Generally speaking, the navigation field of vision must be above 5.0, because it is related to the safety of ship navigation. The requirements for marine engines are lower, which is 4.8 at a glance. Another number seems to be 4.6. You can find that the engine is more difficult than sailing, and it is more difficult to get the first mate's license, that is, the third mate (learning to sail) or the three-tube boat (learning to sail). The employment rate of navigation and marine engineering is almost 65,438+000%, and I can guarantee a monthly salary of about RMB10,000. ! Do you say high? After the promotion, the salary will increase. The captain's annual salary will be more than 400 thousand yuan. After learning to sail, it will be cleaner to work on the ship. Learning to work in the engine room and dealing with oil engines will be dirty and noisy. But when you are on duty, the centralized control room will have air conditioning. If you have any questions, please contact me. I am a marine engineer.
