NeilPryde RS Slalom MK6 Windsurf Sail 2015

Quadruple Luff Panel Layout
MK6 features four continuous luff panels that carry most of the sail body shaping. This configuration stabilises the critical section draft position while also providing lightweight yet stretch-resistant way of increasing the film thickness proportional with downhaul load distribution. Continuous panels eliminated horizontal seams crossing the highly loaded leading edge, which increases response of the sail as well as durability. Introduction of this extremely stable leading edge platform that is able to take very high downhaul loads allowed us to integrate Clear Pocket construction in the remaining sail body.

Component Sleeve Construction
The MK6 sleeve is constructed by combining different materials with specific properties to achieve optimum profile entry stability and elasticity, critical for rotation and light weight. The front upper section (1) is made from lightweight woven material that has necessary elasticity and durability to resist wear from direct contact with the mast. Behind this panel there is a low stretch ultra ArmourWeb section (2) that takes high downhaul tension and is critical in stabilising the profile entry, providing smooth bridging between Ultra Cams. Inserted between this ultra panel and the sail body is a very lightweight, rip-resistant laminated film/taffeta with ultra yarns (3). Film controls the stretch, ultra provides ultimate rip resistance and taffeta is crucial for stitch holding. Bottom part of the sleeve is finished using our Luff Glide material as on other NeilPryde sails. This material combines very low friction against the mast (important for smooth rotation) with excellent durability and necessary elasticity in the bottom part.

Clear Pocket Batten Sleeve
On the MK6, overlapping body panels create a sleeve for battens, eliminating the need for traditional separate batten pockets. This obviously saves on unnecessary weight and simplifies construction. Much more importantly, Clear Pockets create a fully symmetrical batten cavity, eliminating the tendency of traditional batten pockets to load differently from one tack to another. Traditional batten pockets, sewn on one side of the sail make the sail body set deeper when they are on the leeward side of the profile than when they are on the windward side. Clear Pockets, set the battens effectively in the middle of the horizontal cross section of the sail, avoiding this problem.

Forceline
The clew area of the MK6 features a custom laminated Kevlar™ Forceline Panel for load distribution. Load spreading Kevlar™ strips are laminated directly onto the sail body, fanning from the point load at the grommet and continuously crossing over panel joints. This not only provides optimum load distribution but it makes for extremely lightweight yet strong construction eliminating any air pockets present in traditional patch construction.

Features

Integrated Compact Clew
Eliminates the cutout at the clew and connects the foot area with the leech by closing the sail behind the boom end. This results in improved handling, stability and wind range. Available on speed and slalom sizes.

Clew Batten
Providing clew support and load distribution.

Mini Batcams
Streamline and reduce weight in critical upper leech.

Ultracam
Innovative suspended camber system dramatically improves sail rotation and acceleration out of gybes. Simultaneous tuning of battens and cambers makes the sail easy to tune.

Carbon Leech Mini Battens
Provide max support with minimum weight.

Batten Chafe Protection
Abrasion resistant PU print to help protect the battens from damage caused by rigging or boom contact.

Kevlar Batten Bridges
To distribute the high downhaul load crossing the battens

Aerodynamic Boom cutout closure
Prevents the apparent wind from blowing into the mast sleeve and generating drag.

Dual Clew Eyelets
Allowing fine individual tuning.

Three-Piece Cam Battens
A 3-piece batten provides the framework for the design of a smooth, lightweight and stable sail profile.

A. Carbon/fiberglass tube: stiffest section.

B. Hollow mid-section: medium stiffness.

C. Precision Tapered CNC Batten: variable stiffness.

Dynamic Luff Sleeve Shaping
A. Increasing the width of the double surface leading edge in the area where the profile is deepest, ie in front of the rider, helps to keep the draft stable in this critical area.

B. Decreasing the width of the double luff in the head allows the sail to twist off more smoothly and under less load. This reduces tension on the leech.

Batcam Screw Adjuster
For easy and precise tension application.
