The Simon Anderson 5-fin setup was designed by the inventor of the thruster for the larger surfer looking for big-board performance. The honeycomb material combined with the flat foil offers a stiffer flex pattern ideal to hold powerful carves while the Simon Anderson 5-fin offers full templates for both thruster and quad options, making this fin ideal for the bigger surfer or a board with a wide tail.

FLAT Foil
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.
