It is indeed possible to find the intersections of two circles of position using only haversines. In enclosed file I show an example of finding one fix in one geometry. The interested reader may derive the needed formulas for other geometries and for both intersections. To be really useful I believe a form together with rules has to be developed. But this is work better suited for times when the northern archipelagos are locked by ice.
