A friend of mine asked me to draw up a 1 meter R/C sailboat hull to his hand sketches so he could have drawings of bulkheads and eliminate the trial and error assembly process to build everything fair. This was drawing in Solidworks. Every parameter on this hull can be driven from equations...the amount of chine, the angle of the chine, the elevation of the chine, the amount and placement of rocker, the width of the top, etc, etc. All or none can be interdependent. I assume no responsibity for the design - I was doing what I was told!
