、。
Because of the storm, the ship couldn't set sail.
Literal
Storm [because-of-に-ために], ship [topic-は] depart-port-could-not.
出航 ('set sail / depart port') is the nautical counterpart to 離陸 (takeoff) for ships — a formal compound that a casual speaker would rarely use. Note the optional comma (、) after のために, which is a stylistic choice to break the long adverbial clause from the main clause.
