Man, ain't that the truth. You got to SIMPLIFY.
But I don't understand, if you can build a model, why
can't you draw it?
I tend to take an existing design, and change it.
This works out a lot of the basic stuff, like ergonomics
and scantlings easily and then it can be tweaked to adapt
to whatever.

Everyone learns from everyone else
who succeeds in putting their work out there.

I approach boat design through the drawings of others.
If one wants to build something that is as close to the
designer's idea, a drawing works well in looking at all of
the details.
Often, after studying drawings of a boat, I am surprised
when I see the boat actually in the water.
Not that the boat is any different then what I know the drawing
says it should be, but there is something else that comes through
that is not in the drawing.
Some people say boats are alive. I'd say some are more alive than others.
Some people approach design instinctively. They visualize a
design, then try to build it.
Others try to choose a set of parameters and then design
a structure to deal with it.
There is a linear path that either approach takes.
They vary depending on where the designer wants to go.
When I taught myself to draw boats full size (loft), I realised
how much easier it was to then build the boat.
The drawing gave me a ready made pattern for every piece in the boat.

Mabey it could be looked at this way.
In order to communicate your idea to somebody else, you have a number of
choices. Let's call them your Media choices.
So far you have used the written word to communicate your idea.
Other Media choices might be photographs of the boat model.
Drawing would be another.
Video might be another.

I notice that people who sell boat designs usually use drawings.
That doesn't mean they have to.
I can imagine selling a design for a kit that has no drawings at all.
For instance, you display photos of your design...the actual boat.
People download a bunch of files..binary code and save it to a floppy.
They bring the disk to their local "guy with a computer driven router"
He cuts the design for the guy and the guy assembles it based on a
sequence of written instructions telling him how and in what order.
The advantages of this method are obvious. No paper..shipping...etc.
The disadvantages are that there might not be a "guy with a computer
driven router" willing to do it.
But another hidden disadvantage is that many people are used to drawings
and won't like paying for a "computer file".

So, why do you even want to "get it down on paper"?
Is it to sell the design?
You mentioned that you don't plan on building it.
Who will build it?


Well if you think it is an idear to ask a 3D router the cost of a
small impire, 4 engineers the cost of a farm and using a foam block
the price of a Volkswagon to produce a 20 feet boat , you are wrong.
Atleast for 20 years you have had the oppotunity to router 3D, then
why do you think it shuld be an idear to make a plug in foam when
after that, you need to sand and fill, then do that form that will
make your one boat ; do you realise what this will cost ?
You suggest foto's ----- what is a foto other than a "drawing" added
perspective, but without measures and showing no sections no water
lines no data for the router; how would you even translate data-less
graphic into router data accurate down one hundred of a millimeter.
The only N.C. technikes that acturly offer a way to make this work is
2D cutting of sheet material.
What you don't realise is, that the lofting you learned is what modern
CAD work ontop of. That the CAD program already "know" lofting as that
is what the CAD program build ontop of. --------- That's why a lot of
the part result of a Loft process is not there to se, in a CAD program
; the program alrady worked further than that, it already used the
offset tables , the collum and row measurements to acturly put the
frame on the screen ; how do you othervise think a rib could be there,
if the CAD program isn't already acturly by graphic showing the bloody
stoneage tools in a much more effective and accurate way, ---------
beside when you messed that much with tradisional boat drawings, why
havn't you realised as anyone else, that the old methods show the
foults when you realy build.
Have you even realised why CAD is better to show a spline, ----- have
you ever tried to change the front or aft of a vessel on a tradisional
set of planes in 3 projections , and then tried the same with a CAD
system, as _then_ you will know.

Do it, ------ make the experience as how others had to build boat
after boat, develobing the technikes and skills, ---- test it and show
the result.
Still if you just realise that they project planes and go to Mars
based on 3D CAD , you will also realise that with a true 3D drawing
you do not need any model , unless you also question they ever reached
the moon , as you _can not_ produce a 3D drawing , unless everything
work in real.

You suggest spending a million producing a small boat from some
foto's, but don't realise that for new technology to be new, it must
be new and different.
Beside develobed by somone with just a bit experienc and the ability a
lot participant in this group hate, the ability to develob new, true
new.
