Its high performance design is skim inspired. Three interchangeable fiberglass fins on the tail combine with a small tip fin to help spin 3s. A molded kick tail and arch support help with board control. An EVA tip protector not only protects your board, but also your boat. EVA pad on top. Compression molded. An instructional DVD, "Learn 2 Wakesurf", comes free with every CWB wakesurfer. Tsunami 57: 57" x 20.8". Weighs 7.7 lbs. One size fits all.
