I am having an issue with my centerboard not dropping when I release the line. All of the blocks seemed to be operating correctly. So I pulled the cap and removed the centerboard (with major difficulty)

It appears that the board is rubbing against the opening where the fattest part of the board fits into the centerboard slot. I think I want to sand down the centerboard in this area but I have no idea what its composition is and how much can be sanded safely (if at all).

The other option is to sand inside the slot but that seems to present more issues with getting any sort of tool up there. Hand sanding that part would be an option.

Any help would be appreciated.
