This is a comprehensive study-book for the RYA Day Skipper syllabus, and a practical guide to safe and enjoyable inshore cruising. The theory of navigation required for the exam is explained in detail and shown in practice, with worked examples and chart extracts. The syllabus also requires 15 days' sea-time, including 200 miles with eight hours' night-sailing, and this manual explains the skills of seamanship necessary to gain such practice competently and safely. A final chapter on pollution describes the effects on the environment of irresponsible boat-management, and suggests practical ways of protecting the sea from harmful waste and chemicals.
