'Course' in the Bible

We put out to sea from Troas and sailed a straight course to Samothrace, the next day to Neapolis,

After we tore ourselves away from them, we put out to sea, and sailing a straight course, we came to Cos, on the next day to Rhodes, and from there to Patara.

Of course, I myself was convinced that it was necessary to do many things hostile to the name of Jesus the Nazarene.
