Construction

Hull

Hull and deck are constructed entirely in sandwich with PVC core (80 kg/cm) and in which the skins are made of multi-axial fabrics of e-glass impregnated with epoxy resin. The lamination is performed manually but with compaction under vacuum, which guarantees the security of a visual check of the correct impregnation of the fabrics and the optimization of the resin/glass ratio.

At the end of the construction the hull is subjected to the "post-cure" process; the hull is heated and maintained for 36 hours at a temperature of 60 Celsius degrees .

 

Structure

The  structure of reinforcements is made of marine plywood entirely laminated to the hull (NOT glued!) in order to avoid detachments also in the event of violent shocks, and  incorporates the fiberglass housing of the keel and the base of the strut that release the mast efforts.

The floor is done with a sandwich construction and is glued to the structure of reinforcements and welded to the hull so  to obtain a series of sealed compartments on the bottom of the hull from the bow up to the keel. These sealed compartments greatly increase the safety and in case of destructive collision with the hull breakthrough not allow water to penetrate inside the hull.

 

Bulkheads

All bulkheads are realized in sandwich with the same technique with which is made the hull for maximum rigidity and lightness. The bulkheads are laminated to the hull, the internal structure and the deckwith glass fabrics and epoxy resin.

 

 

The deck

The deck is entirely built in sandwich with PVC core just like the hull.

And it's glued to the hull (which has a wide flange) with epoxy structural adhesive and then welded externally by a  lamination with glass and epoxy resin to achieve a monolithic joint.
The hull and deck are finished with gelcoat; on the deck and the walkable areas is applied  an anti-slip surface.

 

Chainplate

The side and the stay chain plates, are made of carbon fiber laminated to the hull for maximum strength and good homogeneity of materials.

 

The keel

 

The keel has a "T" profile with a full steel blade and a lead bulb, all enclosed in a fiberglass epoxy cover that creates a monolithic object in which the metals are completely isolated from the sea.

The end of the keel blade is milled to have a truncated pyramid profile. On the head of the keel is molded a fiberglass housing made of glass, carbon and epoxy resin, which is then positioned on the hull and welded to the bottom and to the monolithic structure of the reinforcements.

 

The rudders

The rudders are made of e-glass fabrics and epoxy laminates using a female mold. Inside of the rudders it is casting a special epoxy resin foam  which guarantees the perfect structural adhesion between the rudder and the shaft and the impossibility of infiltration of water even with large thermal excursions. The shaft is made of high resistance stainless steel AISI 630 (also known as 17-4 PH).

We suggest tu install tillers for the maximum simplicity and sensitivity, but optionally  wheels can be mounted. The shaft are mounted on Jefa self-aligning bearings at both hull and deck to compensate the  downturns caused by high speeds when the boat plane.
