If you are planning to make a shipmodel or just generally interested in shiphull design, try this site:
www.defcar.comUnder the program/software download link, you can download a free (trial) version of the Shipgen hull design and construction program from defcar (actuall in use by various shipyards).
Even thoug saving and printing (exporting) have been disabled, i still get quit some fun out of it.
Just zoom in, capture the screen and print
Have fun
