I enjoyed reading this book mainly because Bruce Kirby explains how he started designing and how the thing grew up. I found this alone is worth the price.On the other side the first edition of the book was published about 35 years ago, and most of the articles and the pictures seem to be left unchanged. I'd say almost the same about sailor's interviews.It would be a good book with an another title: the Complete History of Laser Sailing.If you're looking a way to improve your sailing technique, choose something else:RYA Laser HandbookorThe Laser Campaign Manual
