The 8th Vend e lobe, the 70-day, solo non-stop race around the world without
assistance, sails back to Les Sables d lonne in early anuary. This 2016-2017
Vend e lobe is the first one in which seven new IM CA 60 boats fitted with
foils are competing. a 14-metre long footbridge entirely made of biocomposites.

W

ith twelve out of the 29
Vendée Globe boats to
their credit, naval architecture studio VPLP Design,
in association with Guillaume
Verdier, is leading the fleet.
IMOCA (for International
Monohull Open Class Association) is a class of ocean-going boats that brings together
the world's best solo skippers. Its
60-foot monohulls are some of
the fastest contemporary racing

Imoca speeding 30 knots

boats. Made of composite materials, they are designed to be as
lightweight as possible and tough
enough to withstand open-sea
sailing conditions, with strict safety requirements for both sailors
and architects. For example, each
boat must have the proven capacity to right itself without outside
assistance.
Two studios, and foils!
Two naval architectural design
studios, VPLP and Guillaume
Verdier, partnered in Vannes,
France, to design and build

twelve of the IMOCA boats that
set sail in November 2016. The
"composite" innovation of 2016
comes in the form of foils on six
of these boats to increase their
performance. Quentin Lucet,
senior architect in charge of these
projects (and a confirmed sailor
himself) explains: "Thanks to the
foils, we can now lower the weight
of a boat without losing torque, and
this is the main new thing of the decade! We just pull out the foil, which
is in the water. It provides lift: the
more it pushes, the more the boat
lifts. The foil gives the boat wings,
so to speak, enabling it to gain two
days in a Vendée Globe race." (The
only time the foil does not serve
is during low-force winds.) These
composite parts are very expensive - two foils cost 300,000 euros on average. A foil weighs 130
kilograms and is full of carbon
fibre, so it can support up to 3-4
metric tons of weight. Two different processes are used in the
foil design: infusion for the Safran
and the Dutch No Way Back, and

N 110 January-February 2017 /

autoclaved prepreg for the four
other IMOCA boats. "When it is
deployed, a foil generates a vertical
force to keep the boat from listing.
The faster a boat is going, the greater the force, and that keeps it from
listing. So the boat is faster and more
powerful. To compare, the boats
that sail now take on ballast in the
wind, as a counterweight. A foil can
have the same effect without having
to weigh the boat down by so much.
That is what is interesting!"
Because these architects are all
sailing buffs themselves, they
understand the language of sailors. Quentin Lucet was able to
test one of the IMOCA boats
that he built. He took the Hugo
Boss monohull out at night in a
fifteen-knot wind, and the boat
reached speeds of 26 knots! Now
that the foils have proved themselves, they are headed for the
cruising sector to enable the boats
in this category to go faster.
The drive to lower weight is extreme for these IMOCA boats,
which are as powerful as they are
