Sabfoil Flat 370 Rear Stabilizer Pro Finish | Hydrofoil Stabilizer

The Sabfoil Flat 370 Rear Stabiliser is built around manoeuvrability. Part of the Sabfoil hydrofoil system, its flat profile and winglet-free outline keep the tail loose and playful, letting you pivot, carve and throw the foil around with minimal resistance — a favourite for surf-style and freeride riding where a free-feeling tail matters more than locked-in tracking.

With a 195cm² surface and a moderate 7.00 aspect ratio, the Flat 370 sits mid-range — enough area to add lift and stability to smaller, faster front wings, while the flat section keeps turning quick and intuitive. It's a versatile match for wing, kite and surf foiling setups.

Who It's For

• Discipline: Surf foiling, freeride wing and kite foiling on smaller, faster front wings
• Level: Intermediate to advanced foilers who prioritise a loose, playful tail over locked-in tracking
• Best for: Riders pairing it with a smaller, faster front wing where turning quickness matters more than maximum stability

Key Features

• 195cm² surface area – mid-range size adding useful lift and stability to smaller, faster wings
• 7.00 aspect ratio – moderate profile keeping turning quick and intuitive
• Winglet-free flat profile – keeps the tail loose and playful for pivoting and carving
• Full carbon with core construction – around 121g, durable and consistent under load
• SAB Pro Finish – hand-sanded matte surface with 0-thickness graphics, Made in Italy

Real-World Feel

The Flat 370 feels genuinely loose underfoot — it pivots and carves with minimal resistance, letting you throw the foil into turns rather than working against it. That playfulness is exactly what surf-style riders want, where a free-feeling tail lets you commit to sharper, more dynamic turns on a wave face. It still adds enough lift and stability to keep smaller, faster front wings settled at speed.

Setup / Fit

The Flat 370 mounts to your fuselage using Sabfoil's modular hardware — pair it with a Sabfoil front wing and fuselage to complete your hydrofoil. Not sure which stabiliser suits your wing? Speak to the team at Northern Watersports and we'll help you match it.

Pairs Well With

The Flat 370 works well with smaller, faster Sabfoil front wings for surf-style riding — check out our foil masts and fuselage options if you're building a full setup from scratch.

Why We Stock It

Surf-style foiling has different demands from freeride cruising, and a loose, playful tail makes a real difference when you're trying to commit to sharper turns on a wave. We stock the Flat 370 for exactly that reason — it's the stabiliser we recommend when manoeuvrability matters more than raw stability.

FAQs

What is the Sabfoil Flat 370 Rear Stabiliser?

It's a mid-range, 195cm² full-carbon-with-core stabiliser from Sabfoil's flat range, with a winglet-free profile that keeps the tail loose and manoeuvrable for surf-style and freeride riding.

What front wings does the Flat 370 suit?

It's best suited to smaller, faster Sabfoil front wings used for surf foiling, freeride wing foiling and kite foiling, where quick turning matters more than maximum stability.

Is the Flat 370 compatible with my Sabfoil fuselage?

Yes, it mounts using Sabfoil's modular fuselage system. Check whether your setup is T6 or T8 spec, as the mounting screws differ between the two.
