What is the course of a sailing ship relative to the wind called?

Usually the course of the ship is determined by the angle between the plane of the meridian and the centreline of the ship, measured in degrees from the northern part of the meridian in a clockwise direction (from 0 to 360 degrees). However, on sailing ships, in addition to the usual, the determination of the course relative to the wind is used according to the angle between the direction of the wind and the centreline of the ship. Depending on the value of this angle, the ship's course receives various names: sidewind, gulfwind, backstay and jibe.

Badewind - the course of the ship, at which the angle between its diametral plane and the direction of the wind is 10-80 degrees starboard or port. There are close-hauled (angle 10-45 degrees) and full-hauled (angle 45-80 degrees).

A Gulfwind is a course at which the diametrical plane of the vessel makes a right angle or close to a right angle with the direction of the wind. About a ship sailing in Gulfwind, they say that it "goes at half wind."

Backstay - a course at which the angle between the diametrical plane of the vessel and the wind line is 90-180 degrees to starboard or port. There are a steep backstay (angle 90-135 degrees) and a full backstay (angle 135-180 degrees).

A jibe is the course of a ship that is in line with the direction of the wind. Sometimes a gybe is called a full wind, and a ship sailing in a gybe is said to be "going with full wind".

The name of the course of a sailing ship, in which the wind blows right in its nose, is not mentioned in marine dictionaries and encyclopedias, but this gap in marine terminology was filled by Captain Khristofor Bonifatievich Vrungel (the hero of Andrei Nekrasov’s story, beloved by many children), who proposed the name "vmorduwind".

Random interesting fact from the Great Encyclopedia:

What does Novus ordo seclorum mean on a one dollar bill?

Conspiracy theorists like to say that the one dollar bill and the Great Seal of the United States say "New World Order." In fact, the Latin saying "Novus ordo seclorum" is translated differently: "The new order of the ages." This motto was placed on the Great Seal to commemorate the independence of the United States and the beginning of a new era in American history.

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

ASUS PA32Q Professional 4" 328K Monitor 04.06.2014

Following the $28 4-inch 287K monitor PB800Q, introduced at the beginning of the year, the Taiwanese company ASUS is preparing to release another 4K model ProArt PA328Q, but aimed at professional needs.

The monitor has a 32-inch diagonal and the same resolution of 3840×2160 with an aspect ratio of 16:9. The screen is factory calibrated, has 10-bit transmission (1,07 billion colors) and 100% sRGB space coverage. It uses WLED backlighting, claims a brightness level of 350 cd/m---2, and a dynamic contrast ratio of 100:000.

There is one HDMI 1.4 port and one HDMI 2.0 compliant MHL 3.0, that is, capable of charging mobile devices, one DisplayPort 1.2, one Mini DisplayPort 1.2 and four USB 3.0. The stand allows you to rotate the monitor, tilt it vertically and horizontally, and adjust the height. The case has thin bezels and a small thickness at the edges.

Sales should start in the fourth quarter.
