Hobie Cat
Hobie Cat 21

The Hobie Cat 21 SE has the same hulls than the 21 SC (Sport Cruiser) with equipment and sail plan more efficient. No more cooler built in hulls but a spinnaker very well sized. The Hobie Cat 21 SE is a fast catamaran but less sporty than the Formula 18, the wings and the consequent width allow her to navigate quickly without necessarily being on the trapeze. In fact, fast and comfortable, she is well suited to coastal raids. The choice of centerboards is also consistent, balancing performance and ease of use.
