Structure

GENERAL

Materials and scantlings will be defined taking into account the provisions of the Bureau Veritas NR500

regulation, edition 2006 amended in February 2008.

A finite element analysis (FEA) for the hull structure and superstructures is carried out to optimise scantlings. HULL, DECK and SUPERSTRUCTURES are built in composite materials, stratified and compressed by hand or vacuum infused. All materials used are premium quality, among them :

- Fiber glass.

- Kevlar and Aramat fibres.

- Carbon fibre.

- Balsa panel or checkerboard effect type Balteck.

- PVC foam.

- Polyester gelcoat.

- Isophtalic resin and orthophtalic polyester.

- Vinylester resin.

- Epoxy resin.

HULL

The hull is built by hand in sandwich composite in a female mould under controlled atmosphere.

Monolithic high resistance inner and outer skin made Kevlar(R), Aramat(R), glass fibre, resin matrix, balsa or PVC foam core (Glass Reinforced Plastic GRP). Resins used on exterior plies are Vinylester type to guaranty a maximal resistance to osmosis. Orthophtalic and isophtalic polyester resins are used for the rest of the stratification according to needs. Structure reinforcements, floor frames, stringers, omega are made of carbon and glass fibre skins, and PVC foam or balsa core.

The lamination process is carried out in accordance with approved drawings using layers of chopped strand mats and woven roving whose weave, weight and size are closely studied to give optimal mechanical resistance, following structural calculations carried out using the FEA method.

DECK AND SUPERSTRUCTURE

DECK is made of GRP sandwich. Monolithic high resistance inner and outer skin made of Kevlar(R), Aramat(R), glass fibre, resin matrix, balsa or PVC foam core (GRP). Structure reinforcements, omega are made of carbon and glass fibre skins, and PVC foam or balsa core sized by structural calculations carried out using the FEA method. The deck is laminated to the hull forming a highly resistant and watertight single piece. SUPERSTRUCTURE is made of GRP sandwich. Monolithic high resistance inner and outer skin, in glass fibre, resin matrix, balsa or PVC foam core (GRP). Structure reinforcements omega with carbon and glass fibre skins, and PVC foam or balsa core sized by structure calculations carried out using the FEA method. The superstructure is laminated to the deck forming a highly resistant and watertight single piece.

2.4 WATERTIGHT AND STRUCTURAL BULKHEADS

The hull is divided into longitudinal compartments using watertight bulkheads made of composite

fibreglass/resin/Balsa or PVC foam.

Structural bulkheads are vacuum infused under and covered with decorative elements.

2.5 FRAMES AND STRINGERS

The stringers, floor-frames, structural hull and bottom strainers are in vacuum moulded GRP or in marine plywood laminated to the hull. Drain holes are provided in all bottoms.

2.6 FLOORS

CABIN FLOORS : In vacuum moulded GRP or marine plywood, laminated to the hull, with access doors to facilitate equipment inspection under the floors.

ENGINE ROOM FLOORS: Removable 5mm aluminium antiskid plates installed on rubber seals to avoid vibrations.

GARAGE FLOOR AND CEILING: Lacquered white ceiling. Nonslip floor light grey painting.

2.7 TANKS

Fuel tanks are made of 5086 aluminium and are tested under pressure, in the presence of inspectors from the classification society, before their installation.

Fresh, grey and black water tanks are integrated to the hull, laminated onboard and protected by a top coat adapted to each use and approved following the same procedure.

2.8 PAINTING

2.8.1 Hull

The hull is painted using Awlgrip products or equivalent and using the lacquer finish procedure "TOP

YACHT".

This procedure is divided up into several phases whose implementation meets the Superyacht quality standard and is permanently controlled (temperature, hygrometry, ventilation, cleanness, thickness).

The final acceptance of work is made after control of the following criteria :

- Application : dry film thickness of each coat will be in line with manufacturer measurements. average thickness shall be not less than 80% and not above 150% of the recommended thickness.

- The topcoat shall be free of surface deficiencies and defects like runs, sags, fisheyes, pinholes, leaning marks etc. Small runs and sags are accepted in low visibility areas.

- Gloss measurements : Glossmetre method. Minimum average 87% at 60Åãon horizontal surfaces. Minimum requirement for vertical surfaces is 90% at 60°.

- Dust : maximum of 5 particles per square decimetre. Maximum of 10 particles per square decimeter in low visibility areas.

- Orange peel : surface texture – topcoat must have a uniform appearance with little or no difference in texture and giving a clear reflection of images.
