Modifying the Length of the Hull

40. Increase the length of the hull to 120m by changing the Lbp parameter in the attributes panel.

The length parameter performs a geometric scale on all of the other parameters and the hull will become larger in every dimension.

The hydrostatics of the hull will increase accordingly (although draught that the hydrostatics have been calculated at has not been increased accordingly in this example).

41. Zoom all to show the whole hull form.

42. The number of section contours need to be increased to allow for the extension in the hull. Return to the Contours Setup dialog (Tools -> Contours...), press Generate and then Press OK.

The missing contours are now filled in.
