Already a solo round the world record holder, the trimaran MACIF has been thoroughly optimised by CDK and Keroman Technologies. The scope of intervention by the yard proved to be both dense and highly technical and have all been possible thanks to the close collaboration between CDK’s design office and that of MerConcept. Indeed, since the construction of the trimaran MACIF in 2015 by CDK and Keroman Technologies, the level of confidence and cooperation with the MACIF technical team has been exceptional.
Project manager Stéphane Digard and his team, who know the architecture of the trimaranMACIF inside out having built her in 2015, launched this extensive and complicated operation, which consisted of transforming part of the floats, and the structure accommodating the foil casings in particular, ready to host a new pair of foils manufactured by CDK Technologies, along with new rudders. At the same time, a new, lighter sandwich boom was manufactured in Port-La- Forêt, which resulted in significant weight saving. Between the design offices and those operating at CDK and Keroman Technologies, fifteen or so people rallied together in all to complete the refit.
Stéphane Digard explains: “Inevitably there is some complexity involved as the aim is to optimise MACIF as much as possible, whether it’s in terms of weight or performance. That said, it’s a boat we built so we’re very familiar with her. The real constraint was linked to timing as the boat had to be relaunched in late July to enable François Gabart, skipperof the trimaranMACIF to get out on the water before the Route du Rhum. There are always an enormous number of ideas and the hardest thing is to put them into practice whilst sticking to the delivery schedule.”
