History Of Ships

History of ships in line with the human adventure. The boats are known for the first time during the Neolithic dikenala, about 10,000 years ago. This initial ships have a limited function: they can move on the water, but nothing else. Primarily used for hunting and fishing. The oldest canoe found archaeologists are often made from coniferous trees, using simple stone tools.

Ship, are of passenger and goods transport at sea (rivers etc.) as well as canoe or smaller boat. Ships are usually large enough to carry a small boat like the boat. While in terms of english, separated between the larger ship and a smaller boat. By habit ship can carry a boat but the boat can not take the boat. Actual size in which a boat called the ship is always determined by the laws and regulations or local custom.

Over the centuries, the ship used by humans to navigate the river or the ocean that begins by the discovery of the boat. Usually people in the past using a canoe, raft or boat, the greater the need will then be made to fit the power boat or from larger vessels called. The materials used for shipbuilding in the past to use wood, bamboo or papyrus rods like the ancient Egyptians used people and then used metal materials such as iron / steel because the human need for a strong ship. For human propulsion are initially using the paddle and then with the help of the wind screen, after a revolution of the steam engine and diesel engine industries as well as nuclear. Some research has led to a walk-engined boat floating on the water like a hovercraft and Eakroplane. And vessels used in the bottom of the ocean submarines.

Centuries century ships used to transport passengers and goods until the early 20th century found an aircraft capable of carrying goods and passengers within a short time the ship had got heavy competition. But for the ship still has the advantage that is capable of transporting cargo by tonnage is higher so more ships are dominated passenger ships and tankers, while many are diverted into a cruise ship like the Queen Elizabeth and Awani Dream.



Navigation

To determine the direction, the ship sailed past not far from the continent or mainland. However, in accordance with the development of the crew members finally use the stars as navigational aids with tools such as the astrolabe and the compass and map. The discovery of an hourglass by the Arabs also helping navigation coupled with the discovery of clock by John Harrison in the 17th century. The discovery of the telegraph by SFB Morse and radio by C. Marconi, especially over the use of radar and sonar found in the 20th century made the role of navigator somewhat displaced. Unit is computed by knots boat speed in which a knot = 1.85200 km / hr.

Toward the end of the 20th century, navigation is made easier by the GPS, which has a very high accuracy with the help satelit.Selain from it a very modern communications systems also support navigation by the existence of several kinds of equipment such as radar-type Harp enables the navigator / first mate could see the direct state of marine conditions. Radar harp is a modern radar that can detect the distance between the vessel ship, ship to the mainland, ships with dangerous areas, boat speed, wind speed, accuracy and power have a clear picture. Aside from that there are more system GMDSS (Global Maritime Distress Safety System) A global shipping safety system. If a ship is in dangerous condition of this system will transmit the news that contains the danger of the ship's position, name of ship, type of danger, it is automatically, quickly, precise, accurate. For other communications systems are Inmarsat (International Maritime satellite) A system of sending information using E-Mail, Telephone, Telex, or Faximile.
