Brothers Andrew and Kevin have always wanted to combine their two favourite activities at the cottage: water sports and relaxing on their deck chairs. The boys concoct yet another one-of-a-kind Brojects creation: the Chair-Ski – a deck chair on water-skis that can be towed at break-neck speeds with a motorboat. As always, Andrew wants to take it one step further and decides to add a jump, and as always, Kevin disapproves. Join the boys on as they embark on their wackiest (and wettest) adventure yet.
