Look at the software section of www.boat-links.com.
It's all hull design software. Noting on construction planning.
You might want to look at project managment software for construction.
I put a small MS Project example on my website under
www.ncf.ca/~ag384/Boats.htm .

On the subject of using software to modify interior design, first you'd
have to take and enter all the measurements of the exsisting interior?
Unless it is being stripped down to bare hull for which hull measurements
would suffice?
