 | Note: Current WikiProject Ships consensus is that year categories be established for years from 1740 to the present only. Prior to 1740, ships should be categorized by decade (ships launched from 1600 to 1739) or century (ships launched before 1600) only. |
This is a template designed to be placed on category pages of the form [Decade] ships, like Category:1820s ships
Usage edit
Place {{cathead ship decade|decade year}} at the top of a decade category, where decade year is a year ending in zero (0).
