FINDINGS
In
Apri1, 1999, the vessel was inspected at her berth in Santa Barbara
Harbor at the request of her owner, Mr. William Allen.
Immediately
observed prior to boarding was the lack of fairness in the topsides
planking. Closer inspection revealed six to eight planks fractured
vertically across their grain at a frame location about eight feet
abaft the stem. This same condition was found in all the planks of
the transom at centerline.
Other
signs of trouble in the planking were noted, including proud bungs,
various fillers, signs of movement at the stem and transom corners,
and unfair plank seams.
Once
aboard, the odor of mildew and rot was unmistakable; further
inspection would uncover the sources, which included the entire
weather decks’ plywood sub-deck, planking, frames, beam shelf, and
many other structural members.
At
this time, the decision was made to haul the vessel for further
inspection at Ventura Harbor Boatyard.
“Elvica”
was hauled April 26, 1999. The hull was wooded and a thorough
inspection was performed.
Found:
1. Vertical cracks through several
planks about eight feet abaft the stem from the
sheer strake to the
waterline port and starboard.
2. Every transom plank cracked
vertically through at the centerline frame.
3. Rotted plank ends right forward
at the stem from sheer to waterline, port and
starboard, and aft at
the transom.
4. Rub rails severely rotted, especially amidships, port and
starboard, as well as the
planking underneath.
5.
Nearly
every frame severely rotted at deck level, some to such an extent as
to be
easily removed by hand.
6. Foredeck line lockers’ plywood
highly deteriorated due to delamination and rot.
7.
The main weatherdecks were found to be suffering from an
advanced state of
plywood rot and/or delamination, while the teak
overlayment exhibited open seams,
checking, and trouble in the bungs
and fasteners. After the interior paneling was
removed in the
forecabin area, evidence of extensive deck leaks was found in the
form of heavy streaking down the inner hull sides planking, rotted
deck beams,
rotted beam shelves port and starboard, and stains on
some bulkheads.
8.
The inner bulwarks plank, port and starboard, was rotted from
its forward end at
the stem to
about 20 feet aft. The blocking between these planks and the sheer
planks was
likewise deteriorated as well as the frames’ upper ends.
9.
The upper 10-20 inches or so of the stem was severely
softened in various places;
since the damage was not extensive, the
timber was drilled vertically in many places
and treated with
slow-cure penetrating epoxy over several days with good results.
10.
The first two broadstrakes above the garboards port and
starboard were cracked
vertically in
several places and exhibited damage to the seams, suggesting over
caulking.
Upon removal of these two planks stem to stem, the frame-to-floor
timber
bolts were
found to be completely deteriorated, having been made of yellow
brass.
Being just
over 1/4” diameter, they were replaced with 5/16”
bronze carriage
bolts, two
per frame.
11.
Once the topsides and transom planks’ removal began, it was
discovered that the
entire hull
above waterline had been fastened with yellow brass screws, most of
which had
deteriorated to mere powdery nubs between planks and frames. The
planking was
so loose that, once started, whole sections could easily be removed
by hand. The
transom planking had been fastened in the outboard ends and at
centerline
with scores of large stainless steel screws in an effort to hold it
together.
12.
A general “looseness” was noted throughout the hull
topsides planking, and, once
the teak
caprail was removed, the foredeck bulwarks could easily be moved
inboard and
outboard over an inch each way.
It
was therefore decided to reinforce the entire structure prior to any
further plank removal to prevent the hull from becoming misshapen.
This was achieved by installing laminated oak frames fastened
externally to the hull with heavy screws passing through the
planking and well into the frames, thereby creating an external “mold”.
And
so began the replacement of the thousands of pieces of timber that
make up the hull and deck structure from just below waterline to the
caprail. The repair is far beyond the scope of this report, and it
should be mentioned that “Elvica” was in perhaps the worst
condition I have seen in a vessel still afloat, and there is little
doubt that an adventure offshore or in a heavy sea would have led to
disaster.
