mast tuning

Post by Benjamin »

Just launched the typhoon we bought "dawntreader" hull #777 and discovered that the side stays had been reversed on one side. I bumbled about and switched them back but feel uncertain about what I've done. I've stuck a nail into the turnbuckles and tightened them but wonder what stresses I've put on the gear further up the mast. The turnbuckles themselves spin back unless I tighten the top and bottom bolts immediately. I've left the bottom pin fastened because the whole mast throws itself to the other side if I don't. Any advice? Should I sell the boat (which is utterly beautiful - my wife and two daughters and I just finished a day of sailing out of Vineyard Haven, Mass.)? She doesn't point but has a wonderful feel and responsiveness

I'm not sure what you mean by the stay is "reversed". There is probably a picture of what the rigging should look like in the manuals that are online on this web site. Typhoons are included in the manuals. If you can't find them let me know and I'll send you a picture from my manual.
When you tighten the turnbuckle you need to put a wrench on the post that is attached to the wire so that the stay doen't twist as you tighten it.
I wouldn't sell the boat over this as it is easily adjustable. Any questions j-u-s--t write back------------------------------------------------------------------------

Benjamin,

Just put my new Typhoon in the water last month. My first mistake was that the upper stay should be in the forward mounting hole, reverse of what I was used to on other boats. No bother to switch them on a calm day.

Most important is keeping the upper side of the turnbuckle (and therefore the stay wire itself) stationary while you tighten it, as Russ pointed out.

She's a great boat. Don't sell her!

Hold on to that Ty! With the rig tuned properly she should sail even better. As noted, when you turn the turnbuckles hold the flat part on the swaged end of the shroud still with an adjustable wrench.
Lie on your back on the foredeck and sight straight up the mast. First tighten the lowers until they just get a slight "twang"in them. The worry of all Typhooners is a too tight rig causing deck compression. But at least one experienced Ty sailor advocates shrouds "bar" tight. I tighten them until I can just start to get that musical note. Work slowly, about 1/2 turn at a time. Then adjust the uppers, again sighting up the mast to get it straight. A Loos tension gauge (about $45) will give you an exact reading, but when I measured mine I found I had gotten them equal just by feel. Tighten the backstay so that the forestay is tight. On a fractional rig like the Weekender, this will cause a bit of mast bend.
Then go sailing. The rig should now be just tight enough so that there is no slack in the leeward shrouds when sailing closehauled in a breeze.
The whole process is easier than it sounds. There's also a lot of good info on this board. Search under "tuning" Good Luck!

When you are done don't forget to put cotter pins through the bolts, and wrap the turnbuckes with rigging tape!
