Or perhaps a Flettner-wing sailing ship...
The thing is, though, the environment never seems to play any role in starship propulsion. Our heroes never discuss "winds" of any sort, or subspace density, or even gravity - unless something catastrophically fails and for a rare once throws the ship at the mercy of the environment.
Sure, perhaps the basics of starship propulsion are to be found in environmental factors, but of the sort that stay absolutely constant (except when they are weekly anomalies driving the plot) and thus never warrant dialogue mention. But anything known to today's physics fails that test... Gamma rays or dark matter density aren't homogeneous and dependable.
