Armstrong Midlength FG Foilboard

The Armstrong Midlength FG Foilboard blends the glide characteristics of a downwind shape with the maneuverability of a traditional surfboard outline. Produced by New Zealand-based Armstrong Foils, the Midlength FG is a multi-discipline foilboard built for prone surf foiling, wing foiling, and general foil progression. The board draws on downwind-inspired bottom contours — a subtle double concave flowing to flat through the foil-track zone, a diamond-V tail, and full-length chines — while keeping a surfboard-inspired outline that paddles efficiently and launches onto foil with less effort than a conventional compact board. Armstrong positions it as a versatile option that bridges the gap between dedicated prone, wing, and downwind foilboards.

• Construction: Double-skin carbon PVC sandwich with i-beam top-to-bottom dual stringers
• Foil tracks: Proprietary carbon-fiber tracks keyed into the stringer fibers
• Foil compatibility: Universal — designed to work with any brand of foil
• Deck grip: Micro-cutout traction through the main standing area; full-width kick pad at the rear with foil-track location indicators
• Footstrap inserts: Optional, pre-installed
• Available sizes: 38 L (4'9"), 45 L (5'1"), 55 L (5'5"), 65 L (5'9"), 75 L (6'1"), 85 L (6'5"), 100 L (6'9")
• Weight (38 L): 3.2–3.8 kg

The Midlength FG suits riders looking for a single board that works across multiple foiling disciplines rather than maintaining separate quiver slots for prone surf, wing, and light-wind sessions. Its length-derived stability makes it accessible to intermediate foilers progressing from larger, wider boards, while the narrower outline and centrally placed foil tracks keep it responsive enough for experienced riders who want quick rail-to-rail transitions. Armstrong describes it as a session saver on small or light days — a board that paddles into waves earlier and gets on foil faster than a standard compact shape.

In wing foiling, the extra waterline length and glide help riders get airborne in lighter winds, roughly matching a downwind board's launch capability in typical 10–15 knot conditions while remaining far more maneuverable once on foil. Prone surf foilers benefit from faster paddle speed and earlier wave engagement compared to shorter, wider alternatives. The seven-size range — from a 38-liter performance shape up to a 100-liter platform — lets riders match volume to body weight and skill level without compromising the core design intent.

Within Armstrong's board range, the Midlength FG sits between their compact foilboards (shorter, wider shapes tuned for dedicated prone or wing use) and their full downwind boards (longer, narrower glide machines built for open-ocean runs). The FG in the name refers to the centrally positioned foil-track geometry, which Armstrong says reduces swing weight in turns compared to a standard rear-mounted track layout. The line originally launched in five sizes (45 L through 85 L) and later expanded to the current seven-size spread, adding the smaller 38 L and larger 100 L to cover a wider rider-weight spectrum.

Buyers cross-shopping multi-discipline foilboards may compare the Midlength FG against shapes like the Sunova Downwinder or the KT Surfing Drifter, both of which target similar crossover territory between prone, wing, and downwind foiling. The Armstrong's universal foil compatibility and integrated carbon-track construction distinguish it as a brand-agnostic option — riders are not locked into a single foil ecosystem.
