You may or you may not be aware, but the WBE feature Migration Category Helper, which is enabled by default, allows you to easily create migration categories, as you can see in a part of the Germany Project's presentation during WikiTree Day.
With the March stable version v1.15, it also helps creating ship categories by adding hopefully appropriate parent categories. Besides from categories containing "(Ship)", it will also recognize categories as ship categories, if they contain brackets and a year, like "(1781)", which then is interpreted as year of launch.
In case you experience problems creating categories with a year, that do not belong to a ship, simply remove the code WBE inserted, by what you orignally had in mind. If this happens more often, please tell me, so I can check if I can exclude some patterns.
If you work on profiles whose ship of emigration is known (or one that was important for their life in any other direction), please try to assign a ship category. If you don't find a matching ship category or have doubt that the one exising is about the right ship, please create one. Always make sure, your ship category is at least part of Category: Ships by Name.
If you can't find the year of launch, then just create it as "(Ship)". It's easier to later separate passengers from conflated ship categories, then finding them ever again (especially, if they came with some ship named New York, Detroit, Berlin etc.) It would be really tough to find these profiles again later, so please assign them a ship category, when you already work on them.
Update: There really was a mistake in the recognition of four digits in parentheses, that currently leads to some false positives. It will be fixed soon, thanks for your patience. This has been fixed in v1.15.0.8. Unfortunately that version doesn't work with (Ship) anymore ... we're working on it.
