What is shipflag?

A ship flag, also known as a maritime flag or ensign, is a symbol representing a ship's nationality or affiliation. It is flown from the masthead, or flagpole, on a ship and is used to communicate important information to other vessels, such as the ship's country of origin, its status as a military or civilian vessel, and whether it is undergoing repairs or in distress.

Different countries have their own distinct ship flags, often featuring unique colors, symbols, or designs that represent national or cultural identity. Most ship flags are rectangular in shape, although some may have different proportions or shapes depending on their purpose.

In addition to national flags, ships may also fly other flags such as signal flags, which are used to communicate messages in code, and courtesy flags, which are flown to show respect for the laws and customs of a foreign port. The rules and regulations governing the use of ship flags are established by international maritime organizations such as the International Maritime Organization (IMO).
