New radical trimaran based on modular principles
The Ipsum 45 trimaran achieves a unique fusion between DIY philosophy and the radical engineering and technology of modern ULTIM trimarans.
The trimaran is designed by AWA design studio and deliberately does not follow modern day trends. Instead it echoes the organic curves that defined the legends of the 70s and 80s and the iconic trimarans of that era.
However beneath the semi-classic exterior lie hulls designed by Guillaume Verdier that are optimised with sophisticated simulation tools (CFD) and ‘skimming’ foils that promise speeds once only imagined by trimaran pioneers.
The ‘skimming’ effect works using ‘winglets’ that lighten the floats and dampen their motion, providing a smooth glide.
The AWA team is keen to point out that the Ipsum 45 is not a production trimaran, instead it’s a canvas waiting to be filled with the owner’s ideas.
The starting point is the Core Kit – a limited set of structural components and the remainder of the boat is designed by the owner, with a large number of modular options.

These range from full-carbon construction with aero-fairings inspired by the latest ULTIM, to builds utilising wood-epoxy finishes, potentially adorned in a historical yellow.
Choose from the ACC Wing Sail, a self-supported and automated wing, or the Classic Rig (Inspired by the Pogo 40 S4), with an offshore racing aero pack and off-the-shelf sails readily available on the market.
Internally, structural cross-beams are integrated into the boat’s aerodynamics, allowing space for either one or two loft-styled cabins or there’s also the option for a traditional double-beam and trampoline setup.
AWA (Apparent Wind Activities, Analysis - Architectures - Agency - Associates - Apparatus – Activities) wants the owner to be directly involved and to form a commitment from the start of the build.
As the yard says, by merging classic design and technological breakthroughs, Ipsum offers vessels that are worlds apart from mass-produced boats and standardised option lists.
