Multi 50

An efficient compromise

Bringing together older multihulls from the eighties corresponding to the Spirit category and newer prototypes specially designed for recent transatlantic races, such as Arkema, Multi50s offer the special feature of uniting skilled professionals and enlightened amateurs.

Following in the footsteps of the 60-foot Orma trimarans, these multihulls have however come up with simplified rules to limit costs, while offering a lot of freedom in terms of their overall configuration, whether we are talking about trimarans or catamarans. Exotic materials, such as honeycomb constructions are not allowed. Unlike the MOD70s and Ultimes, they don’t have foils or canting masts. There are no hydraulic systems, but the shape of the hull is left wide open, as is the way the four appendages and sails are placed, although the air draught is limited to 23.77 metres.

At the moment, the Multi50 class includes nine multihulls, the oldest of which (PiR2) dates back to 1983, while the most recent (Arkema) was built for the 2013 Transat Jacques Vabre. In spite of their size and limitations imposed by class rules, Multi50s are capable of reaching thirty knots and in terms of performance come between the MOD70 trimarans and the IMOCA monohulls…
