Modifying Various Volumetric Parameters

10. Move the longitudinal centre of buoyancy (LCB) aft to 55% of the waterline length.

The waterlines are now fuller in the stern and sharper in the bow.

11. Reduce the prismatic coefficient (Cp) to 0.5.

The hull is now severely hollow in the bow and the stern sections are now flat at the bottom.

12. The forefoot parameter defines the radius of the bow just beneath the waterline. Reduce the radius to 0.1m to create a sharp corner.

The effect is quite localised affecting the shape of the centreline curve with minor effect on the waterlines.

13. Increase the prismatic coefficient to 0.57 to... 

...return the waterline shape to a much more appropriate shape for the hull.
