A whole new addition to our spraydeck collection offers a whole new dimension, literally. Unlike traditional spraydecks with flat deck part, WHALEBACK is shaped to fit the cockpit better so it does not slip off the boat even in the toughest conditions. Elastic Supratex protects critical areas from abrasion. Silicon coating on the inside adds on the waterproofness of the spraydeck. Adhesive print in the waist area prevents a cag from rolling up.
