The structural design of the hull has been RINA approved. This guarantees the structural quality which is enhanced by the use of innovative materials and technologies. The hull and the deck have been built using infusion techniques. Conventional techniques have been used for the deckhouse. The flybridge has been built using infusion techniques from series 115 onwards. Bow and stern, engine room and crew quarters trays: these are structural trays made using infusion technology (first 2 series made using manual techniques). Fibreglass structures with use of multiaxial fabric with a powder binder and carbon fibre on the flybridge. Neopentilic and isophtalic spray gelcoat. PVC foam is used for the sandwich panels on the hull, deck and superstructures. The bow collision engine room bulkheads are made of structural wooden sandwich. DCPD resin has been used in the inner layers of the hull and superstructure. Vinylester resin (resistance to osmosis and print through marking) has been used for the external coats of the hull. On the strength of these characteristics, AZIMUT is able to offer a 5-year warranty against osmosis. Planing keel with deadrise of 15.6° at the stern and 22.5° amidships.
