What I have now is a is a single line system with no purchase. I cannot adjust it when under load. I'd have to go to an 8:1 system to allow for under load adjustment. But I was going to change it anyway as the present system really allows no adjustment (other than loosening.)

In fact throughout the boat there is very little sail control... except for sheets. Both the vang and the traveler, like the outhaul are very simple systems that cannot be adjusted under load. I plan on upgrading all of these. (silly me... spending all that time on racing boats... see what it does, makes one want to actually trim the sails)
