Basics of "starting system?"

I thought that I'd ask a general CNC "starting out" question. My questions
are imbedded in the objectives. Thanks in advance to any/all that reply.

Objective: Be able to produce a CNC generated object. (Eg. small model boat
hull, 60" in length). I'd like to be able to "build the object" on CAD
software (what type is best?) from a hard copy of 3 view plans. Then I wish
to have the ability to take this CAD image (what type is best to generate?
.dxf?) and "load it into CNC" file (What software is best to accomplish
this?) and cut a small boat hull out of foam. I anticipate using a hotwire
setup for this. Are there machines or plans for machines that I can obtain
to build such a device? I've seen similar CNC foam cutters for aircraft
wings...but I don't see how they would work for a boat hull with strakes and
ridges. What is the best type of computer platform to accomplish all of
this? Should I use Solidworks? DesignCAD?

Anyway, that's the gist of what I'm trying to accomplish. Any guidance would
be appreciated. Thanks - John
