Doug, Is Navy Brass bronze? If a new CB were to be cut from stock using a CAD file, would the lead and trailing edges have to be shaped, or it the existing board just a flat section of metal? What about having the board cast in a different metal? Would that be prohibitively expensive?

Two searches will cover the topic, type the word "galvanize" in the first search term box, and "centerboard" in the second search term box. You'll get several hits. Then, go Back and use "CB" instead of "centerboard" for a second set of messages. There's quite a bit of discussion on this subject, but not sure any consensus was reached. Message six under the second search (galvanized and CB) by Howard Audsley discussed the possibility of getting a CAD file (probably a .dxf) made that could be used to get steel, or Navy Brass or SS if you're rich, boards cut more cheaply. If there's enough interest, maybe it's worth a bunch of people getting together to pay for a CAD file to be used by anyone who needs it. I'd go in on it, and it could be downloaded from the MSOG site. 2) The Potter people talk about having decent results galvanizing their CB, which are steel (Montgomerys are originally cast iron on the older boats, FG later on): "One of the things that has become popular (and standard equipment) on the Potters is a galvanized centerboard. When I had my P-15 I was planning to have the centerboard galvanize dipped when the paint gave out. My board was a slab of steel... Don't know if it can be done with cast iron. Anyway, for what it's worth, the Potter Yachters seem to have good luck with the galvanized boards." Maybe someone who subscribes could write to their listserver and see what works best re: painting galvanized, etc. Unless Bob Eeg, Jerry M., or Judy Blumhorst want to just tell us... ;) Doug At 06:45 PM 2/24/02 -0500, you wrote:
I'm sure this question has been addressed exhaustively in the mailing list archives, but I've never had much success accessing them.
Is it possible to galvanize the older M17's centerboard? If so, has anyone out there done so?
Would galvanization be preferable to epoxy painting? I imagine epoxy painting and filling would be cheaper and would make faering easier.
Would galvanization be prohibitively expensive?
Would galvanization give complete corrosion resistance?
Thanks!
