Fear of Heeling
Look at it from the perspective of the wife of a guy who just bought his first sailboat. She goes out with him on the boat and it heels to an angle of 25 degrees. Common sense tells her that when something leans over that far, it is about to fall over. Hubby assures her that everything is o.k., but she knows that he is just learning to sail, and, even though he thinks he''s an old salt, she knows he''s just an old windbag. She has no confidence in either the boat or the skipper. To dispel her fear, you have to prove to her that the boat is not going to fall over, and that the skipper and crew can control it.
I think 928 frenzy has the right idea. He took the wife out with an experienced instructor, who was credible to the wife, who showed her how stable the boat was, and who showed her how she and hubby could control the angle of heel. Her fear was displaced by knowledge.
Go sailing, and when the boat heels to an extent that makes you uncomfortable, ease the mainsheet. You will soon realize that you can control the extent to which the boat heels, and you won''t fear what you can control.
