DEFLOW MIDHULL 8.5" | SINGLE FIN FOR HULL AND MID-LENGTH OCHRE

The Greg Liddle-inspired single fin that makes hull boards and mid-lengths flow as they should, in the warmest mineral ochre in our catalog

Greg Liddle is the shaper who has thought most deeply about what a fin does for a hull board. His designs for slender, long, high-sweep single fins defined a way of surfing where the fin doesn't steer, but rather accompanies: the surfer doesn't push, they flow. The Deflow Midhull 8.5" Ochre brings that philosophy to the Basque brand's catalog: a fin specifically designed for hull boards, 7' to 8' mid-lengths, and gliders, in the earthy, mineral yellow of ochre, which, in fiberglass lamination, possesses that natural warmth of pigments derived from the earth.

WHY THIS FIN MAKES A DIFFERENCE

The Midhull is neither a larger Cream nor a smaller pivot fin. It is a template with its own identity, designed for a type of surfing and a type of board that has its own rules:

• Specifically designed for hull boards — Hull-type boards have a concave bottom that generates speed differently than a conventional shortboard or longboard. The Midhull is engineered to work with that bottom geometry, not against it: its dimensions, sweep, and area distribution are calibrated to let the hull do what it does best.
• Push and release — The Midhull's design provides the necessary drive for the board to generate traction while trimming, and the release that allows the fin to exit fluidly during rail transitions and turns. No binding, no unnecessary drag. More flex than a conventional performance fin, less than the original Liddle designs: the perfect balance for modern surfing on classic boards.
• Ideal for long, soft point breaks — The character of the Midhull is best expressed on long waves with a gentle slope where the surfer can explore the length of the wave with wide, fluid turns. It is not a fin for aggressive vertical surfing: it is the fin for surfing that flows with the energy of the wave, not against it.
• 7' to 8' mid-lengths: the exact range — Modern mid-lengths are boards that demand a fin with more area than a shortboard and more character than a conventional longboard fin. The 8.5" Midhull is at the sweet spot of the spectrum for this type of board.
• Also for gliders — Gliders are the boards where the Midhull shows its most ethereal side: effortless, interference-free, with that sensation of endless glide that only fins designed for this type of surfing can provide.
• Ochre: the mineral ochre of the earth — The earthy, warm yellow of ochre is one of the oldest pigments in art history. In the Midhull’s fiberglass lamination, this tone has a natural depth that no saturated yellow can mimic. A fin that looks like it has always been there.

ADVICE FROM OUR EXPERTS

The Midhull is the fin we recommend when someone tells us they have a hull or mid-length and want it to feel how it's supposed to feel. The bottom geometry of these boards needs a fin that accompanies rather than blocks, and the Midhull is exactly that. If you come from surfing your mid-length with a 9" Cream or a conventional shortboard fin and it has never quite worked right, your board was very likely waiting for a fin like this. Ochre is the warmest and most natural colorway in the catalog: that mineral yellow looks especially good on boards with natural, earthy, or wood-toned resins.

DEFLOW GUARANTEE — "OUR LOVE FOR THE SEA BROUGHT US HERE"

Deflow was born on the beach of Zarautz, started by a group of surf enthusiasts with a clear obsession: to create efficient, beautiful, and honest fins. What began as a community of riders from the Basque Country has become a benchmark brand in the European market, recognized for its technical rigor and respect for the history of fin design.

The Midhull is the Deflow fin that pays tribute to Greg Liddle — the master of hull-type boards and slender single fins who changed the way people thought about surfing boards with concave bottoms. Deflow does not copy the original template: it interprets it with modern fiberglass, adjusting the flex to function in daily surfing without losing the character that makes it special.

The Midhull can also be used with side bites when the surf or conditions demand it. Deflow has designed side bites specifically to complement the performance of this fin.

USAGE AND CARE

• Installation — Standard single fin box. Adjust the position in the box according to the board type and style: hulls usually perform best with the fin in a neutral or slightly forward position.
• Side bites — The Midhull is compatible with side bites for greater control in more powerful conditions. Deflow has a set of side bites designed to complement this fin.
• Fiberglass care — Inspect regularly for dings or delamination. Repair any ding with compatible resin before continuing to surf.
• Storage — Keep away from direct heat and without side pressure that could compromise the flex.
