| “CORIOLAN VI” - Bis 77’ MultiYacht
sailing catamaran
 French
Naval architects Marc Van Peteghem & Vincent Lauriot-Prévost
the creators of a large number of the 60’ catamaran ORMA
fleet and of ocean going catamarans ranging from 12 metres to over
40 metres LOA have been commissioned to design the new Bis 77’ for
the Italian yard MultiYacht Compositi di Senigallia (AN).
The Owners brief called for a high performance
yacht, very stiff and light but with very detailed luxury interiors, so from the
start the use of composites was imposed. Trimarine was called in
to manage the project given it’s extensive experience in
large composite structures. Trimarine’s brief included the
assistance to the yard’s management in the choice and organization
of a facility capable of housing a 24 m x
11 m hull and then the
construction follow up, systems installation and launching of the
yacht.
Most of the first year was dedicated to the production of the moulds
which were designed with a particular assembly procedure in mind
to facilitate production and taking into consideration the large
dimensions of the yacht and the geometry of the building facility.
 Hull,
deck and superstructure was of vacuum consolidated
sandwich construction using glass and carbon fibres laminated over
variable thickness and density PVC foam cores with epoxy resin. The result was structural
weight of 7500kg a remarkable value if we consider the over 650
sqm surface of the vessel.
The second year saw Trimarine and Multiyacht’s efforts dedicated
to the installation of onboard systems and interior furniture with
special attention to the very tight weight budget.
During the summer of 2003 “Coriolan VI” was delivered
to a very experienced Owner, a keen upwind sailor that was very
positively impressed with the sailing ability of the Bis 77’,
by far a better performer than the typical large cruising cats.
