BlankBob & Ed,

You might check if your centerboard pivot pin is worn or has a lot of =
play.

Another technique that may reduce the noise is to pull the centerboard =
up tight into the well.  If there is slop in the centerboard pennant, =
that can allow the centerboard to slap around.

If the depth of your slip will permit it, then lower the centerboard all =
the way down.  Not only will the centerboard not slap, but the boat's =
roll frequency will be reduced.  (i.e. the boat will not roll from side =
to side as fast)

    Had a great week sailing in northeastern Pennsylvania but ran into =
something that has me concerned.  While in the cabin in our slip =
everytime a wave from a passing boat hit the side of our boat I heard a =
thumping noise, proportional to the size of the wave.  I'm convinced it =
is the centerboard/keel as I cannot find anything else that appears to =
be causing it.  Does the centerboard/keel have side to side movement =
that can cause this noise?
