"Ian Malcolm" wrote Knowing and accepting that I am probably talking to one of ADN's many socks, but on the off chance you are for real or ADN is pretending to be the fount of all nautical wisdom and is relating our replies to some cute young new boatowner, pretending they are his own words, I'll have a shot at being helpfull. At least its vicarious sailing :-) Thanks for being helpful. It's what I hoped for when I subscribed here. Instead I got people bitching me out for being somebody else.... The same person who took all your other photos could take this one . . . I can do them faster myself. Besides I only need somebody to take pictures of me. I really would like to see an over-all shot of the bottom 1/3 or so (where the wire broke) as well as the closeups. Why not spread it out accross the cockpit and sit on the coacroof to take a picture of as much of it as you can fit in the frame? As you saw I put it up instead. Easier to see how it looks that way. On a dead calm day, wet the sail to give it some weight and tension the luff between two stakes or posts a few feet off the ground then tension the clew keeping the sail level until the shape of the sail hanging down looks about right. Crouch down and look at the shape. The maximum depth of the curve should be rather nearer to the luff than the leach. If its past half way back, replace the sail. If there is *any* doubt, tape accross the sail with black electrical tape parallell to the foot at 20%, 40%, 60% and 80% of the height KEEPING THE TAPE ABSOLUTLY SLACK and as streight as you can when you apply it then stretch the sail as above and take us all a photo showing the *whole* sail from the foot looking towards the head, down at a shallow angle. It also helps ifyou can get someone to hold a thin streight rod just barely touching the luff and leach at the 40% height so we have a reference line. Man, that all sounds too complicated. Even if I did all that and found out the sail is all stretched out I'd still probably want to keep using it. Elle Niño only has two feet of draft and doesn't go to weather very good because it doesn't get much grip on the water so bagged out sails probably don't make that much difference. But you sure sound like you know a lot about sails and their shape. Good first step, but have you priced replacements? They may come good if soaked for an hour or two in a 25% solution of a Formic acid ciontaining kettle descaler, working their pistons at intervals and when they have freed up, rinseing *very* thouroughly, drying and spraying with a good brand of silicone lubricant. Yes, I'm gonna take all the corroded brass parts out and throw them away. Like I told Tom I'm gonna use plastic swivel hanks instead and it'll solve two problems at once. http://www.sailmakerssupply.com/prod_detail_list/24 If they are sewn on, put them aside to fit later otherwise if held by a bronze 'claw' you may need to anneal the claw with a blow torch while protecting the body of the hank with a sopping wet rag to avoid loosing the temper in the spring. Any which show signs of cracking in the claw, dont work freely or seem to have lost their spring must be replaced. Those claws are corroded and brittle. Two claws broke when I tried to pry them off with a screwdriver That's why I got a couple new ones. But the new ones were so stiff I had to hit them with a hammer to close them up. I couldn't even squeeze them together with pliars. Getting a sail shop to do *anything* wont be cheap and they have a much better press for putting eyelets in than you or I can hope to have. Take the hanks off then ask the shop if the sail is worth saving and if so, roughly how much to do the whole job except refitting the hanks? N.B. a general Canvas shop will NOT have the expertize you need unless they have a sailmaker on the staff. That's why I decided to do it myself. Like I said to Tom, I'm gonna get some sail tape and use a friend's sewing machine and sew it on myself. I can even put in a little bolt rope to fit the hole in the swivel hanks. Unless the holes are badly chewed, you can probably re-use them if you go to a slightly larger size. You use the punch in the eyelet kit to cut the holes. A small patch hand sewn over the luff wire and accross both sides of the hole can be used to fix any bad ones. Tapeing the whole luff unless done by a pro, is likely to upset the luff tensioning and give an unsatisfactory result. Maybe if I'm careful with sewing it and make sure the tape is tight it'll work. Besides when pulling the halyard real hard it'll stretch the cloth out. That's one reason why I don't want wire in the luff. It doesn't stretch... Ideally you'd hand stitch the rings for all the new eyelets before closing the 'hat' over the new leathering using the punch and die in the kit. Won't need to do any of that with the plastic screw on swivel hanks.... To get a streight luff. When hoisted on a small boat, all the load should be on the luff wire with the forestay just slack. All the hanks do is controll it while hoisting or lowering. Consult a decent book on traditional knotcraft or sailmaking for the correct way to tye the hanks in. Won't it all be on the luff anyway? It'll have tape and a little bolt rope to take the pull away from the stay. NO WAY. Only applicable to a sail with a high tensile fabric tape the whole length of the luff. Is luff tape high tensile fabric? What you actually need is a loosely fitted luff wire extending right to the eye at one end and actually forming part of that eye and with a talurit eye in the other end about an inch beyond the corner of the sail. The eye at the free end of the sail is laced to the corner to set the cloth tension for best sail shape after the sail has been hoisted as tight as possible. Thereafter check the laceing occasionaly. Its handiest to have the head fixed to the wire and the tack free. That's how it used to be but it's too hard for me to do that myself..... DONT cut the sail. Oxalic acid will dissolve the rust. Its usually sold as a powder wood bleach. I reccomend a strong solution in hot water, applied and left to dry in the sun a few times then the next day more solution and gently working at the edge will probably free up whats left of the wire. Once you have removed it, patch any holes and work a piece of solid wire in to let you pull through a nice new piece of 3mm 7x19, which it's worth treating with melted beeswax before you use it. Then you just need to get the talurits on the end swaged, and do the other items discussed above and you're golden. I won't cut the sail. I'll snip the stitches in a few places and get the wire out the back way. I can resew the sail by hand using the original holes and it'll be easy to push the needle through. There are companies that re-proof sails commercially. I am not sure if its worth doing though. Dodgy seams can be oversewn by hand if the sail cloth is still sound enough to hold stitches, if not, its new sail time. There is a product callled seamcoat or something like that for treating properly stiched seams to protect and strengthen otherwise sound seams. DONT use ArmourAll. It wont do any good and will make futture repair work impossible. OK I won't use ArmourAll. It would probably make me slip right off the deck anyway. Maybe I can spray it with starch. How about a nice picture of you sailing just for me? It would cheer me up in our horrible winter weather no end. I'd like to see you on the helm with the boat sailing with a bone in her teeth. I'll see what I can do since you've been so nice to me. Maybe I could get somebody in another boat to take a picture like that.... A bone in her teeth means fast, doesn't it? Thanks, you've been very helpful. Cheers, Ellen |

They are Ok when the sail is up and tensioned but before you hoist and whenever you lower it you will find that the sail will fall into folds and this will allow the hanks to turn and slip off the wire so you will have to crawl out on the foredeck all the time to replace them and by the time you get back to the halliard some will have come off again... I hav a 14' sailing dinghy with them on and am going to replace them when I get time. They are cheap and nasty. Use bronze snap hanks. I do not like the ones that involve bending a tang. I use the ones with two holes that allow you to seize them on. |

One little screw hole's not gonna hurt the sail. I can always put brass grommets and brass hanks on later if the plastic ones don't work. But it looks like they have to be twisted 90 degrees to get them off. And only 90 degrees one way. I think maybe yours are upside down or something. Cheers, Ellen |
