I'll try to finish this section up before the first of the
new year.
New Hull Designs
I like to work with models. Some people use software (like Rhino
or AutoCad) but I don't like 3D design software. I worked as a 3D programmer
for almost 7 years (writing OpenInventor and OpenGL C++ code for
visualizing confocal microscope data) and I just don't like it.
You can make scale models, working with a scale like 1/8" equals 1'
Cut tentative side and bottom slabs from gray cardboard or formica.
Glue it together with a hot melt glue gun. Do this a dozen times,
as needed, until the model starts to look right.
Full Size Design Models
Or you can work full size. That's what I do. I start with an idea about
side panel length and height, approximate side flare and width at the widest point.
I cut the sides (but NOT the bottom) and then fasten them, with drywall
screws, to a stem and to a temporary chipboard transom. Then I cut out a
chipboard trapezoid that has the side flare and width I want.
I put that in on a layout mark (I usually work on 2' centers from
one end.....but layout marks are arbitrary).
Then I add a few more trapezoids here and there until I get the
shape I want. If you feel compelled to put temporary trapezoid formers at
a given location (on a layout mark) then you have to keep re-sizing
temporary ribs in order to adjust dimensions. It's easier to forget about
layout marks and just move a temporary rib forward or back, as needed, to
tweak the shape. You have to iteratively jiggle dimensions until you get
two things: the overall shape you want, plus a smootly-arching
chine and gunwale. Then you trace out the bottom, button it up
and there you have it....a new boat.
How do you know what shape you want? You have to start off with a fuzzy
idea and work with it. Look at boat photos. Use a tape measure and a clipboard
to roughly document factory boats you like. Buy Roger Fletcher's Driftboat book.
Spend several weeks or even months working with a full size model.
Spend a lot of time ten steps back, staring at the shape of your boat model.
Fiddle with it. Change it. Go away for a week.
One day you'll look at it and you'll know you've got it.
