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.

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.

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.

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.
