How ATAO compares with a typical Archambault 31

Her main 2025 measurements against the middle of the fleet: one boat per sail number, the latest full-crew configuration with spinnaker, Archambault 31s measured since 2025.

Above the line she is quicker than a typical Archambault 31; below, slower. Move the wind: plenty of boats sit on one side in the light and the other when it blows.

True wind
Upwind+0.06 kn
