Armstrong Wing FG Foilboard - 70L-135L

The Armstrong Wing FG Foilboard is a dedicated wing foiling board from Armstrong Foils, built around the brand's Forward Geometry (FG) platform. The FG concept places the foil mounting tracks further forward toward the center of the board, which reduces swing weight during turns and increases responsiveness on the foil. Armstrong offers the Wing FG across ten sizes spanning 34 L to 135 L; the six sizes in this grouping — 70 L through 135 L — cover the mid-to-high volume end of the range, suiting heavier riders or those who want extra float for easier water starts.

The board's outline is narrower than a typical high-volume wing board, a deliberate choice that improves planing speed, reduces windage when overpowered, and sharpens turning response once foiling. A swept wedge nose balances water displacement with forward glide, while the deck features a wider, flatter standing area with contoured grip-pad edges and gentle reference humps to help riders find optimal foot placement by feel.

The 70 L–135 L size range targets a broad rider spectrum. Larger volumes (120 L and 135 L) give newer wing foilers the buoyancy they need for stable water starts and unhurried transitions onto the foil, while the 70 L and 80 L sizes suit intermediate-to-advanced riders who want a compact platform with enough volume for comfortable uphauling in lighter wind. Armstrong positions the Wing FG as a board that supports progression from first flights through to competition-level riding.

The narrower outline and toned-down hull concaves promote an early release from the water surface, meaning less power is required to get foiling. This can let riders step down to a smaller wing in marginal conditions. A 90 kg rider, for example, has been tested comfortably on the 80 L size with the foil mounted near the center of the track — no shims needed — highlighting the board's balance between stability and maneuverability at moderate-to-heavy rider weights.

Within Armstrong's current catalog the Wing FG sits alongside the smaller Wing FG sizes (34 L–58 L) aimed at lighter or more advanced riders chasing a sinker-style experience. Armstrong also offers a Wing Surf FG board shaped for wave-oriented foiling, giving buyers a clear choice between flat-water / freeride use (Wing FG) and downwind or wave-face riding (Wing Surf FG).

The current Wing FG is the evolved second generation of the design, refining the outline and hull shape from the original model. Comparable boards from other brands include the F-One Rocket Wing V3 and the Fanatic Sky Wing, both of which occupy a similar all-round wing foiling niche, though the Armstrong's extended FG track system and universal foil compatibility remain distinctive features in this segment.
