Help understanding software

I've downloaded a couple of the free programs. Carene 2002 and Carlsons Hull Design. I'm naking some of the darndest geo-shapes. but nothing that resembles a boat hull.
X, Y, Z? windows that change their own numbers? obscure abreveiations. NO step 1,2,3. I didn't think I would turn out a world class hull today, but I did think SOME sort of tutorial would be included. OR somewhere on the net I could go.
What I have now is the "Give a monkey a typewriter and a million years...." theory. Any advice? I just wanted a 28' scow hull for a canal type river boat. Plus the learning something new feeling. Gotta go, it's time for Bonzo to make some pretty shapes.

 

step 1,2,3

1) Go get yourself an evaluation copy of Rhino www.rhino3d.com - you get 25 saves to evaluate it so be careful!

2) have a look here http://boatdesign.net/forums/showthread.php?s=&threadid=1401

3) post results in gallery for us to have a look at!

Watch out for Rhino ... its adictive!
