Hi Rockyglen
Just wanted to help calm any fears of flying an asymmetrical sail such as the APC or UPS on a boat with a B&R Rig. We have been supplying these sails to Hunter owners for many years, and I personally have not heard of any B&R rigs coming down from flying one of these sails. The B&R rig is designed to be used without a backstay because of the swept back spreaders. Lars Bergstrom (Rest his soul) designed these rigs to withstand alot more abuse than a standard rig with a backstay. And I'm sure if there were any real fears or substantiated mishaps, Hunter would abandon these rigs. Most rig failures on cruising boat, no matter what kind of rig, are usually the result of improper tuning or lack of maintenance.
