How GEM compares with a typical X-50

Her main 2026 measurements against the middle of the fleet: one boat per sail number, the latest full-crew configuration with spinnaker, X-50s measured since 2025.

Above the line she is quicker than a typical X-50; below, slower. Move the wind: plenty of boats sit on one side in the light and the other when it blows.

True wind
Upwind+0.25 kn
Beam reach+0.06 kn
Broad reach-0.03 kn
Downwind-0.03 kn

Full width is 0.4 kn either way.

At 10 knots she is quicker than a typical X-50 on the upwind.
