The Al Merrick Twin 1 (AMT) was designed by Channel Islands creator 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 construction gives this fin a medium flex pattern, while the large area provides ample hold in overhead surf. The set is equipped with the option to ride with a small trailer fin for increased drive and stability, creating more of a thruster feel.
