Shear Power<br />
The challenge to design a 10th<br />
<strong>Z1</strong> Ad<br />
anniversary signature sail for<br />

by Barry Spanier <strong>in</strong> <strong>the</strong> <strong>Z1</strong>.<br />

results expected by <strong>the</strong> champion.<br />
The <strong>Z1</strong> is a pure race<br />
sail with excellent<br />
form stability,<br />
superior upw<strong>in</strong>d<br />
performance, and <strong>the</strong> smoo<strong>the</strong>st<br />
acceleration and control ever. Dur<strong>in</strong>g <strong>the</strong> close of<br />

outer dot for medium w<strong>in</strong>ds<br />

The Shear Tip<br />
Barry Spanier’s <strong>in</strong>spiration<br />
for <strong>the</strong> Shear Tip came from<br />
Maui Loft Manager and<br />
fly<strong>in</strong>g enthusiast David<br />
Starbuck whose work <strong>in</strong><br />
light aviation and hang<br />
glid<strong>in</strong>g prompted his<br />
experiments with <strong>the</strong> new<br />
concept. The deeper profile<br />
carried all <strong>the</strong> way to <strong>the</strong><br />
head delivers <strong>the</strong> <strong>power</strong> and<br />
acceleration of lower aspect<br />
sails <strong>in</strong> a compact,<br />
manageable package that<br />
holds its shape and rema<strong>in</strong>s<br />
stable even at top speeds.<br />
The Shear Tip not only helps<br />
to m<strong>in</strong>imize drag, it is a total<br />
system for control of leech<br />
twist and shape <strong>in</strong> <strong>the</strong> foil<br />
tip. It will redef<strong>in</strong>e <strong>the</strong><br />
planform and look of future<br />
<strong>Neil</strong> <strong>Pryde</strong> sails.

◊ M<strong>in</strong>imizes Drag<br />
The outl<strong>in</strong>e of <strong>the</strong> Shear Tip<br />
reduces drag by encourag<strong>in</strong>g <strong>the</strong><br />
air to flow off a po<strong>in</strong>t. This reduces<br />
<strong>the</strong> vortex giv<strong>in</strong>g <strong>the</strong> sail superior<br />
upw<strong>in</strong>d performance and control<br />
while reach<strong>in</strong>g at top speeds.<br />
◊ No Need For Specially<br />
Required Masts<br />
The sails have been designed<br />
around exist<strong>in</strong>g <strong>Neil</strong> <strong>Pryde</strong> CK95<br />
products.<br />
◊ Only Four Cams<br />
Because <strong>the</strong> Shear Tip supports<br />
<strong>the</strong> full width of <strong>the</strong> head sections<br />
<strong>the</strong> luff now sets up nicely with<br />
only four cams mak<strong>in</strong>g it<br />
lightweight and easy to rig.<br />
◊ The Shear Tip arm rolls up <strong>in</strong>to<br />
<strong>the</strong> sail parallel to <strong>the</strong> battens so<br />
noth<strong>in</strong>g has to be disconnected.

