So to summarise, roughly what lat & long are these waypoints, how far apart are they, and if they are a long way apart, which heading source are you intending to steer by?
When sailing a GC route we made very little use of waypoints. At each fix or updated EP a new initial course to our destination was calculated using azimuth (ABC) or sight reduction tables and course altered accordingly, using a normal gyro compass. None of this at very high latitudes and always at ship speeds. Small scale gnomonic charts were useful for a visual appreciation of the location of the vertices.