In
an effort to simplify the remainder of this report, the items below
shall be as brief as possible; as a general rule, timber was
replaced simply because of rot, delamination, or otherwise soft or
poor condition.
Hereinafter,
when the term “laminated” or “glued” is used, it will be
referring to the exclusive use of Gougeon Brothers epoxy, and the
method whereby the surfaces of the pieces to be “laminated” or
“glued” are first wetted out by brush, then a second, thickened
coat containing Gougeon Brothers’ #403 microfibers is liberally
applied, and the pieces then clamped and/or fastened together.
All
of the new hull planking, inner transom planking, inner bulwarks
planking, and the 3/4” thick tongue-and-groove foredeck
underlayment are of quarter-sawn, (vertical grain) air-dried select
Douglas fir, being entirely free of heartwood, sap wood, knots, ring
or wind shake, and averaging less than 16 annual rings per inch.
All
of the new 12,000+ hull and deck fasteners are of silicon bronze;
the hull, transom, deck planking, caprails, blocking, and inner
bulwarks planking being fastened with 2-1/2” #14 slotted bronze
screws.
All
of the bolts described below are likewise of silicon bronze, with
the exception of the new windlass mounting bolts, which are of type
316 stainless steel, with heavy nuts. All timber was well painted
with two coats of red lead substitute prior to installation, with
special attention being paid to end grain.
The
term “bedded” refers to the process of the liberal application
of”Dolphinite” brand bedding compound, slightly thinned with
boiled linseed oil and/or red lead substitute, to all faying
surfaces prior to installation of timber above waterline. All
fasteners and bolts were likewise dipped in this compound for
protection and, in the case of screws, for lubrication. Below
waterline, timber and fasteners were similarly treated with a mix of
tar and red lead substitute. Special attention was paid to the areas
of the stem rabbet, transom corners, sub-deck and other blocking,
bulwarks planking, and cabinhouse-todeck corners.
“Epoxy
saturated” refers to the method of treating damaged timber with
continuous “floods” of “Smiths” brand penetrating epoxy
until the affected timber will no longer
accept further treatment. This method was also used to saturate
plywood edge grain and surfaces prior to installation. All the new
1/2” marine fir plywood was first cut and fit, then pre-drilled
for fasteners and saturated with “Smith’s” penetrating epoxy.
Two coats of epoxy primer was then applied, then two final coats of
white paint, with special attention being paid to the edges.
The
three main factors contributing to “Elvica’s” deterioration
were:
a. Sub-standard materials, i.e., the exclusive use of Philippine
mahogany throughout the hull planking, transom, blocking, etc.,
brass fasteners, and a luan plywood sub-decking of inferior quality.
b. Sub-standard to poor workmanship throughout in many areas
including rough, unfair plank seams, plywood installed with dry
edges, lack of bedding compounds in strategic places, and generally
poor fits throughout.
c. Design flaws, especially as regards the lack of drainage
considerations wherein fresh water could stand for days on end in
the frame bays throughout most of the
weatherdecks. This problem was exacerbated due to the entire bridge
deck draining
onto the lower levels, especially on wet, dewey nights. A toe rail
will be installed right
at the outboard edge of this upper deck and, once “Elvica” is
afloat and back on her
proper lines, a single large drain will be installed at the lowest
point just inboard of the
rail, thereby evacuating the majority of the upper decks’
drippings. (Please see
upgrades below)
1. The Transom
a. With the external “skeleton” in place, work began on the
transom while the hull planking material was “stickered” and the
air-drying process began. The lower three planks were removed first,
allowing access to the thirty or more brass bolts
that held the transom framing together; these were highly
deteriorated and often
crumbled upon extraction; most were of rather smallish diameters for
such large
timbers, and so were replaced with heavier, bronze carriage bolts,
well dipped in
tar prior to installation. Fortunately, the entire transom frames’
structure was found
to be in an “as new” condition; being of red meranti it held the
new screw fasteners
quite well.
