The S-Quad is a high performance Quad (4) finned surfboard. This model is made to ride fast and hard strapped or unstrapped in a wide range of conditions. But when the surf is pumping and the winds are side to side-offshore, this board feels right at home. The four fins make the S-Quad positive when pushing through high speed turns in larger waves. Yet the board is very loose when quickly transitioning from rail to rail in smaller waves. The S-Quad utilizes Cabrinha's exclusive cork sandwich layup. This eco friendly construction provides a light weight, durable alternative to PVC reinforcement while delivering a softer, flex.
