Ambitions of the Multi70 Edmond de Rothschild

News - 4/24/2015

In refit since her return from the West Indies back in December, the Multi70 Edmond de Rothschild left the cosy atmosphere of her technical base in Lorient this Wednesday morning to return to the liquid element. Benefiting from the first tide of the day and the summery weather, it didn’t take long for the members of Gitana Team to release the carbon machine, which is now safely tied to the dock at the Keroman submarine base.

This launch is synonymous with the start of phase two of a project initiated in early 2014 by the team created by Baron Benjamin de Rothschild: namely the mission to make the Multi70 the first flying trimaran on the offshore racing circuit.

An adventure in two chapters

Back in 2014, true to its philosophy, the team created in 2000 by Baron Benjamin de Rothschild paved the way by opting to kit out its 70-foot trimaran with lifting surfaces on the float rudders. The aim at that time was to participate in the 10th edition of the famous Route du Rhum and hence cross the Atlantic singlehanded. It was a bold challenge! Indeed, besides the technical development required by such a project, on the water the human commitment was significant since Sébastien Josse would have to compete against the giants of the Ultime class; the largest of which measured twice the size of the Multi70...

A 70-foot test laboratory

The forms below the waterline, the size of the floats… at first glance, the Multi70 Edmond de Rothschild is the same boat as that which set sail from Saint Malo last November in the Route du Rhum! Indeed, true to its initial plan, the team opted to adapt the original platform, even though the latter has undergone some structural reinforcement. However, the 2015 version has a host of new features if we look more closely at the appendages.

The first of these relates to the aft section of the floats where the T-foil rudders, the principle of which was tested and validated in the Rhum, have been scaled up: “The rudders have been extended both along the vertical section and the lower section. We’ve had new rudder elevators made so as to increase the surface area of the foils. The latter elevators are twice the size they were last year, which is essentially to balance out the platform following the added foil volumes,” explains Pierre Tissier, Technical Director of the five-arrow stable.

The Gitana Team seeing double in the Tour de Belle-Ile

Though tomorrow will see the first of a series of training sessions for Sébastien Josse and his men off Lorient, south-west Brittany, the 70-foot trimaran will have to wait until 9 May and the Tour de Belle-Ile for her official return to the racing circuit. This 42-mile sprint around the Morbihan-based island, amateurs and professionals combined on the same start line, is the biggest sailing gathering in France with over 400 yachts expected to compete, so it is no surprise that it has become a classic meet for the Gitana Team. This year, the team with five arrows has even chosen to enter two of the craft fitted out by Baron Benjamin de Rothschild; two platforms whose common denominator is flight! (...)
