Administrators: Please do not delete this category even if it is empty! This category may be empty occasionally or even most of the time.
Pages are placed in and removed from this category by placing the template {{ship}} with non-empty parameter builder on or removing it from them. Do not add pages to this category manually.
Maintenance: Search for misplaced files using PetScan (will not work on categories shared by many templates).
Experimental. This is added when {{ship}} includes a value at "builder=<name>, <locality>" with no corresponding category in the format "Ships built at <name>".
