Severne Mach 9

The Severne Mach 9 is a slalom race sail developed to offer immediate acceleration, high top speed, and great profile stability. It is designed for experienced riders looking for a competitive sail that is precise in tuning and capable of maintaining constant drive even at high intensity.

Sail character

The Mach 9 is designed to convert power into real forward momentum, with a prompt response from the very first stages of loading. The feel is direct, fast, and performance-oriented, with a structure designed to support quick starts, continuous acceleration, and excellent control throughout the operating range.

Key features

Advanced acceleration and low end

The longer boom across the entire range moves the clew further outwards, increasing low end and acceleration. This allows for more effective thrust at the start and a more incisive behavior during relaunch.

Double clew adjustment

The double clew position allows the sail's character to be adapted to conditions and rider style. The outer position prioritizes maximum performance, drive, and constant power; the inner position makes the behavior softer and more manageable in long sessions, for lighter riders or in stronger winds.

Specific tuning for each size

The Mach 9 is not simply scaled in its various sizes, but specifically optimized across the entire range. This allows for a more accurate response for each size, improving comfort, stiffness, reflex, and ease of use according to the sail's actual target.

Development by size

5.0 softer and more controllable

The 5.0 has been made softer than the previous generation to offer greater control and comfort in strong wind conditions. The result is a more manageable sail in the high end, less fatiguing, and more balanced in gusts.

5.5 and 6.5 more reactive

The intermediate sizes gain stiffness to offer a sharper response at the start and greater drive when sailing in race trim. This makes the sail more responsive and effective in dynamic situations and in race traffic.

7.5 and 8.5 optimized for large slalom boards

The larger sizes adopt a dedicated curve that favors more upward flex and better reflex out of the low end. In practice, they help larger slalom boards to get going sooner and develop speed with greater ease.

Construction and setup

Direct power transfer

The construction is oriented towards providing direct power transmission, with an immediate response feel and a stable profile under load. This approach improves acceleration efficiency and supports fast, composed sailing.

Stable profile and range management

The sail is designed to maintain solid and predictable behavior, combining thrust, control, and advanced tuning. The wide range allows each size to be used in more conditions, making the quiver more efficient.
