Last week two friends and I were sailing my 2000 H-260 on Lake Mead. We had winds blowing from 25 to 30 MPH. Out plan that day was to sail the boat hard as I wanted to know how it would handle when the winds were high. Well, the boat did well. We seldom got more than twenty degrees of list even though we were using full sails. However, we had a problem with the jib. No matter how tight we set the jib sheet, the jib continued to luff severely until we failed the clew of the jib. The metal ring pulled through the two straps holding it to the jib. How should we have trimmed the jib under these conditions? What could I have done to keep the jib from luffing so severely.Incidently we also failed two of the slugs on the main sail.
