Seems there is always someone having problems with one of the old cast iron centerboards. My boat has the same problems and I'll be working on it soon. It would sure be beneficial to a great many of us if a suitable replacement could be created. I was surprised to learn the newer M17's board is so much lighter. Is the weight difference made up in the keel? Could a lighter board be used on an older model? I realize the board on the newer boats won't fit the older models, but if a lighter weight model could be made to replace the cast iron, without too much loss of performance or stiffness, it sure would be a lot easier to handle. Also, earlier discussions speculated on the possibility of getting a professional to build some boards if there was enough interest. Count me in.
