I wrote a visual basic program to design my hull.
It allows far more numeric control of the hull form.
The hull is defined from the rocker line, the chine height and width, the bottom panel width and turn of bilge as a percentage of the chine width, the topside angle, the gunwale height and the wing angle.
Each of these is defined at the bow, the transom and a blend of first second and occasionally third order curves.
The whole hull form is defined by a matrix of numbers.
The program will then work out how the hull floats for a given displacement position and heel angle. It will then work out hydrostatics.
It can scan heel and LCB to allow hydrostatics to be plotted over a range of values.
This allows me to very quickly adjust the hull form to get the desired hydrostatics, and grantees that the hull form is inherently fair.
The program displays line drawings but not rendered 3D.
It will generate panel shapes to make the mould frames and planks and for the foam planks.
These are generated as text files that can be dropped straight into the command line of autocad.
It would also generate full station sections that could e imported as sketches into Inventor to loft and view a rendered 3d view. This was a more convoluted process, but it is useful to view in 3D before starting to build.
