Creating a YachtLINES hull surface

The following example illustrates the process of creating a YachtLINES hull surface which is normally generated immediately. The example then goes on to show how changing the parameters effects the shape of the surface produced by the algorithm. The commands and operations used to generated Yachtlines surface are shown in more detail in the help.

The YachtLINES hull surface produced in this example can be downloaded here: yachtlines.geo

The YachtLINES surface is initially displayed showing only the construction geometry.

Turn on the interactive update to have the hull surface update after every parameter change.

Display the hull contours to show the hull surface shape in more detail.

Increasing the maximum beam, from 3.25 to 4.0.

Increating the waterline beam (Bwl), from 3.17 to 3.5.

Increase the transom beam, from 2.0 to 3.0.

Now controlling the hydrostatic parameters, changing the LCB to 50% shifts the waterlines forward.

Changing the LCB to 55% shifts the waterlines aft.

Increasing the Cp to 0.6 make the waterline much fuller.

The hull surface can be converted to a BSpline surface to allow the control points of the surface to be manipulated directly.
