    Have any document or suggestion about relation between machine power and weight of cargo for cargo ship (under 10000T). Could any one give me advice about it. Thanks in advanced.

    For a given Speed, Required Power is proportional to Gross Weight. i.e.

    To maintain a given speed, if Gross weight increases by 25%, H P must also increase by 25%

    Hope this helps,

    shouldn't there be more?
    A displacement hull, carrying a gross wt of ??? requires ??? HP, to achieve a speed of ??? Kts sustained.
    :confused: A formula to get a basic ratio between gross tonnage & HP, THEN the need to increase the load to HP ratio of 1:1?
    .
    For every ton, it takes ?? HP, to go ?? Kts.
