Relation between machine power and cargo weight

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.
