I've seen a couple of really cool new products that may have a place on a wakeboard boat near you.
First is
www.LiquidCaddy.com becuase you never have enough beverage holders. They attached to the tower or windshield or . . .
Last but not least is
http://www.re-coil.com which is a retractable/rewinding rope storage reel. I just got mine and am ordering at least one more!
