How JAM compares with a typical J/88

Her main 2026 measurements against the middle of the fleet: one boat per sail number, the latest full-crew configuration with spinnaker, J/88s measured since 2025.

Above the line she is quicker than a typical J/88; below, slower. Move the wind: plenty of boats sit on one side in the light and the other when it blows.
