THE ART
OF WOODEN BOAT BUILDING
draft jan 24-07
april-4-07 Faring the Charlotte
. More Boat , Less Dust
This glimpse into wooden
boat building at Gannon & Benjamin, from the perspective of an interested
observer, artist, and cultural anthropologist, may be an enlightening sidebar
to the technical notes on faring: "more boat, less dust."
For me, art and wooden
boats are inexorably linked, I am an artist, it cant be helped. I use
imagination is a tool. The first thing I drew as a child was boats. Among
my earliest memories is being on the foredeck of my uncles dragon, and
I learned to sail before I can remember. Im a wooden sailboat nut, and
that cant be helped either. Ive also been doing woodwork forever.
Sailing into Vineyard
Haven on my friends wooden ketch, and hanging out on a mooring for a
while, felt like coming home.
If I returned in the fall,
there was an opportunity to show some paintings,
to try to make myself
useful at G&B, and my friend agreed to lend me his boat
to live on for the winter.
Charlotte is a 50 foot
wooden schooner, a form of self expression that the yacht designer, Nat Benjamin
is building, to sail with his family and friends.
Soon after I began faring
the hull of the "Charlotte," I asked Nat if there was a book or
article he could recommend on the subject. I was surprised when he said that
I should be writing it. I had been reporting back to him with my discoveries
and the methods that seemed to be working, as they came up. Nat seemed amused.
As we went off in different directions in search of lunch one day he said,
"I'll see you back at the campus"
When Nat referred to the
shop as "the campus," Plato, and my days as artist in residence
at the great books school came to mind. Sharing ones discoveries
is part of my definition of art.
When an educational institution
allows ideas and questions to be discussed from multiple perspectives, without
the customary, strict divisions between disciplines, surprising discoveries
and solutions can result. Its something akin to "cross pollination."
The more I compared making art to wooden boat building, the more they seemed
to have in common.
Form and Function
Although it was not a
marine architect who coined the phrase,
"form follows function,"
the remark is seldom more clearly
expressed in any of man's
endeavors
than it is in the hull
of a sailing vessel.
Training the Senses
In a classical art education,
we study sculpture and drawing to learn to see more articulately, to see the
object as if we are holding it in our hands.
Having binocular vision
allows us to triangulate as our eyes dart about the space around
us, from one point of focus to the next.
Sculpture: the articulation
of mass and space.
Drawing: the two dimensional
illusion of mass and space.
Seeing like Touching
It wasn't until Benjamin
had made a number of half models, had taken lines from the models and had
built the hulls, that he was able to truly see the form that a lines
drawing represented. From that point on, when he made drawings he was
drawing mass in space ... seeing, like touching.
Because Nat's mother was
a sculptor, this process may have been instilled or, to some degree been instinctive.
In any case, Benjamin has a refreshing regard for art and how it's interwoven
with man's other pursuits.
Nat pointed out that it
was the blind brother who was handed the half models for final approval in
the Herrshoff brothers design team.
Alternating between the
vantage points of art and the boatyard provides rich possibilities for comparison.
Having pursued some understanding
of art for many years, I have a growing list of ideas about what art is and
why it is be of value. I call the list, another vain attempt at defining
art, in part because art expands to include each new addition
When this list of ideas
is applied to the designing and building of wooden boats the similarities
become apparent.
On Making Art
The capacity that
I have access to
is only mine to share.
there is pleasure
in making art
paying homage
to those who have
gone before.
"As humans we are
curious, we push at boundaries, we explore the world around us
and we explore the world
within.
There are pleasures,
delights and surprises along the many paths of learning...."
As an artist,
painting is both my vehicle
of exploration
and the record of my discoveries.
Once the initial fairing
was done and the first paint was applied to the Charlotte I went out looking
for a studio.
feb-07
I have a small studio....
there's no heat of course,
but with the glass on
the south side, if the sun's out it warms up in the afternoon Once I got rolling,
there were about forty new paintings underway. I'm not a linear thinker.
