2026 Naish Siren Semi-Complete Foil

2026 Naish Siren Semi-Complete Foil

Freestyle, Waves, & All-Around Mid-Aspect Foiling

Sizes: 600, 800, 1000, 1200, 1400 (cm²)

When you need total control in critical situations, the 2026 Naish Siren Semi-Complete Foil delivers steady, responsive performance across a wide range of water conditions. You'll notice early lift and low stall speeds thanks to its high-camber section, helping you stay up on foil even in lighter power or slow maneuvers. The swept leading edge maintains clean tracking so you feel composed when turning hard or driving through speed. Built with the rigid Alpha connection system, this setup gives you direct feedback underfoot whether you're carving waves or practicing freestyle tricks.

What Naish has to say:

The Siren is Naish’s new mid-aspect. Designed for control in critical situations, the Siren features a medium-aspect outline (8.2 - 8.5 AR), a high-camber foil section, and strong sweep in the leading edge. These features boost maneuverability, lower the stall speed, and provide exceptional stability to a foil that excels in disciplines which demand stability and maneuverability.

The smaller sizes are geared toward riders looking to push the limits in freestyle and waves, while the larger sizes focus on stability and low-end performance for intermediate riders to progress with confidence.

To maximize these characteristics, pair the Siren with an S-Series stabilizer. However, if you would like to achieve more efficiency, the E-Series stabilizer is a better choice. Utilizing our new Alpha connection system, the Siren receives a 30% increase in connection stiffness over our previous Legacy system. Featuring a larger cross sectional area, two or three M8 bolt connection depending on size, and a sleeker profile, the + connection system offers a more direct feel than ever.

Who is this for?

The Siren is designed for riders who prioritize control and maneuverability. The smaller sizes (600 and 800) target intermediate to advanced riders pushing their limits in freestyle, wave riding, and prone foiling. The larger sizes (1000, 1200, and 1400) offer lower-end lift and stability for intermediate riders looking to build confidence and progress smoothly.

Design Profile:

Medium-aspect outline (8.2 to 8.5 AR) with a high-camber foil section, swept leading edge, and thin profile for drag reduction.

Performance Features:

• Mid-aspect outline (8.2 - 8.5 AR) offers a balance of stability, glide, and tight maneuverability.
• High-camber foil section generates low-speed lift and reduces stall speed for stable low-end support.
• Swept leading edge maintains smooth tracking and control when building speed and banking turns under load.
• Alpha connection system increases stiffness by 30% compared to the Legacy connection system.
• Thinner section profile reduces drag to assist with acceleration and maintain efficient glide.

How does it compare?

Versus the Naish Legacy Connection System:

The Siren features Naish's Alpha connection system, delivering a 30% increase in connection stiffness over the previous Legacy setup. Designed with a larger cross-sectional area, a sleeker profile, and two to three M8 bolt connections depending on size, the Alpha system gives you a noticeably more direct response from board to foil.

Design Features:

• Mid-Aspect Outline - Aspect ratio of 8.2 to 8.5 combines predictable stability with responsive turning and glide.
• High-Camber Section - Provides strong early lift at lower speeds so you stay up on foil without stalling early.
• High-Sweep Leading Edge - Keeps the wing tracking predictably and smoothly through hard carves and speed buildup.
• Alpha Connection System - Increases overall connection stiffness by 30% using M8 hardware for increased control.
• Thinner Profile - Reduces hydrodynamic drag for faster acceleration and sustained cruising efficiency.
