You are sort of describing the system I have but the real problem is not in the uphual and the outhaul but the retrieval line, we need to figure out a way to get that 1:2 to equalise things out a bit plus its getting the spinnaker down quickly enough to prevent the sheets going undr bows etc.

By the way what is the convention 2:1 or 1:2 for a rope that pulls 2 metres for every 1 metre it is pulled ?
