Designed as a TWINZER+ setup, this fin package takes the familiar Twinzer layout and adds a rear stabilizer trailing fin for extra punch, power, and hold. The result is a fin set that blends the fast, lively character of a twin with the added drive and control many surfers want in more performance-focused boards.\u003c\/p\u003e\r\n\r\n  \u003cp\u003eLike traditional Twinzer setups, the forward canard fins are designed to extend the base, claw into the wave face, and apply added pressure through the bottom of the board. Because of that added engagement, the main twin fins use a more upright outline with a narrower base and lower area, inspired by the fast-reacting “snip-tip” twins that have become increasingly popular. The canards are shaped to complement that flow, using a matching tip template and a trailing edge that parallels the leading edge of the main twin for a smooth, coordinated feel through turns.\u003c\/p\u003e\r\n\r\n  \u003cp\u003eThe rear trailer uses the same Futures mini box as the canards and features a forgiving outline that releases cleanly when pushed. Built in fiberglass for a classic, dependable flex feel, the Futures Mayhem Twinzer Medium set creates a strong fin-to-board connection using a combination of Futures ILT and Twinzer box technology while keeping the tail feeling light and balanced.
