摘　　要：船舶在海上航行,为避免船舶搁浅,应保持足够的富余水深。航海实践中,驾驶团队通常将海图上读取的水深数据换算成实际水深或龙骨下水深,结合测深仪测出的水深数据,来判断航行水域的水深是否充足与安全。海图水深数据的准确性取决于水深数据的测量与标注。正确读取和理解海图水深数据,是船舶驾驶人员的基本技能。通过分析海图水深数据在航海实践中的具体应用和使用海图水深数据的注意事项,帮助船舶驾驶人员正确评估及合理使用海图水深数据,确保船舶航行安全。Vessels shall maintain sufficient under-keel clearance to avoid grounding during navigation at sea.In practice,the navigation team usually converts the depth data read from the nautical chart into the actual depth or the depth under the keel and combines the depth data from the echo sounder to judge whether the depth of navigation waters is sufficient and safe.The accuracy of nautical chart depth data depends on the measurement and annotation of depth data.Reading and understanding the depth data on nautical chart correctly is a basic skill for vessel navigators.By analyzing the application of nautical chart depth data in navigation practice and the points for attention in the use of chart depth data,it aims to help vessel navigators correctly evaluate and reasonably use chart depth data to ensure the safety of vessel navigation.
