MACH 5 _PRO SLALOM

ENGINEERED TO WIN. THE MACH 5 IS PURE SLALOM.

With a bias towards traditional, full-power slalom racing, significant updates to the Mach5 construction and geometry also improve performance when used on foil.

A higher aspect ratio reduces chord lengths, limiting any draft movement and increasing efficiency.
Back hand pressure has been maintained, so when you need to switch on the afterburners the power is ready.

The Mach5 features an open leech, reducing drag and improving aerodynamics.
The higher Centre of Power demands respect, but rewards with aggressive performance. Race to win.

TECHNOLOGY

Severne Mach4 2022 - Pro Slalom
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 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.

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 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.

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

HIGH VISIBILITY SLEEVE

Keep your opponents and surroundings in check while racing.

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 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.

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

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.

Can I use the Mach 5 for foiling?

Yes, the new Mach 5 range has been designed to work on both fin and foil.

Which Mach 5 sizes rig on RDM MASTS?

Sizes 6,2 and down are set up for rigging on an RDM mast and have been tested using RDM masts.

It is, however, possible to rig sizes from 6,2 and down on an SDM mast by replacing the RDM cambers with Severne SDM black cambers and adding spacers.

Sizes 7,0 and up only rig on SDM mast.

Which settings should I use when riding on foil and fin?

For use on the foil;

– Be careful not to over downhaul the sail.
– Use upper outhaul clew.
– User higher boom position.

For use on the fin;

– Use recommended settings.
– Use top outhaul clew for extra power, and lower outhaul clew for more release and control.

How much downhaul should I use on the Mach 5

Follow the recommended settings and work your way from there.

What is the difference between Mach 5 and HyperGlide 5

The Mach 5 is a slalom sail that is compatible with the foil. The HyperGlide 5 is a foil specific slalom sail.
