Thanks! Nerroth I have this very thin theory on how this should work, but this was mainly a design effort, so the treknobabble is limited. 
Anyway the ship has a warpcore onboard, and a couple of impulse engines as well. To get somewhere quickly I would use warp, when in a sytem use either the sails or impulse. The sailing method is 100% silent, with a short "woosh" when the ship is changing direction.
