Helo Thierry , I push around an 9 mt 9ton spray schooner junket rig mostly experimental. my idea was to get controll of the baggy part of the gaff rig .My main sail runs on amast track and has baton pockets sealed by tied tape witch dide,nt stop the batons overshooting the mast and jaming when raising the sail ,so my answer was to cut 6 inches of the batons nearest the mast, it cured the problem whether it is eficient or not I d,ont know. My boom and yard are on home made sliders in the track and I use two halyards ,on one winch to raise the sail , one on the yard and one on the peak . I yocky the sail up keeping the yard parallel ,reason to stop the yard catching the lazy jacks I get the odd tangle but what the hell its a boat . the sheet must be loose on the way up or it will effect the stress on the rig and slack must be taken in on the way down other wise you could end up with a mares nest . I don,t know how your yard is attached to your mast whether its u shaped or full circle either way you could do the batons the same , I use plastic pipe 50 mil by 3 mil its flexible and has,nt broke yet and I get some shape . My fore sail has open batons tied to the sail Its simpler and I like it . I have stays on both masts and let the sail rest on the stays, on the run the batons flex around ,all you may get is chaf on a long run . Your jib will help you tack ,mine is not very good , no jib .
