1) Inland navigation: including Jiangsu section of the Yangtze River and Shanghai section of the Yangtze River.

A Jiangsu section of the Yangtze River: The Blueprint of the Yangtze River (Nanjing to Liuhekou) published by Shanghai Yangtze River Waterway Management Office is selected. Make the route according to the direction of the side mark of the main channel of the Yangtze River, that is, connect two buoys and read the route. The distance has been marked on the blueprint of the Yangtze River, which can be converted into the sea when making a navigation plan. The blueprint of the Yangtze River has timeliness, which can solve the problems of the Yangtze River waterway, changeable water depth and incomplete ship information, and has also been recognized by the maritime department.

B Shanghai section of the Yangtze River: the blueprint of the Yangtze River published by Shanghai Maritime Safety Administration (Liuhekou to Changjiang Estuary, divided into north and south troughs) is selected. The nature is the same as the blueprint of Jiangsu section of the Yangtze River, and so is the principle of making routes.

The established route should conform to the route system of Jiangsu section and Shanghai section of the Yangtze River; It conforms to two principles: the principle of fault liability; The principle of driving on the right.

If you do well, you can input the route into the radar in the form of nav line. When sailing, the driver can track and identify the position of the ship at any time.

2) Coastal Navigation: Procedure: General Catalogue of Nautical Books-Nautical Chart-Special Provisions

From the Yangtze estuary to Qinhuangdao, it spans the northern part of the East China Sea, the Yellow Sea, the Bohai Strait and the Bohai Sea. From the general catalogue of nautical books, you can find the nautical charts needed from the Yangtze River estuary to Qinhuangdao.

Process:

Step 1: turn to page 9 of the general catalogue and look up the partition index map. You can see that the selected chart is on page 23, page 2 1, page 19, page 17 and page 13.

Step 2: extract the charts needed on page 23, page 2 1, page 19 and page 17, namely 13 100,1217. 1 1700, 1 17 1 1, 1 17 12

Step 3: Formulate the principles of the route:

If you are familiar with the coastal waters of China, you can draw the route directly in the above picture.

If you are not familiar with the coastal waters of China, you can draw a sketch with the small-scale map 103 first, and then move to the navigation chart above.

This routing system is relatively simple, because there are several routing systems for reference, so it can't be wrong. From south to north, it is: Yangtze River estuary linear system, Chengshantou linear system and Laotieshan linear system. Connect the routing system with the shortest straight line, that is, the route from the Yangtze River estuary to Qinhuangdao.

Step 4: Special provisions: VTS reporting area. You can look at the VTS report regulations of each port first and mark them on the chart, so that you won't be negligent. From south to north: Wusong VTS, Chengshantou VTS, Laotieshan VTS, Qinhuangdao VTS.

Step 5: Set each WTP in the route, that is, the turning point, take the latitude and longitude, and input the GPS. Drivers can follow the route set by GPS.

Step 6: Use GPS to measure the distance between WTPs, calculate the total voyage and put it into the navigation plan. Calculate the flight time.

Step 7: Measure the distance of each segment and put it into the navigation plan.

Step 8: Route design should meet the requirements from berth to berth. Otherwise, the maritime inspection will fail.

The above is the actual flow of this voyage route. Of course, in principle, we should use the knowledge of geography and navigation, for example, the route design should sail in the water area with twice the draft of the ship (coastal navigation). To be economical, it is the shortest distance. The turning point should be set scientifically and parallel to the designated route as much as possible. You should consult the Route Guide, China Coastal Port Information and other related books.

Note: All nautical charts, nautical guides, light tables, general catalogue of nautical books and other books should be corrected to the latest edition.
