Also known as the Sea Cow Lightly Used. Some wear on the tail. No rocker , medium concave, my opinion Well made board, very stiff, I lengthened the wheel base to 31’. Made of Birch, Bamboo and Fiberglass. Even though it is classified as a speed board, I used it mainly for push, pumping and carving. Only reason for selling is, I am sidelined for a year.
