The M4 Twin is a twin-fin with forward drive and a smooth feel — a reliable everyday board with just enough edge to push when the wave allows. The wide point is set 4” forward for early entry and flow, paired with a rolled deck and lower rails that blend into a sharp edge through the tail.
Underneath, it runs a subtle single to double concave with vee and four short channels between the fins. These channels add a touch of bite and acceleration without stiffening the board up — it still flows rail to rail, but gives you that extra squirt when you lean into it.
The pin tail keeps it smooth and controlled, especially when the waves have a bit of push. It’s a great option for surfers chasing a twin that paddles well, holds when you’re on rail, and still releases clean when the section opens up.
