Hovercraft in style. Powered by a 4cylinder automotive engine, the UH18SP is everything you'd ever want in a hovercraft. It was designed for people who love to play. For the family that gets together for fishing, skiing, cruising and allaround fun, this is your vehicle. The UH18SP will take you places other craft have never been. Convert your UH18SP hovercraft into the 18SPW Hoverwing™ in less than twenty minutes and fly up to 10 feet high over waves, rocks, beaches and fields in ground effect. The wings roll up and can be stored aboard the craft for easy transportation and rapid deployment. The UH18SPW Hoverwing™ is the only groundeffect hovercraft to be released as a plan or kit. Ground effect hovercraft operates over any terrain while cruising at an altitude of 4 to 12 feet. Home made from plans available thru Universal Hovercraft.
