How CHISUM compares with a typical Cape 31
Her main 2026 measurements against the middle of the fleet: one boat per sail number, the latest full-crew configuration with spinnaker, Cape 31s measured since 2025.
Above the line she is quicker than a typical Cape 31; 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 Cape 31 on the beam reach.
