DEFLOW BULERÍA (FUGUE) 10.5" | LONGBOARD SINGLE FIN SIGNED BY CLOVIS DONIZETTI

Bulerías (Fugue): Clovis Donizetti’s longboard fin that understands everything

There are fins that do one thing well. And there are fins that understand what you want before you even decide. The Deflow Bulerías (Fugue) 10.5" is one of the latter. Signed by Clovis Donizetti—one of the most elegant and thoughtful longboarders on the European scene—this fin was born from years of modifying the curves of three iconic models he grew up with, much like a musician rewrites a jazz standard or a folk song until it becomes their own. The result is a fiberglass single fin that works when you surf smoothly, when you trim the wave in silence, when you do nothing, and also when you push hard and execute every maneuver possible.

WHY THIS FIN MAKES THE DIFFERENCE

A 10.5" longboard fin is not just an accessory—it is the board's character. It changes the feel of the turn, the response to the trim, the ease of noseriding, and the way the board connects with the water. The Bulerías has been designed by someone who has spent decades understanding exactly those differences and choosing each curve with intent.

• Designed by Clovis Donizetti — This is not a catalog fin. It is Clovis’s personal version of three iconic models that he spent years refining, adapting to his surfing and the waves he regularly rides. A fin with its own story.
• 10.5" height — total presence — With a height of 266.7 mm and a base of 220 mm, the Bulerías is the ideal size for longboards between 9' and 10'+ where you are looking for traction, control, and a full-rail feel.
• Fiberglass with controlled flex — The exact combination for classic longboarding: enough stiffness to transmit the energy of the wave in every trim, with just the right amount of flex so that turns are fluid and not mechanical.
• Total versatility — Surf light or push hard. Trim in silence or execute maneuvers. This fin doesn't force you to choose a style—it adapts to whatever the wave and the moment demand.
• US Box system — The universal standard for longboard single fins. Direct installation, adjustable positioning.
• Deflow Signature Collection — Part of Deflow’s most personal collaboration line, where each fin has its own voice and a surfer behind it with something real to say.

EXPERT ADVICE

The 10.5" Bulerías is a fin for longboarders with a discerning eye. Its size and controlled flex make the board respond with precision—ideal for someone who already knows what they want from a single fin and is looking for a fin with its own character. If you surf mainly in soft waves or on mid-lengths, the Seguiriya (10") model may be a more versatile starting point. But if your surfing lives on longboards over 9' and you want a fin that handles both measured trim and more demanding maneuvers, the Bulerías is the choice. Position the fin slightly forward if you want more freedom in turns; further back if you want more traction and control in noseriding.

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

Deflow was born in Zarautz, in the heart of Basque surfing, founded by a group of surfers with a clear mission: to manufacture fins with the best materials and without compromising on quality. Their Signature collection is the space where that philosophy becomes most personal: collaborations with surfers who not only love surfing, but who feel responsible for its history and cultural impact.

Clovis Donizetti is one of those surfers. With a vision of surfing that goes beyond performance—one that speaks of culture, respect, and legacy—and a style on the board that Deflow describes as jazz: the perfect notes at the perfect time, mastery of rhythm with space for improvisation, without unnecessary adornment. The Bulerías (Fugue) carries that vision etched into every curve.

USE AND CARE

• Installation — Insert the fin into the US Box and adjust the position according to your surfing preferences. Tighten the screw with the appropriate key. Do not overtighten.
• Positioning — On a classic longboard, the usual starting point is with the base of the fin centered in the box. Adjust forward for more fluidity in turns; backward for more traction and noseriding.
• Cleaning — Rinse with fresh water after each session. Dry the base before storing to prevent oxidation of the box screw.
• Storage — Store the fin outside the board during prolonged periods of non-use. Avoid direct sun exposure.
• Inspection — Periodically inspect the fiberglass lamination. Remove the fin from use if any cracks or chips appear.

SIZE GUIDE

As a general reference, a 10.5" fin works best on longboards of 9 feet or more where maximum traction, noseriding control, and rail presence are sought. For shorter boards or mid-lengths, consider the Seguiriya (10") version from the same collection.
