Sealander. No need to decide between the camper or the boat: the Sealander is both. This German-designed amphibious mini-camper is light enough to be towed behind your car and offers the option of camping beside the lake or floating on it. Simply mount an outboard motor to the stern and the Sealander is ready for your voyage. $20,000
Powered by a twin-cylinder Hirth engine, the Golf Cart Hovercraft's nine-blade axial-flow ducted fan propels the craft up to 45 mph and off the ground without harming grass, allowing immediate crossing of a pond or stream to follow-up a cross-water shot.
