MACH3

RACE

The Mach3 development started in January with Matteo Iachino and Gonzalo Costa Hoevel. The goal was to improve low-end acceleration and power without negatively affecting the top end performance or ultralight handling.
We achieved this primarily by raising the Centre of Lift higher in the sail, increasing the leverage. Clew height and geometry were then tuned to keep the light handling characteristics and feel. With 7 battens in all sizes, the Mach3 inflates faster and reacts to gusts quicker for epic acceleration. Less battens means less weight. One of the lightest race sails on the market,
if not the lightest.

Pure Performance.

TECHNOLOGY

Severne Mach3 2020 - racing
pointer

SEAMLESS HEAD PANEL

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.

pointer

LEADING EDGE

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

pointer

OPTIMIZED AERODYNAMICS

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

pointer
DIRECT DRIVE TENSIONERS

DIRECT DRIVE TENSIONERS

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 tube that is needed for the standard batten tensioner and being smaller, has superior aerodynamics. It is used on all lower tension battens in the OVERDRIVE M2 and the MACH 2.

pointer

INCREASED MID-LEECH TWIST

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

pointer
OPTIONAL CLEW POSITIONS

OPTIONAL CLEW POSITIONS

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 and Tristan Algret will use for 99% of their 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.

pointer

PERFORMANCE MONOFILM CONSTRUCTION

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

pointer

BOOM HEIGHT REFERENCE

Boom height gauge for ease of reference.

pointer

APEX SKIN TENSION

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.

pointer

3&4 ROLLER TACK PULLEY

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.

pointer
XL PERFORMANCE

XL PERFORMANCE

Used on the MACH 2, 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.

pointer

AUTO-ADJUST FOOT

Previously we focused on drag reduction in the upper parts of the sail, but with the Mach 2 and OverDrive M2 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.

pointer
SPIDERFIBRE RACE

SPIDERFIBRE

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

pointer

ACCELERATED LEECH

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.

pointer
SDM CAM V2.0

SDM CAM V2.0

A redesigned SDM cam improves rotation, ease of rigging and allows minimal downhaul settings without risk of the cam popping off.

pointer

SEAMLESS FOOT CONSTRUCTION

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.
