Nautical Calculation Companion - Practical Companions
Alastair Buchan
A handy, splash-proof, on-the-water reference guide of those calculations frequently needed (but often forgotten) for traditional coastal and offshore navigation and other equations, formulae and conversion factors which can be useful afloat. Each topic has worked examples, and there are frequent diagrams to illustrate the process.
