RIB
Rigid-hulled, inflatable powerboat
Polynt Group's Soffio project consists of a
fast rigid-hulled inflatable boat (RIB) with
superior abilities thanks to a specially
modified epoxy vinylester resin toughened
with a reactive rubber.
T
he innovative part of
this RIB powerboat
resides in the materials used for its hull, as well
as a different production
technology. In this project, the hull is specifically
designed to enhance the dynamic characteristics of the
boat, rendering it capable to
compete in races with more
traditional crafts already
available on the market.
The importance
of picking the right
materials
ically a modified epoxy vinylester resin toughened with
a reactive rubber. The resin
ensured excellent mechanical properties, adhesion to
the fibres (both carbon and
glass) as well as toughness
and fatigue resistance during
the races themselves. This
was particularly important
considering the problems
inherent to stress in the
composite parts.
The chosen process is an
optimized infusion technology with controlled temperature, allowing the infusion
of a medium/high viscosity
resin. Thus, shrinkage was
reduced during the polymerization step and the final
toughness was enhanced.
Using composite parts with
appropriate processes made
The boat is composed of

ingful goal nowadays.
This boat can compete
easily with a powerboat
equipped with an in-board
engine of about 2500 HP,
showing a brutal acceleration, great handling, stability and less hydrodynamic
resistance. The concept of
the designer and engineer is
to go faster with a modest
power, pushing the concept
and construction of composite structures to the extreme.
From conception
to performance
The project came to be
thanks to the initial idea of
producing a RIB racing boat
similar to standard boats but
with a significantly different
production technology. The
goal was to achieve outstanding performance and
be competitive amongst the
most powerful racing boats
in various championships.
Using composite materials
allowed for lightweight but
still tough structures with an
optimal weight distribution
and a low barycentre.
The hull on these boats is
specifically designed to enhance their dynamic characteristics, providing stability,
excellent buoyancy, "dry"
navigation and a remarkable
economy at cruise speed.
What's more, every model
is completely engineered
using advanced 3D design
(rendering) software.
The market potential resides
in the yachting area for
small leisure boats, and it
brings new opportunities to
the racing world. n
