I wrote several responses but they all sounded stupid. We do get some vibration in our rig from different engine/driveline speeds but not a clunking. We get a weird sound (Could be a clunking) if the dinghy is swinging in the davits. I have forgotten to pull the bumpers up resulting in a thumping sound on the hull. You are a ubermensch for diving in the sound to take a look. I watched a guy do that in an anchorage on San Juan Island as the sun went down once and I got cold just watching. His anxious girlfriend was very attractive and warmed him amply upon clearing a dock line from the prop. If you sailed a bit On the trip and didn’t feel the clunking, that might give you some direction, but not definitively. Based on what you have said, I pick driveline! Not rudder. Maybe a worn bearing. It is a mystery!