b. A small pocket of rot was found in the uppermost, forward
outboard starboard
frame; material was cut back several inches past
the rot and a graving piece
installed.
c. The inboard transom bulwark plank, located just beneath the
teak caprail, was
rotted at both outboard ends and exhibited many
small past repairs, i.e., graving
pieces, epoxy fillets, etc. It was
replaced with a new plank of fine, air-dried
Douglas fir.
d. Planking now proceeded by installing a Douglas fir inner
plank 3/4” thick and well
bedded on the frames followed by the outer teak planking, 7/8”
thick, bronze
fastened and well glued to the fir with Gougeon Brothers epoxy
and cotton fibers.
The seams lap by over one inch and the outer seams are tight
and glued to accept
a bright finish. This process continued upwards, removing old
planking one at a
time while installing a glued “pair” as described above
each day over a period of
perhaps two weeks while other work proceeded elsewhere,
thereby allowing each
new pair of glued planks to cure for a day before proceeding
further.
e.
The transom was then sanded fair, and five coats of marine
varnish applied. Further coats will be applied by the owner.
2. The Frames
As
stated above, every frame, port and starboard, stem to stern, was
rotted at and below deck level. Believed to be of yacal, they
measure two inches wide, sided 1-3/4” and are on approximate 12”
centers. They were all replaced and/or “sistered” from the sheer
down into the hull; timber was removed several inches beyond the
damage and to reach logical joint locations, i.e., plank centers,
longitudinals, or merely to avoid stopping at a sharp curving
section. With the temporary outer frames in place, hull movement was
no longer a concern, and framing proceeded as follows:
a.
Short sections of every third
plank or so was removed, thereby allowing access for clamping, etc.
b. A laminated white ash sister frame was installed
using the old planking as a mold, and extending down into the hull
as far as needed for frame continuity. Most were extended downward
to and/or beyond the lower longitudinals and well fastened there.
Temporary fasteners were installed one per plank to tighten things
up, then the shorter upper section replacing the damaged original
frame, was installed similarly. After cure, each pair was dressed
off, then bolted to each other fore-and-aft with 1/4” carriage
bolts at appropriate locations. They were then painted with red lead
substitute. The blocking to carry the six bronze ports was also
replaced during this process.
c. As work progressed aft, it was noted that the frames in the
quarters, down around the sharpest turn of the bilge, had been
deeply scored at the plank seams, such as one would expect from a
thin kerfed saw, and cracks had started there. A small plank in this
area was removed port and starboard, and 9-foot long sisters were
installed from the sheer, down around the turn of the bilge, and
beneath the bilge longitudinals, and well fastened there, five per
side, or about every third frame.
d. As framing proceeded in the quarters, planking was begun in the
bows, starting with the sheer strake.
3.
The Hull Topsides Planking:
To
retain the proper sheer lines, the heights and top bevels of the
frames forward were copied exactly one by one during removal for
fmal reference when planing the sheer. The exception to this was an
area about 16 feet long on the starboard side, for it was found to
be rather flattish and not matching the more lively “powderhorn”
of the port side. The frames here were therefore extended by eye
about 1/4” with later good results.
a. Experience has shown that on this type of hull, wherein
the first three upper planks fall on frames exposed to the sky and
are unsupported by any timbers other than the planking, it is unwise
to attempt bending planks cold or even steamed, for the forces
exerted inward can cause the frames’ upper ends to move slightly
inboard, causing a “pinched” look at the sheer rather than a fme
flair.
Also,
these first several upper planks, when cut to shape and laid flat
describe a rather extreme “5” curve and, if one desired to have
these planks extend from the stem to the bulwarks gate area aft in a
single piece to avoid a butt joint in the sharp curve, the plank
stock would need to be some thirty feet long and over thirty inches
wide. This, of course, would cause these upper planks to have
extreme grain run-off at the bows.
Lastly,
in the area of the large bronze opening ports, two planks above and
below one another are cut nearly through their widths to receive the
ports, leaving several areas just under one inch in width. Since the
planks here have quite a lot of bend and twist, the fear of a
fracture is quite real and did occur in the original planking.
