Most say that it’s like floating on nothing. While this hybrid looks fragile it is actually made of the same clear, tough polycarbonate that is used in bulletproof glass.
The fun 40-pound vessel has an aluminum frame and adjustable seats. Manufacturer’s tests show that on a clear day passengers can see 75 feet down in the water. Doesn’t get much cooler than this ! I found one at Hammacher Schlemmer for a pretty good deal.
