I had the same concern but settled on the idea CLC knows what it’s doing. Turns out the extra space is a good thing. When underway lateral pressure wedges the board in place and the extra space allows easy retraction when it gets fouled with rocks and mud. There is a little thunk on tacking that is kind of comforting. Same is true with the mast and mast partner, lateral loads lock it in.

   Not to worry.  You need that addtional space.  The pressure put on the dadder board while sailing will take care of any slack.  When on a beat, you'll have a hard time pulling it up I suspect.

OK -- I'll leave the fit alone.

THanks,
