RVG Windvanes

The RVG is quite a workhorse. My first one disintegrated due to dissimilar metals and I found a newer one to replace it with. Our boat had lots of weather helm, so it was important to offset that with the ship''s rudder, but unless the wind changed and therefore the weather helm, it was great. One six day trip from Panama in 30 kts hard on the wind sold me. I don''t think I ever really adjusted it. It is very powerful. Even downwind it was great. However, I did modify it a little. The key to a good windvane is getting out as much friction as possible. I replaced one of the worn out bronze bushings with one of nylon. Had it made at a machine shop in Mexico.

Their weakness is corrosion. Nothing can be done except to try to isolate metals with teflon pads or tubes. Since it''s only 4 screws to take it off, it''s best to remove it if you won''t be using it for awhile. The second one I bought was in better shape and I scrounged a few parts off of the old and rebuilt it. It worked even better because it had a larger rudder (many were custom fitted). There is no source for parts - I''ve looked everywhere. When you see a used one, grab it. I paid $150 for the first one in Mexico and had to rebuild it (mostly bushings made at a machine shop). The second one was $300 and in very good shape.

Good luck.
