Diagram of the Relation between the Total Weight,
Speed and Horse Power of the boat
The below diagram is normative and not binding in any way as many different circumstances
influence the result, especially the type and shape of the boat, the propeller and its placing as
well as the horse power of the engine.
Seek the scheme to the right of the intersection between the actual length in the waterline of the
ship and the total weight.
Draw a straight line between this point (the intersection) and the fixed point in the bottom left corner.
Where the line of the desired speed crosses the straight line, you can read the required horse
power vertically below.
If you know three of the specifications, you can by means of these schemes find the fourth one.
