    If you want the information handed to you on a platter, it's not there. But all the principals are the same for a 41' as for a dinghy. The loads calculations, modern materials use, appendages, rigging, weights, hull form, etc. But you certainly have to adapt what's presented to your situation. This is the way it's always been in the tiny specialized sectors of yacht design, with very few exceptions there are no widely available books on the subject. That's why we constantly search for papers and articles written by experts in the various fields, and why actual experience counts for so much and thus is carefully guarded by some. A great deal of what I know as a designer I learned by studying the drawings of other designers. I believe in sharing what we figure out, but there are limits as I still need something for the stewpot. A well known small boat designer recently told he would not publish any drawings for design review because someone would copy them.....It's hard for the beginner to learn much in that world...

    For a bit more information about performance dinghies take a look at National 12 designs https://www.national12.org/class/index.shtml and Banshee [UK-Cherub Class] http://www.uk-cherub.org/doku.php/designs/banshee . While I largely agree with the points in the previous post the world of small fast sailboats is a little different to the field of classical naval architecture as the immersed shape of the boat can be changed fairly significantly by sitting a few inches further forward or aft or altering the centreboard position.There is also a bit less need for exhaustive calculations to arrive at the strength of all components as you would find it quite hard to find a piece of 1X19 wire that wouldn't hold up a mast in a twelve footer,an approach that wouldn't be wise with a heavy displacement fifty footer for instance.It is extremely valuable to have a thorough understanding of how all boats work and you can extend your interest and knowledge at any time you choose.

    A great many modern racing yachts (up to 100' or so) have some form of movable appendage. And these same boats are constantly "stacking" sails on the windward side and shifting crew to change the centre of gravity, altering immersed shape a lot. It's often easy to pick out the differences in various boats, but if you look a bit deeper you find a lot of similarities (IMO).....:)

    One book that I hesitated to mention and which isn't strictly about design is this one https://www.amazon.co.uk/Aero-hydro...sailing science&qid=1570782853&s=books&sr=1-2 .The content is very thorough but the translator did a really poor job and the English version should have been checked by somebody with an understanding of the topic.Alarm bells went off when I read what the translator described the prismatic coefficient as defining.The original Italian text may be a lot less misleading.In spite of that,the diagrams of CFD plots for the hull and rig are interesting and there is a useful amount about the IACC boats the author worked on.

    best engineering/design book I ever read was for RC model airplanes. Made me feel like I was qualified to design my own full size aircraft. Just explained all the "voodoo" in nice simple terms with great explanation of the scary looking equations involved in aircraft design.

    Maybe a book for RC boat (power or sail) would be best place to start.

    Book about designing RC boat or aircraft doesn't need to hide and smother the good stuff under layers of hand-wringing about safety, durability, regulations, etc.

    SailDesign Old Phart! Stay upwind..

    Tad is (as ever) right, in that a modern performance dinghy design needs to be looked at with modern numbers and coefficients. Trying to design something like that using Skene's will lead to old-fashioned performance at best.
