How JUMBO JET compares with a typical J/105
Her main 2026 measurements against the middle of the fleet: one boat per sail number, the latest full-crew configuration with spinnaker, J/105s measured since 2025.
Above the line she is quicker than a typical J/105; 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 is quicker than a typical J/105 on the broad reach.
