To clarify - I have only heard this noise when I have been down below in a boat. The noise appears to come from all parts of the hull below water. I can be (almost!!) certain that the noise appears even on a newly-antifouled boat, so feeding on algae could be contra-indicated by that. My boat is a cold-moulded wooden boat with epoxy-glass outer skin. I have not heard the noise from within a steel hulled boat, but I have from within a glassfibre boat. I assume this is because I haven't spent much time in metal boats. The noise is not very high frequency by standard human measures, almost exactly what I make by making a clicking noise in my mouth; and the best description is clicking - certainly each sound is not a scrape (ie, each noise is short); I mentioned explosive bubbles because that really is the best description. Like having a champagne supply under the boat. Keith Williams
