With the Ipsum 45, AWA (Apparent Wind Activities, or Analysis - Architectures - Agency - Associates - Apparatus - Activities...) is not proposing yet another trimaran in the fast multihull category, but a nautical object built around a unique principle: that of an open boat, evolving and not set in stone as soon as it leaves the yard.
A trimaran designed as a base rather than a finished product
The starting point of the project is a Core Kit, in other words a limited set of critical structural parts. Hulls, load-bearing elements, key technical areas - everything is dimensioned and produced to ocean racing standards.
But the rest of the boat escapes strict definition. The owner is directly involved in the choice of construction, materials and fittings. This positioning contrasts with production trimarans, which are delivered ready to sail with fixed configurations.
For the yachtsman, this implies a strong commitment from the outset. The boat becomes a project in its own right, and not just a purchase.
A freedom of construction that impacts behavior at sea
This structural choice is not limited to aesthetics or layout. It has a direct influence on navigation characteristics.
The displacements, inertias and stresses in the structure vary considerably between a lightweight carbon composite version and one incorporating epoxy wood. This means that two Ipsum 45s can behave differently downwind and upwind.
This parameter is of interest to experienced sailors, able to adjust the boat to their program. On the other hand, it complicates the usual reference points for those looking for a standardized platform.
An à la carte rig that redefines maneuvering
The same principle applies to the sail plan. The choice between an automated rigid wing and a conventional rig is not simply a level of equipment, it's a navigation orientation.
The wing profoundly changes the way the boat is managed. The settings change from a textile sail logic to a rigid lift logic, with gains in aerodynamic stability but also constraints in operation.
The classic rig, on the other hand, maintains a more direct reading of stress and balance. It remains compatible with committed sailing and repairs during stopovers.
This dual choice illustrates the logic of the project, which is to let the navigator decide on his or her relationship with performance and complexity.
Livability designed as a modular space
The trimaran's interior follows the same philosophy. The linking arms become usable volumes, capable of accommodating a variety of modules.
Whether loft-style cabins, storage areas for nautical equipment or specific layouts, each configuration is designed for a specific use. The boat can thus evolve from a sports cruising program to an activity-oriented platform.
This approach changes life on board. Volumes are distributed differently from the norm, with areas that are more exposed but also more open to the outside world.
An approach aimed at an informed public
This radical choice is not intended to simplify access to multihulls. It is aimed at sailors who want to master their sailing tool, right down to its design.
The link with the world of ocean racing is found in this logic, where every detail counts and the boat is built around a precise program.
Ultimately, the Ipsum 45 does not seek to meet an existing demand. It offers a technical framework within which each owner can define his or her own trimaran, with the advantages and constraints that this implies once at sea.
