Week 35: May 1-7
"Plan the work and
work the plan."
All good projects
have a plan. Boats can have many plans, depending
on how large and complex they are. The "lines
drawings" or simply "the lines" show the shape of the
boat; construction plans show the shape and position of
the timbers making up the boat. In addition, there
may also be cabin plans, sail plans, and system
(electrical, engine, etc.) plans.
The picture to the
right shows the construction plans for ISABELLA.
At the very top of the picture (click on the picture to
enlarge) are 3 cross-sectional views at three different
stations (i.e. frames) of the boat. Think of them
as putting the boat through a gigantic bread slicer:
each slice shows the outside shape of the hull at that
point along its length.
In the middle of
the picture is a view of the boat as seen from above.
One half shows the deck; the other half illustrates the
construction just underneath the deck.
The side view at
the bottom of the plans shows the profile of the boat,
including its stem, stern, keel, framing, and deck
structures.
The scale of the
drawing is also included (in this case, at the very
bottom of the plans) so the shipbuilders can enlarge or
'scale-up" the plans to make and position the full-size
pieces of the boat.

Week 36: May 8-14
There are many vital, though unglamorous aspects to boat
building. The never ending saga of bucking and
splitting wood comes to mind, as does the constant
cleaning and sweeping up.
Staging is another example.
Climbing up and down ladders all day -especially with
hands full of tools or heavy loads- is not only tiring,
but dangerous. So staging is set up to create a
walkway around the whole boat. Ramps from the
ground as well as the shop (picture at left) make easy
access. The staging is reconfigured, raised or
lowered as the work focuses on different areas of the
boat.
Made of 2" pine boards using 6x6"
vertical posts and fastened with spikes, the staging is
solidly built to take the load of several men plus tools
and timbers. Staging is an essential part of
building the schooner ISABELLA. |

Week 37: May 15-21
Work on the deck progresses. The cambered beams
for the after-deck are in place, the plywood is on, and
is covered with fiberglass. A plywood and
fiberglassed deck is one of the few modern concessions
to this traditionally-built boat. The old time
laying of individual planks and "paying caulking"
between the seams is just too expensive to build as well
as maintain.
Francis and John are working on cutting out the holes
and fastening the stanchions -vertical "fence posts"
along both sides of the deck. A couple horizontal
planks will then be attached to the stanchions to
prevent crew from falling over the side.
Kerry has already
covered most of the rough interior with a coat of
protective (red) paint.

Week 38: May 22-28
While it's Harold's job to build the boat, it's the
Museum's job to interpret it to the public.
All winter the Museum has offered
tours of the Burnham shipyard, special demonstrations,
lectures, and events related to the ISABELLA.
Group visitors, of course, also get a special showing of
this "living history project."
School groups, for instance,
spend two-hours learning about why and how big wooden
boats are made, along with the 350 year old heritage of
building boats in Essex. They are put to work
bending planks, designing and building a small boat,
moving heavy objects with simple machines, etc.
The culminating activity is then to head over to the
Burnham yard to see up close a real wooden schooner
being built.
Here Kerry is explaining and
answering questions about ISABELLA to a group of 5th
graders. |

Week 39: May 28-June 4
While not everyone may be interested in wooden boats
(gasp!), building them today -especially large wooden
boats- is a unique and exciting event. Maggie
Holtzberg, Director of the Massachusetts' Folk Arts &
Heritage Program, interviews Harold as part of the
Traditional Apprenticeship award.
In between
down-to-earth replies to Maggie's questions, Harold
works on shaping the rudder aperture (the cut-away area
either side of the propeller shaft). By removing
unneeded wood and rounding the edges, he reduces
turbulence (i.e. drag) making the boat more
hydrodynamic.
The tool of choice for this job
(which can be seen in his hands) is -yes, you guessed
it! An adze! For some tasks the old tools
are still the best. |

Week 40: June 5-11
While designed and built in the same manner as Essex
shipbuilders have been doing for the past 350 odd years,
sometimes modern (power) tools or materials (e.g. epoxy
and fiberglass cloth) are used where for financial or
safety reasons it makes more sense.
In the foreground,
Francis is spreading epoxy around the stanchions where
they go through the deck. These need to be
water-tight.
Jeff, in the background is working on the transom.
A double layer of plywood (i.e. modern material) has
already been fastened to the forward side of the
transom. Jeff is busy hanging the bowed oak planks
on the backside.

Week 41: June 12-18
Life may seem complicated, but as every elementary
student knows, using simple machines makes life easier.
How do you move a
6000 pound lead keel without someone losing a toe?
How do you raise a large, heavy sail with only one or
two people? How do you quickly jam a rapidly
cooling, steaming plank up against the previous one so
you can fasten it in place? How do you split scrap
wood so it is small enough to fit into the wood stove?
How do you make a hole to put the trunnel in? How do you
lower a new 55 hp diesel engine down into the hull?
And just how do you get a wooden boat with several tons
displacement into the water anyway?
Whether a lever,
pulley, inclined plane or wheel all (complex) machines
are made up of these four components. Go ahead and
try not to use simple machines every day. Unless
you're in a comma you cannot do it. If you typed
on a keyboard or clicked a mouse to get to this page
then you have used a simple machine: your fingers are
levers!
(Answers to above
questions in case you were not sure: rollers and
levers; block and tackle; wooden wedge; splitting mall
-i.e. wedge with a lever; drill, which is an inclined
plane wrapped around itself; chain-pull -i.e. block and
tackle; wedges and levers along with some grease and
gravity). |

