    I am looking for some help. I do not have a background in
    hydrodynamics or naval architecture.

    I have a need to calculate the potential forces my 32' boat will
    excert against a floating dock in various sea conditions. My goal is
    to determine if the (float/piling) structure is sufficient to handle
    the size of my boat. I have determined the range of expected wave
    amplitudes / periods for my location. I am in the process of working
    out the pile lateral load capacity and deflection at the ground
    surface, as well as the float attachment strength.

    The key piece of information that I need is the force potential of my
    boat in various sea states. I want to assume worst case, which I
    understand would be the sway of the hull resulting from waves in the
    direction abeam of the the boat. If I can determine the boat's
    acceleration caused by waves in the direction towards the float, then
    I can determine the potential force applied to the dock.

    I would like to know, do any of you know where I can get access to
    software that can provide this information with the entry of the
    characteristics of my boat (LWL, draft, keel profile, displacement..
    etc)? I know this software exists, but what I have found is
    expensive. I am not designing ships, I just need it to solve my
    problem. Is there any free or nearly free software out there that can
    do this for me?

    Thank you,

    Dean
