I am very proud and happy to own one of these books. This is definitely not an experience that normally you would be able to get without paying a fortune. I have all the famous sailboats' plans in my room. Yes, may be not much to read but you can find documents to read everywhere however it is not easy to find original Olin Stephens plans...

Contrary to what the other reviewer says, this is a great book, in larger format, with images of the drawings on nice, heavy paper. Absolutely a must-own volume for S&S fans and friends. If you want to read more on Olin himself, buy "All this and Sailing, Too". If you want to see a lot of beautiful boat drawings from, arguably, the most successful yacht design firm in the 20th century, buy this book.

Lines: A Half-Century of Yacht Designs by Sparkman & Stephens, 1930-1980, consists almost entirely of scaled down photographic reproductions of actual Sparkman & Stephens company drawings. Several are faint and barely legible. The few pages of text about Olin Stephens are uninformative and read like promos for a music cd.
