I searched for a discussion, but didn't find one on C-Brats. After many attempts, we discovered an easy solution to keep the mooring ball from banging against the hull in the middle of the night. We use a bungee cord.

Once you've secured the mooring ball. Attach a bungee from the anchor or anchor roller directly to the mooring ball ring. You want the bungee tight enough to prevent the ball from touching the hull, but with enough stretch so that the mooring line(s) will bear the load when the wind blows and stretches the bungee. You may need to adjust your mooring line a bit. It took us a few tries to get this right, but now we sleep well. :moon