Week 42: June 19-25
Work begins on the foredeck. The curve of the boat
as it comes to a point in the front is clear to see, as
is the need to steam the thick oak planks to get them to
take such a bend. The starboard-side clamp (i. e.
horizontal plank on the inside upper edge) is still
temporarily fastened before being screwed in place.
The gentle curve of the deck beams going from one side
of the boat to the other is also evident.
While difficult to see because of
the criss-crossed staging planks, over a foot of (rain)
water is sitting in the bottom of the boat. While
this may seem like not a good thing, it actually is.
The water keeps the planks from drying out.
Besides, if the boat can hold water on the inside then
it also can keep water on the outside. This will
come in handy when the boat is launched! |

Week 43: June 26-July 2
Everyone pitches in to help. Leo, the owner's son,
is busy sanding the last few top planks. Note the
dust cloud!
Leo has been
stopping by throughout the building of the ISABELLA to
help out with whatever the day's project is. It all adds
up, plus he will have a solid understanding of how the
boat is built and where everything is. Go Leo! |

Week 44: July 3-9
The spars are ready...
These are beautiful pieces of art. You just want
to hang them above the mantel; they are much to nice to
be out in the sun! Rick and Dave have done a great
job crafting these. They started life as a fir
tree, showed up at the shipyard as 2x10 planks, and are
now rounded, tapered poles (up to 40').
The funny-looking round things on the rope are called "parrel
beads." They go around the vertical masts and hold
the spar against the mast. They are round so the
sail and spars can easily be raised and lowered.
The top horizontal spar is called the "gaff." The
bottom horizontal spar is called the "boom." There
is one each for both masts. |

Week 45: July 10-16
Are those some of the largest dovetail joints you have
ever seen? Nate has been busy building a
heavy-duty box surrounding the aft deck hole. A
water-tight cover will eventually go on top, providing
access to the engine compartment.
The ship's wheel is also (temporarily) in place.
Everything is coming along nicely and everyone is now
thinking about the launch. But when?
Well, only Harold knows for sure, but it won't be long! |

Week 46: July 17-23
All winter, when you have on so many layers of clothes
you can barely move, it hurts to take a deep, cold
breath, and you spend breaks next to the hot wood stove
in the loft, you dream about warm weather.
Be care what you wish for: you might get it.
The temperature has been in the 90's for the past few
days; the sun beats down for hours at a time. Man,
is it hot! Nevertheless, the work goes on.
The foredeck is now on and covered with fiberglass.
Harold (red shirt) is chatting with the crew early in
the morning. Everyone is thinking about how hot
it's supposed to get later in the day...and wishing for
the weather to break. After all, winter wasn't
that bad, was it? |
|
|
Week 47: July 24-30
We have a launch date! Sunday, August 13th at high
tide.
Like a Rubik's Cube there seems to be so much still to
do that it cannot possibly be done, but somehow the last
few pieces will go quickly and everything suddenly all
fall into place in time for the launch.
The foredeck cabin
trunk takes shape. The darker, orange-colored
boards are mahogany. A crew member shapes the
edges of the trunk with a router. In the bow, the
slot for the bow sprit is visible; in back of it is the
post (still to be finished), which will be used to tie
lines to when the boat is at anchor or against a dock.
Another hot week. |

Week 48: July 31-August 6
Only one more week till launch.
Jeff is still working on the transom at one end of the
boat. Bob is quietly seated on a staging plank in
the shade of an umbrella carving the name of the boat up
in the bow. Harold's son Alden, a friend,
and another crew member are busy applying putty in the
plank seams (hidden behind the side staging).
Aaron is working on more deck projects. Dave and
Stan are tarring the rigging. And a couple other
crew members are working in the shop. Harold is
overseeing everyone as well as dealing with the myriad
launch details. Whew!
Yes, the boat is pink with a lovely green stripe!
No, these are not the final colors. The pink
provides a nice contrast when doing the final sanding
and shaping of the hull. (It is kind of cute
though, don't you think)! |

Week 49: August 7-13
3:00 p.m. Sunday, August 13, 2006. A gorgeous
day. After a brief ceremony, the ISABELLA slides
quickly and gracefully into the full waters of the Essex River.
Hundreds of people have come to watch history come alive. Launchings were
once so commonplace that people barely turned their
heads to watch. Nowadays, the launch of a new
Essex vessel is a rare and stirring sight. |

Week 50: August 14-20
The boat may be in the water, but there is still much
work to do. The spars -vertical masts and
horizontal booms as well as bowsprit- need to be added.
The last of her ballast needs to be put in to adjust her
trim in the water. Not to mention all the gear,
such as extra line, anchors, lifejackets, etc. Plus a hundred
other last tasks to finish before she is ready
to sail away. No rest yet: the crew stay hard at it. |
|
|
Week 51: August 21-27
Here she is! It took months of work to create her,
but finally she is free of the land. With her
wings unfurled she heads along the Atlantic coast.
The Essex-built schooner ISABELLA.
