The Crystal Explorer from the Crystal Kayak Company is a canoe-kayak hybrid made out of totally-clear Lexan. The polymer hull is designed to act like a large snorkel mask that pierces the surface tension of the water, allowing users to see fish and coral underneath while remaining safely on the surface. The kayaks are eleven-feet long and just under three-feet wide, and are designed to accommodate either one or two people. The design includes high sides and the open cockpit of a canoe, while users can paddle the craft as if they were in a kayak. A low centre of gravity helps with tracking in the water, making it easier for beginners to use.
