Foils Designed for Dynamic Lift Dictate the AWA Trimaran Build
Historical Inspiration and Modern Flow
The trimaran sector continually shifts between extreme offshore racing and long-distance cruising. Operating out of France, the AWA studio has introduced the Ipsum 45, a 14.20-metre project that merges the aesthetics of the 1970s with contemporary multihull engineering. Founders Loïc Goepfert and Julien Boucher drew inspiration from ocean-going vessels like Mike Birch’s Olympus to establish a sleek, classic silhouette. Beneath this traditional exterior, naval architect Guillaume Verdier utilized complex flow simulations to optimize the hull geometry for sustained offshore speed.
Developing the Skimming Effect
Achieving velocity on the water requires precise foil implementation. The Ipsum 45 deliberately avoids a full-foiling configuration, opting instead for small wings equipped with winglets attached to the floats. These specific foils generate a calculated skimming effect, providing dynamic lift to relieve the leeward floats during heavy transits. This architectural choice dampens aggressive movements in rough seas and reduces the maximum draught to 2.20 metres, ensuring the 4.0-tonne vessel glides smoothly rather than lifting entirely clear of the surface.
Structuring the Connecting Arms
Maximizing usable space on a multihull frequently forces a compromise in aerodynamics. AWA replaces narrow crossbeams and traditional trampolines with fully faired, walk-through connecting arms positioned between the central hull and the outer floats. This massive structural shift creates internal volume intended to house separately accessible living modules modeled after compact lofts. Buyers can configure these enclosed arms to include private bathrooms within the floats or utilize the port and starboard areas as dedicated storage for diving and wingfoil equipment.
Automated and Traditional Rigging Configurations
Propulsion systems dictate the operational profile of any sailing platform. The French studio designed the vessel to accommodate the ACC Wing Sail, an automated, self-supporting rig engineered to simplify handling while generating substantial aerodynamic lift. For owners favoring a conventional approach, the shipyard provides a classic rig option based on fast regatta layouts similar to the Pogo 40 S4. This flexibility allows operators to tailor the aerodynamic package precisely to their specific offshore requirements.
Decentralizing the Build Process
Establishing a highly customized platform requires an adaptable manufacturing pipeline. AWA structures the production of the 9.15-metre wide trimaran around a prefabricated core kit. Specialist suppliers manufacture the high-stress structural components, which are then shipped in standard 40-foot containers alongside the selected living modules. The final assembly and outfitting take place at a shipyard chosen directly by the owner, positioning the vessel as a distinct hybrid between a semi-custom yacht and a heavily managed DIY construction project.
