Surfboard Fins by Endorfins The Endorfins Machado Seaside Quad Fin set is a versatile system designed by Rob Machado that works beautifully across any quad surfboard shape. This updated version is developed with a twin keel starting point to deliver the drivey, basey feeling of a keel fin set combined with exceptional carving characteristics. The re-engineered design features raked back front fins and upright trailers that allow you to pivot more tightly while maintaining excellent hold. Entirely built to be 15% lighter than previous versions, this set offers a larger sweet spot that gives surfers the freedom to position their back foot for either drawn out carves or quick releases. • Rob Machado designed quad fin set for his Seaside model • Most popular quad fin set that provides a drivey and basey feeling of a keel fin set • Works in any quad fin board shape • Single Tab variants are compatible with Futures fin system • Fin design began with the Go Fish model in 2016 and evolved in 2018 • Designed using a twin keel set as a starting point instead of a thruster set • New and updated version improved for balanced all around performance across various surfboard shapes • Front two fins are slightly more raked back compared to the original • Two quad trailers are slightly more upright compared to the original • Maintains carving characteristics while adding the ability to pivot more tightly and immediately • Larger sweet spot allows the surfer to position their back foot more freely on the tail • Offers both drawn out carving and a quick pivoting ability to slide or slip the fins free • Effective area on the front fins is moved towards the back with more sweep or rake in the profile • Front fins have 2 degrees less cant, a slightly fuller foil, and are slightly stiffer than previous versions • Back fins have more curve, a fuller foil, and are slightly stiffer than previous versions • Entire set is 15% lighter than previous versions weighing 0.6 lbs per set