Exploring a number of
tangents simultaneously is part of my nature. It seems make sense to me to
work on a number of different paintings at the same time.
After a while, the whole
lot seemed to evolve into some kind of unified, multidimensional collage.
Im doing most of
the painting outside. Working in the wind, snow and sunlight
brings some of the urgency
of plein air painting to the work. Being able to see what Im doing from
a distance helps. Knowing what a painting will look like at a distance, as
it is being made, is part of what makes a painting engaging. Think
of the impressionist paintings that dissolve into brush strokes as you approach.
Seeing the whole from a distance, while working on one particular spot, may
be a skill that applies equally to painting as it does to seeing a hull fair
in ones minds eye. Visualize is the current word for it.
It relates to, looking ahead so you dont trip over your feet.
This assemblage came along
early and seems to be part of the backbone of the collage.
There is a section of
hull from a 30 foot Malabar that was cut up at the boatyard. I pulled 6 pieces
from the dumpster as potential art material, and subsequently used this one
to take a spiling lesson. When I started painting, the two squares were among
the first beginnings. These two have survived, whereas most of
the other early beginnings have been finished and
repainted a number of times. When I came to the Vineyard in the summer, there
had been a boat in at G&B for some re-planking. The turquoise bottom paint
with new mahogany planks and stripes of the bright orange was a colour combination
that Id never seen before in nature or in art. I set out
to work with that combination. As it happened, the unfortunate Malabar had
red bottom paint, a black boot-stripe and white topsides. The two small square
paintings were begun side by side. Brushing the cadmium orange oil paint onto
the absorbent, unprimed masonite left prominent brush strokes. This texture
was revealed a little later on when I dragged the white paint stick across
it. Presuming this was just a beginning, I took a tube of thalo turquoise
to scratch some lines across the thing so all the lines werent going
in the same direction. The other square got a splash of turquoise and white,
a few drops of accidental orange and the two were set aside as good beginnings.
Artistic gravity
drew the three elements together.
Wondering how this piece
of old boat was going to evolve, I
propped some paintings
in front of it to see if it wanted to be painted. Thats
how it came together.
It seems to tell the tail of faring the Charlotte. Without intention, the
orange brush-strokes with white became planking. The lines running across,
an echo of the weeks of diagonal planning....The new shutter plank, a curiosity,
a division?. The turquoise painting attached in the upper half, seems to be
something of wind and sail and wave. However one chooses to describe such
method: intuitive, subconscious, or accidental? the assemblages,
the element of surprise, of discovery, is all part of its attraction for me.
It captures surprising elements of my experience and surroundings and lays
them out for interpretation.
Living Traditions : a
distinction
There seems to be something
distinctive about what is going on at G&B.
Theres a rich history
of traditional boat building. There is innovative boat building.
Gannon and Benjamin seem
to have found a combination that works. Moving the tradition forward, by breaking
with tradition.
Angelique 48 x 66 in.
oil
Looking at one of my new
paintings, a spontaneous painting in a limited range of colors, Nat said it
seemed tropical and used the word, "tension" to describe what he
liked about it. He connected his use of the word tension to yacht
design. A friend of Nats had used the word "tension" to describe
the quality that best designs had in common. After some discussion it became
apparent that Nat was not using the word "tension" as it is commonly
used in talking about art. It was not the suggestion of movement, of force
and resistance. Nor was it the tension between
a flat surface and the
illusion of space... The wood in wooden boats, like the wood in acoustic stringed
instruments, is persuaded into a shape and held in tension.
.That wasnt it either.
This was one of those
rare and valuable moments for me to be able to see my work from anothers,
visually articulate perspective.
Whether we are looking
at a work of art or an inspired hull, there is something that sustains our
gaze. Something about exactly how this example departs from the "usual,"
and engages our imagination.
Something of the necessity
to explore, can be detected.
Curiosity, Intention and
Integrity
Perhaps we can recognize:
curiosity, intention and integrity in the work of others, if we ourselves
go about the world with our eyes open.
