I was wondering abotu using salt-treated plywood on the Marquis deck.
I'm not a feared of paying for marine grade, but Jimmy the carpenter
told me that the newer salt treated woods are about as worthy as
marine grade at a fraction of the cost. So, what's the opinion?

I'm even wondering abotu using hybrid decking like you'd use on a
porch. synthetic mylar etc mixed with wood. The stuff is weather
resistant as all get out!

Tim,
I like exterior fir plywood. Marine ply is the same wood and glue but more
layers and a solid core. Fir stands up to wet environments, unlike pine and
the glue is waterproof.
Exterior fir was 1/2 the price last time I did bought any. maybe 2 years
ago.

I think a lot depends on how long you expect to keep the boat, and how
much value you put on your time and effort. There's no question that
the marine grade is more durable over the long term and it has fewer
voids.

Check the weight. The artificial decking that we have on our dock is
quite heavy.

Does the composite stuff come in sheets, or were you going to use boards, like

I'm thinking of resurfacing my deck with that stuff. Expensive stuff though.

The beach house we have access to in Hilton Head has that on the
walkway to the dunes and on the deck that sits on the dunes at the
beach. It's at least 15 years old, and still looks great.

Only problem is that they have sagged in places between the joists
holding them up, worse than a wooden board would have in the same
situation. They seem to need a little more support? Might be worth
talking to a local professional about that.

I looked at everything when I decked my pontoon boat 20 years ago. We
had a Wolman plant here at the time and they offered to pressure treat
any plywood I would bring them but the guy who ran the plant said PT
really only protects it from bugs. If water is your issue, save your
money. I ended up with MDO plywood (one side) and it is still going
strong after 20 years in salt water. That is basically 7 layer
exterior grade plywood with one MDF layer. You would probably have the
same luck with BC
The main thing is to be sure everything is sealed before you put it in
and seal all penetrations. The only bad spot I have found in my
current rehab is from an unsealed penetration.
Cut all of your pieces to size, paint them on all 6 sides with 2
coats then install them. Paint it again to cover the screws. Bristol
Palin will be running for president before that plywood goes bad.

Yeah, but will it last for her eight years in office?

I worked on a sailboat once that had a PT plywood sole and where it met, the
aluminium mast was badly pitted.
I thought it may have been caused by the cyanic acid?

John, this is the crap we used on our front porch. It faces the west
and gets all the harsh summer sun and the rain etc. We redid our porch
twice with treated tongue and groove pine and it was rotting in 5
years. Enough was enough. This stuff is extremely durable, looks and
feels and acts like wood. We've been satisfied for 10 years now.

So I was thinking of using this stuff decking the boat from side to
side instead of long ways from bow to stern.


Just a thought, though.

Tim a real good grade of plywood will work fine just give it a coat or 2 of
epoxy resin to seal it, regardless of what you use and by all means if you
go with treated use only stainless steel fasteners or the new treated wood
will eat the fasteners in short order.

I think you can use acetone to thin your first coat of epoxy so it will
penatrate well. I'm sure thers info on this subject at Iboats
