Description:
David Burch's book is a comprehensive review of emergency navigation at sea that is a pleasure to read. Throughout the book he keeps returning to first principles of navigation which he expounds with admirable clarity. His emergency procedures are explained in terms of natural ( often astronomical ) laws, so that their rationale is fully comprehensible and their practical applications and limitations clearly defined.The book is a far cry from some emergency handbooks, with their mixed bag of semi-anecdotal advice, and is no intended to serve as such. Yet in an emergency situation, with the sextant overboardand the watch broken, it would be of far more use to the unfortunate mariner.
