    Hi all you guys,

    Let me first introduce myself, at the moment I am a student, I am studying Naval Architecture and Marine Technologies. Since I've started in this sector of knowledge I I've been attracted to yachts, cats and sailyachts in particular. Now I have only a bunch of exams to take to graduate...but I realize that not everything can be learned at the university. So now I am enthusiastic over designing my first yacht. I am searching the net for some time now, to find any statistic data on about some ratioes like displacement/DW or LBP/Cb but nothing so far...today I found this amazing forum (I want to congratulate you it is really great) and wonder if anyone can help me with my problem.

    P.S.
    thank you in advance

    Hi Archivo and welcome to YF.
    If it's not already on your bookshelf, pick up a copy of Beebe's "Voyaging Under Power" for a classic read on your new profession.
    BTW, the 3rd Edition is by James F. Leishman (of Nordhavn fame).

    Thank you very much Loren I will definitely look for it. But aren't there any statistics I can see online?

    Do a search for Dick Boon of Vripack, he published many of his design philosophies and some of the hard data that you are looking for.

    This may get me into trouble, but what the heck. Look at the old sailing ships with miles of rigging and acres of sail, tall and loaded with gun and balast and know that many of the designers of these ships never spent one day in school. Get yourself to sea . Feel it roll beneath your feet. There are too many people designing boats and yachts today who should be designing apartment buildings.

    Maybe that's why there are so few of them around anymore... :D


    And by the way NYCAP- in another thread you were talking about rebuilding carbs... aren't those something you're supposed to count in your diet?:p

    You have shown your age today CAP ;)

    Ah yes Ken, you got me. LOL. But remember Y2K and the scramble to find old programmers because their work was the foundation for all the newer stuff. Just think, in a few years it will be litium crystals (beam me up Scotty) and you'll be reminicing about the grand old days of electronic ignition and (now what was that stuff) oh yeah, gasoline & diesel I think it was called. :D

    :) The first thing that popped into my mind when I read that is the Vasa, a beautiful ship that I visited in a museum in Stockholm. It matches the description perfectly, and it sunk after the first few minutes of sailing.

    Sorry, couldn't help it.

    Archivo, there's not much statistics on form coefficients to be found on the web. Just like you won't find the recipe of Coca-cola...

    You can find a lot of useful information on boatdesign.net on the "Principles of Naval Architecture".

    Thank you guys, now it's all up to me, I guess. It is a pity that people doesn't share knowledge but I guess it's just the way it is...
