2000 has seen the launch of the first Yacht of a series of fast cruisers by the Maxi Dolphin Yard in Erbusco (BS), Italy. Built in Advanced composites with shell skins in epoxy pre-impregnated carbon/glass/aramid fibres over a CoreCell core. Working in tight collaboration with the designer Luca Brenta and the yard, Trimarine has developed, for the production of this light displacement hull an innovative construction technique based on a male mould plug. Apart from it’s involvement in the definition and development of the construction process, Trimarine was responsible for the overall quality of the project and in particular, working in tight contact with the yard’s technical office, the construction follow-up and the fit out of the prototype collaborating in the choice of accessory elements and systems with the scope of containing the weights and also in avoiding any alteration to the aesthetic choices of the design team. After completion of the first prototype, we have been involved in the analysis of the construction data and in the subsequent optimisation for the series production.
