I reciently lost the starboard stays chain plate while taking my "cruising" Hunter 23 to the extremes in a regatta in Boqueron, Puerto Rico...(jejejejejeje..., it happens, u know..) From detailed check I discovered that the wooden plank that sits under the plate and the upper hull to which the chian plate attaches had some water damage. The plank broke and the whole piece, including the chain plate got loose, making the mast go down. Has anybody experienced the same problem...? I plan on replacing the plywood plank with solid teak and extending the metal bracket attachment or tang father. Any other ideas?