Open to exploring
whats beyond a resounding achievement?
Open to, what
if, the best example to date was altered
pulled a little further
in a particular direction?
Stretching the boundaries
may be the kind of tension that Nat was referring to.
The Inspired Compromise
in Arts and Science.
Nat Benjamin uses the
word compromise to describe the balancing act that ultimately
produces a hull shape.
Theres a tension
between the various attributes of a hull that pull the design, first one way,
then another.
Stability, speed and pointing
ability are the kind of attributes in the balance.
Its primarily experience
and observation that informs this balancing act, but there must be some "art
" to this "science."
Coming up with just the
right reconciliation, given the infinite number of variables involved, make
this an "inspired" compromise.
Inspiration may first
come to light
as the half model takes
shape
displacing the fluid touch
of the carver's hand.
Sight Sound and Feel
Sailing is a feast for
the senses. After sailing a number of boats in a variety of conditions this
sensory input will become increasingly valuable as it is cross-referenced.
Much of this knowledge will be filed under the heading "feel." When
this "hands on" experience is added to the theoretical information
gleaned from other sources, it enhances the value of the reference.
In designing, building,
and sailing wooden vessels, the connections to other fields are limitless.
Applying the knowledge gained in what seems to be completely unrelated fields
can reveal surprising solutions. Although the dolphin and gull are obvious
references in the realm of wind and wave, the knowledge of glaciers and drumlins
for example, may also help inform faring a hull, and the shaping of a ballast
keel. In that regard, there is "art" in the breakthrough
when the solution comes out of the blue. Necessity being the mother
of invention, the hands becomes waves as the experienced sailor picks up a
half model to evaluate how that hull will feel in a seaway.
Approaching a Task
Having been given the
task of faring the Charlotte, a benchmark Benjamin of yacht design, having
neither held, let alone carved a half model. I would need to draw on other
experience.
Sculptors speak of seeing
the form contained in the shape of the block, and releasing it.
In this case all the information
is in the basic shape of the planked hull. Imagination being one of the tools
of art, I needed to become the water flowing across the surface of the hull.
From my first day with the wooden gouge planes working in the hollow transition
from the keel to the broad flats aft, my hands were guided by imagining the
water flowing diagonally across the planking. As the wave, I was supporting,
the wide flat stern without undue pressure or disturbance. I knew that there
would be a harmony between the hull and the wave under the stern. By then
the layer of water at the interface would be moving at nearly hull speed.
I had learned about the turbulent and laminar flow of water as a student of
geomorphology. Woodworking, plastering and reconstructing rusty old trucks
were among the skills I had developed working as an artist.
Having used a wide variety
of both hand and power tools, in a wide variety applications, enabled me to
improvise. Im afflicted with perfectionism, so theres something
appropriate about making art or wooden boats.
The artists eye
is also a tool that can connect natural observation, with applied science
The Big Picture
Being able to see from
a distance while working on the particular, is a skill developed in art that
finds a new application in fairing a hull.
Faring the Charlotte;
More Boat, Less Dust.
In the process of faring
a carvel hull, a series of flat planes are transformed into a single smooth
shape. When I arrived at G&B around the beginning of November, Nat handed
me an assortment of wooden, straight-soled gouge planes and something that
looked like a leg-hold trap with a handle on it. He pointed me at the Angelique
in the hollow sections aft and said something to the effect of, see
what you can do with these.
The process of faring
normally involves planning diagonally across the planking.
Diagonal planning allows
you to maintain the smooth flow of the planking, fore and aft, while transforming
the series of facets into a smooth curve across the planking. On the round
sections amidships, diagonal planning effectively increases the diameter of
the arc to something closer to the arc of the planking fore and aft. The plane,
besides not working so well across the grain doesnt plane
unless some portion of sole is in contact. Its the length that gives
it control
otherwise youd have a spoke shave, so bigger arcs are
easer to work with. Obviously the plane wont work in tight hollows,
but its surprising where you can get into, working at an angle, just
slightly off the run of the planks.
