The goal of Miss Wisconsin
is to exceed an average speed of 143 mph while traversing a windward
and return course. Back in 1938 John D. Buckstaff had sailed his
class A, stern-steerer Debutante to a recorded 143 mph. In the 1950's,
during a regatta on Winnebago, Chuck Nevitt in an A class stern-steerer
was unofficially clocked doing 150 mph by a couple of spectators
In order to work, to
establish a record for a windward and return course, the boat must
be designed to sail in a Fresh Gale (Beaufort Wind Scale), i.e.
winds between 39 and 46 mph. A Fresh Gale, by definition, will break
limbs off of trees and is difficult to stand up against. Therefore
the Boat and its rigging must be built strong enough to withstand
the force of the wind and perform the task it was designed to do
without destroying itself.
Miss Wisconsin has been
designed with only one purpose in mind, to achieve speeds upwards
of 200 mph. The boat is purely a wind-powered vehicle. There is
no stored energy in this machine. What makes her go is a combination
of airfoils. The mast is, in effect, an airfoil creating positive
and negative pressures. This difference in pressure creates the
wind that drives the boat forward. Daryl Lenz, A&P, airplane
builder and director of aircraft maintenance for EAA, refers to
the boat as, "that low-flying aircraft we are building".
