MACH 8
PRO SLALOM
ENGINEERED TO WIN.
Eight years of race-winning DNA shifts up another notch with the Mach 8. Re-engineered entry profiles create a slippery, low-drag configuration that cuts through any wind state. The wider head works in harmony with size-specific luff curves to bend the mast perfectly – instant power when you need it, controlled twist when you don’t.
This new generation racing machine glides through lulls and gusts with minimal adjustment needed. A stable, more natural trim delivers higher average speeds while reducing rider fatigue. The advanced aerodynamics deliver new levels of peak performance, but the real advantage is the ease with which these speeds are achieved.
Xtended Range technology means bigger gaps between sizes are possible. Deeper, more powerful profiles are locked in place with added skin tension to enhance control and stability at both ends of the wind range. Wider range. Zero limits.

TECHNOLOGY
> 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 7.
> Optimised aerodynamics - By aligning the battens with the direction of airflow drag has been reduced. Clean panels with minimal seams further improve the aerodynamics.
> Leading edge - Tuned entry with a finer leading edge rotation for reduced drag.
> 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.
> New sleeve panel layout - A NEW SLEEVE CONSTRUCTION METHOD CONNECTS THE SAIL FROM TOP TO BOTTOM AND WITH THE SAIL BODY.
> 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.
> Spiderfibre - SpiderFibre on the leech of the sail massively increases the perimeter strength and inhibits vertical stretch between the sail panels.
> Performance monofilm construction - Monofilm Construction to maximise performance and minimize weight. Construction mimics the exact sail prototypes that were tested by our racers.
> Boom height reference - Boom height gauge for ease of reference.
> Increased mid-leech twist - The mid leech has been opened more to decrease drag. Fast and slippery.
> High visibility sleeve - Keep your opponents and surroundings in check while racing.
> XL performance - 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.
> 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.
> Auto-adjust foot - Previously we focused on drag reduction in the upper parts of the sail, but with Mach 6, 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.
> 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.
> 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.

Great product, fits very well

Recently bought the above product and I received quick first class service. The product was with me in few days even though I live at the other end of country. First class service from the team. Many thanks

Really helpful staff, prompt delivery

It’s jut perfect .. thank you so much

All came really quickly and efficiently 👍🏻
Very good service very helpful and good product.. thank you for all the team

Fantastic all round!

Very good for sea dipping 👍

Prompt. delivery, worked as expected, one Blade sail repaired🙂

Works fine

Works well

I ordered easily and the voucher arrived promptly. Also an email from the business was really nice.

Great equipment, decent price and very prompt delivery.

I have used this board on flat water in calm and very windy conditions. I really like this board it handles really well, is a pleasure to paddle and seems quite quick. one of the reasons for choosing this board was it is designed for lighter weight paddlers, it really does fit the bill in that respect. All in all a brilliant board. In addition the service I received from Poole Harbour Watersports was excellent.

Amazing product
