This high abrasion area is made from only 1 panel and does not carry any exposed seams, preventing any potential weak point in this area. As a result, seam creep and seam-related failure have been eliminated.

Tuned entry with a finer leading edge rotation for reduced drag.

By aligning the battens with the direction of airflow drag has been reduced. Clean panels with minimal seams further improve the aerodynamics.

The DDT 4 and DDT 5 tensioners directly connect the tube batten to the leech of the sail. This new design eliminates the heavy section of the tube that is needed for the standard batten tensioner. And being smaller, it has superior aerodynamics. It is used on all lower tension battens in the OVERDRIVE and the MACH 5.

The mid leech has been opened more to decrease drag. Fast and slippery.

POSITION 1:

This is the recommended setting and carries the adjustable outhaul fitting. It creates the perfect balance between a comfortable clew height and leech tension. This is the setting that Matteo Iachino will use for 99% of PWA slalom races.

POSITION 2:

This setting is lower and further in. It softens the feel of the sail and may be more comfortable for smaller, lighter riders looking for more control in higher winds.

Monofilm Construction to maximise performance and minimize weight. Construction mimics the exact sail prototypes that were tested by our racers.

Boom height gauge for ease of reference.

Keep your opponents and surroundings in check while racing.

Capitalizing on the performance and proven durability of the Apex Pro mast, more luff curve has increased skin tension to lock the profile low and forward where it can be most easily controlled.

Roller tack pulleys are matched to the sails downhaul requirements and aligned for friction free downhauling and threading ease. Rig your sails with the Severne Hardware Division extensions for function and simplicity.

Used on the MACH 5, the XL Cam maximizes leading edge stability by allowing increased cam pressure to be distributed over a wider surface area.
Rotation is improved by the increased the leverage of the longer cam.
Mast wear is reduced due to less friction from the 8 rollers.

Previously we focused on drag reduction in the upper parts of the sail, but with the Mach 4 and OverDrive M4 even the foot sections have been analysed and refined. Less tension on the foot edge combined with more forward oriented shaping allows the foot to twist and auto-adjust.

SpiderFibre on the leech of the sail massively increases the perimeter strength and inhibits vertical stretch between the sail panels.

Automating the dynamic twist has enabled us to remove the Reflex system. The lower leech twist is now pre-loaded to mimic the twist pattern induced by the Reflex batten under load. Significant advantages are simpler tuning, reduced weight, and increased durability.

A single panel in the foot area with hidden load patches and zero exposed stitching eliminates seam abrasion and seam creep in this high load area. Maximum durability and minimum weight.
