The entire wind series is designed for speed; they are the fastest sea touring kayaks in the Tahe Marine line. An excellent choice for marathons, exercise trips and longer expeditions, the Winds come in 4 models, starting with the Wind Solo at 16'7", followed by the 535 at 17'7", and the fastest; 585 at 19'2". The Wind Duo is a tandem sea kayak meant for competition but also well-suited to every day use.
