Fittingly, “fathom” is derived from the Old English word “fæthm,” meaning outstretched arms. The length of rope that reached across a sailor's extended arms was equal to one fathom. Sometime during the twelfth century, one fathom was officially defined as six feet.
The longest of many units derived from an anatomical measurement, the fathom originated as the distance from the middle fingertip of one hand to the middle fingertip of the other hand of a large man holding his arms fully extended. The name comes from the Old English faedm or faethm, meaning outstretched arms.
A fathom is a unit of length in the imperial and the U.S. customary systems equal to 6 feet (1.8288 m), used especially for measuring the depth of water.
Water depths are measured by soundings usually acquired by hydrographic surveys. The depths may be in either feet or fathoms (the chart will indicate which). A fathom is a nautical unit of measurement and is equal to six feet .
It is used as a standard unit of measurement in various countries' nautical charts, allowing sailors to identify water depths on the chart and calculate navigational hazards. Fathoms are also used to measure the draft of a ship – the distance between the ship's keel and the water line.
The term knot derives from its former use as a length measure on ships' log lines, which were used to measure the speed of a ship through the water. Such a line was marked off at intervals by knots tied in the rope. Each interval, or knot, was about 47 feet (14.3 metres) long.
Essentially, a cruise ship stays upright because they keep all of the heaviest equipment -- like the engines and whatnot -- below deck. This has the effect of keeping a low center of gravity and keeping the ship upright during unfavorable weather conditions.
A nautical mile is based on the circumference of the earth and is equal to one minute of latitude. 1 nautical mile = 1.1508 statute miles or 1.852 kilometers.
The significance of 12 nm derives from the fact that the U.N. Convention on the Law of the Sea (UNCLOS) generally grants coastal states jurisdiction over a 12-nm territorial sea emanating from the coast.
What is it: 12 nautical miles (from baselines) is the limit of the Territorial Sea (defined in the Territorial Sea Act 1987) which is that part of the sea adjacent to the coast of a state that is considered to be part of the territory of that state and subject to its sovereignty.

How Many Feet in a Mile? Why a Mile Is 5,280 Feet | Reader's Digest.
And if you're wondering, a fathom is equal to 6 feet. It's an old nautical term used to measure the depth of water. So 45 fathoms is 270 feet.
By the 1600s fathom had taken to the seas, as the verb was used to mean "to measure by a sounding line." At the same time, the verb also developed senses synonymous with probe or investigate, and it is now frequently used to refer to the act of getting to the bottom of something, figuratively speaking.
I know that a fathom is a unit of measure used by sailors, but how long is a fathom? A fathom is a unit of length used to measure the depth of water or the length of nautical rope or cable. A fathom is six feet, or 1.8288 meters.
20 fathoms (or 120 feet). “Fathom” can also mean gaining an understanding of a difficult problem on the path to solving it. And in Old English, “fathom” meant “outstretched arms” which is how it became a unit of measurement.
Australia has an Exclusive Economic Zone (EEZ) that extends beyond the 12 nautical mile territorial sea to a distance of 200 nautical miles (one nautical mile is internationally defined as 1.852 kilometres) in most places.
The international nautical mile is used throughout the world. The measurement was officially set at exactly 1.852 kilometers in 1929 by what is now known as the International Hydrographic Organization.
The oceans have no apparent surface features -- just a flat, vast, briny expanse. They're also all connected; the world's five oceans are technically one single ocean that covers 71 percent of the planet [source: NOAA]. This makes it difficult to divide, and so ultimately, you own the oceans.
So, for example, if your cruise ship is traveling at 20 knots (kn), that means it is going 23 miles per hour. What about 10 knots to mph? That's 11.5 mph. And 100 knots to mph: 115.
In 1592, Parliament wanted to standardize the measurement of the Mile and made the decision that it should be equal to eight furlongs. Furlongs, which are still used as a unit of measurement in horse racing, are 660 feet long. 660 times eight equals, you guessed it, 5,280.
The biggest reasons the U.S. hasn't adopted the metric system are simply time and money. When the Industrial Revolution began in the country, expensive manufacturing plants became a main source of American jobs and consumer products.
Typically the jail onboard is below deck in the marshaling area where provisions are loaded or somewhere along I-95 (the route that runs through the middle of the ship). However, cruise lines don't use the onboard jail as much as they used to. Instead, many lines will confine guests in their cabins.
A ship which has a large weight displace a large volume (thus large weight) of water. Hence the buoyancy force acting on the ship is much greater than the weight of the ship itself, making it to float on water. Thus ship do not sink in water.
