Actually, 3 miles might be a bit short. Excuse the tech analysis but if one assumes you sail 0.5 miles from the rhumb line between the upwind and downwind marks and the arbitrary waypoint is only 3 miles away, then 0.5/3 is 0.1667 the sine of which equates to an angle of about 9.5 degrees. That would mean about a 10 degree error in your course.
Conversely, 10 miles would be 0.5/10 or .05. That equates to about 3 degrees error. Dang, my brain hurts. -- Dennis C.
