A ship that sails mainly by wind. Its main propulsion equipment
Set it as a sail, and use paddles, paddles and poles as berthing, sailing and sailing.
Auxiliary propulsion device for wind navigation and weak wind navigation. Inland sailboat
And fiber tools. When sailing against the current without wind, the fiber worker goes ashore and walks on his back.
Pull the boat forward. Sailing boats are distinguished by the number of masts that hang sails, including single-masted ships and double-masted ships.
And a multi-masted ship; According to the purpose, there are transport ships, ferries, fishing boats and
Tourist boat. In ancient times, there were warships dedicated to combat. In addition, it also
There are sailboats dedicated to water sports. Sailing boat is an ancient means of water transportation.
Vehicles appeared at least 5000 years ago. Types of ships There are many types of sailboats in the world. Depending on the type of bottom, it can be roughly
Divided into gondolas and sharp-bottomed boats; According to the first type, there are wide-headed ships and narrow-headed ships.
Bow boats and pointed boats, pointed boats are also generally pointed tails, with fore and aft side arcs.
Bigger. During the Song, Yuan, Ming and Qing Dynasties in China, coastal sailboats were divided into four parts.
Class: flat-bottomed "sand boat" mainly sailing in the Yellow Sea; Fujian's tip
Bottom "lucky boat"; Guangdong's "Guang Chuan" (similar to Fu Chuan, but better than
Lucky boat is strong and big); A small area along the coast of Zhejiang, Fujian and Guangdong.
Type a quick "bird boat". In inland rivers, it spread from the Spring and Autumn Period and the Warring States Period to the Ming Dynasty.
The Large Warship "Louchuan" in Dai Dynasty and Song, Yuan, Ming and Qing Dynasties
Represents a flat-bottomed "oil tanker" dedicated to transporting grain in the canal. Sailing boats usually
It is a single hull, but there are also catamarans, that is, two hulls are juxtaposed and kept.
At a certain distance, the front and back are connected and fixed by several beams. binary
The ship has strong wind and wave resistance, and the catamaran of the South Pacific island has been
World-famous. Hull structure sailboats are usually made of wood. The skeleton is mostly horizontal.
Skeleton type, including transverse members such as bent ribs, foot beams and face beams.
Only larger wooden boats have longitudinal bottom pressure bars and side pressure bars. The partition not only
It is used to separate the cabin and is an indispensable part of the skeleton. Chinese purple sugar
Watertight cabin is used to improve the sinking resistance of hull. shell
The plate is mainly composed of longitudinal members such as bottom plate, stern plate, body plate and side deck.
Composition. The skeleton supports the shell plate, and together with the shell plate forms a certain
Strength and rigidity of main hull. The keel of a sailboat is a set of bottom plates.
Part, the outer side protrudes below the bottom of the ship. Gondola's keel has one.
There are several roads, and the prominent part is round back. Sharp-bottomed ship in the longitudinal direction
The line is provided with a square keel protruding from the bottom of the ship, which can not only improve the longitudinal direction of the bottom of the ship
In addition to lateral strength, it also plays a role in preventing the lateral drift of the hull when driving in crosswind.
Use. Some large Chinese sailboats have two or three hulls.
Slab structure, some use double bottom, inner bottom and outer bottom.
Spacing cross leg beam. The upper part of the body board is usually some logs.
Split the round back thick plate to strengthen the longitudinal strength. Hull plate joint
Compacting with a mixture of tung oil lime and hemp fiber or bamboo fiber; Ancient Arabia
Ships and wooden boats in tropical Pacific islands use olive resin, bark and leaves.
Boil it into jelly shape and twist it; Pirate ships also twisted seams with moss; the Mediterranean Sea
Some ancient ships along the coast are twisted with animal hair and textile materials, and then coated and drained.
Green. The rigging consists of a sail, a mast for hanging the sail and a rope system for manipulating the sail.
Sailing boats are mostly single-masted, double-masted and three-masted, which are giant sailing boats in ancient China.
Having as many as seven masts and nine masts. The mast is usually placed along the longitudinal centerline of the ship.
The main mast in the middle is the longest and thickest, and its length is about equal to or less than that of the captain.
The head mast and the tail mast are short in turn. A sailboat with more than three masts besides the main sail.
Outside the center line, the front mast and the rear mast are arranged on two sides or both sides of the center line, and each
The sail cooperates with the wind and does not interfere with each other. Primitive sailboats usually use square sails with four corners, one in the south of China.
In some inland rivers, there are still four-corner sailboats with herringbone masts. Later chase
Step evolved into a rectangular sail with four corners and a triangular sail with right angles, which can be deflected.
The wind. Some modern sailboats use jibs, while others use square sails. double；twofold
Mast ships and three-masted ships can use these two kinds of sails. Chinese sailboats use four
The main sail is angle sail, mostly rectangular with inclined top, and there are many cross rods on the sail surface.
Hard sail; Some coastal sailboats have a sharp corner at the top of the sail.
Both sides are arc-shaped, and the whole sail surface is fan-shaped. When raising the sail, the mast is at
Between the front side of the sail and the longitudinal centerline. The semi-equilibrium of this sloping top edge
Sail control is flexible, and the wind pressure center on the sail surface is low, which is beneficial to yaw.
Some Chinese sailboats also have triangular soft sails. Sailboats in the upper reaches of the Yangtze River
In sail before the wind, a right-angled triangular auxiliary sail was hung in front of the main sail.
The bottom edge is flush with the main sail and is equal to the extension length of the main sail. The length of the sail is adapted to the length of the mast, and the width of the main sail is greater than that of the ship.
The size of the head sail and the tail sail decreases in turn. The main sail width of Chinese sailboats is as follows
More than twice the width of the ship. Total sail area (square meters) and ships
The full-load displacement (in tons) has a certain empirical proportional relationship.
Chinese sailboats are generally between 2: 1 and 3: 1.
