（船）启航，出海
(of a ship) to leave a port and start a journey
The boats will put (out) to sea on this evening's high tide. 船将在今晚涨潮时启航。
I'm always struck by the sight of a great ship putting out to sea.
These huge yachts rarely actually put out to sea.
There were almost twenty vessels waiting to put out to sea.
The ship needed major repairs before putting to sea again.
