Biography of catamarans

Such different catamarans are called catamarans, which have two parallel buildings of the same size. Such a structural solution significantly increases the stability of the catamaran to rolling and overturning on the water. Also, such vessels have smaller volume, displacement and sediment compared to single -string. According to experts, a similar design allows you to reduce hydrodynamic resistance, which means that the movement will require less sails or not so powerful engines.

There are many varieties of catamarans - from small sailing boats to boat and ferries. The beach catamaran rolled vacationers along the park lake. Yachtsmen go sail at sea. And the Volga waves dissect the Catamarana boat. The design of catamarans can also be very different, depending on the type and size of the vessel: from a simple frame connecting two buildings to a full -fledged vessel with a large number of rooms and a cargo compartment.

On the rivers you can find small vessels and large motor ships - and all of them will be catamaran. Photo Fleetphoto. Author: Orion on logs to conquer the ocean the word "catamaran" comes from the Tamil "cattumar", which means "tied logs". Tamil is one of the most ancients on the planet, is included in the list of state -owned language of India. At its core, ancient catamarans were rafts built from the connected trees.

Some researchers call the inventors of the ships of this type of ancient fishermen Madras on the southern coast of India, others are Austronism peoples from Southeast Asia, and present Indonesia.

Drawing of boats from Fiji, G. Louis Le Breton drawing boats from Fiji, G. Louis Le Breton Indians knitted light and stable sailing rafts from an odd number of three to nine logs. The central log is thicker than the rest, the nasal end is pointed and slightly bent up. The remaining logs are attached to the middle so that the bow of the raft is pointed, like the pies. The Dutch merchant and artist Isaac Gilsemans, joining the expedition to New Zealand and the islands of the Pacific Ocean - GG.

It was two -related canoeing. This ship was made using the technology of the minimum raft from the connected logs. Later, the design of archaic catamarana from two -body canoe evolves into an asymmetric vessel, where one building is smaller than the other, and then into a single, with two remote supports. Despite all the simplicity, such a “ship” allowed ancient people to move between the islands of Indian and Pacific Oceans.

According to historians, the early catamarans reached a length of 21 m. They were used for a variety of purposes - moving between the islands, fishing, etc. As soon as the ancient catamarans put a sail, the distance that such a vessel could have increased to almost 3.7 thousand. Polynesian catamaran - the drawing of Isaac Gilsemans from the diary of the expedition of Abel Tasman.

Enterprises in the catamarans, European sailors, after meeting with natives, decided to adopt their experience in building catamarans. The first two -corps sailing ship designed William Petty in the year. It could develop a decent speed in shallow water, even with a weak wind and did not require a large crew. This experience was documented, but did not gain distribution.

The catamarans were remembered only in the 19th century, when the Englishman Maiflawer Cripus built a two -body trading ship called Original. After that, interest in this type of ships grew rapidly. So, in June, the American Nathanael Herreshoff built a two -corps sailing boat of his own design and received a patent. The catamaran participated in the regatta and showed excellent results.

And in the gg. Catamaran “Rest” Four -decking motor ships “Rest” were intended to perform local passenger transportation and one -day tourist flights of short duration along the Volga. The relatively small sediment of the catamaranov gave them the opportunity to easily overcome shallow places, come close to the shore and make “green parking”. In the scientist, together with the employees of the Department of Theory of the Ship, the Gorky Institute of Water Transport Engineers and the Gorky Central Design Bureau of the Minrechflot conducted experiments to develop new forms of corps.

Professor Alferiev with colleagues found that two buildings connected by one platform when moving at high speed do not form waves. They slide through the water, like running skates on ice. Alferiev called this discovery "a catamaran effect." In the two buildings of the vessel, there were rooms for the crew, pantries, containers for fuel and water. The energy installation of the ship consisted of two main engines with power in l.

To relax passengers, a large upper deck was provided, which was an open terrace. For landing to the shore where there were no marinas, the ship is equipped with a special ladder with a hydraulic drive. The ship walked along the Volga up to a year.Professor Alferiev also designed the high -speed catamaran "Anatoly Uglovsky", designed to transport passengers in shallow water, small and large rivers.

The ship accommodated the passenger and was equipped with cabins by type of compartment. In addition, Alferiev developed a catamaran for intracity and suburban Volga lines. But they did not go into the series. The high -speed catamaran "Anatoly Uglovsky" can still be found on the Volga. By the way, in honor of Mikhail Yakovlevich, the Katamaran-Sukhload “Professor Alferiev” was named-a dry-loaded two-and-chase ship with a carrying capacity of tons.

The housings are connected by a hard bridge, the vessel has an open cargo deck and a bunk superstructure. The catamaran transported containers and other deck goods. With two main engines, the power of l. And today, catamarans are again running along the Volga - the latest electric passenger vessels built in the Leningrad Region. Electric power plants with a power of kW each are driven into the catamaran.

So catamaran -building in Russia has a glorious past and a great future! Read also:.
