Well written, with wonderfully informative illustrations.
Pay close attention to the title because that is exactly what this book is for.
Precisely directed at those who are restoring an old canoe or putting a sail on an old canoe, and desire with that sailing apparatus, to maintain the patina and character of the "oldness."
If you are, as I am, seeking simply to put a sail on a modern canoe, I suppose there is still a good deal to learn from this book. I am getting inspiration from the diagrams and may one day, when I get more free time, build something like what is in this book.
It would be silly to build something according to the plans in this book and put it on a modern canoe. It would sail, no doubt. But the great sin would be the mixture of old and new.
There is enough technical information and close up drawings that I can work from and adapt to using aluminum and modern, manufactured items to create something to get on the water faster than building it all myself from scratch. That is mainly what the thrust of this book is all about, building and sailing it yourself, whilst keeping it's antique patina.
Great book. The author knows his subject.
Also an attractive coffee table book, even if you never do anything with the knowledge therein.
