It is a fairly standard part of coastal navigation courses.
Your use of a bearing line will result in a curved course.
A example is crossing Georgia Strait from Vancouver to Silva Bay. On a strong ebb if you wish to minimize the time on course you will have to point further north than the bearing found on your chartplotter. If you simply use the bearing and maintain it you will up down by Thrasher Rock.
Of course, this is predicated on the ability to point.
