The purist's choice
Classic Rig
Smart sailing. Finally available.
ACC Wing
The Ipsum was designed from the ground up around two distinct sailing philosophies, as we believe these represent two fundamentally different ways of experiencing the sea.
At its core, the innovative design features a broad mast placement, offering unparalleled adaptability to an extremely wide range of sail configurations and propulsion systems. This flexibility empowers sail designers and riggers to fully exploit the platform and deliver the best of their craft. What's more, the Ipsum can accommodate new sail plans, making it truly future-proof.
The purist's choice
The Classic Rig
A Pogo 40 S4 aero pack. On a trimaran that skims.
The Classic Rig is the one you already know how to read. A high-performance fractional setup, inspired by the offshore racing world, with an off-the-shelf sail inventory you can source, repair, and replace anywhere in the world.
It is immediate. Tactile. Honest in the way that only a conventional rig can be. You feel every shift in the wind through the sheet in your hand. You trim, you adjust, you make decisions. The boat responds. There is a direct conversation between you and the conditions that no automation can replicate.
For the purist, the solo sailor, the one who wants to feel everything: this is the setup.

The ACC Wing
The ACC Wing is a thick-profile cambered wing sail developed by our partners at ACCWing. The technology works on the same aerodynamic principles as an aircraft wing — thick, cambered, optimised. The result is a system that generates over 50% more drive than a conventional sail at equivalent surface area, with dramatically reduced drag.
The camberers work through the contraction of textile muscles that flex the battens. Light, supple, reliable. The wing rotates around a freestanding mast, adjusts its camber continuously, and in automated mode, responds to gusts in real time without any human input. It is not a traditional sail. It is closer to a wing you happen to be sailing with.

What it actually changes on board
Upwind, it points.
The thick cambered profile generates a level of upwind drive that conventional sails simply cannot match. You point higher than most monohulls. You sail out of narrow channels under sail alone.
Downwind, it flies.
Unroll the gennaker and the combination becomes something else. The ACC Wing provides a booster effect at the head of the sail. The boat accelerates. The apparent wind builds. You're surfing.
At night, it works for you.
The automated trimming system adjusts the wing continuously, absorbing gusts, optimising airflow, covering miles while the crew sleeps. Average speed climbs from 50% toward 80% of potential.
Short-handed, it is safe.
When you're sailing as a couple or with a small crew, everyone on board needs to be able to handle the boat alone if it comes to it. With the ACC Wing in automated mode, managing the rig is closer to driving a car than sailing. It adjusts itself, so you can focus on what matters.

Loic's take. If it were my boat.
We get asked this a lot. Here is the honest answer.
My racing background makes a pure 4-ton weapon with a Classic Rig and a full offshore sail inventory genuinely tempting. Lighter, cheaper, proven. You can fix it anywhere in the world. There is a tactile thrill in trimming a high-performance conventional plan that I genuinely love.
But I would still go with the ACC Wing. Here is why.
The man overboard factor.
We rarely sail with large crews. Usually it is just my wife and me. If I go overboard, she needs to be able to execute a rescue. With the ACC Wing in automated mode, managing the boat is as simple as steering a powerboat. That single factor changes the risk profile of every offshore passage we make.
The pointing.
Nothing is more frustrating for a multihull sailor than losing a pointing battle to a monohull. The thick cambered profile of the ACC Wing changes that completely. Sailing upwind out of a narrow anchorage under sail alone, without touching the engine, becomes normal. For me, that is close to the holy grail.
The 24/7 performance.
I have watched this with many boats over the years: even the best setups often perform at 50% of their potential because the crew wants to eat, sleep, or simply be comfortable. The ACC Wing absorbs gusts and optimises itself while you're off-watch. Your average speed stays high without the adrenaline spikes.
The vision.
The Ipsum was not designed to be just another trimaran. It was designed to be the perfect platform for this wing. The two belong together. That is not marketing. That is how we drew the boat.
Whichever rig you choose, the Ipsum's structure is designed around the ACC Wing or classic rig. The mast position, the load paths, the deck layout. Nothing is an afterthought.
If you start with the Classic Rig and change your mind in two years, the boat is ready.
