Pages in this category should be moved to subcategories where applicable. This category may require frequent maintenance to avoid becoming too large. It should directly contain very few, if any, pages and should mainly contain subcategories.
This category's sub-categories include all articles on individual ships, a loose category that overlaps considerably with boats, the distinction being a matter of local laws or traditions, or even personal opinion. Category:Boats is included as a sub-category of "Ships by type" for vessels often considered as boats.
