I did a search on your Naked guy, You got the title all wrong. The book is called "The Voyage of the Maiatla with the Naked Canadian" the Author is Andrew W. Gunson and the Publisher is Trafford Publishing in Victoria BC. Canada
I found him thru Travis Burke and Mystrey Tramp Records- Burke apparently wrote a song entitled the "Naked Canadian" which was inspired by the author of this book. who was cruising Baja at the time. I heard a clip of the song at Burke's web site and its sounds pretty cool.
I haven't read the book but the publisher has a outline online to read if anyone is interested, The book looks interesting but I think I will wait till its in the Library to read it. Its just been released so not surprising that you have't been able to find it yet.
hope this helps.
