Greenough 4A


Fins contribute hugely to how a surfboard performs, so we’ve selected some that suit our range of surfboards from two of the world’s best fin producers, True Ames and Rainbow Fin Co.

George Greenough has forged the path for many surfboard design elements and the fin is no exception. His classic 4A template is widely considered the benchmark of modern fin design and fits well in performance longboards or your favourite mid-length. It also offers itself well to a 2+1 fin setup.
