Farr 40 Spinnaker© North Sails
V-Series Spinnakers
Significant
advances in design software and wind tunnel testing have spurred a
surge in downwind sail development at North Sails.
Experts have
long known that your biggest gains can be achieved after you round the
windward mark. It's the reason why North Sails invests more research
and development (R&D) dollars in downwind sail development than any
sailmaker. Although North's revolutionary 3DL® molded sail
technology has captured headlines for more than 10 years, our downwind
sail development has been progressing at an equal pace. Advances in
design and production software, combined with a breakthrough in wind
tunnel testing, and computer computer wind slow simulation has launched
a new family of North downwind sails that are both faster and easier to
trim over a broader wind spectrum.
Today's generation of
lighter, faster-accelerating offshore one-designs and sport boats also
experience huge fluctuations in apparent wind speed and direction. For
these boats, V-Series spinnakers will deliver more drive more of the
time. All V-Series designs are optimized using North's Flight™ and Flow
/ Membrane™ design analysis software (integrating data from the twisted
flow wind tunnel) and are molded both horizontally and vertically using
North's proprietary Spine™ 3D shaping program. The result is a profile
that is exceptionally fair for smoother flow, improved stability and
easier trim.
Sport and sprit boat sailors now can choose between V-Series Asymmetric reaching molds optimized for point-to-point racing and V-Series Symmetric molds.
