This seems too simple, but if a fellow had an old jib off a smaller boat (110 or smaller), why not hank it onto the backstay, attach the head to the topping lift, the tack to the outhaul, and somehow crank the clew down towards the gooseneck? Mainsheet would be used to snug up the boom as well.

How large might be too large for a riding sail? Would the pocket cause problems? (as opposed to a flat sheet?).

Also, Arlyn offers that the harness on the anchor line helps reduce hunting as well - suppose this were combined with a pulley or other movable system to maintain equal tension on each segment of tha harness?

Simple

There are many theories about why a boat hunts on its anchor rode. Some say it is the stretching rode and as the boat is pushed aft, the rudder steers the boat askew, others think it is hull lift, others simple vector forces.... maybe its a combination of several things, remaining nebulous enough to keep a finger off it.

And... there are several approaches to dealing with it... maybe the best, is what works on a particular design.

And... there are different goals... some may wish to use a riding sail that puts and holds the boat over on one tack... while others may have the prime concern of dealing with the high straight line winds of a thunder head and not wish to induce a tack or add any more loading than possible.

Some may be sensitive to noise generated by a riding sail and others may be such sound sleepers that noise of a slapping riding sail is no issue.

I once spent the night in an anchorage with a smart wind blowing and the neighbor boat had an unchecked halyard... how could he be sleeping through that...impervious to its obnoxiousness?

I expect that many a storm trysail has doubled its use as a riding sail.
