For boat design, Greg Carlson's "Hulls" is worth every penny (it's free).
No, no. Sorry, Greg. It's a good program and it does the job within the
stated limitations. http://www.carlsondesign.com/#Fun_Shareware It is
limited to six chines, and it has no error messages -- when you screw up,
it
stops, but the interface is reasonable and the results are good. I used
it
to lay out the strakes for the Chebacco I'm building, but it took two
passes
because I needed seven chines for the six strakes. (The "wide sheer" pass
got the garboard strake and adjacents. The "wide garboard" got the sheer
strake and adjacents. The strakes in the middle matched to better than my
ability to cut plywood.)

Actually, I downloaded 1.89 and it looks like it will do more than 20
chines now. Also, it has a few other minor changes.

Now if only he would add in a flat-bottom option for the nesting
diagram.....

Newbie alert... I have only worked up very basic designs and built 2 boats.
Both were virtually visualized with the Carlson program. Both behave very
much like the program says it will (i.e. displacement calculations and
waterlines at a given load.) It is certainly worth every red cent spent.
(grin) Actually (and this surely defines me as a geek), the program is fun
to fiddle with doing things that I'll never build.
