How THETIS I compares with a typical Oceanis 400

Her main 2026 measurements against the middle of the fleet: one boat per sail number, the latest full-crew configuration with spinnaker, Oceanis 400s measured since 2025.

Above the line she is quicker than a typical Oceanis 400; below, slower. Move the wind: plenty of boats sit on one side in the light and the other when it blows.

True wind
Upwind+0.03 kn
Beam reach+0.00 kn
Broad reach-0.09 kn
Downwind-0.07 kn

Full width is 0.4 kn either way.

At 10 knots she gives away time to a typical Oceanis 400 on the broad reach.
