HULL CONSTRUCTION

Yacht's hull is made by composite manner. Main framing is made from wooden battens with section 30x30 mm. Batten shape allows to assemble all the yacht's plating in lock
(see picture 1).

Hull plating is covered with 4-5 coatings of fiber glass using reinforced epoxy resin type of ED20 with total thickness - 5.5 mm. The total plating thickness is not less than 35 mm.
The given thickness ensures the strength and the lightness of the hull. This construction corresponds to German Lloyd's Register requirements.

The framing consists of:
- Cross framing with frames made from pasted oak battens 10x45 mm. The total frames section 40x65 mm.
- Main bulkheads with the pine timbers installation 100x50 mm which covered and pasted with water resistant plywood, 10 mm thick. The total thickness of main bulkheads is 70 mm.
- Beams made from pasted oak battens with total section 40x40 mm.

and brackets.
- Floors are made from oak timber with variable sections and are used as keel bar bed. The dimension at the foundation area is 120 mm.
- The special frame made from non-corrosive angles with the wall thickness 4 mm (see the picture 2).

The keel envelope is made of stainless steel and filled with the lead ballast. The total keel mass is 3.6 t. The keel is connected with keel floors by using 24 pins made of stainless steel with diameter 22 mm. Keel shape is showed on the picture 3.

The present connection was successfully tested by many yachts and never caused any problems. The connection of the main engine is carried out by same manner with help of floors system and metal frame (see the picture 4).

After many trials of the real yachts we came to classic yacht's lines which are used in the given project. Original tests of this project gave the following results:
