The 2027 1D Falcon wins the Spanish A-Class Championship 🥇

The 2027 1D Falcon A-Class mainsail has made a winning debut, taking victory at the Spanish A-Class Championship in the hands of Emil Järudd.
The Falcon is the latest development in our A-Class range, created for the 2027 season with an updated shape and refined profile. As with every 1D racing sail, the goal is simple: to deliver a sail that is fast, efficient and easy to control across a wide range of conditions.
Its first major championship result could hardly have been better.

Seeing Emil Järudd win the Spanish title with the new Falcon is an important milestone for us, and a strong confirmation that the development work behind the 2027 design is moving in the right direction.

Winning from the start.

🏆 F18 Americas Champions!

Charles Froeb 🇺🇸 and Pablo Völker 🇦🇷 are the 2026 F18 Americas Champions, racing their Nacra Evolution with 1D Sails.

After a challenging start to the championship, Charles and Pablo found another gear when the breeze came in, scoring three bullets and a second place in one day, taking the overall lead and securing the title on the final day.

A fantastic result for the team and another major F18 title for 1D Sails.

Congratulations Charles and Pablo! 👏

Catamaran sailmaking is one of the highest levels of sailmaking.
The margin for error is incredibly small.

High-performance catamarans are fast, highly loaded and extremely sensitive to changes in sail shape, rig setup and trim. Nothing works in isolation: sail, mast, rig, platform, foils, crew and the way the boat is sailed all influence each other.
That is what makes designing and building catamaran sails so demanding.

A sail has to deliver the intended flying shape under real loads, while the mast bends and rotates, the platform deforms under load and the apparent wind changes rapidly with boat speed.
And experience teaches you something important:
not every millimetre matters equally.
The real skill is knowing which ones do.

That knowledge comes from years of designing, building, measuring, testing, racing and modifying, then validating whether the change actually made the boat faster.
F16, F18, A-Class and Tornado have been a major part of this development at 1D Sails for more than a decade.

We have tested that knowledge at World Championships.
Catamaran sailmaking teaches you to understand the whole system, not just the sail.

And that knowledge goes into every sail we build.

Great sails are not born from one idea.
They are built through development, testing, simulation, sailor feedback and real racing pressure.
This is why we are looking back at some of the key moments behind the 1D F18 Pro line, not for nostalgia, but because today’s sails are built on everything we have learned on the racecourse.

Another trophy for Manu Le Chapelier and Éric Le Bouëdec in the F16 class! This time at the French Championship, in what seems to have been one of the biggest F16 fleets ever.

For us, national championship victories matter a lot. These events bring together strong fleets, different sailing styles, changing conditions, and real pressure. A national title is not won in a perfect test environment, but on the racecourse, against sailors who know the class, know the boats, and know how to push hard.

That is exactly why results like this are so valuable for us: feedback and confirmation.
They show that the work behind the design, the materials, the cut, the details and the continuous development is going in the right direction.

We are proud to see 1D sails winning not only at international events, but also in strong national championships where consistency, speed and control matter race after race.

Congratulations to Manu and Éric, French F16 Champions.
Thank you for keeping our sails at the front of the fleet, since 2015!
