The Unofficial Rules of Sailing
This is an almost pocket sized book of cartoons making fun of some of the mishaps of sailing - or at least those caused by not complying with the collision regulations. The line drawings are mostly of dinghies but the problems and mistakes remain the same.
The author is an American, resident in New York, so I am sure you can all guess what the cartoon covering Bearing off contains! If you struggle to remember all the Col Regs this book would provide an amusing way of revising and remembering them.
