V8 HELIUM – 100% PURE PLANING
NeilPryde is proud to introduce a new addition to the V-Series flat water
sail collection - the all-new V8 HELIUM.
The V8 HELIUM is a light wind specialist sail,
designed to deliver powerful planing performance on days where most other
sails just stay on the beach. With five batten construction for lightweight
handling, twin UltraCams for super-smooth rotation, and a deep profile for
all the low-end acceleration you'd expect from a sail with a V8 performance
pedigree.
So now, even in light air, The Wind Can Tell The Difference.

V-SERIES T-shirt.

BACKGROUND
The Helium concept originated in response to a German Surf magazine
competition to find a smaller, more powerful, sail for use in light winds.
The sail presented by NeilPryde went on the win the competition and another
year later was developed further to integrate UltraCam Performance
Technology and join the NeilPryde V Series as the V8 HELIUM.
CHOOSING THE RIGHT SAIL
“A unique feature of the V8 Helium is the sizing. The V8 Helium comes in
three sizes, but contrary to regular sails these are not designed to cover
different wind conditions but are in fact all designed to be early planing,
extreme light-wind specialised sails and the design of each size is
optimised to deliver this performance to a specific body weight. For this
reason a light weight person should choose the 6.5, a medium weight is
suited to the 7.5 and heavier riders should choose the 8.5 for uncompromised
light wind performance.”

KEY DIFFERENCES BETWEEN A V6, V8 and V8 HELIUM
There are three key points of difference between the V8 Helium and the V6
and V8 sails; the number of battens, the design of the luff curve and the
outline.
The V8 Helium has just 5 battens. The large spacing between battens really
improves the low end performance of the sail as it makes the profile softer,
easier to inflate in light wind and of course brings the weight of the sail
down.
The V8 Helium features a "light-wind" luff curve. The luff curve is designed
in a way that top of the sail opens with very moderate downhaul tension (low
tension in the body makes sail softer and perform especially well in light
air), even though the actual maximum luff curve is slightly higher than on
V8. This is done by having a relatively straight section in the very top
that will get the head to twist of early while the round mid section will
support the mid-leech which is critical for early planning and upwind
performance. Since the downhaul tension is considerably less than on V8 and
less than on V6 it was important to adjust the bottom of the luff curve in
order to control the entry depth; with regular luff curve in the bottom the
low downhaul tension would result in excessive fullness at the cams. For
best light wind performance you want a full profile, but a smooth entry to
reduce drag in light air.
The V8 Helium outline features a relatively small head and longer boom than
on the V6 and V8 sails. The idea was to bring most of the sail area in to
the "supported triangle", so the head roach was minimized.
The actual shaping numbers of the V8 Helium are very similar to V6 and V8,
although the profile distribution is a bit further back. The additional
fullness you will see on the rigged sail is result of fewer battens and very
specific luff curve (as explained above) and not result of very full
shaping. Excessive shaping will, of course, add depth to the profile, but it
will at the same time make sail stiff, so to certain extent it would work
against the objective of early planing and optimal light wind performance.
