HMS Titania is now in the Royal Navy Ships category. Thanks for all your help. My next question is this: The Royal Navy has various classes of vessel (incl. ships and boats), with designations such as HMS, HMY, RFA (Royal Fleet Auxiliary), RMAS (Royal Maritime Auxiliary Service), HMT (His/Her Majesty's Trawler), HMTB (His/Her Majesty's Torpedo Boat). They can't all go into the Royal Navy Ships category. Some people will object if boats are put in the ship category. Where should they go in the categories?
