Also check your dolphin striker. The bolt holes on either end corrode and move sideways. Under load a little beam sag can allow a surprising amount of "mast rake". Maybe the mast ball is stripped out too (Sunlight can really tear them up and make them chew away suddenly) I think chronic hull deflection would be evident under load. Beam deflection is less visible from the wire. It also leads to beam cracks at the hull saddle, so check you have a bind on the striker. "unscrew" the post under the ball to tension. Don't know a setting (well actuallY I do - you TENSION IT SO THAT WHEN YOU SLAP IT JUST SO IT KIND OF MAKES LIKE THIS - YEA.) Somebody help.
