Jeff H....I need a little of your knowledge.
I also have Practical Sailor''s "Practical Boat Buying" - a two volume set from 1999. While I can''t attest to the accuracy of the reviews I find it very useful to get someone''s opinion of a particular boat and its history, and entertaining as I do my own boat research. Hardly a couple of days go by that I don''t refer to it. It is also highly recommended by Chuck Gustafson who has a book "How to Buy the Best Sailboat" that I also like.
Another reference is Mauch''s Sailboat Guide. I have no personal experience with it other than to look at its web site - www.mauchs.com - where you can check out a sample page and the table of contents. It consists of three supplemental volumes that can be purchases individually. I think it is more into specifications than reviews.
Hope this is helpful.
