AC-1 VS AC-3 NEW SAIL SIZES

You might have noticed several new sizes in our Racing sail range, positioned between the AC-3 and AC-1.

The AC-3 is essentially the same as the AC-1, but with a smaller mast sleeve. This results in reduced power and drive compared to the AC-1.

What does this mean in practice?

The AC-3 has been developed to require less physical effort and professional-level fitness to use its performance at 100%. The AC-1, on the other hand, delivers maximum power for ultimate drive and acceleration, but only if you can control and transfer that power efficiently to the fin.

If you can handle it, the AC-1 offers the highest performance available on the market. If not, that extra power becomes ineffective weight. You will tire faster and may actually perform worse than on an AC-3.

On the water, the AC-3 feels lighter, not because of its actual weight, but due to its reduced drive. This allows the board to fly with less effort, especially on a beam reach or upwind. Jibing is also easier, as the sail requires less input when the cams rotate to the new tack.

New Sizes Explained

Both models now include the new 8.2, 7.3, and 6.5 sizes.

These sails are based on the same designs as the 8.8, 7.8, and 6.8 respectively, meaning identical mast length, luff, and profiles. The only change is a slightly narrower outline.

This results in:

• Shorter boom length
• Reduced back-hand pressure
• A lighter overall feel

These sizes are particularly suited to lighter riders.

For example:

• A rider over 80 kg would typically choose an 8.8 for light wind, benefiting from the longer boom and added power to drive the fin.
• A rider under 80 kg would be better suited to an 8.2, which still uses the same 490 mast, retaining power, but with less pressure on the fin as wind increases, making it easier and more efficient to ride.

The shorter boom also provides better release, allowing for higher speeds with less effort. While heavier riders achieve this by pushing harder on longer booms, lighter riders benefit from a more efficient setup.

Our Recommendations

• 78 to 83 kg: Choose based on personal preference
• Over 80 kg: 8.8 / 7.8 / 6.8
• Under 80 kg: 8.2 / 7.3 / 6.5

For smaller sizes, 5.9, 5.4, 4.9, both weight groups can use the same sails.

Why There Is No 8.8 in AC-3

To make an 8.8 AC-3 effective in light wind, the mast sleeve would need to be wider to maintain proper balance. At that point, it makes more sense to either:

• Use the 9+ for an easier freerace light wind option
• Go directly to the 8.8 AC-1

No unnecessary marketing sizes, just real performance choices.

There are also rumors that racing may introduce weight divisions next year, so choosing the right size now could be important.