“We had every reason to believe <strong>the</strong> <strong>Z1</strong> was go<strong>in</strong>g to be a success based on <strong>the</strong><br />
reaction of <strong>the</strong> sailors. People were stunned at how fast Bjorn was go<strong>in</strong>g <strong>in</strong> Sylt,<br />
right from <strong>the</strong> beg<strong>in</strong>n<strong>in</strong>g it was no contest. Bjorn had about an hour on <strong>the</strong> new<br />
sail and decided he’d ra<strong>the</strong>r be rac<strong>in</strong>g on <strong>the</strong> <strong>Z1</strong> than anyth<strong>in</strong>g else. This has<br />
given us a <strong>lot</strong> of confidence, to have <strong>the</strong> enthusiasm of <strong>the</strong> sailors driv<strong>in</strong>g <strong>the</strong><br />
whole th<strong>in</strong>g.”<br />
-Barry Spanier<br />
“I put <strong>the</strong> first Shear Tip on a small recreational sail and <strong>the</strong> ease of handl<strong>in</strong>g and<br />
<strong>in</strong>creased performance was obvious. What was especially <strong>in</strong>terest<strong>in</strong>g was <strong>the</strong><br />
improvement <strong>in</strong> control when over<strong>power</strong>ed, I knew that this would have<br />
application throughout <strong>the</strong> entire spectrum of designs. We were fortunate to have<br />
immediate success and that spurred <strong>the</strong> enthusiasm of <strong>the</strong> racers...I have been<br />
<strong>in</strong>volved <strong>in</strong> hang glid<strong>in</strong>g and light aviation for twenty five years so I look at sails<br />
as w<strong>in</strong>gs. It was recent developments <strong>in</strong> aviation and my understand<strong>in</strong>g of flex<br />
w<strong>in</strong>g gliders that <strong>in</strong>spired <strong>the</strong> development of <strong>the</strong> Shear Tip.”<br />
-David Starbuck<br />
“The <strong>Z1</strong> is a fast, efficient sail. The twisted leach rema<strong>in</strong>s <strong>in</strong> constant tension<br />
right to <strong>the</strong> top and this feels like it creates <strong>more</strong> lift over <strong>the</strong> entire foil. The<br />
result is a sail that is early to plane, quicker to accelerate and <strong>more</strong> importantly<br />
for us has a faster top end.”<br />
-Scott Fenton
A Breath of Fresh Air<br />
The UltralightXL is a new light w<strong>in</strong>d sail designed by Philippe Darieux. It is a simple<br />
concept of one design, one size for freeride sail<strong>in</strong>g. The orig<strong>in</strong>al brief targeted super<br />
early plan<strong>in</strong>g to open up a new market of ultra light w<strong>in</strong>d sail<strong>in</strong>g and to make <strong>the</strong> sail<br />
as simple and light as possible to provide easy rigg<strong>in</strong>g and easy handl<strong>in</strong>g. This was an<br />
enormous task for Philippe and after a year of development, we are now confident<br />
that we have achieved our objectives.<br />
The luff length of <strong>the</strong> Ultra Light is very<br />
long <strong>in</strong> order to obta<strong>in</strong> a high aspect<br />
ratio that would generate enough<br />
lift to pull <strong>the</strong> board onto a plane <strong>in</strong><br />
marg<strong>in</strong>al conditions.<br />
This high aspect ratio generates <strong>the</strong> dynamic lift needed to get <strong>the</strong> traditionally<br />
heavier freeride boards (300 to 330cm long) <strong>in</strong>to a plane. The result is considerable<br />
head load, and a profile that goes high up <strong>in</strong> <strong>the</strong> sail to catch<br />
<strong>the</strong> w<strong>in</strong>ds fur<strong>the</strong>r up. In order to counter <strong>the</strong> control problems<br />
that generally come with a sail of this size, <strong>the</strong> leech is<br />
much ‘softer’ than o<strong>the</strong>r <strong>more</strong><br />
traditional designs and <strong>the</strong> whole<br />
leech twists giv<strong>in</strong>g you all <strong>the</strong><br />
UL Ad<br />
control that is needed.

Design brief<br />
New RAF design approach to provide easy handl<strong>in</strong>g, soft, breath<strong>in</strong>g response and early plan<strong>in</strong>g <strong>in</strong> 8-12 knots.<br />
To be suitable for production freeride boards and <strong>the</strong> latest light w<strong>in</strong>d board designs.<br />
Design emphasis<br />
Utilise <strong>the</strong> latest materials and CAD/CAM design technology to create <strong>the</strong> lightest, most efficient sail possible.<br />
Easy trimm<strong>in</strong>g through a unique mast extension.<br />
Design realization<br />
Use a high aspect ratio design with a deep profile all <strong>the</strong> way to <strong>the</strong> head for optimum light w<strong>in</strong>d performance<br />
but ease leech tension to ma<strong>in</strong>ta<strong>in</strong> light, easy handl<strong>in</strong>g.

“Work<strong>in</strong>g on <strong>the</strong> Ultralight program was very excit<strong>in</strong>g, right from <strong>the</strong> beg<strong>in</strong>n<strong>in</strong>g I<br />
knew <strong>the</strong> new concept of ‘extra soft rigs’ would take <strong>the</strong> design of light w<strong>in</strong>d sails to<br />
a new level. Because of <strong>the</strong> flexible rig <strong>the</strong> Ultralight performs so well <strong>in</strong> light<br />
w<strong>in</strong>ds, and gives a soft feel<strong>in</strong>g when sail<strong>in</strong>g.”<br />
-Philippe Darrieux<br />
“Ultra quick to plane, ultra light and ultra easy, this pure RAF design rigs<br />
<strong>in</strong>stantly, handles like a fea<strong>the</strong>r and is perfect if used with three meter Freeride<br />
boards.”<br />
-Patrice Belbeoc’h<br />
“A new concept <strong>in</strong> light w<strong>in</strong>d sail<strong>in</strong>g. The ultra light eng<strong>in</strong>eer<strong>in</strong>g makes <strong>the</strong> sail as<br />
easy to handle as it is to rig and it planes while o<strong>the</strong>rs are parked.”<br />
