And there were many little sailboats on the river, tacking back and forth.

With the wind against them they will have to lose valuable time tacking back and forth.

Not three miles off the harbor mouth is a French ship tacking back and forth, and not entirely for pleasure.

They traveled unsteadily, too, tacking back and across the estuary, because the breeze was so light, and no longer astern.

And all through the night, tacking back and forth on the back track, he shook out canvas as fast as the wind would permit.
