A more thorough explanation:

Definition: A salvor is a person who saves a vessel and its cargo from danger or loss. They are entitled to salvage. A salvor is also known as a salvager.

According to Martin J. Norris, "A salvor is a person, who, without any particular relation to a ship or property in distress, performs useful service, and gives it as a volunteer without any pre-existing contract that connected him with the duty of employing himself for the preservation of the ship or property."

For example, if a ship is sinking and a person jumps in to help save the crew and cargo, that person is a salvor. They are not necessarily connected to the ship or its cargo, but they are providing a useful service to save it from danger or loss.

Another example could be a person who finds a lost ship and helps bring it back to shore. They are not obligated to do so, but they are providing a valuable service and are entitled to salvage.
