[quote=bradinjax][quote=pairajacks]The question is what happens when your mast bends far beyond the point where the sail flattens out. My unerstanding is that if the cut of the main is 3 inches off vertical at the top, then the mast bend to flatten the sail would be 3 inches. What happens to the sail performance when your mast too easily bends to 8 inches?[/quote]
When too much (or too little) mast bend occurs you are at less than optimum trim for that given mainsail shape. There would have to be some force applied to make the mast bend past the cut of the luff curve. This could be any combination of diamond wires, downhaul (cunningham), Mainsheet, or even too much rig tension.[/quote]
