Transparent Canoe/Kayak

Look at this beautiful transparent canoe-kayak hybrid from Hammacher Schlemmer:

Its polymer hull - made of the same material used in the cockpit canopies of supersonic fighter jets - provides a complete view of all the underwater life forms as you paddle along the surface.

I love sea kayaking and have had the opportunity to cruise the waters in New England, Southern California, and the Florida Keys (complete with manatees) and can only imagine how much cooler the trips would be in this rig.
