Unifoil Nimitz Downwind Board

The Unifoil Nimitz Downwind Board is a dedicated prone-paddle foilboard built by Unifoil, a Hawaii-based hydrofoil brand known for its integrated foil systems. Designed around a displacement hull, the Nimitz targets riders who want efficient paddling speed to get on foil during open-ocean downwind runs while retaining a responsive, surf-oriented feel once airborne. Unifoil positions the board as a versatile platform suited to downwind foiling, SUP surf foiling, and even light- to high-wind winging sessions. It ships in three sizes — 100 L, 113 L, and 123 L — each paired with a board bag from Unifoil.

The hull shape is engineered around two priorities: low-drag forward glide during the paddle phase and minimal board contact once the foil lifts. Unifoil emphasizes the board's light swing weight, which contributes to quicker directional changes and more dynamic carving while riding swell on foil. The overall shape favors fast pop-ups and reactive pumping, keeping transitions from paddle stroke to foil flight as short as possible.

• Available sizes: 100 L, 113 L, 123 L
• 100 L dimensions: 7'5" x 18.5" x 5.75"
• 113 L dimensions: 7'7" x 19.5" x 6"
• 123 L dimensions: 7'10" x 20.5" x 6"
• Intended disciplines: Downwind foiling, SUP surf foiling, winging
• Included: Board bag

The Nimitz suits intermediate to advanced downwind foilers who already have a handle on prone takeoffs and want a board that rewards efficient paddling technique with quick lift-off. The three-size spread covers a range of rider weights and comfort levels — the 123 L offers more stability and paddle speed for heavier riders or those still building confidence in open-water starts, while the 100 L trims volume for lighter or more experienced riders who prioritize maneuverability once on foil.

Because Unifoil markets the Nimitz for SUP surf foiling and winging alongside downwind use, it can serve as a quiver-consolidating option for riders who foil across multiple disciplines and want one board that paddles well but doesn't feel sluggish in flight. Riders focused purely on high-performance prone surf foiling on small waves may find specialized surf foilboards more suited to tight pocket riding, but for open-ocean bump running the Nimitz's displacement hull and length give it a clear advantage in glide.

The Nimitz is Unifoil's primary dedicated downwind foilboard and sits within their broader ecosystem of foils, masts, and boards. Unifoil pairs it with their own front wings — the Progression series for newer downwind riders and the higher-aspect Hyper and Evolution lines for experienced riders chasing glide and efficiency. All components share Unifoil's proprietary connection system, so the Nimitz is built to integrate directly with their foil hardware.

In the wider market, the Nimitz competes with boards like the Armstrong Downwind Mk III, which offers a similar displacement-hull concept in five sizes ranging from 95 L to 135 L. The Armstrong board leans into a shorter, narrower outline for quicker turning, while the Nimitz prioritizes a surfy, responsive ride character. Riders choosing between the two will likely weigh foil-brand loyalty and local dealer availability alongside hull feel preferences.
