Today, this new and updated version of my original quad set was improved to create more of a balanced and all-around performance characteristic across a variety of different surfboard shapes. The front two fins are slightly more raked back than the original, and the two quad trailers are slightly more upright than the original. I did this to maintain the same carving characteristics of the original quad set, while adding in a new ability to pivot more tightly and immediately than the original quad set. Overall this gives the new and updated quad set a bigger and better sweet spot, enabling the surfer to position their back foot more freely on the tail, without sacrificing either a drawn out carving ability, or a quick and pivoting ability to slide or slip the fins free when wanted, for a wider variety of maneuvering than the original quad set. The effective area on the front fins of the new Machado Seaside Quad set is moved towards the back of the fins with a little more sweep/rake in the profile in comparison to pervious versions. The front fins have 2 degrees less cant than the previous sets, a slightly fuller foil and are a slightly stiffer than previous versions. The back fin on the new Machado Seaside Quad have more curve, fuller foil and are slightly stiffer than previous versions.
