    Hey everyone,
    I am looking for some information on the design and architecture of power catamarans. My plan is to design a catamaran between 7-12 meter length. I have read "Modern Ship Design" by Thomas C. Gilmer as well as VI&II of "Principles of Naval Architecture" by Rossel&Chapman. Both books have helpful information, but neither hits on catamarans. I understand there are different structural ideas when it comes to design a catamaran than a mono hull.

    I am looking more into the planing power cat vs displacement, but all information and suggested literature is much appreciated. I have also looked into some online courses, but haven't found anything that seems more informative than I could get on my own. If you disagree/have a suggestion through personal experience, I'd like to hear it.

    Thank you for your time.

    Are you designing it just for fun, or is this to build it? If you are planning on building, a stock plan will save you a huge amount of time and money.

    Skene's Elements of Yacht Design is an excellent book, and probably more relevant to you than Modern Ship design and PNA.

    How to Design a Boat is another very useful book -

    I have copies of both of the above books.

    Re powercat design, there is an awful lot of free info out there - for instance, have a look at all the free study plans that Richard Woods offers for his Skoota range of power cat designs.
    Sailing Catamarans - Click here for Power Catamarans (8 designs) http://sailingcatamarans.com/index.php/designs-2/6-powercats

    And do some googling re other power cat designers - the world is at your finger tips via your keyboard.

    In addition to all the above.

    There basic difference depends upon what YOU, as the designer wish to achieve with the design.
    Planing cats are "ostensibly" for those requirements of very high Fn....and by that I mean Fn exceed 2.
    Since displacement cats generally do the job just as well....so long as it is designed correctly.

    We published plenty of papers on power catamaran design: Our Research http://amdesign.co.th/Our_Reserch.html

    In particular, you can look at this: Nazarov A. Small Catamarans: Design Approaches and Case Studies//International Journal of Small Craft Technology, - The Transactions of Royal Institution of Naval Architects - Part B1 2015.
