An exciting new era in America’s Cup racing was unveiled
on 20 November as the concept for the AC75, the class of boat
to be sailed in the 36th America’s Cup was released illustrating
a bold and modern vision for high performance fully foiling
monohull racing yachts.
The Emirates Team New Zealand and Luna Rossa design
teams have spent the last four months evaluating a wide range
of monohull concepts. Their goals have been to design a class
that will be challenging and demanding to sail, rewarding the top
level of skill for the crews; this concept could become the future
of racing and even cruising monohulls beyond the America’s Cup.
“It has been a phenomenal effort by Dan and the guys together
with Luna Rossa design team and there is a lot of excitement
building around the boat in the development and getting to this
point,” Grant Dalton, CEO Emirates Team New Zealand said.
“Our analysis of the performance of the foiling monohulls
tells us that once the boat is up and foiling, the boat has the
potential to be faster than an AC50 both upwind and downwind.”
“Auckland is in for a highly competitive summer of racing
in 2020 / 2021.”
The ground-breaking concept is achieved through the use of
twin canting T-foils, ballasted to provide righting-moment when
sailing, and roll stability at low speed.
The normal sailing mode sees the leeward foil lowered to
provide lift and enable foiling, with the windward foil raised
out of the water to maximise the lever-arm of the ballast and
reduce drag. In pre-starts and through manoeuvres, both foils
can be lowered to provide extra lift and roll control, also useful in
rougher sea conditions and providing a wider window for racing.
Although racing performance has been the cornerstone of
the design, consideration has had to be focused on the more
practical aspects of the boat in the shed and at the dock, where
both foils are canted right under the hull in order to provide
natural roll stability and to allow the yacht to fit into a standard
An underlying principle has been to provide affordable and
sustainable technology ‘trickle down’ to other sailing classes and
yachts. While recent America’s Cup multihulls have benefitted
from the power and control of rigid wing sails, there has been
no transfer of this technology to the rigs of other sailing classes.
In tandem with the innovations of the foiling system, Emirates
Team New Zealand and Luna Rossa are investigating a number
of possible innovations for the AC75’s rig, with the requirement
that the rig need not be craned in and out each day. This research
work is ongoing as different concepts are evaluated, and details
will be released with the AC75 Class Rule before March 31st, 2018.
The AC75 will foil-tack and foil-gybe with only small
manoeuvring losses, and given the speed and the ease at which
the boats can turn the classic pre-starts of the America’s Cup
are set to make an exciting comeback. Sail handling will also
become important, with cross-overs to code zero sails in light
“ The AC 75 will be an extremely high-performance yacht,
challenging to sail, and will require an athletic and very talented
crew,” said Max Sirena. Team Director of Luna Rossa Challenge.
“Every crew member will have a key role both in the
manoeuvres and in racing the boat; the tight crossings and the
circling in the pre-starts – which are part of the America’s Cup
tradition – will be back on show, but at significant higher speeds.”
