I have been working for 3 years, but I want to be a sailor. I have a bachelor's degree in electronics and have never been on a boat. What do I need to work on a boat?

I hope you can think it over. After all, you have jumped into a new field. I don't know if you can adapt to this new environment and survive well.

If you think about it, then:

There are many kinds of seamen, generally speaking, they are senior seamen (captain, Li Da, second mate, Zhang Zhang, chief engineer, bassoon, second engineer, third engineer and electrical engineer) and ordinary seamen (machinist, sailor, carpenter, mechanic foreman, boatswain, chef and squad leader). I don't know your foreign language level or your physical condition (no occupational contraindications such as color blindness, color weakness, infectious diseases, heart disease and hypertension). If you are all right, I suggest that you must be prepared to endure spending money for several months without any financial assistance. If all the above are all right, then my personal suggestions can still be learned. Because as far as I know, many large shipowners in the world have started to increase their shipbuilding orders. Personally, I think this may be the performance of the recovery of the shipping market (because after all, the shipping market has been in a downturn for five or six years, and it is time to pick up). Personally, I also think that if you want to get a high salary, you can learn from it in the long run, but it will take at least three years to learn from it (one year's study, a few months' delay in getting a certificate, internship)
