So, in your mind, would a "reliable" database be the federal documentation maintained by the flag state?
That seems resonable to me. Those agencies in charge of such registries are in principle the authority for the documentation of every vessel bearing their flag. Such information would then be the official way that the flag state believes the vessel's name exists.
While it would be impossible to take a look at every single flag state database, seeing as many aren't accesible online, we can inspect some that are, such as those of
Canada and the
United States.
To get a good idea, I decided to pull up a name that would pull up well over 100 results. If the naming style is consistent throughout that sample, I feel it is safe to assume it is consistent throughout the entire database.
First for the Transport Canada query, I searched for all vessel name beginning with the word "star." That search brought up 123 results, and each one was entered in all caps. From this we can see that the Canadian government views the proper presentation of a vessel's name as capitalized.
For the Coast Guard Vessel Documentation search, I queried all names beginning with "snow." This time around, I received 196 results, again all spelled out in all caps. Thus, we come to the same conclusion for US flagged vessels.
The Australian Maritime Safety Authority provides a
list of registered vessels instead of a query. Once again, all listed names are in all caps.
Same thing for at least one flag of convenience, here's the list maintained by
The Bahamas Maritime Authority.
While this is only a small portion of the world's vessels are noted by this sample, I have noticed a trend. I did not leave any out, each and every country-maintained listing of ships I found shows vessels listed with names in all capitals.
So, if the reality is that individualism in tyopgraphy exists only on the ship's hull as a matter of owner's preference that could be changed on a whim, but officially the name is carried in capital letters, there exists a big argument for all names to be typed in accordance with the official documentation. Or, at this point, for at least all vessels flagged in Australia, The Bahamas, Canada, and the United States.
