International Maritime Signal Flags
International maritime signal flags are various flags used to communicate with ships. The principal system of flags and associated codes is the International Code of Signals. Various navies have flag systems with additional flags and codes, and other flags are used in special uses, or have historical significance. Usage There are various methods by which the flags can be used as signals: * A series of flags can spell out a message, each flag representing a letter. * Individual flags have specific and standard meanings;AB Nordbok. "The Lore of Ships", page 138. New York: Crescent Books, 1975. for example, diving support vessels raise the "A" flag indicating their inability to move from their current location because they have a diver underwater and to warn other vessels to keep clear to avoid endangering the diver(s) with their propellers. * One or more flags form a code word whose meaning can be looked up in a code book held by both parties. An example is the Popham numeric ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Morse Code
Morse code is a method used in telecommunication to encode text characters as standardized sequences of two different signal durations, called ''dots'' and ''dashes'', or ''dits'' and ''dahs''. Morse code is named after Samuel Morse, one of the inventors of the telegraph. International Morse code encodes the 26 basic Latin letters through , one accented Latin letter (), the Arabic numerals, and a small set of punctuation and procedural signals ( prosigns). There is no distinction between upper and lower case letters. Each Morse code symbol is formed by a sequence of ''dits'' and ''dahs''. The ''dit'' duration is the basic unit of time measurement in Morse code transmission. The duration of a ''dah'' is three times the duration of a ''dit''. Each ''dit'' or ''dah'' within an encoded character is followed by a period of signal absence, called a ''space'', equal to the ''dit'' duration. The letters of a word are separated by a space of duration equal to three ''dits'', ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Distress Signal
A distress signal, also known as a distress call, is an internationally recognized means for obtaining help. Distress signals are communicated by transmitting radio signals, displaying a visually observable item or illumination, or making a sound audible from a distance. A distress signal indicates that a person or group of people, ship, aircraft, or other vehicle is threatened by a serious or imminent danger and requires immediate assistance.Aeronautical Information Manual U.S. Federal Aviation Administration, 2016 Use of distress signals in other circumstances may be against local or .

Royal Navy
The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is consequently known as the Senior Service. From the middle decades of the 17th century, and through the 18th century, the Royal Navy vied with the Dutch Navy and later with the French Navy for maritime supremacy. From the mid 18th century, it was the world's most powerful navy until the Second World War. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superiority globally. Owing to this historical prominence, it is common, even among non-Britons, to ref ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Diver Down Flag
A diver down flag, or scuba flag, is a flag used on the water to indicate that there is a diver below. Two styles of flag are in use. Internationally, the code flag alfa/alpha, which is white and blue, is used to signal that the vessel has a diver down and other vessels should keep well clear at slow speed. In North America it is conventionally red with a white stripe from the upper left corner to the lower right corner. Purpose The purpose of the flags is to notify to any other boats to steer clear for the safety of the diver and to avert the possibility of a collision with the dive boat which may be unable to maneuver out of the way. Signal flag Alpha As a code signal the International maritime signal flag Alpha (or "Alfa", signifying the letter "A") has the meaning of "I have a diver down; keep well clear at slow speed", used to indicate the presence of a diver in the water and is used in all countries other than the United States, Canada, sometimes Italy, and countries ...

Blazon
In heraldry and heraldic vexillology, a blazon is a formal description of a coat of arms, flag or similar emblem, from which the reader can reconstruct the appropriate image. The verb ''to blazon'' means to create such a description. The visual depiction of a coat of arms or flag has traditionally had considerable latitude in design, but a verbal blazon specifies the essentially distinctive elements. A coat of arms or flag is therefore primarily defined not by a picture but rather by the wording of its blazon (though in modern usage flags are often additionally and more precisely defined using geometrical specifications). ''Blazon'' is also the specialized language in which a blazon is written, and, as a verb, the act of writing such a description. ''Blazonry'' is the art, craft or practice of creating a blazon. The language employed in ''blazonry'' has its own vocabulary, grammar and syntax, which becomes essential for comprehension when blazoning a complex coat of arms. Ot ...

Flag Semaphore
Flag semaphore (from the Ancient Greek () 'sign' and - (-) '-bearer') is a semaphore system conveying information at a distance by means of visual signals with hand-held flags, rods, disks, paddles, or occasionally bare or gloved hands. Information is encoded by the position of the flags; it is read when the flag is in a fixed position. Semaphores were adopted and widely used (with hand-held flags replacing the mechanical arms of shutter semaphores) in the maritime world in the 19th century. It is still used during underway replenishment at sea and is acceptable for emergency communication in daylight or using lighted wands instead of flags, at night. Contemporary semaphore flag system The current flag semaphore system uses two short poles with square flags, which a signal person holds in different positions to signal letters of the alphabet and numbers. The signaller holds one pole in each hand, and extends each arm in one of eight possible directions. Except for in the re ...

Flag Of Finland
The flag of Finland ( fi, Suomen lippu, sv, Finlands flagga), also called ' ("Blue Cross Flag"), dates from the beginning of the 20th century. On a white background, it features a blue Nordic cross, which represents Christianity. The state flag has a coat of arms in the centre but is otherwise identical to the civil flag. The swallow-tailed state flag is used by the military. The presidential standard is identical to the swallow-tailed state flag but also has in its upper left corner the Cross of Liberty after the Order of the Cross of Liberty, which has the president of Finland as its grand master. Like Sweden's, Finland's national flag is based on the Scandinavian cross. It was adopted after independence from Russia, when many patriotic Finns wanted a special flag for their country, but its design dates back to the 19th century. The blue colouring is said to represent the country's thousands of lakes and the sky, with white for the snow that covers the land in winter. This ...
