5. is the tenth anniversary ofthe British Shipping Federation's ban on the keeping of animals such as dogs or cats as pets on British registered vessels. In 1977 the keeping of a dog or cat as a pet on board ships of the home fleet was also banned by the Royal Navy, (apart from HMS Belfast which is moored permanently in the Thames). From time immemorial ships have had cats and/or dogs on board, not just as pets but also to keep down vermin and occasionally to act as guard dogs; but the fear of introducing rabies into Britain brought about the ban. I wonder ifrabies could have played a part in one of the great sea mysteries of over 100 years ago?
