http://creekcompany.com/indivdisplay.php?primaryAutoID=249&Cat=2 I love the tube, its a lot safer getting in and out than the round ones. Ihave a 6' pontoon inflatable, it nice but here on the prairie we catch a lot of wind. The u-bot is better in the wind , and its like fishing from an easy chair. Hope that helps.
