I have now sailed The Princess in the 15 - 20 wind range and she is a changed girl. She is not the stiff old girl she was and is definitely over powered with the 150% in that range. I don't think I would recommend pulling out the compensator ballast to you San Francisco Bay fellas or others on big water and in big wind. I'm still deciding if I like the change and will wait to add some weight back in with another battery bank until I settle on a new sail plan.
