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

The Greg Liddle-inspired single fin that makes hull boards and mid-lengths flow as they should, in the most natural, oceanic blue in our catalog

There are colors that belong to the sea long before they reach it. The blue of the Deflow 8.5" Midhull Blue is one of them: a medium-dark blue with the depth of the Atlantic on a clear day, which in the fiberglass laminate has that visual quality that connects directly with the environment where this fin is meant to be surfed. For the surfer who owns a hull, mid-length, or glider and is looking for the fin Greg Liddle would have designed for that type of board, in the color that best reflects how that surf should feel.

WHY THIS FIN MAKES THE DIFFERENCE

The Midhull has a template completely different from any other fin in the Deflow catalog. It doesn't come from the same family as the Cream: it is a fin specifically designed for the geometry of hull-type boards and for the type of surfing those boards demand:

• Inspired by Greg Liddle: the right source — Greg Liddle is the designer who took the hull-type surfboard to its maximum expression, and his slender single fins with significant rake and a narrow base are the benchmark for any serious fin for this type of board. The Deflow Midhull takes that reference and adapts it with modern fiberglass and a flex calibrated for the contemporary surfer.
• Push and release in the turn — The Midhull's character in the turn is different from a conventional fin. The push gives the board traction to enter the turn with energy; the release allows it to exit with fluidity and no resistance. Smooth rail transitions, without the "locking" feeling caused by fins with too much base or too much area.
• The type of wave where this fin shines — Long point breaks with soft waves are the Midhull's natural habitat. Those waves where you can make wide, fluid turns, link maneuvers without interruption, and go from the right to the left of the peak with a constant feeling of speed and control.
• Mid-length 7'-8': the board that makes the best use of this fin — Modern mid-lengths in the 7' to 8' range have the length and volume for the Midhull to generate the right balance between drive and maneuverability. It can work on shorter or longer boards, but this is the range for which the design is calibrated.
• Blue: the blue that's in its element — That deep, natural blue in the Midhull's fiberglass laminate has the exact visual presence this type of fin needs: discreet from a distance, with character when you look at it up close. The color that looks like it should have always been in your board's fin box.

EXPERT ADVICE

The Blue Midhull is the most natural colorway for this type of fin: that deep blue has a visual presence in the water that fits perfectly with the type of surf it's designed for. It works on any board, but it looks especially beautiful on hulls and mid-lengths with white or cream-toned resins, where the blue of the fin provides a clean, elegant contrast. If you have a modern mid-length and have been surfing it with generic fins without finding the character you expect from that board, the Midhull Blue is likely the answer you’ve been looking for.

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 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.

The Midhull is the Deflow model that most directly pays tribute to a specific designer: Greg Liddle, the master of hulls and slender single fins that forever changed the understanding of surfing on concave-bottom boards. Deflow's version adapts that philosophy for the contemporary surfer with quality fiberglass and a flex calibrated for modern use.

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