centerboard bolt leak

Are there any recommendations to prevent leaking into the bilge through the centerboard bolt holes? I have rubber gaskets and silicone sealant on each side of the centerboard trunk, with the fender washers to provide "squeeze" pressure, but on windy days the leaking is significant. Should I use neoprene washers/gaskets?

Discusses a possible alternate source of a leak.

Unfortunately I couldn't open any of the external links, but the "nipple" fix is standard DSII lore and you should find plenty of discussions here in the older posts.

I've only ever sailed on someone else's DSII but the amount of water that got pumped along the uphaul was prodigious. Any leaks in the connection between CB trunk and the opening into the cuddy will definitely be noticeable.

Good luck and have fun spelunking in the old posts.

Also, check your bilge drain plug. Mine looked well seated but I kept getting water sloshing around, turns out it was cross-threaded and leaking.

Thanks for the tip on the old posts. I need to check the boat but I maybe be on to something.
One more question: Do you know of any place that makes canvass covers for the day sailor? Mine is falling apart. I have used heavy plastic tarps but they don't last more than a a couple of years and it seems like a waste to keep replacing them.
