Channel Islands Semi Pro Surfboard Model Description: The Semi Pro Surfboard from Channel Islands combines Kelly Slater’s favorite aspects of the Tangent and Proton. Kelly designed the Semi-Pro on the computer from start to finish. Riding it to three WCT wins and a 10th world title, his design proved itself as the ultimate all-around shortboard. The Semi-Pro should be ridden shorter than usual: Kelly likes to ride them with his normal dims but his same height (5’9”). This shorter rail allows for his tight signature arcs in the pocket. Deep single concave make the board work best on rail, and ample rocker allows for deep gouging carves. With the wide point 2 inches behind center and increased nose-width, this board still handles mushy days. The Semi- Pro is changing the way professional surfers ride their boards. Experience: Intermediate – Pro. Ideal Wave Size: Waist-high to well overhead.
