A sailboat is a boat that uses the wind to move forward.
Sailing originated in Europe and its history can be traced back to ancient times.
Sailing is a witness of mankind’s struggle against nature. Sailing has a history as long as the history of human civilization.
The earliest written record of sailing as a racing event can be found in the works of the poet Virgil more than 1,900 years ago.
By the 13th century, Venice had begun to hold regular sailing races. At that time, there was no uniform size or class of racing ships.
The actual distance a yacht travels in a race.
Both the World Sailing Championships and the Chinese Sailing Championships use short – distance triangulated sailing.
The triangulated range is arranged by three buoys in an isosceles triangle of 45 degrees, 90 degrees and 45 degrees.
The length of the course between the two buoys is not less than 2-2.5 nautical miles, equivalent to 3.7-4.7 km, and its straight-line race range is about 28 km.
The RACE ORDER OF the whole voyage IS to sail around MARK 1, 2 and 3, then round mark 1 and 3 to reach the end point, and the race order of the shortened voyage is to sail around mark 1, 2 and 3 to reach the end point.
The course and direction of the bidING are specified in the sailing rules of the race. All boats must sail and biding in accordance with the rules, otherwise they will be treated as having not completed the race.
A device in sailing waters used to indicate the course of a race.
The term used in sailing for the angle between the wind direction and the line between the end and end of a sailboat.
Sailing ships are powered mainly by the wind.
And the wind direction is crucial to how much the sail is used for propulsion.
Athletes must have the right Angle of the wind in order to make the most of the wind.
A variety of different wind direction Angle its distinction degree is: headwind wind direction Angle between 0 degrees -30 degrees;
The windward wind Angle is between 30 and 60 degrees;
The windward wind Angle is between 60 and 80 degrees;
The wind Angle of the cross wind is between 80 and 100 degrees;
The downwind Angle is between 100 and 170 degrees;
The wind Angle of the tail wind is between 170 and 180 degrees.
The name of the main installation on a sailboat.
A sloop has one mast and one sail, such as a mainsail — Kate’s sail was the mainsail.
On a ketch, one mast forward and one aft, with some mainmast in front, the Rueger and the Ketch.
Some aft mainmast, such as the Shihura.
It can be considered that the jib – Bermuda sail or large square sail – gaff sail is the main sail.
One of the main fittings on a sailboat.
A sailboat sails mainly by the wind, and the sail must be attached to the mast to sail far.
Masts are mostly made of hard logs or metal.
According to the size and needs of sailboats, there are sloop into sailboats and ketch.
Most sloop masts are located near the bow of the boat.
Ketch sails are generally used on larger sailboats with two masts, one in front and one in back.
In ketch ships there are fore – and aft – mizzen ships. The top mast of these ships is called the mainmast;
On another mizzen, the aft mast is called the mainmast.
port, “port,” sailing term.
The sides of a ship are called bulwarks.
The left side of the ship is called the “port side” as the stern looks forward to the bow.
port tack – Technical term for sailing.
The direction of sailing depends on the Angle between the longitudinal and vertical surface of the center of the hull and the wind, or on the Angle of the bearing of the sailboat.
When the wind blows from the left side and the mainsail is on the starboard side, a sailboat is on the port side.
starboard, “starboard,” is a sailing term.
The sides of a ship are called bulwarks.
The looking direction of the stern to the bow.
The starboard side of a ship is called starboard.
starboard tack Technical term for sailing.
The direction of sailing depends on the Angle between the longitudinal and vertical surface of the hull and the wind, or on the Angle of the boat’s bearing.
When the wind blows from the starboard side and the mainsail is on the port side, a sailboat is on the starboard side.
oars – a technical term for sailing.
Sailing relies primarily on the wind for propulsion, but paddles are also used when sailing offshore and back to shore.
When a sailboat is rowing, it will first lift up to the board, and then the water has little resistance to the boat.
