Re: Multiple hard chine sailing yacht modeling

[Marven]

Optimising your chine profile to reduce the resistance can only be done by calculating the drag. The Delft yacht series included in Delftship is not suited for that since it calculates resistance based upon hydrostatic values and coefficients. What you’ll need is a way to calculating the resistance directly from the geometry. This can only be done by using CFD software.

The answer to your second question is yes. If you have selected 3 or more points then you can use the “Align” command from the “Point” menu which is found under “Edit” in the main menu. It will project all points on to the line which is defined by the first and last selected control point.
