If you look at the other Germanic languages, most use either "vehicle" or "boat". As a native speaker born far away from any body of water, I would have said that you could use "Luftkissenboot" and "Luftkissenfahrzeug" interchangeably but the German Wikipedia article disagrees. "Vehicle" apparently implies that it doesn't only need to work on water.
