Answer Details
The vessels that operate on specific routes on high seas and oceans are called "Liners". These ships are designed to transport cargo and passengers on fixed routes, and their schedules are usually published in advance.
Passenger liners are ships that transport people from one place to another, while cargo liners are ships that transport goods and products. Coastal liners operate along the coastlines and may stop at various ports along the way, while ocean liners travel across the open ocean.
Tramp liners, on the other hand, do not operate on fixed routes, and their schedules and destinations may vary depending on the cargo they are transporting and where it needs to go. Tramp liners may carry anything from raw materials to finished goods and may travel to various ports around the world.
Therefore, the vessels that operate on specific routes on high seas and oceans are a combination of passenger liners and cargo liners.
