A mid-length surfboard sits in the sweet spot between a shortboard and a longboard, typically between 6'8" and 7'8", and offers a fundamentally different feel than either. Longer rails create more glide through flat sections. More foam under the chest makes paddling easier. Refined outlines preserve maneuverability where traditional longboards would feel locked in. The result is a board that turns small waves into long, drawn-out rides and turns average waves into the kind of session that reminds you why you started surfing in the first place.

Mid-lengths draw lines other shapes can't take long, flowing, stylish trim that connects sections of the wave most shortboards miss. They reward smooth surfing over aggressive surfing, and they let you spend more time on the wave.

The Slot Machine is a single-slot-channel twin fin that scales from shortboard dimensions all the way to full mid-length, giving surfers a versatile platform that works across a range of sizes and conditions. The Twin Royale is the most stylish mid-length twin fin Doc has ever shaped. A deluxe wide-template cruiser with optional wood-grained keel fins, built for surfers who want their board to look as good as it rides.

What makes a great mid-length

The best mid-lengths share a few specific design traits that separate them from both shortboards and longboards. Longer rails — typically 6'8" or longer — give the board more contact with the wave, which translates to more glide and a smoother ride through flat sections. More foam distributed evenly through the board makes paddling easy and allows you to catch waves earlier without committing to longboard volume. Refined outlines and rocker keep the board responsive. A great mid-length doesn't feel like a downsized longboard, it feels like its own thing. Versatile tail shapes (swallows, pins, and rounded pins) keep the board engaging through turns without sacrificing the glide that makes mid-lengths special in the first place.

What separates a great mid-length from a mediocre one is feel. The best mid-lengths feel alive under your feet, they trim, they pivot, they hold their line. They make average surf feel meaningful in a way that pure performance boards can't.

How to choose the right mid-length

Mid-lengths reward choosing based on the kind of surfing you want to do, not just your skill level.
