I tried to buy a used one last year for $250.00 but after I placed my order, I was told it wasn’t available.
The board in fig. 29 with the 2 trailing fins looks similar to a drawing my dad made back in the late 60’s early 70’s. My brother sent it to Brewer or Noll and never heard a thing.
Checked out from a great library near my house–it’s apparently out of print again–checked Cornell Maritime Press website
Naval Architecture of Planing Hulls byDr. Lindsay Lord, Naval Architect/Marine Engineer, was and remains the essential text on the design and performance of planing hulls. He was a working naval architect, designed quite a few successful boats.
There’s no meaningful discussion of surfcraft design that can’t benefit from a look at this and I’d think of it as a prerequisite. At least, if you want to get past the ‘Duude, it’s bitchin’ radical, duuude’ level.
The older ( from the 1946 edition on ) editions are fine and reccommended if you can’t lay hands on the 1963 edition. Alibris has three right now. In the same way that the surfboard community is squirreling away Skil model 100 planers, we oughtta be acquiring copies of this.
The Old Man gave me his copy of Lord’s book, then made me study it. Had things gone a bit differently, I’d be a practicing NA right now, instead of a beat-up old fisherman. But… the both of us wanted to go to sea when we were of the age to go to university, and we did.
I got my copy (hardcover, 1963 edition, in excellent condition) about 6 months ago off the internet for $60. So they are out there to be found.
I’ll scan some of the pages to take some of the work load off of you, if you plan on making a PDF.
I also have a good book called “Shape and Flow: The Fluid Dynamics of Drag”, by Ascher H. Shapiro. Which is a good foundation for understanding for how fluid acts, and how fins work.
I found the ‘shape and flow’ book at a rented house in Torquay during a Vic teams titles once. Had some good info in it, but it’s old too.
I think the scientific understanding of things has progressed a little since then.
But that all depends on what you are designing I guess.
It’s not that old. 50 years. The book is not very complex, it just explains and demonstrates how bodies act and react in fluid flow. I don’t think that the basic theories and observations have changed much, or at all. Maybe the more complex theories and formulas, that are not in this book, have been modified in the past 50 years, but I don’t think there has been a paradigm shift in the scientific framework in this field, that would deem this information outdated.
Is there something specific in the book that you found incorrect, or did you discount it simply because it is old?
If it is the latter I would suggest reading “The Structure of Scientific Revolutions” by Thomas Kuhn, where you can learn about how “the scientific understanding of things” progresses and doesn’t progress. It is a must read for anyone who is interested in science, the history, the future, and the role of science.
PDF’d everything but the stuff about ballasts and bulkheads and anchors and propellers this evening. 4 chapters of said very boat-specific stuff omitted outright, but the Addenda, Index, Table of Contents, Preface, Introduction are all in my bunch–it’s all I need + .
OBP and Doc–you guys are welcome to copies of the PDFs–etmo is posting them up somewhere and will post the link–but you guys can PM me and I’ll email you.
