    It has become widespread practice in recent years
    to copy a house brick as the hull form,
    point the front end
    then stack 3 greenhouses on top,
    and a playschool
    a football terrace on the back end
    this is all coated with 30 tons of the ugliest plastic,
    a barbicanfull of brutally modern glass
    6 tons of filler
    a warehouse of tacky boring,dull carpet
    68 tons of tacky brutal stainless steel

    if you follow these guidelines
    you cant go wrong

    Peter's answer is all too correct, but as I assume that you want a more factual response, I will have a stab at it. It would be useful to know what lies behind the question however;

    what is your starting point? (ie what do you already know?)

    why do you want the information? (if you are about to design a motor yacht, you will need much more info than you will get here.)

    You ask about "ratios" do you mean design FACTORS?

    Length will depend on desired use and accomodation.

    Breadth is typically close to length/3.

    Draft depends on hull form and intended displacement. A V-bottom boat will have greater required draft (all else being equal) than a flat bottom.

    After that, I would need to know more of the reasons as described above. Finally, my own area of experience is sailing dinghies, pulling boats and small motor boats. I merely quote above some rules common to all of these. You may also be better posting on the Motor Boat Forum.

    Basic dimensions for yacht design are such that:

    Rig Dimensions = I, J, P, E, etc.

    Boat Dimensions = LOA, LWL, B, Disp, etc.

    Size of Sails = LP, Area
