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

The Greg Liddle-inspired single fin for hull and mid-length boards, in the most neutral and versatile grey in the catalog

Grey on a surfboard fin is the choice for the surfer who wants the fin to visually disappear into the tail of the board, only to be noticed when it's in the water doing what it's supposed to do. The Deflow Midhull 8.5" Grey carries the specific template for hull-type boards and mid-lengths in the most discreet and versatile colorway in the family: a grey that matches any board, never goes out of style, and possesses that mineral quality in the fiberglass lamination that we associate with high-quality materials and true durability.

WHY THIS FIN MAKES THE DIFFERENCE

The Midhull Grey is technically identical to the Blue and the Ochre, but visually, it is the most universal and least restrictive choice of the four:

• The Liddle template for flowing surfing — 125.5 mm narrow base and 215.9 mm height: the proportions of a fin designed to generate drive without locking in, to follow the rail through turns without slowing the board down or dictating a line. The controlled, fluid surfing Greg Liddle had in mind when he designed the first hull fins.
• Calibrated push and release — The Midhull's low flex provides the right balance between push and release. Enough push to provide drive during trim and at the start of a turn; enough release so the fin exits without resistance. The feeling of a fin that works with the surfer instead of creating obstacles.
• Long points: the Midhull's natural habitat — Those waves with a soft slope and long sections where you can travel from one end of the peak to the other with fluid, linked turns. On that type of wave, the Midhull is like a good bow that responds to the surfer's arc: smooth, precise, with no apparent effort.
• For gliders: endless glide — Gliders are the boards where the Midhull reaches its purest expression: that feeling of eternal glide, without friction, without resistance, where the board and the wave seem like one single thing. The Midhull Grey on a glider is exactly what the template's name promises.
• Grey: the grey that works in all contexts — Grey in fiberglass lamination has a neutral visual quality that doesn't compete with any board design. On white, natural, dark, and colored boards: the Midhull's Grey always adds value without distraction.

OUR EXPERTS' TIP

The Midhull's Grey is the perfect choice if you have several hull or mid-length boards with very different resin designs and want a single fin that works visually on all of them. That neutral grey disappears on any board in the most positive sense: it doesn't compete with anything; it complements everything. And from a technical point of view, the Midhull is simply the right fin for this type of board—a fin designed specifically for the bottom geometry that differentiates modern hulls and mid-lengths from any other type of surfboard.

DEFLOW WARRANTY — «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 in 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.

Deflow's Midhull is the model that most directly translates Greg Liddle's philosophy to the brand's contemporary catalog. It is not a copy of the original: it is an interpretation using quality fiberglass and a modern flex of the spirit Liddle distilled into his hull fins—that balance between push and release that makes surfing these boards feel the way it should.

The Midhull can also be used with side bites when the surf or conditions require it.

USAGE AND CARE

• Installation — Standard single fin box. Adjust the position based on the board type and style.
• Side bites — Compatible with side bites for greater control. Deflow has a set designed for this fin.
• Fiberglass care — Inspect regularly. Repair any dings with compatible resin.
• Storage — Away from direct heat, without lateral load.
