Nautical Calculation Companion

While traditional navigation has been largely superseded by GPS, traditional navigation remains a valuable skill, an enjoyable pastime and necessary for some navigation and training courses. This handy, splash-proof, on-the-water reference guide is an aide memoire of those calculations frequently needed (but often forgotten) for traditional coastal and offshore navigation and other equations and formulae which can be useful afloat. Each topic has worked examples, and there are frequent diagrams to illustrate the process. You may be surprised by the simplicity and elegance of some of the calculations included. The book finishes by listing the main conventions used in nautical calculations and providing conversion factors which may be useful on board. Even the most dedicated GPS navigator could find this little book handy to keep on board, just in case. They may even find themselves dipping into it when they don't actually need to.

About Fernhurst Books

Fernhurst Books was founded in 1979, initially publishing books related to dinghy racing. The list soon expanded to include cruising and other watersports. In 2006 the business was sold to John Wiley, but in 2013 a group of sailing enthusiasts (including the original founder) bought the list and name back, once again creating an independent nautical publisher owned and run by sailors. Fernhurst continues to publish books that instruct, inform and inspire those with a passion on, in or under the water. Their 140+ titles range from how-to guides to narrative to coffee-table books, covering sailing, surfing, canoeing, kayaking, stand up paddleboarding, swimming, diving and fishing.