With
all these considerations, it was therefore decided to scarf and
double-plank the entire bow area from the sheer down to one plank
below the ports, laminating the doubled planks right in place upon
installation, using the screw fasteners and various clamps overnight
to achieve a good lamination.
Further,
as each full-length plank was installed, it was edge-glued with
epoxy and fibers to its neighbor.
The
inner planks are 5/8” thick, the outers being 3/4” thick to
achieve the original hull thickness of 1-3/8”.
The
scarves were angled to create the rough shape or profile of the
planks, and are of the “spar” type, being at about a 20 to 1
length-to-thickness ratio.
Lumber
for this process was ordered well in advance, milled to proper
thickness,
and air-dried for about 3 months while the other work described
above proceeded.
b.
The bulwarks planking aft in the quarters was installed full
thickness (1-3/8”) but
similarly edge-glued to avoid the usual cracking seams associated
with planks
exposed to the elements on both faces. Several scuppers were let
into the plank at
deck level here to evacuate water between the frames.
c.
The ninth plank down from the sheer at the bows, which runs
just below the
planking at the ports, aft beneath the gate and
further aft still to the stem, was also of
full thickness and its
top edge glued to the planks above. From this plank down, the
seams
are not glued but caulked in the traditional manner with a single
strand of cotton
and seam compound.
d.
Planking now proceeded upwards from just at the waterline to
one plank away
from this ninth plank, where work stopped briefly in order to clamp
and laminate the
new rubbing strakes in place. They were left to cure here for three
days, then
pre-drilled for the 6” #24 bronze wood screws, which pass through
the rub rails, the
hull planking, and well into the new framing. They were then taken
down for final
shaping and sealing, and a 1-1/2” x 1/4” type 316 stainless
steel strap was welded
into two 32-foot sections for chafe guards, pre-drilled and fit to
the rub rails, then
polished, both for appearance and to prevent surface rust, prior to
installation.
e.
While all this was going on, part of the crew was kept busy
removing and replacing fasteners throughout the entire bottom, as
well as the frame-to-floor bolts mentioned above. We were able to
extract nearly 100% of the #12 x 2-1/4” screws which were replaced
with over 3,000 #14 x 2-1/2” silicon bronze wood screws, well
dipped in tar.
f.
Finally the shutter planks were installed, seams caulked, and
the topsides sanded fair. The seams were routed into 1/4” “coves”,
then the entire topsides sealed with several “floods” of
penetrating epoxy to stabilize the timber and create a good base for
paint and primer. This required 10 gallons of Smith’s penetrating
epoxy.
g.
The caulked seams were filled with “Sika-flex” 241
compound, and the hull then primed with Proline 4069 primer by Dale
Morris and crew of Exotic Coatings, Ventura.
h.
The rub rails were similarly sealed and primed while off the
boat to get good coverage beneath them, then were well bedded and
installed.
i.
It should be noted here that all the topsides butts were
located well beyond any areas of severe bend or twist, and no single
piank contains more than one butt. All plank ends were well
saturated, then glued to the fir butt blocks, and fastened. The
choice of fir for butt blocks was based on its
excellent
gluing properties and resistance to rot, problems often associated
with some hardwoods. All butts are located a minimum of two planks
and four frame bays from one another, and some of the topsides
planks are nearly 40 feet long.
j.
Once the usual glazing, sanding, and re-priming was
completed, three fmal finish coats of Stirling 1001 white linear
polyurethane were applied “wet-onwet” by John Burman of Exotic
Coatings.
4. The Foredeck:
a.
