What is another word for press of sail?
Pronunciation: [pɹˈɛs ɒv sˈe͡ɪl] (IPA) 
Press of sail is a term used in sailing to refer to the maximum amount of sail that a ship can carry. When a ship is going against the wind, it needs to have a certain amount of force in its sails to move forward. Synonyms for press of sail include full sail, all sail set, maximum sail, and full canvas. These terms are often used interchangeably and are indicative of a ship's ability to travel at its top speed in the prevailing winds. In contrast, terms like reduced sail, shortened sail, or reefed sail are used to refer to when a ship reduces its sail area due to strong winds or rough seas.
