How MAD X compares with a typical X-41

Her main 2026 measurements against the middle of the fleet: one boat per sail number, the latest full-crew configuration with spinnaker, X-41s measured since 2025.

Above the line she is quicker than a typical X-41; below, slower. Move the wind: plenty of boats sit on one side in the light and the other when it blows.

True wind
Upwind+0.05 kn
Beam reach-0.03 kn
Broad reach+0.25 kn
Downwind+0.20 kn

Full width is 0.8 kn either way.
