Could be. Once or twice I've seen on a Bolger plan a notation
something like "PCB after SA".
Howard
something like "PCB after SA".

Which PCB then hand drafts. For instance, the
panels for Col. H.G. Hassler appear to be CAD
developed. [I am only guessing.]
Perhaps also some of the step sharpie fillets.
You are right on the button Howard.
But Bolger on CAD may be a bit premature. He hasn't mastered email yet!

That was the theory when I first started writing programs in 1959. One of
these days it will be fulfilled.

A hand-drawn, hand-lettered plan is a work of art in its own right.
It's hard to have the same feeling for the output of a CAD system.
CAD would have aided PCB in producing complex shapes in sheet
plywood. He has been limited pretty much to using a few simple
cylinders and cones, whereas CAD frees the designer to work with many
cylinders and cones on the one sheet of ply. Michalak says pretty
much the same thing in fewer words.
Bolger has described his technique for producing his range of bilge-
panel ply designs (e.g. Diablo):
-- draw the side and bottom to the exact shape
-- have them cut out and assembled over a few bulkheads
-- place a sheet of ply over the gap between side and bottom on one
side then mark and cut it to shape.
-- reproduce the shape of the bilge panel on the plan.
Using CAD would obviate all this. A look at the Selway Fisher website
will show numerous examples of ply designs that have benefited from
the use of CAD.

Using CAD would obviate all this. A look at the Selway Fisher website
will show numerous examples of ply designs that have benefited from
the use of CAD.

Computers are there to help, not control. They are most useful for just this..

Just read Jim Michalak's bi-monthly online newsletter and in an
interesting essay on his design process, he throws in a nice Bolger
anecdote:
exception (determining the shapes of twisted and bent panels) I think
no computer gear is required. In fact that gear might get in the way
and slow you down. And you might find yourself designing projects that
are limited by the capabilities of your gear. An inexpensive hand
calculator is almost always sufficient. Drafting tools can be minimal.
A three foot by four foot sheet of 1/2" plywood is a good drawing
board although you will have to surface it with a layer of heavy paper
to negate its grain. I met Phil Bolger about 20 years ago when he was
still working in his ancestral house. He was quite famous and seeing
his drawing room was quite a treat. At that time he had a full sized
sheet of plywood atop a stack of concrete blocks and could make very
large drawings on it for some of the very large boats he was drawing.
There was no computer gear and he had no intention of getting any
although he said the salesmen were hounding him a bit. Ten years later
he had moved into his boat home and his drawing board was quite small,
maybe 2 foot square at the most. Perhaps he had a larger board on
shore somewhere. At any rate I'm sure he is back on shore now in a
real office complete with big drawing boards and electronics. He still
does his drawings by hand and I'm sure most of you know that he has a
true artist's hand and for him to use a cad program to put out final
drawings would be a crime.
"would be a crime."