Charlottes keel
and lower planking are of Angelique which a dense tropical hardwood. It will
cut with very sharp hand tools but a good deal of force and momentum required
to push a gouge plane through it . Because of the interlocking grain,
it checks in a surprisingly explosive way.
planning diagonally across
the inside curves of the dead-rise or the outside curves farther up in the
turn of the bilge, the plank edges are vulnerable. Where the grain reversed
in the Angelique, from one plank to the next, the plank edges were getting
shredded. I presume these traditional tools worked with the wood traditionally
used for planking such as Teak, Mahogany and Cedar.
However, Necessity
again, it was time to try a different approach. About that time Nat came by
to see what I was up to. He approved, handed me a power plane and said, see
what you can do with this. There was some discussion of
grinding some gouge shaped
blades, and not concentrating on a particular section. As we made our way
forward Nat pointed out what wood needed to be removed and described the shapes
he wanted in the transition from keel to garboard. There were some cubic feet
of wood to be removed from the garboard alone. I was beginning to understand
the magnitude of the task at hand. Initially, Nats idea was to use the
power plane only on the Angelique, the rest of the planking up to the shear
plank is Silver Bali, which apparently sands beautifully. The
shear plank itself and bulwarks are Angelique.
Staging set-up: Long section
facilitate flow.
Imagine you are holding
the full sized vessel in you hands. One hand
holding the vessel the
other becomes the sea it displaces. As you draw the sea passed the hull, the
transitions from the slight hollow sections of the bow into the full round
sections amidships will become apparent. Knowing the shape of the hull is
essential. Knowing where the transition lines from hollow through flat to
round shapes are is part of the big picture that should be understood before
tooling begins.
Set up the staging starting
from the ground to follow a shape along the hull. It helps with the flow,
and it helps keep track of where youve been. Once you have the power
plane set up with a grind and depth set up-for a certain hull shape, take
it as far, fore and aft as it works.
Plank thickness
Another objective in fairing,
is to arrive at a faIr hull, having removed as little
of the plank thickness
as possible.
Keeping track of the thickness
is possible because, in a given section of planking the thickness will have
to come down thinnest piece of plank stock in that particular section. This
holds, whether hollowing or rounding. You can keep track of a few small areas
in the centers of round sections and on the edges of hollow sections of planking
that remain the original plank thickness.
As luck would have it,
my shop is without a jointer, so I am quite familiar with the power plane.
I am accustomed to using a power plane to take the shape out of boards before
they go through the thickness planer or table saw. I also cut my teeth
climbing around pole barns with a heavy, worm-drive skilsaw.
Warning
You will
be using the power plane to do the opposite to what it was meant to do in
all manner of awkward and dangerous contortions.
remember the thing
will rip your fingers off faster than you can blink. That being said, Nat
was sufficiently impressed by the method the results that he thought I should
write it down, to share
. which comes back to one of my definitions
of art
Different tool, Different
approach.
Approaching thirty foot,
clear, tropical hardwood planking with a tool that can take out a huge bite
in an instant requires a plan
some careful trial and observation
trial and error not being
an option.
Observation#1
The plank edges are not
flush.
The planking needs to
start out in different thicknesses depending what section of the hull its
intended for. The garboard, because of its width, needed to start out about
double the intended thickness so it could be backed out to the
shape
of the floors on the inside.
Whether on inside or outside curves, the planks that require more shaping
on both sides need to start out thicker. As a result, not all the plank edges
come out flush.
It seemed to make sense
to start with a section of proud planking in order to work out
the procedure, shaping a plank with a small margin of safety. Starting with
the hollow sections, having installed curved blades I began to plane down
the center of the plank. This particular section of plank needed to end up
hollowed-out and the whole surface needed to come down to the level of the
adjacent planks. . Once the edges of the proud plank became flush with the
adjacent planks, the hollowing could begin on the adjacent planks.
Touch
Developing a more articulate
sense of touch will be helpful.
