Armstrong Midlength FG Foilboard

The Armstrong Midlength FG Foilboard is a crossover design from Armstrong Foils that blends the glide characteristics of a downwind foilboard with the compactness and responsiveness of a traditional midlength surfboard. Built to serve wing foiling, prone surf foiling, and even foil-drive setups, the Midlength FG sits in a unique position within Armstrong's board lineup — longer and narrower than a dedicated wing board, but shorter and more maneuverable than a full downwind shape. The board is available in seven sizes from 38 to 100 liters, covering a wide span of rider weights and skill levels.

Armstrong's Forward Geometry (FG) design places the foil track position more centrally under the board, which reduces swing weight during turns and aims to deliver a more connected feel once on foil. The shape features a pointed but smooth nose profile, a gently tapering midsection, and a pulled-in tail with a diamond-V bottom contour. Full-length chines along the rails and a subtle double-concave-to-flat bottom at the foil tracks round out the hull design.

• Available sizes: 38L, 45L, 55L, 65L, 75L, 85L, 100L
• Dimensions (smallest): 4'9" x 17" x 3.5" at 38L
• Dimensions (largest): 6'9" x 22" x 5" at 100L
• Weight range: 3.2–3.8 kg (38L) to 6.2–6.65 kg (100L)
• Construction: Double-skin carbon PVC sandwich with i-beam dual carbon stringers
• Foil tracks: Proprietary forged carbon, keyed into stringer fibers
• Deck: Micro-textured pad with micro-cutouts, full-width kick pad, foil-track indicators
• Strap inserts: Y-configuration with three positioning options

The Midlength FG targets three overlapping rider profiles. Wing foilers looking for improved light-wind performance will benefit from the board's efficient paddling glide and quick release onto foil — it gets airborne with noticeably less effort than a conventional compact wing board. Prone surf foilers who want early wave entry in small or marginal conditions will find the elongated outline and narrow width effective for generating paddle speed. And riders searching for a single versatile travel board can use the Midlength across disciplines without carrying multiple shapes.

Skill level ranges from progressing intermediate to advanced. Riders stepping down in volume as their skills develop will appreciate that the board derives stability primarily from its length rather than its width, so it feels secure underfoot once moving forward despite its relatively narrow profile. The narrower outline also means it rarely catches water during aggressive transitions or sharp directional changes, rewarding confident riders who push the board through tight turns.

Within Armstrong's own range, the Midlength FG sits between the dedicated Wing boards and the longer Downwind shapes. It borrows hull-design cues from the Downwind line — particularly the emphasis on paddle-powered glide — while staying short enough to handle like a surf-oriented platform once on foil. Armstrong also offers purpose-built Prone foilboards for riders who want a shape optimized purely for wave catching.

The crossover midlength category has grown across several brands. Comparable designs include boards from KT Surfing and Sunova that similarly stretch the outline for improved glide while keeping volume moderate. Armstrong differentiates with the FG foil-track placement and its forged carbon track system integrated directly into the stringer structure, which contributes to the board's relatively low weight across the size range.
