船舶狭水道航行须知

Narrow Channel navigation Instruction

1.总则

General Rule

1.1.狭水道是指相对水深或水道相对宽度较小的航道，狭水道内，航道狭窄弯曲，水浅滩

多，还有暗礁，沉船或渔栅等障碍物，水文气象条件多变，船舶交通密集，为了确保狭水道内航行安全，必须经常研究和掌握该水道的地理特点及水文气象条件，加强了望并谨慎驾驶，避免发生碰撞和触浅的事故。

Narrow channel means the waterway with small relative water depth or small relative breadth of channel. In narrow channel, waterway is narrow and curved, shallow, many shoal. There is redge, wreck, fishing stakes and other obstacle. Hydrometeors are changeable. Heavy traffic. To ensure safe navigation in narrow channel, should often research and know well the hydrometeors and geographical character and reinforce look out, steer prudently, avoid colliding and grounding.
