Re: Course to steer at a given speed.
Sailing isn't straight line, or constant speed. Your course will vary based on wind direction, speed through the water, etc so while your question is a good mental exercise it's not a practical application for sailing. In other words, line up the bearing line on your chartplotter with your destination and do your best to get there as soon as possible:-))
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.
