Image description

The image shows a small floating vessel, built of wood, without a deck, set in motion by the side oars, facing left.

At the top, the boat is viewed from above, and has an elongated shape, slightly domed on sides, meaning up and down, and narrowed to the top left, where it becomes sharp.

The right side of a boat is called starboard and the left side is known as port.

It has the back side at the edge, straight, in a vertical line, and here is located the lower part of the boat, called the stern and rendered by the texture of horizontal and parallel lines.

In the center are two wooden beams or rectangular, vertical boards, filled with the texture of horizontal and parallel lines, where the rower sits.

The left edge, where the front is, called the bow of the boat, is highlighted by a triangle with the tip to the left, textured with horizontal and parallel lines.

At the bottom of the image, the boat is illustrated from side, facing left with its front or bow and with its body called the hull highlighted by the texture of horizontal and parallel lines.

A man is standing in the left side, thus positioned to facilitate the comparison of the dimensions of the boat to the height of an adult.

Additional data

The boat is a floating vehicle of small dimensions, without deck, intended for the transport of people and materials, over short distances, in ports, on rivers and lakes. It is driven by rows, sails or motor. In some (rescue) boats the propeller propulsion is used, operated by a mechanical device, manually operated or with the feet, by pedals, as by bicycle.

The boat is made of wood, metal or other materials and is used for a variety of purposes: to save passengers from ships sinking after a shipwreck, fishing, sporting and leisure activities and trade.

The first man’s boats were rudimentary constructions, obtained by digging logs. The need for stability led to the emergence of floats, which were initially used on lakes or inland rivers. The floats were made of trunks or reed bundles connected with leather straps or straps. These were widespread on the Nile in 4000 BC in Egypt.

The first boat in the world discovered by archaeologists was the boat from Dugout dating from 6300 BC. In 1200 BC. Hr., The Phoenicians and Greeks built larger and improved boats for the purpose of gaining military supremacy or for transporting goods. Nearly 100 BC, the Romans built the largest commercial boats of their time. They were 180 meters long and 45 meters wide. They could carry 1000 people and 1000 tons of freight.

In 1886, the Romanian Alexandru Ciurcu and the French Just Buisson set up a boat for the first time using a jet engine, on the river Seine, against the current.
