Hull and Structure

HULL GENERAL

Hull form is designed on the basis of experience on previous similar Yachts, taking into account resistance, seakeeping and maneuverability characteristics.

The structural design and assessment is designated according to the most recent experience acquired by the Builder in design and construction of GRP for this type of Yacht and according to the RINA Classification Rules. The hull is divided into 3 watertight compartments, by the watertight collision bulkhead on the forepeak and watertight Engine room bulkhead, in accordance with Classification rules. The watertight collision bulkhead is positioned in accordance with the Classification Rules. A chain locker space suitable to contain both port and starboard chain cables are provided forward the watertight collision bulkhead.

HULL & DECK MATERIALS AND CONSTRUCTION

The Yacht has been constructed with a combination of sandwich and single skin GRP laminate using mat, unidirectional/biaxial E-glass/carbon fibers and closed-cell foam cores for sandwich, according to the structural drawings approved by the Classification Rules. A skin coat is made using vinylester resin to prevent osmosis of the inner laminate. Hull (both bottom and sides) and deck is made (mainly) of sandwich laminate by infusion process.

The hull structure is framed with main longitudinal structural members and transversal bulkheads, and secondary transversal structural members.

Fuel oil and black, grey, fresh water tanks will be integrated. Each tank have at least one manhole. Internal tank surfaces will be treated using vinylester resin as follows:

•  Fuel tanks: 2 C-glass layers

•  Fresh water: food grade gelcoat

•  Other tanks: 2 additional E-glass layers

The deck structure is made of longitudinal/transversal structural members and sup- ported by bulkheads.

Bulkheads are made of GRP sandwich and composite marine plywood. GRP bulwark is integrated into the hull sides.

The bulwark is equipped with fairleads, access doors and freeing ports, in compliance with the Classification Rules. A GRP bow thruster tunnel has been installed on the hull by proper lamination as well as watertight connections through watertight bulkheads.
