I know you can buy them from Amazon but I'm cheap.
Plus I buy too many books to pay full price every time.
Boatbuilding - 1969, and Yacht Design and Panning - 1964, both from a local used book store for less than 20 bucks taxes included. I'm quite happy about it. I'm curious to know however, do later editions of both of these books contain any revisions or additional materials?
Now I just need to find a copy of American Small Sailing Craft.
I also picked up Thor Heyerdahl's The Ra Expeditions and an interesting little book called Oar & Sail by Kenneth Macrae Leighton. The later is an account of Dr Leighton and his voyage from Vancouver to Prince Rupert along BC's beautiful rain forest coast in a hand built Jollyboat.
