10677Re: [SabreSailboat] rigging problem, and shuddering rudder
- Jun 1, 2007Don't think the bow is in the mast, because, then the side towards the bow would be loose, not the other side. I did remove the bottom plate. There was just one screw, which of course sheered off, and I had to drill another hole. I did that on the other side, and the mast was sort of a sloppy fit. Could that amount of misadjustment cause the problem? Also, if a bow in the mast is the problem, then could it be because they left yhe mast supported all winter just from the two ends?I'm actually more concerned now with the steering vibration.Dave Lochner <davelochner@...> wrote:Sid,Once a mast gets any kind of bow in it, its hopeless to try and get it out.Do as Pete suggests, loosen everything, shake it a bit, and let the mast recover and get sort of straight.Then slowly start over again, beginning with the uppers. Tighten the turnbuckles to a loose hand tight and make sure you're still in column. Then tighten one side one turn, then the other side one turn. Work slowly and check both the tension and the straightness of the mast after every adjustment.DaveOn Jun 1, 2007, at 12:37 AM, sid wax wrote:The other 4 stays all had plenty of room for adjustment, But the 2 I mentioned were really far out of whack. As I recall, I didn't try adjusting the uppers, but any adjustment on the other lowers seem like they would either increase the bow or further slacken the port lower.One thing I did notice, though. I am not sure whether the PO had a turnbuckle boot on the backstay, but with a boot installed, it interfered with the traveler, which indicates that somehow the rig should be further aft. I tightened the backstay, but that would even further stretch the forward starboard lower, and that one is so slackened that it is is almost coming apart, and is still tight.I guess I depended on the riggers to have a clue how to set up the rig. I'll have to start from scratch, loosen the lowers and get the uppers straightened out first.&! nbsp; The procedure ought to include using the halyards to check the rig for plumb, and then trying to adjust the aft lowers, then the forward lowers. I'll need more advice on fine tuning, but the rig is so far off now, that I am concerned there may be some more serious problem.The steering is another issue, and everything I have read says that you really have to tighten the cable, but I wonder if it could be too tight, and binding someplace, and/or maybe it just needs proper lubrication. The yard guy said he had opened it up to examine the system, but presumably he just gave it a quick look, and I will have to open it up myself and go through the full Edson maintenance procedure. But boat goes in this week, anyway.

what about slackening the port upper and tightening the starboard upper?
What about the starboard aft lower and port forward lower? Can they be
respectively loosened and tightened?
