How NIMROD compares with a typical JPK 39
Her main 2026 measurements against the middle of the fleet: one boat per sail number, the latest full-crew configuration with spinnaker, JPK 39s measured since 2025.
Above the line she is quicker than a typical JPK 39; below, slower. Move the wind: plenty of boats sit on one side in the light and the other when it blows.
Full width is 0.4 kn either way.
At 10 knots she gives away time to a typical JPK 39 on the upwind.
