The Happy Seat Magnum/Happy Thruster Combo is the ticket for any playboater looking to improve their ride substantially. Our team has won numerous events by getting bigger air out of their moves thanks to the Happy Seat Magnum/Thruster Combo. The Happy Thruster Magnum/Seat is a dream come true for any playboater. Try it out and you'll never go back! We haven't paddled any playboat without this combo since they were introduced in '05. When wave surfing we have just enough air in the Happy Thruster to act like an implosion prevention device, and when in a hole, we blow it up for major pop!
