KH, not all the B&R rigs from Hunter were backstay-less. The early masthead versions had normal backstays, and even up to the mid 90s the fracs had a conventional backstay too.
It does sound like the OPs rig is ridiculously loose - and he does indeed need the services of a rigger as you suggest.
Yeah, I quit reading before I got to the part where he mentioned the backstay. Some of the older hunters had a traditional rig and you're right, most of the older B&R's had backstays too.
I was mostly concerned about the fact that he doesn't know how to add a wrap or two of furling line on the drum or a wrap or two of the sheets around the sail and the fact that he is getting halyard wrap with a Pro-Furl. The Wrap Stop should prevent that from happening as long as it's installed correctly and the halyard is tensioned.
It really sounds like he could use some instruction.
