    ToMeK Young naval architect

    Dear everyone,

    I am naval architect but very new in yacht design. For a hobby, lately I started working on some sailing yacht design. The problem that I came accross while working on bare hull form was how to evaluate the hull form in preliminary design stage.
    I am familiar what hull ratios are, but since new in sailing hull design I miss some frame values to use the as guide in hull design. Thus I would really apreciate it if someone could share with me some charts or numerical data on this problem. Ratios I would like to consider are standard hydrostatic ratios (Prismatic coeff. Cp, Block Coeff Cb, Max sect. area coeff., LCB%, LCF % ... V/Lwl ... )
    Hull is moreless modern (box design, with chines).

    Any kind of help or advise is very welcome.

    Thank you :)

    Along those lines, does anyone know of a sailing catamaran that, in terms of performance, planes more than it displaces?
