I currently have charge of a 68’ traditional motor vessel. I have in hand, a copy of Inman’s Nautical Tables, 1947 version, first published in 1821. My copy contains a reviser’s preface which describes a revision made by Rev Hall, in 1910. This revision note, also contained in my copy, gives the all-haversine formulae for solving spherical triangles, and layout and examples of their use.
