When my 23.5 is in the slip I can hear the centerboard slightly banging in response to wave action. Is this normal or do I need to take a look at the pivot point?

Hopefully Uncle Crazy Dave will see your question and respond. I raise the centerboard of my H260 while in the slip just to avoid potential banging.

It is called "keel slap" but it should not pose a problem as the board is not ballasted. The board is there to counter drift when under sail and can be raised when sailing dead down wind or when at anchored or docked. That is a water ballasted boat, right?

I raise mine while in the slip.it eliminates the problem your having and stops the wear on the keel bolt bushing.

The centerboard rotates on a metal pin which leads me to believe that it has or the hole of the centerboard is not to specs and enlargened. to see how bad I would suggest relmoving the centerboard.

The amount of "slap" will be commensurate with the wear on the hinge bolt/ hole combination. It can range from a small "tic" to a large "TOC". You can probably ascertain its condition by diving on the centerboard and manually rocking to see how much play there is.

Benny;

I know the boat very well as I was very much involved with the boat from the first that left the factory behind my car to the very last one and quite a few in the middle.

Thanks guys. It does this in the slip with the board up so I guess I'll have to check the board pivot when I pull the boat this fall.

Hi Cedarsail,

I have one of the original 23.5's, hull #18. Mine always had a little "bump, bump, bump" with the board pulled up tight, depending on the motion of the waves. I figured it was just the buoyancy of the centerboard combined with a little play in the line and wave motion.

Twenty-two years later it has never caused a problem :)
