John, My M15 was the same as yours and I also could not get the boom to the center. I replaced the opposing blocks on the traveler with single block lashed it in place in the center so that it won't travel. I can't say that it makes a lot of difference but it makes me feel better :-) I still struggle with getting any twist to the sail in light air and have been tying a line to the boom vang attachment point and hauling sidways to the up wind jib cleat. It gets more sideways pull than down but still doesn't twist enough. I suppose if I was real serious I would put in a boom kicker and lift the boom so the sail twists but then I don't race unless you are in sight :-) I checked a couple of web sites on the split tail and is in and out of favor on Snipes and 505s. It seems as though the split mainsheet ends become the traveller on the M15. Each end of the split tail is fixed at the the side deck or transom corner. The splice has to be thin enough to go through the last boom block. As the boom gets close to the center the pull is starts to change the side to more downward. The web sites seem to indicate that the split is a weak point and will eventually break. I like my fixed block in the center of the traveler line. Enjoy. Doug Kelch M15 #310 "Seas the Day" "John R. Butler" <theoldcat@cox.net> wrote: The way my M15 #361 is rigged, the mainsheet is reeved from a becket on the block at the end of the boom, down to the upper block of a fiddle (?) block, back up to the boom-end turning block, thence forward to a turning block and down to the fairlead and cam cleat on the bridge deck. The lower block of the fiddle block carries the separate line from the outboard ends of the transom. (I hope this is clearer than mud…) This arrangement is rather unsatisfactory, since the boom can not be hauled in much more than over the quarter, and I find Rejoyce! points higher with the boom amidships. Gary O. has been kind enough to provide me further info on his split tail on his M17 LB/GF, and as I understand it, proper adjustment of the lengths of the two tails allows the splice to become "captive" at the block on the boom end, causing the boom to haul in amidships. If I have this right, have any M15s been rigged this way? Can someone provide me verbal or photo guidance?
