Construction |
Insulation,
ventilation and solar protection
Thermal insulation has been developed to guarantee
comfortable and
well-ventilated living, even in very hot weather. The sandwich
deck ensures constant insulation and the side ventilation is particularly
efficient, even in the rain (Fig.12).
All our head linings are insulating and ultra light. The large coach-roof portholes come with
external isothermic curtains – the most efficient way to avoid the greenhouse
effect by eliminating 90 per cent of the solar rays. These curtains also bring you privacy, while
giving you a view outside simultaneously.
Large opening panels provide excellent ventilation to the salon and the sizable sliding door, creates highly sociable environment.
Each porthole is equipped with a shutter and mosquito net which allow permanent ventilation and protection even in mosquito invaded areas!
All the furniture
are made of sandwich
The Catana have an unrivaled finish. It’s a well-know fact – and it shows. What you cannot see is that all that beautiful wood and fine cabinetwork do not weight down the boat. All the materials used for the boat’s furniture , the cabin sole, liners and ceilings, have an extremely low density, less than one. The whole joinery is made of foam-cored sandwich, finely veneered. This combines aesthetics, stiffness, solidity and light weight. The elegant interior of your Catana weighs several hundred kilos less than that of a classic boat.
The accommodation:
great comfort and living quality
A Catana is extremely spacious. With its 360 degree panoramic view, you’ll be surprised at the space and stowage room in the salon. Its direct access to the cockpit acts as the central living area of the boat. The hulls have been designed for your relaxation and comfort. Each cabin is light and airy. The functional heads, which have separate showers, are a delight to use and have been greatly appreciated by our customers.
The sandwich construction
Catana boats are built entirely of sandwich construction under vacuum. For a catamaran where each hull sails over different waves, its strength and long life depend on the rigidity and consistency of the boat’s structure. The core of the hulls and bulkheads is made from PVC foam, with density of 75 kg/m3 and a minimum thickness of 20mm. The core of the decks, platform and coach-roof is made with foam up to 40mm thick.
(Fig.13) Sample of the hull: A – two coats antifouling; B –
thick gelcoat (8/10th); C – uni-directional, high-resistant,
tri-axial glass fiber; D – core of PVC foam; E – uni-directional, tri-axial
Twaron® materials.
The structure
integrity
Twenty-one structural bulkheads assure the rigidity and therefore long life of a Catana. The bulkheads are all of sandwich construction and reinforced with carbon fiber on both sides, fully laminated to the hulls, the deck, the coach-roof, the cockpit, and all the surrounding structures. The hull/deck joint is glued and completely laminated with several bi-axial materials.
The hull and deck of a Catana are as solid as though they were cast in one piece. A Catana will keep its shape with exceptional rigidity, not only because it is totally of sandwich construction, but also because it is reinforced by a uni-directional material which bears all the strain of bending and twisting. This method of construction guarantees an outstanding strength and lifespan.
Exclusive Twaron®
impact process
Twaron Impact is a construction process which mixes rigidity, lightness, and mechanical resistance, owing to a top-of-the-line, high resistant fiber. Twaron is used in the manufacture of military helmets, bullet-proof vests, and the aviation industry. It is several times more resistant than glass fiver and is particularly resistant to breaking under tension, scratching and collision.
Weight saving
Because of the weight saved by using 
this fiber, a cruising
boat can carry more water, fuel, and equipment without effecting its handling or
comfort in heavy seas: its performance is optimized. This aramid fiber used throughout the
interior skin of the sandwich is 10 times more resistant to puncturing and 3
times to tension than classic glass fiber.
Even in the case of hitting a floating object violently, you will be
able to continue your trip… more especially as the absorption by the foam of
the shock wave increases your safety.
Vinylester resin
Our exclusive Twaron impact construction process uses
Vinylester resin having the same mechanical properties as epoxy, but without
its disadvantages in application or further repair. The boat’s total unsinkability and the
enormous strength of the Twaron Impact structure, mean that a Catana can face
the most difficult seas in greater safety than any other boat available today,
whether a monohull or classic catamaran.
Longevity of your
Catana
That construction, combining several top-of-the-line technologies, guarantees an unrivalled long life for your Catana, and an excellent re-sale value.