When walked upon, a “squishiness” could be felt
throughout most of the foredeck, indicating trouble beneath. Several
teak planks were removed, and the 1/2” plywood underlayment was
found to be severely rotted and delaminated to such an extent that
one could separate the plies as easily as a deck of cards. The
entire deck was hauled off, and the damage was found to have spread
to the deck beams, blocking, breast hook, and the forward most
sections of the beam shelves.
b. A quick mold was made using an area of the deck right over a
bulkhead, and, as work proceeded elsewhere, several
five-laminate fir deck beams were molded in place there and allowed
to cure for two or three days. Since a certain “flatness” was
noted in the foredeck, (perhaps due to sag in the sawn Philippine
mahogany deck beams) a slightly enhanced crown was built into the
new beams, with later good results.
c. New sections of the beam shelves,
port and starboard, were installed, bolted to each frame and
extending aft for about 14 feet from the stem to good timber, and
scarfed there.
d. The new deck beams were first fitted and drilled for bolts,
then taken down and painted, saving hours of labor and getting a
more thorough job. The beams were then bolted in place, and
temporary shoring was installed at there their centerline underneath
for support while the deck was being laid.
e. The breasthook too, was rotted and of rather smallish
dimensions. Since “Elvica” is to be used for extensive cruising
and carries a heavy windlass, it was decided to extend the
breasthook right back to the chain locker bulkhead. It is built of
clear fir sawn to the deck crown, bolted to the beam shelf, stem and
bulkhead. It is laminated together and fastened fore-and-aft through
the laminates with 3/8” x 6” bronze lag screws.
f. The foredeck line locker and hatch assembly was
unsalvageable and so it too was hauled off and discarded.
g. The original plywood underlayment landed on a deck beam right
forward of this hatch and was fastened there. However, a 2” wide
teak margin board running athwartships caused the plank ends to land
only on the ply where they were fastened, with the screws poking
down through the ply. Also, the plywood sub-deck was obviously built
before the house superstructure, which sat atop it. These and other
construction techniques caused hours of tedious labor hand cutting
the ply back to sound timber. The remaining ply
beneath the house’s forward ends was then well saturated with
epoxy. A short section of deck beam was added centerline at the
hatch to accept fasteners, and strong cleats were installed down
along the house forward perimeters to accept the planking.
h. Before closing everything up, existing timbers and paneling
was saturated with wood preservative to ward off mildew and rot. The
exposed top edges of the various bulkheads were similarly treated,
then painted with two thick coats of red lead substitute.
i.
Now the fir blocking was installed outboard of the beam
shelf, to which each was fastened with two 2-1/2” #14 silicon
bronze wood screws and well bedded. Two more screws coming in
through the hull planking fmished the job, and now the deck would
have an improved, strong perimeter to fasten to.
j. New
“sub-marginboards” of 1” thick fir were sawn into shape and
let into the deck beams. They extend from the breast-hook to the aft
end of the foredeck.
k.
While this and other work continued, Glen Scotland of Exotic
Coatings was kept busy sealing, priming and painting the many nooks
and crannies created by all these timbers that would later be
difficult or impossible to reach once everything was closed up.
l.
During this period, much old wiring and windlass cables, etc.
was removed, the mounting holes and such being filled with thickened
epoxy and faired prior to painting.
m.
m. Next came the sub-deck. It was built of air-dried
vertical grain clear Douglas fir 3/4” thick. A “king plank”
about 6” wide with tongues outboard was installed at the
centerline, the remainder of the tongue-and-groove planking being
about 3” wide. All the planks are full length and edge glued to
their neighbors. They are fastened at each deck beam, blocking,
breasthook, cleats and sub-margin boards with 1-3/4” #14 silicon
bronze wood screws. Prior to installation they were lain flat with
their lower faces to the sky and sealed, primed and painted.
At
the perimeters in way of the breasthook, blocking and cleats, they
were heavily bedded, and once in place, epoxy was literally poured
into the seams, creating a strong sub-deck which was itself
watertight. After cure, it was sanded fair and several “floods”
of penetrating epoxy applied.
n. Finally,
the teak decking was laid. It is of 3/4” thick, clear Burmese
teak, with fine vertical grain throughout, having been carefully
selected and
milled on site. A 5” wide
“king plank” was installed centerline, the remainder of the
planking being 2” wide. All run full length with no butts. These
planks were fastened to each deck beam, breasthook and carlins with
2-1/2” #14 silicon bronze wood screws so that fasteners pass
through the sub-deck and well into the timbers beneath.
