compassA compass, which is used to assist in navigation, is an instrument that shows magnetic north. You must apply a correction to determine the direction of true north. The ability to steer a boat by a compass is useful if land is out of sight, visibility is reduced, or the boat operator is disoriented.
In 1764, British clockmaker John Harrison (1693–1776) invented the seagoing chronometer. This invention was the most important advance to marine navigation in the three millenia that open-ocean mariners had been going to sea.
The earliest navigation methods involved observing landmarks or watching the direction of the sun and stars. Few ancient sailors ventured out into the open sea. Instead, they sailed within sight of land in order to navigate. When that was impossible, ancient sailors watched constellations to mark their position.Jan 21, 2011

It is said that maps and charts are the most important part of any navigational aids.

To do this, Columbus used celestial navigation, which is basically using the moon, sun, and stars to determine your position. Other tools that were used by Columbus for navigational purposes were the compass, hourglass, astrolabe, and quadrant.
Constellations are groupings of stars that create recognizable patterns in the sky. … Because circumpolar constellations never rise or set, they provide reliable reference points for astronavigation. Knowing the circumpolar constellations in each hemisphere allows navigators to find their way using only the stars.Nov 27, 2021
The Mariners Compass Although early navigators still relied heavily on celestial navigation, compasses made it possible for sailors to navigate on overcast days when they could not see the sun or stars. Early mariners compasses were made by placing a magnetized needle attached to a piece of wood into a bowl of water.Jun 27, 2019

A sextant is a traditional navigational tool. It measures the angle between two objects, such as the horizon and a celestial object such as a star or planet. This angle can then be used to calculate the ship's position on a nautical chart. compass is a device that indicates direction.Apr 4, 2021

When you meet an oncoming vessel, and wish to pass port to port, you are required to sound one short blast with your horn. If the other boat is in agreement, they should respond with a similar blast.
If you approach another vessel head on, and wish to pass it on its starboard side , you are required to sound two short blasts with your horn. If the other vessel is in agreement, they should sound the same signal in response.
Sound signals are to be used only when vessels are in sight of each other and are meeting or crossing at a distance within half a mile of each other. These signals must never be used in fog or other conditions of reduced visibility, where the vessels are not visible to each other by eye.
There are thousands of equipment present onboard a modern-day ship. Several of these are relatively new and have made it easier for a pilot to navigate through the waters. Here is the list of different types of navigational equipment used onboard modern ships explained briefly.
An Electronic Chart Display and Information System or an ECDIS is a geographic system of information. It is used for nautical navigation. This system complies with the IMO or the International Maritime Organization. This system makes it easy for the crew of a ship to pinpoint different locations and get directions more easily than using the conventional nautical charts.
An ATA or an Automatic Tracking Aid is quite similar to an Automatic Radar Plotting Aid. This navigation instrument is also used for creating tracks with the use of radar contacts. It displays the information about the tracked objects in the form of numbers or graphics. This helps in creating a planned layout to make the course collision-free. An ATA allows manual acquisition and automatic tracking of multiple targets entering an acquisition area.
Speed and distance log device is a piece of navigation equipment used for measuring the speed and distance that the ship travels from a particular reference point. In this manner, it becomes easy to calculate the estimated time of arrival of the ship at a particular place and this time is conveyed to the port authority. It can also be used to adjust the ETA in case of any issue of traffic at the dock.
A wheelhouse poster is a poster that displays all the information about the maneuvering characteristics of the ship in great detail. It is present in the navigation bridge. Every ship nice to have a wheelhouse poster.
A Gyro Compass is a kind of compass used at the time of a sea voyage. Unlike ordinary compasses, a gyromagnetic compass does not get affected by an external magnetic field. It automatically finds a geographical direction based on the rotation of the earth. These compasses have two main advantages over magnetic compasses. Firstly, they find the true north which is more useful than the magnetic north for navigation. Secondly, they are not affected by other ferromagnetic material like the parts of the ship.
A magnetic compass is a navigation device used to find the northern direction with the help of the earth’s magnetic field. Magnetic compasses are the most commonly used type of compasses. The compass has a diagram on it that has the four direction that is North, East, West, and South marked on it.
Initially used only when the weather obscured the sun or the North Star, these first compasses were very crude . The navigator would rub an iron needle against a lodestone, stick it in a piece of straw and float it in a bowl of water. The needle would point in a northerly direction.
The first ocean voyages were probably big mistakes – a vessel blown off course by a sudden storm or error by the helmsman. The Vikings regularly sailed to Iceland and Greenland between 900 and 1000AD, apparently using only the sun, stars and wind as their guide.
In 1907 Elmer Sperry introduced the gyroscopic compass which is unaffected by variation or deviation as it points to true north, not magnetic north. British physicist Robert Watson-Watt produced the first practical radar ( ra dio d etection a nd r anging) system in 1935 .
In addition to its marine uses, it is also used for controlling air traffic, detecting weather patterns and tracking spacecraft.
Department of Defense . This space-based radio-navigation system consists of 24 satellites and provides accurate positioning to within about 30 feet as well as velocity and time worldwide in any weather conditions.
