    Thats a bit few information.

    Would you mind to give us some more data, i.e. displacement, loa, etc.

    Regards

    @apex1
    Sorry bro for that less information.Actually i am a student of naval architecture of 3rd year & i dont understand power calculation,propultion system & rudder design that much & i was actually looking for the method how to determine those things.if u can help me in that case i will be greatful
    to u.
    i have attached my hydrostatic calculation & maxsurf drawing for ur better understanding.

    Select energy you intend to use.
    Only oil or others ?
    Do you have a budget for the others, like biogaze, solar panels, wind mill ?
    Will you use air buoyancy to lift hull and reduce friction under hill ?
    see Brian H. post about it

    Are you going to give sound advice now, you "expert" ???:D

    Biogas on a boat, yeah? cool...:cool:

    Do you have 1500 pax on your floating litter bin?

    Or any other Yacht?

    What are you searching here?
    Did the bad guys pee in your sandbox?
    No other playground in your suburb?

    Have you evaluated your needs in energy for light, heating, equipment

    Can this equipment be class A grade like diode for light, PMBL motors instead of exited asynchronous...

    Kistinie, Would you let this student work his way through the basic propulsion needs before you start piling all this crap up to his ears?

    Diodes are nice, give a lot of light for the weight and energy needed but he is not to that point in this discussion yet.

    Diodes was to explain the spirit of my answer
    Question was MOTOR
    My answer was in motor, magnet or not ?
    Between 2x more energy needed


    If you do not dream of improving the world you will have to live in, when your 20...
    When will you do it ?


    Do you think a 2010 student must learn how to install a Cat at tail, a generator at bottom, and lesson is over ?



    What does mean "non pulcherrimum et non felicem locum" ?
    My Latin is highly corroded
