Why Must Ships Carry a Collection of Flags Onboard?
Flags are representative symbols of nations, provinces, cultures, communities, and groups. Whether in fabric form, through graffiti, or in digital formats, these insignias serve as signals or ornaments to distinguish a group of people who share a common belief or sentiment.
While their traditional use focuses on expressing a sense of belonging, flags gain additional relevance as means of communication in environments where verbal expression is not feasible. Over history, an extensive set of standards has developed that forms a true language of symbols. This terminology is so broad that it has even given rise to a specialized discipline: vexillology.
In maritime contexts, these distinctions play a crucial role as tools to convey messages. This formality is not new; it has historical roots, as maritime transport has always represented a politically, socially, and culturally significant means.
What Are Flags Used For on Ships?
Every ship must carry an assortment of signal flags onboard to be used when needed. These flags - known as nautical signal flags - serve to convey specific messages to other vessels or maritime authorities. Each one represents a letter or meaning, and by combining several, complex notifications can be created:
- Communication between ships: Signal flags allow vessels to express their identity and intentions on the water to others.
- Requesting assistance: Lack of communication can be a significant problem at sea if technical difficulties arise. A specific combination of these elements will help in requesting emergencies.
- Signaling to port authorities: Maritime jurisdiction has rules that differ from land. For this, there are insignias that serve to alert authorities regarding the ship's status, request services, or provide relevant information.
- Nautical events and ceremonies: There are various rituals celebrated exclusively at sea, such as fishing competitions or weddings. For these special occasions, flags are available to notify about the events in question.
History of Nautical Signal Flags
From small vessels to large cruises, flags are crucial for communication on the ocean. The history of these insignias has deep roots, as through various means, humans have always sought ways to express themselves.
One of the earliest records dates back to the Middle Ages, when flags were used to indicate the identity of the ship and its captain. A prominent example is the pirate ships that displayed skulls, a common representation of death at that time.
Over time, more flags were introduced that conveyed information about the nationality, function, or status of the ship. However, it was not until the 19th century that formal codes of international nautical signals, including the International Code of Signals (ICS), were established, adopted by the International Naval Conference in 1855 and revised in 1930.
Despite innovations and new forms of communication today, ships are still required to have a collection of these elements available for emergencies.
