Transparent boat, or rather a hybrid canoe-kayak will allow through what is not available in a normal boat - under your feet will be visible sand bottom, will float fish and turtles.
This canoe-kayak hybrid has a transparent polymer hull that offers paddlers of all levels an underwater vista unavailable in conventional boats. Only available from Hammacher Schlemmer, it seats two people within a sturdy hull made of the same durable material found in the cockpit canopies of supersonic fighter jets. The vessel supports up to 425 lbs., displaces a greater amount of water for more surface stability, and paddlers sit lower to the deck, resulting in better balance.
A drop-down skeg keeps the craft on a straight course when needed. Adjustable seats allow paddlers to personalize their leg room for a comfortable day’s paddle and the lightweight watercraft is easily stored or transported. Includes framed back and front seats, two fixed transparent paddles, and one flotation device.
If you want you can buy this boat (about $2500).
