I'd start at http://www.boat-links.com/boatlink.html "The Mother of all
Boat Links,"
and pass via http://www.boat-links.com/linklists/...tml#bdsoftware
to get to Greg Carlson's http://www.carlsondesign.com/#Fun_Shareware where
his hull design program is.

The download includes quite a few sample designs; digital files which, if I
remember correctly, can be or are in Auto-CAD format.

Can anybody point me to free downloadable hull lines plans? I don't want
to
build a boat I am experimenting with a 3d modeller and wanted to try
modelling a boat. I would prefer if the plans are in cad format but that
isn't essential. I would prefer monohull sailboats 20' - 40' but would
look
at anything.
