I have the centerboard of my 1969 DS1 out and notice there are two holes (drilled holes, not holes due to accident) in it. One is about 3" from the leading edge and 12" above the tip. It goes only part way thru the board and appears to end in a hollow area inside the board. The other hole goes all the way thru and is located about 1" from trailing edge of board and 20 inches above tip. Both are about .25" diameter. Anyone know what these holes might be for and wheter they should be plugged off? I'm tempted to at least plug off the one that appears to go into a hollow area of the board.
