I bought this book and used it to build an ultralight solo Kevlar canoe that I'm very happy with. The construction process was fun, and it's certainly more satisfying to make your own Kevlar boat than to pay $2000 for a new one. An added benefit of building your own is that you'll have complete confidence -- and the necessary materials -- when you need to repair it. This book is not an absolutely complete, step-by-step guide; however. You will have to use your ingenuity from time to time and read between the lines. I definitely recommend it if you want to build with Kevlar; indeed, it's the only book of its kind. But you should read it three times before you start building, and discuss its method with your resin/fabric supplier, who may give you valuable supplemental information. And, ideally, talk to someone who has already built a canoe using these methods. And search the web for discounted second-quality Kevlar fabric, which is perfectly good for boat building!
