K2 Fiberglass Keel
TWinzer fiberglass k2 keel
AMT twin
The AMT was designed by legendary Channel Islands creator, Al Merrick, for Rob Machado’s Robber model surfboard. The AMT generates maximum speed, drive and hold through big carves to perform around pointbreaks or lined up beach breaks. The AMT’s honeycomb material give this fin a medium flex pattern while the large area provides ample hold in powerful waves. The AMT includes a small trailer for additional stability and performance.

A lightweight hexagonal core gives these fins the feel of glass-ons. Engineered with a medium flex pattern, these are stiffer than Blackstix but more flexible than Fiberglass.
Flat foiled fins break free sooner, and are better at controlling speed. Often surfers prefer them in fast powerful surf where they do not need to create additional speed. If you have muscle memory from riding glass-ons, flat foiled fins will feel the closest.
