Thanks folks - for the replies so far!
I didn't know you could fit anything but a 'Junk' with junk rigging - or that it was as versatile as timmynocky tells me. It just looks odd to me - but hey - keep all options open!
I'm learning about furling systems, and I think I understand most of what they're about, but I still wonder about self-tending and club footed foresails. Can they be combined with furling systems? and does anyone know if they work with a cutter like a Tayana 37?
Thanks again for the responses!
