The M4 Twin (Mini 4 Channel Flow) is a twin-fin designed for smooth, forward-driving flow with reliable everyday performance and just enough edge to push when the wave allows. The wide point is positioned 4” forward for early entry and natural momentum, combined with a rolled deck that transitions into lower, medium rails sharpening through the tail for added sensitivity and control.
The bottom features a subtle single-to-double concave flowing into vee out the back, with four short channels between the fins — these deliver bite and acceleration for drive through turns, while keeping the board forgiving and fluid rail-to-rail. The pin tail provides smooth hold on rail and clean release off the top, especially in waves with power.
This handshaped example measures 6'6" x 20 3/8" x 2 5/8" (approx. 37.1L), offering excellent paddle power and easy glide without sacrificing responsiveness.
