 As the boat returned to the "Gnat", the crew sent the semaphore message "Judy's christening completed".The crew began to find the dog useful in navigating the river, as she was able to alert them to cess boats in sufficient time to close all hatches and minimise the smell.After undergoing trials following a refit, the "Gnat" met up with the "Ladybird", who also had a ship's dog.