If you close your eyes
and draw your hand, palm first across a series of planks you will be able
to see what needs to be done. The task is to transform those broad
facets into a smooth curve. As the work progresses, and the facets become
smaller, you will soon be able to feel what needs to be done more clearly
than you can see it.
A Tool to See Transition:
As you move fore and aft,
use a short straight edge at right angles across
2 or 3 planks as a visual
aid. It will let you know whether or not you are still in a hollow section,
and how hollow that part of the plank needs to be. Remember that the transition
from hollow to flat is gradual and that it changes from plank to plank as
you move along. Moving fore and aft the length of a staging plank, following
the shape that the tool is set up for seemed to work
Observation#2
With the first pass down
the center of a plank, it was clear that the planking wasnt as fair,
fore and aft as it first appeared. The good news is that it would become more
fare in the process. The process being; several passes down the center, then
over lapping passes, working towards the edges to produce a series of slightly
hollow facets. The final, very light pass, being down the center of the seam.
There will be some diagonal planning to follow so having the plank edges,
ever-so-slightly lower, will afford them a little protection.
Observation#3
Drawing ones hand
across a section of planking, hollowed out in this manner indicated that the
faring was nearly there before any diagonal work had been done
and the plank edges were completely intact.
Tool Set-up
Rounding the front corners
of the base the power plane a little with some sand-paper will prevent them
from digging in.
A chip guide will be needed
because you will be working over your head in a shower of chips some of the
time, otherwise you will be getting it in the face. I used a paper cup and
duct tape,
Power Rabbet
There were places where
the keel met the garboard and where the planking forward met the stem that
called for a rabbet plane. Angelique being Angelique, I thought that a set
of straight blades, shoved over to one side and put in on a bit of an angle
might be worth a try. It worked.
The Diagonal Planing Process
As you move up from the
tight turn of the tuck into the deadrise another set of blades with less curve
will be needed. Keep 2 sets going. Keep them sharp -
twice a day for Angelique.
Theres a delicate
balance between too little and too much depth of cut. Too little and the blades
pound on the shoulder rather than the cutting edge.
Adjust the staging plank
so you can inch along comfortably as you work across 4 or 5 planks.
Adjust the plane to take
only the high spots.
Broad, shallow over-lapping
strokes is the aim.
The power plane transfers
information through your hands.
Rocking back and forth,
inching along you will soon be able to tell when its fair
and when the plane is
tipping over the slightest ridge. Because the previous work was fore and aft,
there will be ridges. If the ridge is obvious
check it with your hand
take it down with a few fore and aft strokes and then proceed.
Magical Moments
Planing downward, diagonally
from right to left, inching along from right to left.
I was holding the plane
on an angle, turned clockwise about 15 degrees so the blade was leading with
the planes following edge. ( this is were a drawing will help) With
slightly more weight given to the BACK hand and the following edge of the
plane, the plane was riding the fair curve of the previous stroke and moving
it forward.
It was exactly the same
feel, motion and result as using a hand plane. The results were both amazing
and gratifying. When things were working this well, the results were not just
fare but shining. Sanding would only be required to take the shine off
to give it some tooth to hold the paint.
Surprising Results
With Angelique and Silver
Bali, the power plane could be set to remove a finer shaving and achieve better
results than using any of the hand planes that I tried.
In places, it looked as
if the faring had been done with a cabinet scraper.
Of course the power plane
needed to be very sharp and set right, and you needed to be in a position
where you could bear down on it.
Trying to use a hand plane
on ribbon-grain and rising grain sections of the Silver Bali that would produce
lifts and tear-out no matter which way they were planed.
It was a relief to see
these precariously explosive planks fare and intact without having to resort
to the torture board.
As the hull gets closer
to fare, a new tool is introduced
Tool : The Torture Board
Perhaps from the French
a
thin board for removing pies from an oven or
A piece of flexible piece
of quarter inch plywood about 3 feet long and 8 inches wide with two blocks
for handles on one side, and 40 grit on the other. I took it for a test drive.
