The author, Ralph Diaz, has for a number of years published a slim but tremendously valuable newletter for folding kayak enthusiasts, and this book is essentially the information collected by Ralph and his readers over the years, updated, corrected and expanded, together with new information collected for the book.
The result is a unique and absolutely invaluable reference volume for owners (and prospective owners) of folding kayaks. Ralph is no dillitante how-to author; he's a fanatic evangelical for folders, knows everyone in the business, and has helped countless people to select the kayak that's best for them. He also knows, and is know by, everyone in the folding kayak business.
Ralph takes you on a tour of the history of the folding kayak, the benifits and drawbacks of folders, a tour of the various manufacturers and models available from each, and walks you through basic kayak technique. He tells you about modifications that owners have made and tested, and where to get parts and repairs for out of production boats.
I have been enamored of folders since I saw my first one on Isle Royale back in 1968. As we talked, a young fellow not much older than I assembled a boat from two small suitcases that was far more seaworthy than the heavy aluminum canoes my compatriots and I were paddling. As a 14 year old I didn't have the wherewithall to buy one, and put the notion aside for a number of years. Last year, with Ralph's help, I found the folder of my dreams, a Folboat Greenland II.
If you're contemplating purchase of a non-whitewater kayak, you must read this book- even if you hadn't been contemplating a folding boat.
