Laser 28 Wanted

Update - I picked up Zapatero yesterday and she is now in the boatyard awaiting bottom paint, rigging and some other minor work.  Overall she is in dusty but in great condition and hope to be on the water in a week or so.  

Below is an extract we received when the boat was looked at by Chris Wilson from Vancouver. I also have a couple of photos of the repair, but they don't show much. See below:

An update on Zapatero's repair:
Once hauled, we found there were no cracks in
the hull laminate, just in some fairing putty
and the bottom paint.
[We actually drilled some cores through the cracks to make sure (added
comment)]
The structural grid had become disbonded from
the hull for a distance of about 1 foot, either
side of the sump. The sump remained bonded
and there were cracks that went completely
through the grid laminate with a length of an inch or two at the junction between the sump
and the transverse beams (floors).
We repaired as follows:
Cut out the structural grid for a total width of about 5 feet and for a distance about 6 inches
beyond the front and back ends of the keel sump. Ground out the grid laminate from the
sump.
Added 1.5 oz mat, 24 oz woven roving (WR), mat, WR, then two layers of 8.6 oz unidirectional
(uni) to the hull, including the sump. All were laminated with epoxy laminating resin. WR and
uni were S-glass. Unis were run in the athwartships direction.
Built floors from 2x douglas fir.
laminated mat, WR, and Unis over the dougla
s fir floors, using approximately the same
schedule as for the hull, above. Laminations extended across the entire area of the hull
laminated above.
reinstalled the original structural grid over
the new laminated grid. The old grid was tab-
laminated onto the hull with mat, WR and epoxy. cut joints in the old grid were ground out
and taper-laminated with mat, WR and polyeste
r resin, since the old grid was polyester.
Furniture is now being put back in the boat.”
Note
that
after
the
old
grid
was
cut
out,
we
added
a
considerable
laminate
schedule
to
that
entire
area
of
the
inside
skin
of
the
hull.
I
remember
that
the
worker
that
did
all
the
laminating
work
was
very
skilled,
but
understood
little
about
engineering
stresses
and
strains.
I
originally
had
designed
the
floors
to
be
replaced
with
the
same
shape,
with
PVC
foam
to
serve
as
molds
for
the
laminate.
He
wasn’t
happy
until
I
redesigned
it
with
Douglas
fir
molds
at
his
suggestion.
He
was
satisfied
with
the
“stronger”
Douglas
fir.
I
knew
that
the
core
material
was
inconsequential
in
this
particular
design.
Since
we
used
narrower
2x
lumber,
the
old
floors
fit
neatly
over
the
top
when
it
was
finished
(see
below).
I
visited
the
yard
at
Oceanside
regularly
during
the
repair
to
observe
and
discuss
the
progress
with
their
laminating
expert.
Note
also
that
there
is
no
mention
of
the
number
of
Douglas
fir
floor
molds
added.
2x
refers
to
the
type
of
lumber,
as
in
2x6.
One
was
added
at
the
location
of
each
of
the
removed
floors
from
the
original
grid.
Additionally,
I
added
a
Douglas
fir
mold
in
the
fore
‐
aft
direction
to
tie
in
the
ends
of
the
new
floors
to
each
other.
This
served
to
spread
out
the
load
from
the
ends
of
the
floors
to
avoid
hard
spots
or
stress
risers
in
the
hull.
Note
that
the
lamination
over
the
Douglass
fir
floor
molds
extended
across
that
entire
area,
including
the
hull
inner
skin.
We
tapered
out
the
edges
to
avoid
any
hard
spots
or
stress
risers.
Note
that
the
old
grid
was
replaced
and
the
cut
joints
were
ground
out
(with
a
taper)
and
the
taper
laminated,
in
order
to
restore
the
full
strength
across
the
joint.
I
would
argue
that
the
replaced
original
grid
is
as
strong
as
it
should
have
been
originally,
but
has
a
very
strong,
fully
‐
laminated
to
the
hull
(not
glued)
floor
system
underneath.
I’m
glad
I
posted
that.
It
served
as
a
good
reminder
of
what
we
had
done
7+
years
ago!

Thanks Bill! That was definitely a concern as far as whether the boat could handle the extra weight down there. I saw also in the forum that there had been some hull repairs done (searched the boat name) and was wondering if that was related. Not too concerned with class racing as there are only a couple of Lasers I can locate here in California. I think the boat sold a couple of years ago but not completely sure. I know it was listed.

PS. Love this forum. So much great information!

I am going to look at the San Diego boat today. Any quick pointers on specifics I should be aware of? Things to check or look for?

Thanks!!

Yes, this boat was for sail. I had a friend here in Vancouver who was interested and went down to have a look. He became a little discouraged because of all the things he would have to undo to make it a proper Laser again and was not up for the project, so gave up on it. It still seems to represent great value for someone who wants a boat to cruise with, or who has the time to get to work on her.

FYI, the first boat was #101 

Hi Vance,

Vance, you made the right decision regarding the New Buffalo boat.  I was aboard last week and dismayed at the lack of maintainance.  Surprising since the owner said he was an engineer. I "guestimatted" $20-25K to put in shape with new sails.

I am familiar with that boat and can relate that it is in excellent condition with full suit of race able sales, though not new. It is hull #242 so it is is actually the 142nd boat built out of 143. All new hi-tech running rigging, etc, and interior is in great shape. Owner wants a larger boat for wife and family. If interested I can put you in touch with owner. No trailer with this one, but everything else is good. Not sure the price, but guessing around $22,000.
