Months of preparation go into every offshore campaign, but sails are always at the heart of success. At Quantum, our work goes far beyond simply building sails: we bring together a global network of designers and sailors whose knowledge is shared, tested, and passed on to the next generation. Every inventory is the result of true collaboration, crafted alongside the sailor to meet the unique demands of their boat and their race. Nowhere is that more evident than in the Mini Transat, a race where our team's collective experience truly shines.
For Alicia de Pfyffer, preparing to sail solo across the Atlantic in her 6.5-meter boat Little Wallaby, that knowledge has been key. Behind every tack and trim lies a carefully crafted sail plan, developed in collaboration with Quantum's Gildas Dubois. A seasoned Mini sailor himself, Gildas has logged countless miles in the class and brings a deep understanding of what it takes to finish the race. "The Mini Transat presents unique challenges that require an expert's guidance," explains Quantum's One Design Director, Scott Nixon. "Quantum is lucky to have Gildas as our sail designer and class expert in the Mini. He has logged many personal miles in the Mini and has worked with some top teams over the years that have honed his expertise."
And while Gildas has been central to Alicia's sail development, he is far from alone. The insights of Quantum experts like Yannick Lemonnier and Jelmer Bouw add another layer of depth, ensuring Alicia's sail inventory reflects not just one sailor's perspective, but the combined experience of a team that knows the race, the boats, and the demands of solo offshore sailing.
Quantum Sails Ireland's Yannick, who has crossed the Atlantic three times and logged nearly 100,000 offshore miles, explains that the Mini Transat is as much about preparation as it is about endurance. "There are no shortcuts; you have to practice, test your sails in every condition, and make changes where needed," he explains. "With only a limited number of sails allowed, you don't want too much overlap. Every sail has to cover its range, and the designer's role is critical in getting that balance right."
For Alicia, the project with Quantum represents the blending of ambition, experience, innovation, and a partnership designed to carry her across the Atlantic in one of sailing's most iconic proving grounds.
THE RACE
Before we start with the sails, let's look briefly at this unique, challenging race.
The Mini Transat is a race unlike any other. Sailors navigate without support or modern communications, relying entirely on their skills, strategy, and resilience. For Alicia, a talented young solo sailor full of energy and determination, it's not only the adventure of a lifetime but also an opportunity to continue breaking barriers in a sport where women remain underrepresented. The 2025 edition of the Mini Transat will start in Les Sables d'Olonne, France, with the first leg to the Canary Islands, and then across the Atlantic to Guadeloupe. The route packs in a brutal mix of conditions. "During the first leg, you usually cross a weather front in the Bay of Biscay, which is tough," says Gildas. "The seabed drops steeply, so the waves get very rough—especially for a smaller boat. You need strong upwind sails to manage that. The second leg is longer and mainly downwind in the trades, which is why the Mini 6.50s are built for big kites and planing conditions."
THE SAILS
THE PROCESS
While innovation continues in offshore racing, the Mini 6.50 class rules keep sail technology in check. "Exotic materials are only allowed for Prototypes," Gildas explains. "Series boats can only use dacron for mains and jibs, polyester laminate for gennakers, and nylon for kites. It's partly about budget, but also about durability and ecology, which will push the market to make things differently."
"Working with Alicia has been very collaborative," says Gildas, an authority on one design offshore sailing and the Mini Transat in particular. "She brings her perspective as the skipper, and I bring my experience from racing the same boat for two seasons. Together we've been able to make smart choices about which sails will give her the right balance of performance and reliability for the race." One of those key decisions was between a cable-less A0 and a G0 with an AT cable for Little Wallaby's Code Zero. "After discussing the options, we decided on the G0 because it's easier to use singlehanded, which is critical when she'll face squalls, sail changes in the dark, or long stretches relying on the autopilot."
"This was the first time in my career that I've had the opportunity to work so closely with a sail designer, and it's been an incredibly valuable experience," adds Alicia. "It's fascinating to gain a deeper understanding of the reasoning behind Gildas's design choices, and to see the different philosophies compared to my previous sails…Overall, I'm very happy with the process and results so far, and I'm excited about the potential for bigger projects in the future.
THE INVENTORY
Mini Transat sailors are limited to just six sails, which forces them to make tough choices in covering the full wind range and sailing angles. "The Mini class—like other one-design classes—has strict class rules, sail limitations, and certain restrictions that must be followed in detail for the sails to measure in and meet the challenges of the long race," says Scott. "Our designers, production team, and reps work together to make sure our sails are up to the one design standards. We are so excited Alicia chose to work with us and are rooting for her in next month's start." Alicia's sail wardrobe will include:
- Mainsail with three reefs
- AP Jib with one reef
- Storm jib with one reef
- Code Zero (G0)
- A3 (heavy/medium spinnaker) with a reef
- A2 (medium/light spinnaker)
The sail plan also reflects the demands of the Mini Transat course. The opening leg from France to the Canary Islands can mean tough upwind sailing in heavy seas, requiring a versatile mainsail with multiple reefs and a reliable jib. By contrast, the second leg toward Guadeloupe is dominated by downwind trade-wind conditions, where big kites become essential for speed and endurance. "The race is really two different challenges," Gildas explains. "You need strong, dependable sails to survive the first leg, and then durable, fast downwind sails to carry you thousands of miles across the Atlantic."
Here's how we approached her inventory and where we focused:
SPINNAKERS
Because the race is predominantly downwind, the spinnakers are critical. "You need to be sure the downwind range is properly covered," Gildas explains. "We added a reef to the A3 so it can double as a fractional heavy kite. And if there's an issue with the A2, you can unreef the A3 and still finish with a solid downwind sail. Reefs are a way to make sails more versatile."
BALANCING WEIGHT + DURABILITY
Durability is also a major consideration. "It's offshore racing, so you focus on strength, but you can't make the sails too heavy," explains Gildas. "These are lightweight boats, and performance remains the target. The balance between strong and light is always the hardest part."
EASE OF USE
Unlike fully crewed boats, solo racers rely on sails that can be handled quickly and consistently without extra hands. "Single or doublehanded sails need to be easy to use," Gildas says. "That means easy trim sails and stable kites because the skipper has to sleep a little, and the autopilot is never as good as a human helm. Fatigue is another factor. Sometimes you lose lucidity, so having sails that are simple and forgiving is important."
Small design details make a big difference: "The way you reef a kite, or the placement of a spinnaker bag attachment—everything has to be efficient," he adds.
RELIABILITY
In the Mini Transat, durability means sails that can withstand weeks of relentless ocean stress without failing, while reliability means sails that perform consistently as designed, giving sailors confidence that every hoist, reef, and trim will deliver the response they expect. "Life onboard is full-on. It's a constant balance: the pressure of competition, navigating and reading the weather, making sure you're rested and fed, and keeping the boat in one piece—all while trying to sail as fast as possible," adds Quantum Sails Netherlands' Jelmer Bouw. "Having a reliable set of sails makes a huge difference. They give you confidence and peace of mind when your attention is pulled to all the other tasks onboard."
