- Zinc anodes are commonly used on both sail boats and power boats with a great degree
- of success. They come in several different sizes and shapes depending on the
- application. Knowing several people with steel hulled boats, I have seen that they
- tend to use more zincs that fiberglass boats, but I think that for a spar bouy
- you would not need a very big zinc for a four month test. I would recommend marine
- grade primer and antifouling paint (often a good bit of zinc in there too). You might
- want to check with a local boat yard for excess paint (It sounds like you do not need
- much), and advice on best performance for your area.

- Good luck!!
