It's been a while since I wrote up the stats for those, but I believe I based costs loosely on Vehicles 2e while I based top speed on real-world vehicles. Hovercraft are not particularly streamlined and suffer greatly from drag from their ground-effect envelope combined with the fact that they operate at ground/sea level instead of being able to gain altitude and operate in thinner air with less drag.
