Description
The Stabiliser Range That Matches the AFS Silk System
The AFS Silk Stabiliser is the rear wing developed in harmony with the AFS Silk front wing range — arguably AFS's most refined and versatile foil system, spanning everything from surf foiling and wave riding to downwind and light wind wing foiling. The Silk Stab range covers seven variants: three standard-aspect options (132, 142, and 152 cm²) for carving and wave riding, and four high-aspect options (HA38, HA40, HA43, and HA165) for maximum glide and pumping efficiency.
Whatever you're doing on your Silk setup, there's a matched rear wing from AFS's AFS foils range to complement it.
Who It's For
The Silk Stabiliser suits wing foilers, surf foilers, and downwind foilers riding the AFS Silk or AFS Enduro front wings who want a rear wing dialled into that system. The standard 132/142/152 range is for riders prioritising wave riding, carving, and medium-to-high speed performance. The HA38/HA40/HA43 range is for those pushing into downwind foiling, pumping, and light wind efficiency. The HA165 is the largest high-aspect variant, offering the most lift area in the HA range for heavier riders or larger front wing pairings.
Key Features
- Seven variants: 132 / 142 / 152 cm² (standard) and HA38 / HA40 / HA43 / HA165 (high-aspect)
- Silk 132: 132 cm² surface area, 300 mm span — tightest, loosest, most pivoty
- Silk 142: 142 cm² surface area, 320 mm span — versatile all-round surf/freeride option
- Silk 152: 152 cm² surface area, 340 mm span — more lift and support, confidence in varied surf
- HA38/HA40/HA43: high-aspect profile, span in cm (380/400/430 mm) — glide, pumping, downwind
- HA165: high-aspect, ~165 cm² surface area — maximum lift in the HA range
- Standard stabs: compact outline and pronounced dihedral for fast rail-to-rail transitions
- HA stabs: thin profile and elongated span for low drag and pumping efficiency
- UHM carbon construction throughout — light, stiff, responsive
- AFS Fuselink compatible — fits all current AFS fuselages
- Supplied with screws and protective cover
- 100% made in France
On the Foil
The standard Silk 132, 142, and 152 share the same DNA as the compact surf stabs in the AFS range — pronounced dihedral, tight outline, bumps on the leading edge that add control mid-carve. The result is a stabiliser that transitions from rail to rail quickly, provides satisfying lift during the carve, and holds your height when you change support angle abruptly. They're surf-oriented but not narrow in application: these stabs feel at home in small onshore waves as much as they do in clean groundswell.
The HA38, HA40, and HA43 are a completely different tool. The naming refers to span in centimetres — 380, 400, and 430 mm respectively. These are high-aspect stabs with a thin profile and elongated span, and they express their full potential at low-to-medium speeds where pumping efficiency counts most. They make it easier to relaunch after a jibe, carry further between wave sets, and cover ground in a downwind run without burning your legs. The HA165 offers the most surface area in the HA line and suits heavier riders or setups where more rear wing lift is needed.
Compatibility and Setup
All Silk Stabiliser variants connect via the AFS Fuselink system — two M6 screws, any current AFS Fuselink or EVO fuselage. The Silk Stab range is developed for the Silk front wing range (700–1000 cm²) and also pairs well with the Enduro range. The HA stabs additionally pair with the Ultra HA front wing range and U Glide setups. Pre-2023 Alpha and Performer mast users need the 2024 AFS Switch Fuselage.
Construction
The Silk Stabiliser range is built in UHM (Ultra High Modulus) carbon at AFS's facility in France. The standard stabs use a compact layup optimised for stiffness and rail-to-rail response. The HA stabs use a higher-modulus layup across the span to resist flex at the tips — critical at high aspect ratios where any tip flex degrades the hydrodynamic efficiency the design depends on.
Size Guide
| Variant | Type | Area / Span | Best For |
|---|---|---|---|
| Silk 132 | Standard | 132 cm² / 300 mm | Advanced surf/wave foilers, tightest carve, maximum pivot |
| Silk 142 | Standard | 142 cm² / 320 mm | Best all-round standard stab — surf, wing foiling, freeride |
| Silk 152 | Standard | 152 cm² / 340 mm | More support and confidence, varied surf, heavier riders |
| Silk HA38 | High-aspect | 380 mm span | Lighter riders, pumping and downwind, high-aspect setups |
| Silk HA40 | High-aspect | 400 mm span | Most riders — best all-round HA option for Silk/Enduro systems |
| Silk HA43 | High-aspect | 430 mm span | Heavier riders, larger HA front wings, maximum pumping carry |
| Silk HA165 | High-aspect | ~165 cm² | Maximum HA lift area — heavier riders, long-distance downwind |

Why We Stock It
The Silk front wing range is one of the most popular setups we sell, and the Silk Stabiliser is the rear wing that AFS designed to go with it — not an afterthought, but a matched component developed with the same care as the front wing itself. Having both the standard and HA variants available means you can run two different stabs with the same front wing and genuinely shift the character of the foil to suit conditions. That flexibility is hard to find at this price point.
FAQs
What do the standard Silk stab sizes mean — 132, 142, 152?
These numbers refer to the surface area of the rear wing in cm². The 132 has a 300 mm span, the 142 a 320 mm span, and the 152 a 340 mm span. More surface area = more lift, stability, and support through turns. Less area = tighter pivot, looser feel. The 142 is the most popular all-round starting point for most Silk front wing riders.
What do the HA stab sizes mean — HA38, HA40, HA43?
The HA numbers refer to the span (wingspan) of the stabiliser in centimetres — so HA38 is 380 mm, HA40 is 400 mm, and HA43 is 430 mm. This is a high-aspect range, so the naming convention is based on span rather than surface area. The HA40 is the most popular all-round choice; HA38 suits lighter riders and faster setups; HA43 suits heavier riders and larger front wings.
When should I use a standard Silk stab versus a Silk HA stab?
Use the standard 132/142/152 when your primary focus is wave riding, carving, and manoeuvring — these stabs are tuned for fast rail-to-rail transitions and surf feel. Use the HA38/HA40/HA43 when your goal is downwind foiling, pumping efficiency, light wind performance, or getting maximum carry between waves. Many riders own one of each and swap depending on conditions and session type.
Are the Silk stabs compatible with non-Silk AFS front wings?
Yes — all Silk Stabiliser variants fit any AFS Fuselink or EVO fuselage and are physically compatible with the full AFS range. The Silk stabs pair particularly well with the Enduro front wings as well as their native Silk range. The HA variants also work with the Ultra HA and U Glide setups. Compatibility extends across the entire current AFS Fuselink ecosystem.
Is the Silk HA165 the same type as HA38/40/43?
The HA165 shares the high-aspect character of the HA38/40/43 range but is specified by surface area (~165 cm²) rather than span. It offers the most lift area in the Silk HA range and is suited to heavier riders or long-distance downwind setups where maximum rear wing lift is an advantage. Think of it as the high-volume option in the HA range.
How do I choose between the Silk stab and the U Glide for a downwind setup?
The Silk HA stabs and the U Glide are both high-aspect rear wings built for glide and pumping efficiency. The Silk HA range was developed in the context of the Silk and Enduro front wing system, so it feels most natural with those front wings. The U Glide (UG39/41/43) has a slightly higher confirmed aspect ratio (13.7 for the UG41) and is also recommended for use with the Ultra HA range. If you're running Silk front wings, Silk HA stabs are the natural fit. If you're on the Ultra HA or want the absolute maximum aspect ratio in a stab, the U Glide is the tool.
