Shipping companies are mainly divided into two categories:
1, own a boat, rent it to different companies, and earn money by chartering. Such companies are generally large. Have your own boat. The way to rent a boat is also to rent a boat by boat, that is, just give it to you. Or support leasing, including renting seafarers together.
Supporting leasing is mainly divided into voyage chartering (running a line) and time chartering (such as half a year). There are many voyage charters among the supporting charters. There are many time leases in bareboat charter. As I am an English major, the translation of some terms may be a little different, but the meaning is correct.
There are also some shipping companies that rely on their own chartered ships to undertake business. They usually rent out the boat and then equip the sailors. Run some popular routes. At the same time, the integrated ship is divided into small pieces and leased to others. Such a shipping company has a certain intermediary nature. They can be divided into many parts according to the number of intermediary businesses they participate in.