The
deck was glued down with 3M 5200 black adhesive and plugged. After
cure, the plugs were ground off, followed by a thorough vacuuming of
all the weatherdecks. The seams were first washed with acetone, then
primed with two coats of “Detco” primer, and fmally filled with
“Detco” deck caulk, which required 5-1/2
gallons.
o.
Next came the margin boards, but before proceeding further, I
must say that I have always disliked the look of nibbed margin
boards on broad foredecks wherein the deck planks are laid dead
straight to the centerline, as is the case with “Elvica’s”,
for to prevent shrinking and/or “cupping”, etc., the planks need
to be quite narrow, and therefore numerous to cover such a broad
deck (nearly 60 planks in the case). The resulting myriad of nibs in
the marginboards are very time consuming and can look very busy.
Secondly, experience has shown that the seam compound can tend to
shrink or pull around the numerous turns and corners of the nibs,
resulting in deck leaks as the caulking ages. Also, that little
corner where one nib ends and another begins, is quite fragile and
can come adrift if exposed to long periods of hot, dry weather.
Since one of the major contributing factors to “Elvica’s” near
demise was deck leaks, I had decided far in advance to re-design the
deck perimeters, using methods previously applied to similar
vessels:
1. The margin boards of the sub-deck, being of fir, extend inboard
from the hull about 9”, allowing the hood ends of the sub-deck
planking to fall about 1-1/2” onto the sub-marginboards, which are
of 1” thick fir and let into the deckbeams.
2. The teak deck plankings’ hood ends overlap the fir sub-decks’
hood ends by about 2” and are cut along a fair curve sprung with a
batten.
3.
The teak marginboards are 1-1/4” thick and are rabbetted
1/2” over the planking’s ends, swimming in adhesive and well
fastened with 2-1/2” #14 silicon bronze wood screws to the deck
beams, sub-marginboards and blocking. They are of fine, vertical
grain teak and have a single butt joint in their foot lengths, which
is splined. The inboard edge is 20+ builnosed for appearance and
wear.
4.
Filler blocks of teak were installed outboard against the
hull planking and
between the frames.
5.
Finally,
teak blocking was installed above, extending out to the frames’
inner faces from the hull, and having a slight slope inboard to
prevent water standing in the frame bays.
5.
The Aft and Side Decks:
a. Same sad story here, with the exception of the deck beams
and beam shelves, which were found to be in excellent condition,
though four beams’ outboard upper ends, right at the gate
portside, were somewhat softened. They were cropped back to good
timber, and wedge shaped graving pieces installed.
b. Under the portside deck was found
some ancient sound insulation, which was immediately hauled off and
replaced with new high density foam.
c. One maddening discovery was the 1/4” and 1/8” luan ply
shims used in faiing the outboard deck line and located between the
beam ends and the shelf. These were highly deteriorated and so were
replaced with new ones of white ash one at a time, and were well
painted and bedded.
d. The outboard blocking was just rotted away, and in any case
seemed rather withy and haphazard, being of many varied sizes and
shapes that suggested a whimsical carpenter, high on opiates and
having a grand time installing blocking under a full moon. Some were
mere 1” x 1” cleats screwed to the hull planking, while others
just rolled around in there, supporting little or nothing.
Never
can enough be said about the importance of good sound methods being
employed in this area, for good blocking is a first and last defense
against deck leaks, and creates a strong perimeter to carry the
decking.
The
new blocking, which runs from the air intakes forward on the
portside to the transom and from the transom starboard side to about
15 feet forward, was installed as follows:
1. An outer block which lands
between each frame and extends down the outboard face of the beam
shelf, and is fastened there. Its upper end picks up the correct
height and bevel of the deck beams.
