Lauri,,, I agree and disagree ... both.
Yes, a wind vane that will work in all conditions must be of high quality, and probably expensive.. No, a wind vane that will work ok, but not great, and won't be used in all conditions, just something to take the edge off. That is why I got looking at the sheet to tiller self steering system. Not for going around the world, just a system to take the edge off along the coast of New England. The question in my mind is: what did the lone sailors do before the wind vane? How did Joshua Slocum steer the Spray? Did they tie off the helm? And if yes, how long would the boat stay on course? As far as the "Vane" part of the system goes, even a dope like me can make that. It is the stainless and pendulem etc that gets the trouble going. Couldn't a vane be set up that would work with the tiller, but not a permanent system? I'm looking for the one hour wind vane. One hour to go below, take a s...t, eat, grab some charts, change the music, get a wine for the boss, ............. then back top, sit behind the helm ,,..... and wait for boss to drink said wine,,,,, then boss will get hot and come sit next to helmsman,,,,,, and then .............................. ??????????????????? another hour of self steering is called for. ============================== "Lauri Tarkkonen" wrote in message ...

How did Joshua Slocum steer the Spray? Slocum had no self steering. He'd balance the boat out and she'd self steer ok once so balanced. Beats me why you are making yourself crazy here. Many have told you that we tried and it didn't work. Lauri did try and it worked so that means it doesn't work for all boats and I'll tell you it won't work nearly as well as a tiller master or vane. How many replies saying we tried and it didn't work will it take? |

No, a wind vane that will work ok, but not great, and won't be used in all conditions, just something to take the edge off. Then you use it mainly in nice and easy conditions. That is why I got looking at the sheet to tiller self steering system. Not for going around the world, just a system to take the edge off along the coast of New England. The question in my mind is: what did the lone sailors do before the wind vane? How did Joshua Slocum steer the Spray? Did they tie off the helm? And if yes, how long would the boat stay on course? If you reaad Joshua Slocums book about his circumnavigation he just tied the tiller down. He said Spray would keep it's course for days. As far as the "Vane" part of the system goes, even a dope like me can make that. It is the stainless and pendulem etc that gets the trouble going. I believe that if you look around you will find some stores that sell various components for shelfs and storage systems and tarpaulin supports, that have tubes and different kind of angled and straight joining elements, so you can build anything you want. Couldn't a vane be set up that would work with the tiller, but not a permanent system? There are some laws in physics about the energy, there are systems that use the power created by the wane to steer the boat, but the wane is then a small sail. Look more carefully to the system Sir Francis Chichester used on his journeys. I'm looking for the one hour wind vane. One hour to go below, take a s...t, eat, grab some charts, change the music, get a wine for the boss, ............ then back top, sit behind the helm ,,..... and wait for boss to drink said wine,,,,, then boss will get hot and come sit next to helmsman,,,,,, and then .............................. ??????????????????? another hour of self steering is called for. It is hard to make any realistic proposals without knowing more about your boat. On the wind it should be easy just by using a shockcord or a piece of rope, on a reach or a run it is more complicated. The electronic tiller pilots are just done for this purpose and even the small ones will do on nice conditions and then they do not draw too much energy to ruin your batteries. - Lauri Tarkkonen ============================== "Lauri Tarkkonen" wrote in message ...

You can do that if you are going around the world, much harder Portland, ME to Portsmouth, NH. They would typically use a double head sail rig: Two jibs wung-out on opposite sides, each with its own pole. The jib sheet on each side would be led aft to a turning block, and then tied to the tiller. As the boat would begin to head up too much in one direction or the other, jib sheet tension would increase on one side and decrease on the other, thus pulling the tiller in the correct direction to head down wind again. Did they tie off the helm? And if yes, how long would the boat stay on course? Yes. They could go downwind for days and weeks at a time with little or no adjustment. |

The technique that Slocum used downwind was to sheet the main out as one
normally would, but the jib, w/ a club foot I believe, was sheeted in tight. When the main caused Spray to head up, the jib would force her head back down. Helm was probably lashed. I suspect that sheet to tiller requires so much trial and effort that one turns to other means. But as in many things, if there are no other options, one would be more determined to make the solution at hand work. "NE Sailboat" wrote in message news:ebS%g.7278$ke4.1160@trndny02...

This something I try to say, if you want a windvane, get a proper one, if you want something to carry your boat while you are in the loo, a tiller pilot is doing a decent job, and it doing it reasonably cheap, I have a good windvane, but while motoring and if I want just a temporary relief from the helm, I use the tillerpilot. If I know I am going to sail for the next few hour or more, I rig the windvane. - Lauri Tarkkonen |

Lauri Tarkkonen wrote: Do the low friction bearings come cheap? I thougt that here the price is related the other way around, the more friction the cheaper. :-). Well, sure. All the way down to a rock, which is max friction but free ![]() The first couple of cheapo rigs I tried had too much friction. Then I just used a bicycle hub... lasted only a couple weeks in the salt water, but if you buy a cheap 2nd-hand bike (or steal one) it comes with a spare. The geometry is worked out and with the tiller you have a continuous adjustment, because you can attach the line pulling the tiller in different postiions of the tiller, giving you control of the lever arm. Right, but unless your tiller in infinitely long, the system has to generate enough force to move it against weather helm (up to a point). There is a clever windvane rig I saw some time ago that used a tiller pilot for an actuator, and would follow the wind or the compass depending on which you chose. I have a good windvane, but while motoring and if I want just a temporary relief from the helm, I use the tillerpilot. If I know I am going to sail for the next few hour or more, I rig the windvane. One of the issues with using a windvane on some boats is that they generate apparent wind, and can wander all over the place as the accelerate & decelerate. I heard a story about a fellow who fitted one to a reasonably fast cruising cat, and with every gust the boat would accelerate & bear away, until suddenly it stalled and would almost come to a stop, and refuse to resume course. Tiller pilots don't do that, although they do have some other annoying shortcomings ![]() DSK |
