This is another small wave thruster. It's also a small wave enabler. It's short, extra wide and thick, with a wide squash tail, a hard edge and some fins. Originally a tri-fin it now comes in 5-fin. Why not? The bottom is clean with a shallow single concave running all the way through. Proven and tested in small summer surf at the shark park and other local Florida surf spots. This model "as is" is sure to be a favorite. Not much to change or add except getting your liters right and/or maybe adding a small set of tail channels for some extra speed.
