This Douglas style ASA plotter has scales just right for sailboats going at an average of 5 kts. A days work will be covered on a standard sheet of paper. I did a custom drill hole at the center and at the zero of the edge scale to facilitate DR and celestial plotting. Quite satisfied with this model :) Cost is about $15.
I very much like the reciprocal course angles included on the perimeter degree scale.
