Alinghi: AC Catamaran Building Photos

Rolf Vrolijk, chief designer: “People who see the boat for the first time seem surprised at how light and fragile it looks, that is really their first impression. Creating it has been a huge team effort, both in the design and the build groups; it has been a phenomenal team effort to come up with the concept and it really represents the depth of our team. For the moment we have pushed the envelope as much as we would like, this boat is really a base for further development and over the coming weeks we will collect as much information as we can and cross check it with the predictions, this will help us assess what level we are at and then to optimise from there. We have several opportunities and possibilities to change the concept but first we need a solid base to do our studies from.”
Murray Jones, strategist and design team responsible for mast and rig programme: “This multihull is nothing like you’ve ever seen before in a big boat. It’s like a small boat but scaled up. It’s a highly finely tuned and engineered boat that’s light. It’s a piece of art. Alinghi 5 has evolved from the Swiss sailing boats, like the 41ft ‘Le Black’. The basic engineering concept has come from ‘Le Black’ but everything else has come from the Alinghi design team, starting from a completely blank sheet of paper, with no preconceived multihull ideas. We started designing it and building it and we’ve done a lot of sailing and testing on ‘Le Black’ and the Décision 35s so we’ve incorporated some of the ideas we’ve picked up sailing these boats.
