Water transport was of greater importance than the communication by roads in ancient times. After 3000 BC, sailing ships of considerable size were evolved, phoenicians established a trading network in the mediterian. Indians established links with various countries in the south-east Asia by sea route. The Navy used to receive importance in all coastal countries but it received further impetus after the creation of a professional British Navy by Henry III and exploration of new lands by Spain and Portugal. R.Volturio gave illustration of boats (1483) with crank driven paddle wheels.

Shipbuilding and Marine Engineering got a big boost with the production of iron and steel and invention of the steam engine. Jonathan Bull patented a steam boat in 1737, from 1807 regular service with steam ships started.

Brunel, Napier, Robert are regarded as founder fathers of Marine Engineering. Brunel was the pioneer to use screw propulsion. The East India Company stimulated the growth of shipbuilding industry further. The steam turbine was installed in a ship in 1897 leading to more speed and economy. The Diesel Engine, Modern Turbines, Radio Communication, Satellite Navigation, Nuclear Power, Computer control. etc. have been progressively introduced in Marine Engineering as innovational steps.

Efficient transport by Sea is an important mode of transportation particularly for Countries with an outlet to the Sea. The Merchant Navy comprises passenger vessels. Cargo vessels Liners, Ore Carriers and other types of specialized ships. These ships are operated by private sector shipping companies and manned by trained highly paid Navigators, Marine Engineers and Crew.

A Career in the Merchant Navy means high income, greater independence and an exciting life style.
