Necropost, I know...
but my "Dirty" method of intercept is simple: start by matching course with the target. turn (toward the bearing rate) so that bearing rate of the target is reduced to zero. apart from certain exceptions, you are now on an intercept course
With practice you will be able to make educated guesses as to how much to turn with trial and error. I usually do it in 10 degree chunks but you can just set the rudder and ease back when you get close also
