About this fin

( 2 Fin Set ) FCS Compatible: These low-profile keels featuring a large amount of rake were carefully developed by Mick Mackie - a true connoisseur of twin fins and fishy type craft who has been honing his skills in this realm over the last two decades. The swept-back profile and minimal depth of these fins will translate to fast and smooth surfing with heaps of drive and down-the-line projection. These fins will pair well with fishes as well as other wide tailed boards that love a long drawn out wall or point break style surf. HEIGHT: 4.715" / 120mm BASE: 8.00" / 203 mm AREA: 23.47”² / 151.39 cm²
