Under
Sail
High
performance is an essential part of the HiP30 concept and
design. We have produced some preliminary polar plots obtained
from a computer VPP (Velocity Prediction Program) as shown
here.
The
polar plots are for lines of boat speed in winds of 6,8,10,12,14,16
and 20 knots, there is no line for 18 knots. The upper lines
are for windward sailing and the lower group are for downwind.
These
initial plots showed that the HiP30 should plane in 20 knots
of wind and reach a decent speed. It may even plane in 18
knots. Upwind she performs very well and is exceptional
in light to medium winds.
Downwind
it seems to be worth carrying the asymmetric from about
80 degrees to the wind.
This
information has helped us to define the keel and bulb shapes
and optimise the sail plan and rigging.
We are
confident that these early predictions will be exceeded
once sail trials commence and our target of exceptional
performance will be easily achieved.
