House flags (shipping)

Jump to navigation Jump to search

Merchant ships often fly a flag identifying which company owns the vessel. This was formerly flown from the mainmast but is now usually flown from the jackstaff.

Note! Not every company can be precisely assigned a nationality. Companies could be founded in more than one country at a time, be taken over by capital from another country, or be just branches of a larger company. On this website, companies are assigned to countries according to the cities in which they were founded and/or had their first headquarters.
