Freedom of the seas is a term used to describe a principle in international maritime law, which grants ships the unrestricted right to navigate and trade on the high seas. However, there are various synonyms that can be used in place of freedom of the seas. These include the right of free passage, the principle of open seas, liberty of the oceans, and unrestrained navigation. These terms all connote the same idea: that ships can navigate the open seas without fear of obstruction or limitations imposed by coastal states. The concept of freedom of the seas is essential for maintaining a healthy and prosperous global economy, as it allows for the efficient movement of goods and people across the world's oceans.
