Nautical Calculation Companion

A handy, splash-proof, on-the-water reference guide for every calculation needed for coastal and offshore navigation, plus all the frequently needed (but often forgotten) equations and formulae needed afloat. Each topic is followed by a worked example, and line drawings to illustrate the process. It is an aide-memoire, not a textbook. Explanations have been kept to a minimum and if you wish to see proofs then you must look elsewhere.
