ответ:Since ancient times, ships have been used to transport people and goods across seas and oceans. Even in the modern world, with the presence of aviation and cosmonautics, ships, as before, remain the most important means of transport for passenger transportation and maintaining trade. In addition to cargo and passenger ships, warships have always been needed to ensure the safety of Maritime trade routes. Since the times of Ancient Egypt, Ancient Greece and Ancient Rome, the power of the Navy has created and destroyed entire empires. This book describes the most significant stages in the development of shipbuilding since ancient times, Since many types of ships have been improved over time to show the diversity of the same type of ship, we often present several types of it.

From 2500 BC to 1500 ad, ships were propelled by oars and sails. From 1630 to 1850, the most powerful warship was a three-deck wooden sailboat, which had 100 or more guns on Board.
The crew of a warship of the XVIII century consisted of 850 officers and sailors. Positions at that time: captain, Lieutenant, Midshipman, sailor, gunnery officer, gunpowder boy. The crew of a modern passenger ship consists of people of various professions: navigators, computer operators, motor mechanics and, of course, good cooks! Positions in our time: captain, nurse, Navigator, mechanic, radio operator, cook.
Modern passenger liners have comfortable cabins, cinemas, restaurants, swimming pools and play areas for children. Great importance is attached to security measures. In the old days, sailing on ships was very dangerous.