2. An inner block, which sits atop
the beam shelf, fit snug between the beams and fastened to the outer
blocks and to the frames. They, too are beveled along their top
edges to accept the decking.
3.
All the blocking, including those in the foredeck, are of
clear, air-dried Douglas fir, 1-3/4” thick. The double blocking
aft therefore creates a continuous 3-1/2” wide perimeter for the
decks to land on. They were first cut and fit, then pre-driuled and
numbered, then made to stand end-grain down overnight in wood
preservative, then next day turned over to stand another night on
their other ends.
4. They were then installed, well
painted and bedded.
e.
The aftermost deck beam, which is a large sawn timber right
aft at the transom, was found to be in an “as new” condition,
and at the request of the owner, blocking was installed between this
and the next two beams forward and extending inboard from the hull
about three feet in order to support a small windlass or turning
block at some later date.
f.
The deck beam which supports the aft end of the house was not
of sufficient width to accept fasteners for the teak decking,
(similar to the problem on the foredeck) and so a full length, full
size laminated beam was added and well fastened to its after face.
g.
The lazarette hatch was a poor affair, and besides it was
quite small, being only about 18” x 22” and was located about a
foot off centerline. Since the carlins were somewhat softened
anyway, the entire assembly here was hauled off and a new, larger
hatch with an improved drainage and dogging system, was installed.
h.
The house perimeters were ground along their lower edges and
sealed with “Smith’s” penetrating epoxy.
i.
The 1/2” fir marine plywood sub-deck came next, but not
before the fittings and tops of the tanks were treated with “Ospho”
phosphoric acid, then brushed with cold applications tar to prevent
further rust. The sides and bottoms appeared to be in a nearly “as
new” condition. The fuel tanks received new copper tubing vents,
and the iron filler necks were replaced with stainless steel. New
bronze deck caps were installed.
j.
3” fiberglass tape, saturated with Gougeon Brothers epoxy,
was installed all around where the plywood sub-deck meets the house
sides.
k.
Finally, the 5/8” teak
decking was installed, similar to that on the foredeck, with the
exception of the marginboards, which here are flush with the
planking, for between nearly every frame from the gates aft,
scuppers had been let into the hull planking, and sloped blocks
installed in those frame bays without scuppers.
l.
Just aft of the steps leading to the foredeck, port and
starboard, three frame bays were employed to act as air intakes,
such as one sees on seiners and other commercial vessels.
6. The Bottom:
a. When sounding the bottom with a heavy rubber mallet,
one is supposed to listen for the “bonk” from sound timber, or
the “thud” of softened planking or frames. Sometimes, as in “Elvica’s”
case, a distinct “clack” can be heard, the unmistakable sound of
the mallet hitting a plank, then the plank hitting a frame,
indicating problems with fasteners.
b. Several 2-1/2” #12 silicon bronze wood screws were
pulled, and most were found to be in fair condition, exhibiting the
usual greenish patina, with some leaning more towards that pinkish
state they turn when nearing life’s end.
c. Since most backed out quite readily, it was decided to
re-fasten the entire bottom, using 2-1/2” #14 silicon bronze wood
screws into the original holes, with the exception of perhaps the
150 or so that snapped off; these were re-drilled at a slight angle
and re-screwed.
d. Upon installation of each and every fastener, it was
noted that the planking moved inboard slightly, from a minimum
ofjust being perceived to a maximum of nearly 1/4”, indicating a
re-fastening in the not-too-distant past wherein the installer
simply failed to tighten the screws properly.
e. While installing fasteners,
several things were noticed in the original bottom planking:
1. Many areas of softness in the planking, in some
places to such a degree that one had to be careful when fastening
not to drive the screw right through. “Widespread” is not quite
the right description, though the condition exists in many seemingly
isolated places such as the area near the stem above and below water
and for several feet aft, around zincs, near waterline aft, and the
third plank, or broadstrake up from the garboard.
2. Cross-grain fractures in the planking near the bow.
Hard to see and depth unknown.
