I would like somebody to define for me the phrase "maritime lien". I know what "lien" means in legal terms but what does it mean in maritime terms?

It recognises a recognition.

What does it recognise?

Recognition.

But a lien on the premises—

It gives effect to Article 20 of the Convention which recognises the salvor's right to hold possession of salvaged property until payment has been made which is known as salvor's maritime lien.

It would mean that people would have the right to hold the salvage.

It gives them the right or the recognition to keep it.
