My father went to sea at fifteen.

She has three sons, who became sailors.

He saved a sailor.

He wanted to go to sea.

He became a sailor.

He went to sea when he was only 14.

A sailor is at sea much of the time.

All the skill of the sailors gave way to the violence of the storm.

As is usual with a sailor, he likes liquor very much.

He is thinking of going to sea.

A good sailor only requires a short time to get his sea legs.

My uncle went to sea at 18.

And he calls himself a sailor.

The captain went to sea when he was nineteen.

It's all the same to me whether you will go to sea or not.
