MDO plywood has been used for at least 30 to 40 years by the boat
building industry. Skiff Craft "http://www.skiffcraft.com/"uses MDO
for all of its planking. I used to live very near by an have visited
the factory many times. About 10 years ago I owned a 1960s vintage 18
foot runabout built by them that was built out of MDO on steam bent
oak frames. It was in very good condition after that many years of
use. I just recently used 1/2 inch MDO for my AF3 bottom. I am sure
that it will be the longest lasting part of that boat.

. My only question is how LONG will it hold up?
it is probably one of the finest micros out there.

MDO is a plywood product that is an excellent substitute for marine grade
when chosen carefully. MDF is a fiber board product which would be a huge
mistake to use anywhere around water. Medium Density Overlay is often used
for highway signs and there is a product level that is suitable for
boatbuilding. Medium Density Fiber board would not be suitable. The
overlay used on MDO is very compatible with epoxy and has the advantage over
fir plywood that no grain or patches will show through paint.

Hi Barry,
I'm no boatbuilding expert. Have been working on my first "instant
boat" type sailing dinghy since last fall. Building out of 6mm
occoume. However, I own an architectural millwork firm, and have used
MDO (medium density overlay) numerous times for exterior (signage,
etc.) applications. It was recommended to me both by several
suppliers, and by the sign company that makes all of the freeway
signage hereabouts ("Exit 269", etc.). I would not regard it as a
chipboard/melamine substitute. Perhaps you're thinking of MDF (medium
density fiberboard). This is a lot like chipboard, but made with much
finer fibers and better grade resins. Some if it is even billed as
"waterproof" but I wouldn't want to test it by building a boat from
it. The MDO panels we've used have been very tightly laid up fir
plywood cores with a final facing on both sides of resin impregnated
paper. Smooth and waterproof. Good for painting. Hold up outdoors. I
see lots of posts where it is being used for boatbuilding with
apparent success so far. My only question is how LONG will it hold up?
My suspicion is that it will hold up as long or longer than my marine
grade occoume, but I'm not sure it's actually been in use long enough
to know for sure. Anyone out there built an MDO boat 10 years ago? 15?
20? How's it holding up? Inquiring minds want to know.
Cheers,
David Graybeal

Dear List,
I was following the discussion about the Marine Ply and someone mentioned
MDO, which I am familiar with, MDO stands for Medium Density Overlay. I
want to make sure I understand. MDO is a chipboard/melamine substitute. Is
it really suitable for boatbuilding? (waterproof/strength/epoxy glueable
etc). Could you please clarify?Thanks
