In theory, how fast does it go?
• This VPP study from Marc Lombard is for a loaded sailing displacement of 13,300kg, on flat water
• The boat speeds are calculated for a maximum heel angle limited to 7.6°. This is the angle at which maximum righting moment (RM Max) is achieved
• This value of heel angle corresponds to apparent wind speeds for each true wind angle and each true wind speed noted in the AWS table
• This VPP was calculated using The Wolfson Unit’s WINVPP with the necessary attention to all parameters

much as possible. Despite the quite large number of comfort options and equipment incorporated, the first boat is really light. We are already working with the architect to reduce the slamming in short seas and make it more comfortable with a more distributed weight alongside for a more cruising oriented programme, or by considering ballasts in forward hulls to be filled when going upwind, for more performance and racing-type programmes’. The position of the first reefing point needs adjusting slightly to improve tension in the foot, and Bruno adds this to his surprisingly short to-do list. The boat’s upwind VPPs seem attainable with some further fine tuning, and I have no doubt this team will get the boat set up perfectly for future clients. It is too early to accurately assess
just how fast this boat can be on the racecourse. The ORC42 and ORC50 have been stand-out performers in RORC multihull divisions in recent years, with both proving competitive under a range of multihull rating systems, and there is every reason to believe that the ORC57 will continue the trend. Broadly speaking the ORC42s keep pace with Class40s whilst the ORC50s keep pace with TP52s, so the ORC57 can expect to finish ahead of everyone bar the highest-level grand prix race yachts.
Interior layout I pass the helm to Eric Levet, here from Marc Lombard’s design office to help with testing, and head inside to check out the interior. The layout is fairly conventional for a multihull, with the bridgedeck living space enjoying 360° views and cabins in the hulls. There is a large forward-facing chart table with excellent visibility which would make a comfortable place to stand a chilly night watch whilst cruising. The L-shaped galley has a large oven, electric hob and Nespresso machine, whilst the lounge and dining area can seat eight in comfort.
Boat number one has the entire port hull reserved for an owner’s suite, complete with a large double bed, plenty of wardrobes, an office space, and an en-suite including a toilet, double sinks and a walk-in shower. There are two more cabins and another toilet / shower room in the starboard hull. It is easy to imagine living aboard on a semi-permanent basis during a multi-year round the world adventure, which is clearly the intention of some clients. A big effort has been made regarding
interior design, with the challenging brief to make the boat more comfortable without
