Looking at this photo reminds me that there used to be a 'liquid chocolate' vessel that frequently carried 'sludge' or 'city waste' out to the Bristol Channel spoil grounds. I think it was called Glen Avon. did you ever get any photos of her Malcolm? I remember seeing the two sludge vessels on the Clyde that did a similar job but also gave trips "doon the watter" for the OAPs of Glasgow. Did Glen Avon carry passengers on day trips?
