NEILPRYDE EXPRESSION SAIL 6.9

IGHT. POWERFUL. MANOEUVRABLE.

Light, powerful and extremely manoeuverable, the EXPRESSION is the crossover sail for those who windsurf predominantly flat water freestyle, but still want the versatility to go into waves should the opportunity arise. With pronounced, forward oriented shaping, a lower-aspect outline and reduction in luff-curve, the EXPRESSION delivers an unbeatable combination of power, manoeuvreability and control.

DESIGN OBJECTIVE

• The EXPRESSION must be suitable for beginners through to expert freestyle riders.
• The sail must be light, with neutral handling and easy rotation.
• Construction must be appropriate for regular wipe-outs and occasional wave use.
• The EXPRESSION must be powerful, and accelerate out of manoeuvres easily.
• The power must be close to the rider so that it is manageable, and can be used effectively but power can not be at the expense of control.
  
  For 2008:
• Improve the EXPRESSION's clew first sailing properties.
• Reduce the rotation and transition times allowing the sail to power and de-power quickly

ACHIEVED BY:

• Moderate shaping gives the EXPRESSION the most lift of the crossover sails.
• Low surface tension, and a moderately rotated sail body give the EXPRESSION easy rotation and a neutral feeling during manoeuvres.
• Light but strong construction, with a mix of X-Ply and monofilm provides an ideal combination of durability and weight.
  
  For 2008:
• A reduction in luff curve and downhaul translates into less surface tension. This allows the sail to quickly change mode from giving drive' to being neutral'.
• The EXPRESSION has the least rotated sail body in the crossover range. Rotation is improved due to the batten tips having a shorter distance to travel around the mast.
• A hollow' leech improves twist in the upper part of the sail and prevents the mid-leech from loading up and blowing out, improving the stability and control.
