![]() "Walt" wrote BTW, dinghy sailors know how to tune rig tension ourselves. We don't need a $110/hr consultant to do it for us. How do you do it? Do you sail on one tack with about a 20knot wind and check the leeward shrouds and tighten the turnbuckles until there's no slack. And, then come about and sail on the other tack and do the other side? That's the best way to do it if you don't have some special too. That's what I was told at least. Oh the forestay you have to tighten so it stays pretty straight when sailing with your jib. That automatically tightens up the back stay. But when you have only three stays like my Tangerine it gets more complicated. Three's harder to get right than four. Cheers, Ellen |

Tighten all three up to a decent tension so that the mast is upright and there is no slackness that can lead to fatigue failure when not in use. Then, when you hoist your jib, tension up the jib really hard so that the forestay does go a bit slack and the luff wire of the jib has all the tension. The remaining two shrouds will then be correctly tensioned. |

The remaining two shrouds will then be correctly tensioned. It's harder for me because the wire in my jib rusted and the eye splice and thimble broke right off. I'm having to unstitch all along the luff to get the rest of the rusty broken wire cable out of there. So I can't hoist up the jib really hard or it might rip. So I have to do it with the shrouds and stay all by themselves... Cheers, Ellen |

(yes, the progeny of the sails makes a difference.) For my boat, I keep the forestay very loose with several inches of sag. Then I raise the jib on shore and tension the rig to 150 lbs as measured by a Loos gauge - at this point the forestay is completely slack. This gives me a nominal setting which I mark, and I'll go up or down from there as needed. The jib halyard is tweaked constantly while sailing (every 30 to 60 seconds) as conditions dictate - more tension for pointing, less for speed, and quite slack when sailing off the wind. Other boats are different. Don't try this with a keelboat. //Walt |

Hey, Walt! .You are a dinghy sailer and you have the time to tweak your jib _halyard_ every 30-60 seconds??? When do you get time to tweak your main and jibsheet, not to mention the rudder and also looking for the next windshift and/or gusts while also keeping your eye on your opponents?. Plus sitting her out to keep level etc.? My racing has been in lively heavily canvassed 12-14' dinghies and once the jib is up and the halyard tensioned that is how it remained while other things occupied my whole time. |

It's led back into the cockpit on both sides with a 12-1 purchase so I don't have to move to reach it. Likewise the vang which is also tweaked fairly often. Between the two, it's how you "switch gears" to keep the rig powered up optimally. When do you get time to tweak your main and jibsheet, not to mention the rudder and also looking for the next windshift and/or gusts while also keeping your eye on your opponents?. Plus sitting her out to keep level etc.? It's a balancing act. What's most important? Well, all the things you mention are more important than tuning the rig, and anyone who's fiddling with strings while ignoring these items is not going to do well. But it doesn't take much time or effort to reach down and tweak the rig - well, once you have the centrols installed to make it easy to do from the cockpit, that is. My racing has been in lively heavily canvassed 12-14' dinghies and once the jib is up and the halyard tensioned that is how it remained while other things occupied my whole time. I used to sail that way. But once I started tuning on the fly I started doing much better. The halyard tension greatly affects sail shape. Take a look at this picture (not me) http://www.albacore.org/USA/images/3_MegaWoofPlanes.jpg and observe the curve in the jib luff - this 'sag' affects the overall shape of the sail, and the amount of sag is a function of rig tension and wind speed. Since I mostly sail on inland lakes where the wind is *always* changing I have to adjust the halyard a lot to keep the jib shape where I want it. A different boat, more steady wind, and maybe it's not so important... //Walt |

You pull on the little white strings that run through the pulleys until something goes "boing." What a phony crock of dog feces you are, Neal. And a closet queen. Max |
