Whether you are manning the wheel or setting the autopilot, it''s as easy (or difficult) to read between the compass graduations as on them; however, normal steering errors, estimating currents and leeway, etc., will add up to a much larger tolerance than even several degrees. In the middle of the ocean, that is not important. As you approach its jagged edges, however, you need to rely on your GPS, radar, and piloting skills. I won''t give away my age by suggesting celestial navigation as being helpful.
