Hydroglass Quad Rear - FCSII

Our quad trailer fins are a primary option for all 5 plug boards. Their 50/50 foil gives control and facilitates turns whilst also giving speed in a variety of wave conditions from pumping to small waves. Available in FCSII and Single Tab.

Our HydroGlass fins are made with polyester resin and 34 layers of glass. This construction is great for generating speed and providing drive. The consistent flex allows for smooth rail-to-rail surfing during turns without losing speed.

Our HydroGlass fins are built in partnership with FCS and MFC Hawaii who have devoted more than 30 years now to creating the best fins possible, by innovating at every stage of construction. They tirelessly work towards the title of world's fastest fins, which makes them the perfect partner for the world's fastest surfboards. From our extensive range of boards including small wave fishes, high performance shortboards and big wave guns, to these fins, JS is always Built For Speed.
