The Louis Vuitton Cup will begin in two weeks.
First raced in Newport in 1983, the regatta's thirtieth anniversary will
be celebrated.... in San Francisco. The America's Cup will be held there
September 7 to 21, 2013.
AC72 Drawings unveiled:
Here are the drawings of these flying cats:
It is amazing to see that the basic architecture has
stayed consistent among the contending teams.
In the America's Cup, design strategies differ, and
teams may feel pressure to assert that their ideas are the best.
Possibly
as a result, there have been few alterations to the design of the hulls between
each team's first and second boats.

The New Zealanders have modified their hull somewhat,
optimizing them for a faster take-off.

They
have also simplified and improved the aerodynamics of their tensile structure.

The Americans of Oracle have focused from the
beginning on lower resistance in both the water and the air, taking the risk of
limiting reserve buoyancy at the bows.

The details are extremely neat,
and the cockpits are deeper than ETNZ in order to shield the crew a bit.
However, looking closely at the sections, the forms of the forward portions of the hulls are more promising, relatively larger now in volume.
The Oracle
Team USA wing is a showpiece in terms of greater flexibility in tuning the
aerodynamic profile.
