Book excerpt: A full-scale reference book for everyone boarding a seafaring vessel. The information is accessible, concise, up-to-date, and potentially life-saving. This is a weapon against ignorance at sea, and a no-brainer buy for all those who are interested in the safety of their passengers, their boats and themselves. The book covers everything from emergency radio operation, proper employment of safety equipment, to survival and first aid in the water. It also includes a full glossary and index. It was originally published in the UK this year by the Royal Yachting Association (RYA).
