I tighten mine quite tight (Mk1 wooden boat), the idea being that the centreboard rotates around the bolt and that the bolt does not rotate with the board. There are various rubber seals that are used, including Grolsch bottle seals. I have made my own seal with a 10mm rubber O ring and a 4mm rubber gasket fitted under a 30mm dia stainless washer & nyloc nut. It cured my annoying leak in that location.
