A more thorough explanation:

Definition: Towing service refers to the assistance provided to a vessel to expedite its voyage, not necessarily in response to dangerous circumstances. It is different from salvage service, which involves rescuing a vessel in need of help due to present or potential danger.

Example: A boat owner hires a towing service to transport their boat from one marina to another. The towing service will attach the boat to their vessel and tow it to the desired location.

Explanation: In this example, the towing service is being used to expedite the boat owner's voyage from one marina to another. There is no present or potential danger to the vessel, and the towing service is not providing rescue or salvage assistance.
