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 set is equipped with the option to ride with a small trailer fin for increased drive and stability through bottom and top turns.
