Unfortunately, he appears to have followed such a style for this book. The paragraphs are too long and the wording unnecessarily complicated. It is simply hard to read. I could be wrong, but I get the impression that Mr Yapor's words were spoken into a dictating machine and transcribed by a typist rather than written down by the author. The sections on diving techniques, practices and equipment say nothing that can't be found in BSAC or PADI manuals.
Boat safety is approached largely from an American boat operator's point of view.
There is plenty about liability releases, insurance and boat equipment mandated by US regulations, but these are not the same as UK regulations. If you want to know about boat safety, read the relevant BSAC and RYA manuals. I simply laughed at the sections on crew. If you really want to know about slick American customer relations, read a book from one of many self-styled retail business gurus. Some divers might find worthwhile information in this book, but there is nothing here that cannot be found elsewhere in more readable and worthwhile texts.
