I was doing a occasional search for a used Baby Bob mast float. In a discussion about the baby bob on a 140 a guy mentioned he found the boat was more stable with the jib out but loose. He had furled the jib and went over. Can someone explain why? What is happening? I have read and think I understand why a boat that is not moving is more likely to go over. I am curious why keep in the jib but loosening the sheets offers a more stable boat.