It was clearly a fool-proof method of removing the remaining high spots to
produce smooth curves and a fare hull
. But with a lot of wood to remove
and some of it very hard, I thought there must be a better way.
Because the torture board
describes a fare curve as its either pushed into a hollow or wrapped
around a curve, it occurred to me that something similar might be used to
simply mark the high spots.
Tool: The Chalk Board
I scuffed up the surface
of a flexible 4 inch wide piece of quarter inch plywood-about 4 feet long,
added handles to the other side, added chalk, et voila.
By working it back and
forth diagonally, all the high spots were revealed.
A uniform pattern indicated
fare. The chalky ridges with adjacent unmarked bits indicated work to do
.
with either the power plane or with a hand plane. The German, wood bodied
plane with the horn shaped handle worked nicely because it was easy to push
or pull. The hand plane was a nice break from the noise but you had to be
on a section of the hull where the planking would allow using a hand plane,
and where the staging allowed you to lean into it.
Fare didnt necessarily
mean shiny.
After the introduction
of the chalk board, I was relieved to be able to see just how fare things
were. Knowing that the shine wasnt necessary and there would be sanding
eventually, and that Bali sands beautifully, the method evolved.
The Chattermark Method
When the power plane is
not held down with sufficient pressure to get a clean cut, it produces closely
spaced chop marks rather than a smooth surface.
The surface can be either
flat, or a fair curve without being especially smooth. Work in the broad full
sections of the hull, where the fore and aft planing had been done, could
proceed using the chatter mark method. The power plane is easier to use and
more predictable than the hand plane here because of the wider throat. Where
the sole of the hand plane would be in contact with the curve in virtually
a single line at the blade, the wider throat opening of the powerplane provides
two lines of contact. With the curve of the hull protruding into the cutting
zone, the necessity of reducing the depth of cut becomes clear. The plane
is held lightly against the hull and can remain in contact on both backward
and forward stroke. With the plane set for a minimum cut, work in long, overlapping
parallel arcs. Move back and forth along the staging plank using the opposite
diagonal in each direction. When the chalk board reveals a uniform pattern
of very fine diamond shapes, its ready for sanding. Because the hull
is fair and only
needs to be sanded smooth,
a minimal amount of sanding and dust will be necessary.
Diagonal planning Angelique
in the hollows of the tuck is difficult with the power plane but its
much less difficult than using any of the other tools that came to hand.
The Square Pad
.
a motorized Torture Board
The next step in the tool
department would be the 8 inch grinder with 40 grit on a inch square! of quarter
inch ply glued to a flexible pad. This unlikely sounding assemblage has the
benefit of not digging in on the edge because the cutting power diminishes
with surface area towards the tips of the plywood. It takes some getting used
to, not being able to see the outside edge of your effective cutting circle
- you have to be careful not to bump into things. It is heavy,
powerful and a brutal
thing to try to control using 40 grit on the underside of a curved surface.
I gave it a try. I had marked a high spot with a magic marker on the keel.
I started it up and leaned on it. After a few seconds I stopped to see just
how fast this brute ate wood. The magic marker was still there. I went back
to the power plane. Besides being; lighter, easier to control, it doesnt
produce such a choking cloud of dust.
Observation#4
.Angelique
laughs at 40 grit
Resume working with the
power plane. There were hollows that were too tight to get into because of
the width of the plane base but if one was curious and if one had a spare
power plane, aluminum grinds quite easily.
The benefit of using hand
tools is having
a break from the noise.
The 4 inch Grinder with
a metal buffing wheel can be useful in the tight hollows to smooth out the
work of the gouge planes. Push it along like a plane, with the back end pushed
down, so you are cutting with the following half of the disc
.or a flexible
40 grit disc might also be worth a try.
When you come across a
new inspired solution, that works out beautifully,
to some structural problem.
It being an expression of your nature, inclinations,
curiosities?
How is that different
than sharing some time at Lucy Vincent beach in a painting?
Does this definition of
art fit boat building?
Art is: Having as much
fun as possible doing what you love to do and making a record to share.
