Wayne,, work or not ,,, I still can't figure out the attachment system.
On the lee side of the boat, away from the wind, the sheet gets pulled tight, usually wrapped around a winch and then pulled tight and cleated. On the wind side of the boat the sheet ( I am talking jib here ) is left loose.. until the boat is tacked and then that side gets pulled in.. Now, if the tiller is attached to an elastic line, to a cleat ... ( like my bungy cord system ) ,, the tiller needs to be controled from pulling into the wind.. Or, on a starboard tack ,,,, the tiller needs to be controled from moving to the direction of port .. that way the boat doesn't turn into the wind.. Ok ok ok ... so how does the sheet on the loose side come into play, ,, or does it? This is what has me confused.... only one side has a tight sheet or a sheet under pressure. Is the pressure side controling the non pressure side? ================ Even though this might not work... I must admit some interest after my bungy cord system. ================== I would love to get a wind vane system ............ but at $3,000 ??? Probably won't happen. I wonder if there is a Poor Man's Wind Vane... a system that could use the apparent wind to steer and the controls would go to the tiller in the cockpit. ========= "Wayne.B" wrote in message ...

I wonder if there is a Poor Man's Wind Vane... a system that could use the apparent wind to steer and the controls would go to the tiller in the cockpit. The problem is that if you want a windvane that works in almost any conditions and lasts for years and years and does not let you down when you have gone in the cabib to make some coffee and sandwiches or to goo to the loo, then it is not a cheap system to build. If you think that the power generated by the wind will be the one used to actually steer the boat, then you need some wind or your wane must be very big. In the best windvanes the steering action is geretade by the boats speed through the water with a servo pendulum oar and the wind is just controlling the angle of this oar to the water. They say, that a poor man can not afford to buy cheap,he must buy quality. I would not recommend anyone to depend on a cheapo windvane, this does not mean, that one should not be avare of ways to make tackles for temporary use, as it is possible you need it for various reasons while underway. - Lauri Tarkkonen |

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 ...

The geometry of these must be very cleverly worked out in coordination with the boat's steering characteristics. 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.

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 |

![]() Did I say I could not afford $3k, or did I say that it would not be a good investment for me as I am not planning a long ocean voyage. If I am going to spend $3k, I want to spend it wisely. Where I moored last summer there were numerous boats with wind vane systems, wind vane systems that never ever got used. Dah ??? So, I posted for info about a less expensive and less reliable system; the sheet to tiller system. Now I am Mr Cheapo.

So far I know how to read, you were the one taking the word "cheap" into the discussion. If we do not know about systems that work and are reliable in various conditions and advice againts cheap solutions, I do not see any reason to be offended. There are always people who believe that they can by good and cheap, but in most cases if you want to have GOOD and CHEAP, you end up needing two things. It is your prerogative to make whatever you please with your boat and money, but if you do not like the advice or comments on this list, remember they are at least cheap. Sometimes I wonder ,, I really do. So I wonder sometimes why people bother to give any advise here. - Lauri Tarkkonen =================================== "DSK" wrote in message ...