3. The oakum driven into the seams,
probably during construction, was very dry, hard and loose. The
whitish, now powdery seam compound was easily sloughed away with the
lightest tools. Since time and financial considerations did not
permit complete reefmg and re-caulking nor a new bottom, the
caulking was re-set and soaked with red lead substitute, then the
seams filled with tar.
4.
Very rough plank seams, and damage to the top edge of the
garboards, suggesting
zealous over-caulking. Fitting new planks alongside the existing
planking proved to be somewhat difficult, for instead of fair, flowing
plank lines, we were faced with ones that resembled highway 33, most
notably on the port side.
5. “Bum”
around some through hulls and especially the large bonding zincs just
below the turn of the bilge, starboard side. Here a seam was quite
open and dried out to such an extent that one could see friends inside
fussing over the engine. It was carefully re-caulked and, due to its
grainy dryness, should take up and stop leaking after a weeks’ time
or so. See “Summary” below.
f.
Finally, the last of the new planking was installed, being the
first two broadstrakes port and starboard just above the garboard and
extending from stem to stern, with a single butt each. Caulking and
paying of the seams was fmished December 27, 1999 and the bottom
painted.
7.
Miscellaneous Repairs and Upgrades:
a. Improved, larger breasthook
b. Relocating air intakes, while
increasing their capacity by about 300%.
c. Larger, much improved lazarette
hatch.
d. New swimstep, with end grains
protected by sacrificial pieces, and of heavier scantling.
e. Toe rails at perimeters of bridgedecks for safety and water
diversion.
f. Scuppers in aft bulwarks for
evacuation of standing or sea water.
g. Improved foredeck (see above).
h. A 2” thick teak pad was installed beneath the
windlass - this should give the chain a more secure angle from cat to
roller.
i. Windlass moved forward about 3”, causing the
chain to fall straight down into its locker rather than the sharp turn
of the original hawses.
j. The double planked transom is very strong and fair,
and the bright fmished teak greatly enhances “Elvica’s”
appearance and value.
k. Ventura Harbor Boatyard personnel
replaced every thru-hull with new bronze ones, as well as the valves,
hoses, connectors, etc., for the five bilge pumps, generator, deck
washdowns, drains, and head intakes. Everything was double clamped.
Jim Wulif and Associates installed a new engine intake thru-hull and
valve, knotmeter paddle wheel, and two new transducers and zincs, as
well as re-plumbing and upgrading the entire fuel system. The access
plates on the tanks were removed, the tanks cleaned, and new gaskets
and sight tubes installed.
SUMMARY
“Elvica”
was launched at 1:00 p.m., December 30, 1999, and within a few days
the hull had taken up quite well. Ventrua Harbor Boatyard personnel
aligned the engine, and she remained in her berth here for about two
weeks while miscellaneous projects and loading, etc., took place.
These
repairs to “Elvica” consumed over seven months and many thousands
of dollars with not a single day lost to bad weather. Even with my
many years of experience, surprises seemed to wait around every corner
each new day. In retrospect, this vessel should probably have been
destroyed; that is, if financial considerations were the sole driving
force.
But
now the structure is entirely new, or nearly so, from just at the
waterline and wrapping around the bulwarks, over the decks and to the
house sides. Throughout these areas, hardly an original piece of
timber is left, though the teak caprails come to mind.
The
construction methods employed were borrowed both from the new and the
old, taking advantage of modem adhesives and techniques where strength
and lower maintenance were important, yet not forsaking the ways of
the old timers when a time proven method or material was simply the
right thing to do.
The
hundreds of little jobs that always pop up in this type of restoration
were not mentioned above in order to keep the report as short-winded
as possible, though they have not been forgotten.
As
previously stated, the Philippine Mahogany bottom planking was found
to be in fair to poor condition, and until such time as the remainder
of the bottom can be replaced, “Elvica” should not be used for
extensive cruising.
Local,
coastwise trips should be planned around fair weather.
With
a new bottom of Douglas fir planking, “Elvica” should provide many
years of safe, trouble free service.
