The ST (Square Top) Turbo Fins are longer and stiffer than the standard MirageDrive fins and will deliver a speed boost as well as more torque. ST Turbo fins are especially valuable when adding a sail kit, as the added surface area and stiffness of the ST Turbo Fins are more effective whenever tacking or sailing up-wind. Users who prefer a slower cadence will especially appreciate the ST Turbo Fins. Turbo fin kits include fins, masts & fitting hardware and small tube of loctite.
