: Does anyone know of any software that can be used to design kayaks with hard
: chines. I would like to design my : own Yost style just for fun.

I use New Wave Systems "Pro-Surf". It can be used to design single and
multiple chine hull sections as well as Rounded hull sections.

A less expensive version called "Pro-Chine" is for chines only designs.
Otherwise it has all the features of "Pro-Surf".

Attached is a pic of a Pro-Surf screen open to 4 windows.

A full set of documentation is provided with the software. They used to
provide a free trial download version with full capability but limited to 25
saves. I don't know if the trial version is still available. Check at the
Link below.
