Description: Piloting and shiphandling is about individual judgements bused on knowledge allied to practical experience.
Paul Williamson’s book is a real addition to the pool of knowledge on the subject. The text is easy to read, often delivered in anecdotal style and, for experienced pilots will often ring bells as it draws to mind half forgotten night watches and sticky manoeuvres.
There may be issues or techniques we would query but then wo all know that there are often several ‘right’ ways to do a job, Aspiring pilots will gain great advantage and first class advice from the content and Paul’s approach allying practice and theory.
In short, at last we have a text which, in written form docs what pilots will always do whenever they are gathered together socially - ‘swing ships’.
It is a must for every pilot station and will find a welcome place on any pilots’ bookshelf.
