Re: Course to steer at a given speed.
sv+ jack- note the smiley at the end? Tongue in cheek response to the OP's question about a straight line solution to his question. I too have been getting where I'm going for 40 years. Here in the PNW it's not uncommon to be crabbing 40-50 degrees one way and then the other a few minutes later while trying to maintain a course.
