What is the problem of the old fasteners ? As long as loose and obviously
corroded fasteners are removed and later covered in polyurethane adhesive
they pose no risk due to no continued moisture contact.

Air powered chisel, followed by a grinder?

You heard the one about the fire on the USS Oriskany? Someone
accidently ignited an air dropped illumination flare. Tossed it into
the locker full of flares, slammed the lid, and hid the problem for
about ten seconds.

US battleships had four inch thick teak decks. Weight was hardly an
issue, but can you imagine the cost at today's prices?

First off teak is not a heavy hardwood. A square foot of 1/4" x 1-5/8" teak
weighs 14 ounces.
Any teak deck that requires replacing has probably had that 1/4" worn off in
service.

Yes, that is the point and where someone competent is required to sample
areas of the old deck to
acertain if the subdeck is sound enough to apply a new 'top' deck.

Every cruise ship I have been on had teak decks. They didn't maintain
them, hosed them down, perhaps, and I don't know why they would wear
much if any. Traffic wouldn't do it, those things are big and the wear
would be well diluted. The planks were perhaps three inches wide, and
must have been maybe 3/4 inch thick? You need a certain thickness,
relative to width, to avoid cupping. Of course they don't have to
impress the neighbors with well sanded teak. I mean we saw one boxboat
in two atlantic crossings.

And your point is ?

I have been through a number of cruise ships at the 'ship breaking yards'
and , over years, watched teak deteriorate on the stump.

Do you believe that teak decking does not wear thin ?

I would be more concerned about movement in the old deck putting strain on
the veneered deck seams. I believe it would probably work but I would
suggest a layer of 6oz glass and epoxy over the old sanded and acetone
washed deck. Then take care to lay out the new deck with the seams
positioned over the center of the old boards.

Still there could be a problem with moisture from below. Especially if the
old deck is flat sawn rather than quartered. As the humidity on the back
surface changes the old flat or riff sawn teak could cup. That would put
some weird stresses on the new deck.

Potential moisture below the old decking is certainly the area of greatest
concern and may require lifting small sections of the old deck
to search for trouble spots. I would use a polyurethane adhesive rather than
epoxy and matting to allow for any possible movement .
I doubt that cupping would be a factor in a well weathered deck made up of
1.5 to 2 inch teak strips.


Thanks for your opinion..........Ken

I have a 1949 Chris Craft 33foot DeLuxe Enclosed Cruiser.
I hate carpet on boats if it isn't snap-in. I only like snap-in cause
it can be removed and cleaned off the boat, dried in the
sun, coated with scotchguard and put back in the boat, also it can be
removed for winter storage.
Also, after working for Olympic Boat Center and going on the tours of
Bayliner factories, I found that any carpeting from the factory is
the cheapest, most worthless carpet on the planet. But the carpet they
give you makes really good patterns to make your own.
And altogether, your looking at, what, 4-6 yards of really nice stuff,
to make your feet really happy?
And it isn't very technical either.
But I took all the carpet out of the saloon and put in 5/8 quartersawn
tongue in groove, white oak.
A bigger job than I thought.
But boy, do the lookylou's like it!!

So far I have done quarersawn white oak over plywood and red oak
parquet over plywood on another boat.
I did the parquet red oak because I was stupid and it was cheap at
Home Depot.
It will work after saturating it with 5 gallons of penitration epoxy
and then coating the deck with $300 worth of
two part marine epoxy.
Yes...I know, really stupid. But I am sharing this in case another
boat lover is thinking about taking that ratty carpet out
of the boat they are restoring and putting a nice deck over the
plywood.
I was told that bamboo flooring wouldn't work, because you can't glue
it down. Bamboo shrinks and expands so much that a floor
has to be floated.
I am a wooden boat guy, and I believe that carpet in a wooden boat
causes mildew, and rot. It stops air circulation and gets
heavier and heavier over time.
Does anyone know what the best carpet for boat interior or exterior
that can be snapped in, and doesn't mildew?
