I did a whole lot of research and a whole lot more thinking before I made
the following decision.
A trip to Boston secured two 3/8" x 4' x 16' sheets of marine grade fir plywood
for the bottom and a sheet of 1" thick 4' x 8' Mahogany plywood for
the inner skin of the transom. I felt that old Mr. Rivenbark would agree
with
my thinking that the end result will be a stiffer, stronger boat. At least
at the stern.
I did have to remove 1/4" from the components of the motor well, as well
as the last two ribs to accommodate the change, but she now has a solid
piece from port to starboard instead of the pieced
together vertical planking which was held in place with
water based
glue and a few screws.
The new inner was carefully scribed and cut to fit the
planking, and thoroughly epoxied
into place ; 1 1/2" screws added through the planking and bottom framing
whilst the epoxy was still wet - I was sure to have enough 'glue' to allow
it to squeeze out all around.
The two Transom knees were epoxied into place, bolted
through the framing with bronze carriage bolts, and
screwed through
the forward frame and the
inner skin of the transom. The original layout had
been to bolt them in right through the bottom plywood.
This
was probably
not the best solution as the
heads had compressed the plywood over time and allowed
some leaking to occur around them, contributing to
the dry rot.
I opted for countersinking them into the 3 1/2" wide 42" long aft battens
which you may remember were already 1/4" thicker than original. I also
countersunk the heads into the inner skin of the transom, whereas the original
method
had been to bore a deep countersink into the outer skin and then install
a plug to fill the hole flush.
My way, though patently not original, leaves less
room for leaking.
Another trip to New England Hardwoods secured the
outer planking for the transom, a nice 5/4 x 12" x 12' mahogany
stick. This replaced the original outer skin of the transom right
down to the widths of the original pieces.
Each piece was fitted, then removed, coated in epoxy and re-installed with
a liberal coating on the mating surfaces between the inner and outer skins.
Clamps, and more 1 1/2" screws.
Mating edges were also epoxied assuring a perfect joint which should
not separate the way the original did.
All remaining screw holes were plugged with
birch dowels and white glue to assure a good grip for the new screws which
undoubtably would hit at least a few of the old holes.
I thought long and hard about if I should epoxy the bottom
plywood onto the frames, but decided against it in favor of a liberal
bead of Boat-Life white along all mating surfaces.
When installed ,
and screwed down (another 600 1" screws), the joint should prove to be
both secure and watertight, but allowing for removal of the sheathing if
necessary down
the road.
Next, after one final trip to the Hardwood store, I cut and set aside the
keelson and chine rub rails. This was because I coated the entire
bottom with WEST epoxy , rolled on with a 'foamie' then tipped off.
After that cured, I attacked it with my d/a sander and 120
grit. Yeah right.
I put that sander down and picked up my 3 x 21 belt sander,
and ground away the surface until it was smooth to the
touch. More vacuuming. Then I went
over it with the d/a.
Now I installed the keelson, and the chine rub rails, with epoxy behind
them. I also added something else which wasn't on the original boat. Two
short rails , 1 1/4" x 42" long, tapered to the same contour as the keelson,
set 7 1/4" off each edge of the keelson. These rails were on the Tojan
Marlin I refinished and added incredible stability to the boat at speed.
Now think
about this - the 80HP motor on the Barbour always had a tendency to try
to make the stern feel like it was racing to get ahead of the bow. Believe
me,
that's not a good feeling for the person at the helm when you're out on
the Hudson River! I'll let you know next week if they work on this boat.
If they
don't I can remove them easily.
Finally, I sanded again, vacuumed again and applied the final
coat of epoxy. (Incidentally, I did not put in any mesh
to the epoxy. I want to seal the
wood, not make a fiberglass one).
After sanding I applied the bottom
paint . I really wanted to use VC Liquid Speed, but
that product is now off the market, like so many other
good products,
so I applied Woolsey 604,
which also contains Teflon and has the appearance of the
original Woolsey copper bottom paint. There is a black
boot stripe to replicate the original,
and then white side planking which I like and was one of
the optional colors available for the Silver Clipper.
The 'Crew' helped roll
over the boat before applying the boot stripe and
side paint, and then the trailer was
slid in under the boat, which was hung from slings from
the garage rafters.
I actually didn't manage to finish putting the wiring back together (though
the hardware was on) before I left for vacation on the Sacandaga Reservoir,
but the Sea Trials were
a total success, with not a drop of water leaking into the boat.
I replaced the motor well bottom a few weeks ago, as it was pretty tired,
and that's as far as I go for this year.
I have run on the Hudson River, and for anyone who's interested, the extra
rails I added to the bottom made a huge difference in the handling of the
boat. She will now run flat out in a tight turn without any skipping, porpoising
or other questionable handling characteristics.
