A Solar Brigantine?

Brigantines were brought up in another thread discussing new classes of ships for the game. They were a ship with a large crew and sails and oars and could both sail or row in the calm. It got me thinking about how you would adapt that to SF since the stand out feature was two methods of propulsion: what about a solar sail combined with one of the other methods in KHs. With chemical engines it would be a lot of free propulsion in the inner system and could make a system ship just that much more economical. With atomic (even ion) you 'd have interstellar capability but would be able to shut down the engine and maneuver by sail, presumably for the purpose of stealth I guess.
