Richard I saw one out in the Pacific that was mounted on an outboard rudder. The wind vane was a simple V shape on top of the rod leading to the trim tab. The vane was mounted on a collar that could be adjusted for the wind. Actually I think he loosened the set screw and let it weather cock and the reached back and tightened it up. Very simple and he had used it from Samoa to Japan, on a home built 36'r. Leanne |

There are several systems and it was very common before they came up with the servo pendulum. If you have read Peter Förthmanns books, then you should have noticed him explaining such things on pages 46-47 and there are pictures of two on page 46. I think you should take Peter's book seriously, he knows what he is talking about. I studied this topic about 5 years before I decided on the system and now my vife says: Why did you not buy this earlier. - Lauri Tarkkonen |

Lauri,
What boat do you have and what sort of sailing do you do? Yes I have read the book. I am deciding between Aries, Monitor, Sailomat and Windpilot.

Lauri, What boat do you have and what sort of sailing do you do? Yes I have read the book. I am deciding between Aries, Monitor, Sailomat and Windpilot. I have a 40-foot sloop, I am cruising with my vife in the Baltic, visiting in the summer Sweden, Denmark, Germany, Poland, Lithuania, Latvia and Estonia. I made some studies in the same field and Windpilot won hands down. I have installed and sailed with Aries on a friends boat, it is heavy and clumsy, more trouble to install, and the dimensions of the components do not match the loadings applied on them. Monitor is a stainles steel copy of Aries. Sailomat is too complicated, they did not get it right. Read the book again, Förthman knows what he is talking about. The auxiliary rudder systems are a nuisance when you try to reverse and manouver in harbours, Aries and Monitor are vulnerable in close quarters, Windpilot is superior in all aspects to these. - Lauri Tarkkonen Regards, Dennis Gibbons S/V Dark Lady CN35-207 "Lauri Tarkkonen" wrote in message ...

You should take a look at the Cap Horn. Although primarily designed for the very neat, integrated installation, they are also available for outboard mounting with outboard rudders in which form the installation is no more difficult than the other models. Their mechanism is dead simple and very reliable. They were new on the scene when the book was written so they don't get much coverage aside from some comments that they don't have some adjustments that other vanes do. Not a big issue in my experience. I love mine. -- Roger Long The idea is neat, but the geometry of the 2:1 gear gives you better steering and better damping. This is a bit complicated to explain, but because it is in the books so I do not bother to do it here. To my taste it is too complicated. There was a professor in general mechanics and engineering who started every lecture by telling: Simple macines are reliable. This has been forgotten. I gave Cap Horn a very serious look and thought in the Düsseldorf boat fair, but it really did not have anyting to compensate for the complications of installation. - Lauri Tarkkonen |

Yes, the Cap Horn is complicated to install if you do it as intended but the result is a simpler boat, cleaner appearance, and simplicity in maintenance and operation. You can buy an outboard model and have the simple installation. The mechanism of the Cap Horn is elegantly simple. That's one of the things that attracted me to it as a designer of boats and nautical things. They have certainly proven themselves. The installation won't be as big a deal on all boats as it was on mine. My lazzarett was just a couple inches too big to reach the critical spots so I had to work inside. I also could have done it in a much easier fashion but I wanted to get the braces up and out of the way. I would rather have done that stuff for a few days in the winter and spring than have lived with a drum on my wheel and lines running all around the cockpit for the rest of my sailing days. It might be different for voyaging where you set up the self steering and then don't go to that part of the boat for days on end. The Cape Horn makes self steering practical in coastal waters. The ability to disconnect it in two seconds is great. Whether I am using it or not, there is no visible sign of it inside the cockpit coaming other than the wheel turning magically back and forth. Obviously you do not know Windpilot. You have the gear bolted on with four bolts, and you can remove for winter removing two bolts, and about the appearance in the cockpit, only two strings coming to the tiller. You can release the tiller in a second by just pulling the chain of the slot. If you do not use it, it is turned up and in my case it does not go over the transom when turned up. - Lauri Tarkkonen -- Roger Long |

Take a look at the Fleming servo unit. 316L investment cast parts, common bearings with popular winches, no control lines req'd, provides emergency rudder as std. Add a push-pull stick type auto pilot and your home free. Free that is, except in your wallet. Lew |
