'Course' in the Bible

So putting out to sea from Troas, we sailed a straight course to Samothrace, and on the following [day] to Neapolis,

And it happened that after we tore ourselves away from them, we put out to sea, [and] running a straight course we came to Cos and on the next [day] to Rhodes, and from there to Patara.

And slipping the anchors, they left [them] in the sea, at the same time loosening the ropes of the steering oars. And hoisting the foresail to the [wind] that was blowing, they held course for the beach.
