I Want One of Those: Roll-A-Yak

Rolling a kayak is crucial for safety but tricky to learn. The Roll-A-Yak adds weight to the keel to maximize angular momentum and minimize rotational inertia, making the kayak easier to roll. The neoprene-covered weighted device cut average learning times from 11.8 hours to 90 minutes.
