If you're talking about shape controls, then they only affect the shape in a negative way. But they certainly control the main, they keep the reefed section bundled up & control it from blowing all over the place. Well, the only time I use the cringles is when I have my second reef in. For the first reef, they aren't used and the sail is unaffected. Downhaul.. as in using cunningham? Same thing for shape, but different controls. The hand brake or parking brake is different from the regular brake on your car, right? The cunningham is esentially a rule cheater. It provides a way to increase luff tension without pulling the sail outside the black bands. I guess if we're talking about racing... You're right, technically, that the backstay adjustments affect the mast directly, but the effect is to change the shape of the main (and jib I suppose). How about boom brake or jibe-preventer? :-) I'd consider that a "control line" but don't like them and have never used them on a boat I was skippering. If you can't avoid gybing, or keep control of the boom when gybing, then you need practice on the helm & sheet! OTOH for a long cruise with a windvane or autopilot, they are useful but in the way. They work great for any reasonable length of time... I wouldn't bother for just a few minutes, but the preventer is easy to rig and unrig, and is worth it in shifting wind.

Or a sail that is cut so it has no room to increase luff tension- for example, if the head is at full hoist and the gooseneck is fixed. Luff tension is luff tension. If you can't get it by pulling the top tighter, then you have to pull the bottom... and if the bottom is fixed, then you need a cunningham. BTW a lot of new sails are made with the tack free to float up & down as tension is adjusted.... not fixed to the gooseneck. BTW 2 if you have a sail that need the cunningham pulled on in light air, then that sail is blown (or the luff boltrope has shrunk).

So is PAYING ATTENTION I've known of two incidents where boats got in big trouble with a preventer rigged. One ended up gybing anyway, turning about 120 degrees and getting stuffed when the main went aback; the other narrowly missed getting run down by a large tow as the skipper tried to direct the crew how to unrig the preventer quickly so he could turn. Both cases were of course caused by inattention, not the preventer. But the preventer doesn't do anything a good helmsman can't do. The times I've sailed other people's boats with preventers rigged, it always seemed more in the way than helpful. DSK |

Flattening Reef That's kind of an old-fashioned thing, isn't it? There are a lot of boats out there with only one reef point in the main anyway Fresh Breezes- Doug King |

So is PAYING ATTENTION I agree that paying attention is the most important factor, but on downwind runs of an hour or so, a small mistake can translate into a big problem. The preventer is perfect for that. This is especially true when inexperienced people are at the helm, which is fairly routine if I'm teaching. I've known of two incidents where boats got in big trouble with a preventer rigged. One ended up gybing anyway, turning about 120 degrees and getting stuffed when the main went aback; the other narrowly missed getting run down by a large tow as the skipper tried to direct the crew how to unrig the preventer quickly so he could turn. Both cases were of course caused by inattention, not the preventer. But the preventer doesn't do anything a good helmsman can't do. I've seen this happen also... or similar anyway, but a preventer does do something even a good helmsman can't do... not require 100% focus for several days or hours. Even an excellent helmsman needs a pee break from time to time. The times I've sailed other people's boats with preventers rigged, it always seemed more in the way than helpful. DSK I would qualify that by saying "many times" instead of always. -- "j" ganz @@ www.sailnow.com |

Even an excellent helmsman needs a pee break from time to time. True. That's why it should *always* be school time when sailing. GIving other people practice and coaching; and getting coaching from others who have skills you want to develop, is one of the best parts of sailing IMHO. and it means that you should always have a relief helms- person.

Agreed. I could also say "in my limited experience" since my experience has been limited to the times when it was more in the way ;) DSK |

The traveler includes 3 adjustments: the main sheet and the port and stbd traveler control lines. All this presupposes a marconi rig. There are many other main sail types, which include other control lines, one of which I believe would be called a gullet. What does it do? Another would be a brace. Another would be a parrel, one of possibly 7 or 8, What does it do, to what sort of sail? Remember to think global and act local.

I don't want to be in a discussion with a Sockpuppet. I know Bart & Ganz to be real. I don't need any help with this subject, thank you. I just wanted tto point out that your answer wasn't serving the basic purpose of teaching those who don't know. As far as "real", everybody in usenet is essentially a sockpuppet regardless of what name they use. Ganz and Bart are no more "real" than anybody else here. Usenet is all ones and zeros. One becomes real, by demonstrating that fact by meeting someone in the group, or otherwise gaining credibility. |
