Cooper smells like sewage once in a while. It’s from the weed. As far as the moorings if the wind is light bring the mooring pennant directly to one of the bow cleats and tie it off. Jump in the dinghy and run a dock line from the other bow cleat through the ring on top of the ball and back to that cleat. Match the length of the pennant. The ball is now trapped and can’t touch either hull plus you have a short tie off which can be helpful there with ball spacing. Very crude sketch!