In order to avoid the blade by the wave impact and reduce air resistance, in the process of rowing, the blade is used to turn the paddle with the wrist after hitting the water, so that the blade is parallel to the water surface, which is a flat paddle.
A device used by a referee to organize and direct a race in sailing.
The water area of the sailing competition is large, and the only way to organize the wind-powered sailing competition is to pass the command through the referee’s international flag and sound system.
Each of the flags of the judge ship is represented by a Latin letter in a different color and figure to indicate an instruction.
In the world, one flag or two flags are usually used to express the same meaning.
For example, the red flag indicates that the racing boat must go clockwise around the mark, the starboard mark.
The green flag indicates that racing boats must go clockwise around the prescribed mark, the port round mark.
The blue flag indicates the finish.
The draft, draught indicates the depth of the hull below the surface of the water.
Since the bottom of the hull is not necessarily parallel to the horizontal plane along the captain’s direction, the draft depth of each part along the captain’s side is also different.
The draft at the forward vertical line of the hull is called “forward draft” or “forward draft”, and the draft at the backward vertical line of the hull is called “backward draft” or “tail draft”.
The midpoint perpendicular to the length of the hull is called the “mean draft”.
gunnel suppr – Technical term for sailing.
When sailing, in order to make full use of sail area and strong wind to obtain greater sail power, on the one hand, the sailing according to the predetermined direction, but also to maintain the smooth sailing of the sailing, reduce the roll, then the crew can be distributed to the windward side, called the pressure side.
Sometimes in order to reduce the center of gravity of the ship, further increase the anti-heeling moment, as far as possible to make the athlete’s weight out of the ship for a longer distance, or even hang all the body overboard, called hanging ballast.
Special equipment, such as sling, handle, sling strap, seat cushion, hanging ring, hook, etc. should be provided to ensure the safety of athletes and achieve satisfactory results.
A technical term used in sailing to come about.
Athletes in sailing forward, if the head wind can not sail sailing, can use the windward sail technology, this technology is called windward sail.
raise start is a term used in sailing competitions.
According to the RULES of SAILING, A normal start must be when the athlete’s boat has passed the course after the referee’s start signal has been given.
If any part of the hull, equipment, or body of a competing boat touches the course or its extension before the signal to sail is given, it is a snatch.
The commandeers must return to the rear of their original course and set sail again.
If there are more sailboats to snatch.
When the JUDGES are unable to decide which boat is going to win, they may recall all boats in that class and start again.
bathom, a sailing term.
A nautical unit of depth, one stroke equal to six feet in length, usually measured on nautical charts.
set sail start, “set sail start.”
Sailing races are divided into three stages: starting, sailing and finishing.
Ten minutes before the start of the race, the judge’s boat raises the flag of a class on the transverse mast, indicating that the class has ten minutes to go.
Five minutes later, the JUDGE’s boat raises the “P” flag to signal that the class has five minutes to go.
After that, every minute, the sailing boats will be informed by sound signals in the order of 4, 3, 2 and l.
After THE START SIGNAL HAS been GIVEN, A racing BOAT WILL SET SAIL IF ANY PART OF ITS HULL, CREW OR EQUIPMENT TOUCHES THE COURSE IN THE COURSE LEADING TO THE FIRST buoy.
The race clock began.
A part of a sailboat that controls the direction of the sailboat.
There are two types of rudder of a sailboat: one is a fixed rudder with a rigid tiller;
The other is a lifting rudder with a split tiller.
Fixed rudders are mainly used in keel boats, while lifting rudders are usually used in steady board boats and flat boats.
A term used in sailing to release, to set free.
It means that the athletes regain the right to play after the corresponding “punishment” for violations in the competition.
For example, in the race, the athlete’s boat touched the mark, you need to round the mark again, can be released.
If an athlete’s boat touches another sailboat, he or she will spin 720″ on the spot to get rid of it, otherwise he or she will gain 20% of the ranking.
