Re: How I build a Free!ship boat from scratch
Chris and Robert
I've been playing with a 3D CAD program called "Cheeta" that runs in OSX. I haven't yet
figured out how effective it might be but it does have an unwrap feature and though not
free it is only $100 -a long way from what most 3D CAD programs run -especially
TouchCAD (the premiere Mac boat design package with unwrapping) at almost $1000!

Thanks for the info Bruce. I'll be filing this one away for future
reference. I had asked a week or so about this vary subject, and
you suggested the FS group (which I joined). To be able to print
output, I (re-learned) that I will need a real CAD package to print
the output. Now I just need to find a (free) CAD program for the OSX.

As some people have asked...
Here is how I build a simple Free!ship boat from scratch.
(download program here:)http://sourceforge.net/projects/freeship/
Start the program.
Ctrl-N, for File|New
A properties dialog box pops up. In it:
Choose three longitudinal points...and two vertical points.
...length, beam, draft as you want them, I prefer Imperial units over metric.
(Most Bolger boats, due to his elegant and spare design nature, can be
modeled with just three longitudinal points. For some more complex
hulls, you will need four longitudinal points. Very rarely do you
need five. )
This creates, essentially a single shearline strake, or what should be
viewed as the topside/gunnel line edge of the boat. I drag this into
shape establishing overall shape and size, the sheer line, in profile
view and plan view the way I want it. Leaving for the moment a big
hole for the bottom of the boat.
Using the Edge|Extrude command, then I select the bottom edge of this
strake and add new strakes, working down towards the keel. Drag these
to shape, and repeat if the hull is more complex than a Bolger Teal.
The difference between a curvy edge and a hard chine edge involves the
Edge|Crease menu command.
Add the transom by selecting points and using Face|New command and Edge|Crease.
Ctrl-A means 'select all' and [Esc] means de-select all.
That's it for the basics.
Explore the all menu commands to learn all the features.
For modeling of existing boat designs, using 'Background Image' tools
are helpful, and that is accessed using the right-click menu.
To work with expanded panels (and hydrostatics), you need to master
the 'Layer' menu and especially the Ctrl-L layer properties dialog
box.
Also, here is a collection of Free!Ship bookmarks including tutorials.
