Hey simple!
Correct. Traveller is wrong for current course.
LOL.......... How would you know? Traveler was above the centerline. Boom was in the middle of the boat. S/V Express 30 "Ringmaster" Trains are a winter sport |

Good lord. There's not one pleasing line on that sailing brick!
It does have a pretty ass end. Tee hee. S/V Express 30 "Ringmaster" Trains are a winter sport |

Kinda hard to tell that from where your sitting. I was trimming the main and the top batten was parallel to the boom. It was really light air. Loco, I was offering critique of Navvie's 'perfectly' set & shaped main. For some reason AOL will not let me look at your pictures. For the leach, I like to look at the leach ribbons and the overall twist. Sometimes it is hard to tell. In Navvie's pic you can't see the leach ribbons (are they blue, for some reason? Are they missing?) but it looks like there is no twist at all. Fresh Breezes- Doug King |

Leach closed. No it isn't. You cant tell the twist from that camer angle Why do you have a backstay antennae and no wire to it? Is the wire lead up the mast and to the antennae at the top? Well spotted. The wire is off. Cheers MC |

Don't be silly, look at the the tell tales.

Hey simple!
Look more carefully. There are ribbons at each battenb and they are all
flying at that moment. You simply can't see twist from that camera angle so the twist must be sufficient to keep the top ribbons flying...

Not enough draft in upper sections
The navigator© wrote: You must be used to really baggy sails. Actually, no. I'm used to lightweight dinghy where the max depth of the chord is only 12%. But in this case, the issue isn't bagginess at all. It is the simple fact that a well cut sail will be relatively deeper in the upper sections. In any event, in light air, a big round section with a relatively flat entry will keep attached flow and build up much more power than a draft forward conventional airfoil shape. Leach closed. No it isn't. You cant tell the twist from that camer angle I can see the topping lift, whih is presumably straight, and the distance from the battens to the topping lift does not appear to increase towards the middle of the sail. Also, it appears (could be due to camera angle) that all the battens are at the same angle. Looking closely, I can see what might be leach ribbons flowing. That's a good sign. Why do you have a backstay antennae and no wire to it? Is the wire lead up the mast and to the antennae at the top? Well spotted. The wire is off. OK, that's allowed Fresh Breezes- Doug King |

In any event, in light air, a big round section with a relatively flat entry will keep attached flow and build up much more power than a draft forward conventional airfoil shape. There we disagree, in ligh airs the angle of attack of the leading section must be close to zero to attach flow. Hence it should be full. Surely you would agree that aeronautiucs shows that deeper foils generate more lift at low speeds.... Leach closed. No it isn't. You cant tell the twist from that camer angle I can see the topping lift, whih is presumably straight, and the distance from the battens to the topping lift does not appear to increase towards the middle of the sail. You are forgetting the roach... Also, it appears (could be due to camera angle) that all the battens are at the same angle. Yes it's the camera angle. the top tell tale could not be flying at 33 deg app. if there was no twist. Looking closely, I can see what might be leach ribbons flowing. That's a good sign. Yes they are, and it is. Why do you have a backstay antennae and no wire to it? Is the wire lead up the mast and to the antennae at the top? Well spotted. The wire is off. OK, that's allowed It's a good idea until you go offshore. Means that the connections don't 'weather' until they are needed. Cheers MC |
