Loss Prevention. Towards Effective Navigation/Предотвращение потерь. На пути к эффективной навигации

Книга на английском языке
The Shipowners’ Club provides P&I insurance for small and specialised vessels and, as such, the majority of our vessels trade in coastal waters. The art of navigation is second nature to deep-sea mariners but it can be something of a mystery to those crews who do not need to use this particular skill very often.
Our Condition Survey Programme often highlights the fact that crews have a limited understanding of the rudiments of basic navigation and we also see claims arising where poor navigation is a main contributing factor. A better understanding of the subject will hopefully go some way in reducing the incidence of those claims.
The purpose of this booklet is to open the window on navigation in a very basic way. It is primarily aimed at those mariners who are not fully trained in the art of navigation.
This booklet is one of three publications in a series and it is envisaged that together they will help eliminate some of the difficulties that befall those not so well versed in marine navigation.
We remain forever indebted to Captain H. Subramaniam for compiling this booklet series for us. Captain Subramaniam was a distinguished member of the nautical fraternity in a career spanning over 6 decades, including over 30 years of teaching experience. Apart from this series, he also authored eight textbooks on the operation of merchant ships which continue to be used by seafarers across the globe. It was his ability to put a subject across in a nutshell that made all his books easy to understand and helpful to those these are intended for.
