Thanks, just found the earlier thread that included what I wanted to know om Wouter's proposal.
I'll have to put some more thought into that - hadn't factored in the effect a trapeze could have on sail shape on an unstayed mast.
I was told that the trapeze lines would be attached to tape reinforcements sewn to the sail sleeve. Use of the trapeze bends the mast to windward and back and this must be considered when making the sail.
