Excessive weather helm?
I must not be understanding what you are doing. As I see it, if the main is centered and fully deployed while the jib is luffing I would expect severe weather helm. Clearly in such a case the center of force is well aft of the CR.
I''ve been told to think of a boat as you would a dart. As long as the feathers of the dart are well aft of its COG (CR) the pointed end will be first to arrive at the intended target. The main (on a sloop) is very much like the feathers on a dart. Fortunately, sloops also have a headsail which when deployed help to move the ''feathers'' forward and hopefully closer to the CR. In fact, if the headsail were to be the only sail deployed, the CF could actually be forward of the CR and the boat would instead have lee-helm.
At least, that''s how I have been taught to understand it. If I''m correct, then you need to reduce the main by either moving the traveler leeward or reefing it, and setting the jib to be more effective. Both of these procedures should have the effect of reducing weather helm. BTW, as you probably know, some weather helm is desireable.
