[bolger] Re: mizzen vs vane
Thank you very much for the information. I am perhaps the victim of
armchairitis with regard to wind vanes, but it's tough to try one out up
here in the mountains (it is hard to even find places to sail). I'll have to
look through the books and see what Bolger has drawn in the 30-35' range
with a transom-hung rudder, then figure out if I'll be able to afford it
after my kids have gone to college (Yikes!),

I gather from your letter that you are treating your design information as propriatory, and this I quite understand. I am still curious as to what you produced for $111.00 that could steer a five ton, thirty-seven foot boat. Was it an auxiliary rudder vane, a horizontal axis vane, a rudder tab, or a servo pendulum? I suspect that a servo system would be a challange to engineer, as would a simple rudder tab for LS2's inboard rudder. I get the impression from my reading of Letcher, Street, Hiscock, and many others that much of vane design is a trial and error process. How long does it take for you to get a vane to work on a particular boat? How much does it cost the boat owner for both materials and labor to have such a job done? Finally, have you investigated the efficacy and long-term reliability of such "home-brewed" vanes versus commercially available rigs such as the Scanmar and Fleming offerings? I know I'm asking a lot of questions, but I hope to run away to sea when I grow up (I'm only forty-eight years old now) and I don't particularly enjoy steering as a full-time pursuit,
Thanks!

certain way as steering by sail set is effective on only a few points
of sail in a typical vessel and a vane - in theory at least - is far
more capable.
I think Marin-Marie details one non-vane system in a book called "Wind
Aloft, Wind Alow".
Hasler's vane and others are covered in an AYRS publication on
self-steering which I think is still available.
Tryhttp://www.ayrs.org
Disclaimer: don't use a vane, don't plan to, just happen to know where
some info on 'em is.
How did you design this vane? What kind of materials did you use? Have you any plans or pictures?
Thanks!

As far as I am concerned a windvane self steering gear is just about the best investment you can make to improve the quality of life on a boat. They do not have to be expensive as the vane gear we crossed the Atlantic with cost us a grand $111. to build and a couple of afternoons labor. They are simple to use..consume no power and allow you to go below and take care of buisness when needed. During our 23 day crossing I doubt we steered by hand for more than six hours.

As I personally have exactly zero experience with windvanes, I will refer you to John S. Letcher, who has had quite a bit. In his _Self-Steering for Sailing Craft_ (International Marine Publishing Company, 1974), when he is not actually explaining how to build and use a windvane, he spends a lot of time raging (calmly) about how complicated and unpredictably ineffective they are. His basic thesis is that for a boat to use a windvane effectively, it must be balanced, and that a boat thus balanced can be easily self steered without a vane, so why bother? Of course, the book was written before most of the manufactured vanes were available, but the sea and the wind haven't changed. If you can get a boat to steer herself with her mizzen, or a length of surgical tubing, why spend big $$$ on a vane? The book has been out of print for several years, but you can probably find one used through Amazon (yuck) or a used book dealer,

On my AS-19 I have gotten used to the mizzen as a way to
steer the boat. Then I read Annie Hill's book and
they seem to be sold on the weather vane self-steering.
Does one method stand out over the other for self-steering?
Is it sensible to have both - maybe the using the mizzen
going into the wind and the vane when going ahead of the wind?
