How PROSPERO compares with a typical Elan 310

Her main 2026 measurements against the middle of the fleet: one boat per sail number, the latest full-crew configuration with spinnaker, Elan 310s measured since 2025.

Above the line she is quicker than a typical Elan 310; below, slower. Move the wind: plenty of boats sit on one side in the light and the other when it blows.

True wind
