas on how to do combat like this, and if they can give me any tips.

You could assign the players to certain roles like navigator, pilot, gunner and such and just handle their turns like normal, just that they not make actions with their character, but for their station on the ship instead. So the pilot could fly an intercept course the navigator plotted first and the gunner shoots at the enemies. I´ve played a game once while one player made rolls for driving a jeep while we others rolled for shooting at the Nazis that pursued us, for example.
