[bolger] Re: Lauan vs. AC vs. BC
Lauan appears to be the material of choice for a number of builders in NS.
Its main advantage over AC/BC is supposedly the guaranteed absence of voids
(potential law suits from spike heels breaking through floor layers).
Several windsprints and possibly LS's that compete in the Mahone Bay WB
Festival are made of lauan. As far as I know they've been around for years.
They do appear to be somewhat prone to surface checking and I've heard some
concerns re. delamination.

ok, if you are going to hang onto your boat and make it into a
strawberry planter when you are done with it, AC will do. If you think
someone else is going to buy it, then be carefull and don't expect too
much. You will lose money on the deal, I promise.
I have built the following with the following results:
Cape Cod Frosty - luan/bondo : boat sank at finish line
Cape Cod Frosty #2 - luan / WEST : boat rotted after 4 years of
storage on bare ground
Diablo - 1/2 in luan, 1/2" transom rotted, 1/2" floor rotted, 1/4" AC
Exterior sides ok
Diablo (rebuild) - all AC, coated with epoxy and glass, fine after 6
years.
Pointy Skiff - 1/4 luan is delaminating after 12 years of hard work.
Will rebuild with ac/glass/frozen snot. Great Boat!
Nymph - 1/4" AC exterior. wonderful, still going!

Hi,
Payson reccommends AC plywood in his book The New Instant Boats. He makes
the argument that the minimum standards for manufacturing marine plywood are
now about the same as the specs for AC, and that they use the same glue to
make both.
(He is talking about the allowable void content)
I am building a Carnell sailboat using AC. I did not candle the wood, but
hardly any voids show up when I cut the pieces out. It cost me $14.50 per
sheet here in landlocked New Mexico. The nearest source for marine wood Is
Houston, Tx. They want $46.00 a sheet. The freight would probably add
$100. to that. My boat will not live in the water, and will be stored
inside when not in use. I don't anticipate any problems with the AC.
Lets see... $58.00 for AC, $284.00 for marine.
Carnell is going to have to change that from a $200. boat to a $500. boat!

I just wanted to stay cheap, but durable. I guess I'll just hunt down some
good AC or BC pine and an old Jonboat trailer. Or build a smaller boat.

Good exterior grade lauan is fine for small, trailed, car topped or
pickup trucked boats that are taken care of. Store the boat upside down
outside, or better yet, inside.
If you plan on leaving your boat in the water, or not keeping it dry
between uses, you should probably use marine grade plywood.
If you are concerned with resale value, you should probably not be
building a plywood boat...

Wow! slow down. I have had some nasty experiences with exterior grade
Luan. If the interior core gets wet, then it is almost impossible to
hold it together regardless of what glue has been used. I have used AC
with good success, but the time spent in finish work loses whatever
money you saved. there is also a problem at resale time. You will be
hard pressed to find a buyer (who knows ply) that will buy a boat of
non-marine grade plywood. Marine grade plywood is for boats! The
other stuff is for subflooring and such which is not constantly damp.

Yes. Have built three out of it.
Other than the very thin surface veneer, the major drawback is quality.
One HD in Tulsa had nice exterior glue lauan that worked very good. They
ran out, so I went to the other HD to get some. This batch started
delaminating before I could even get it in the boat!
So, be very picky, and you should be fine.
Be sure it is "exterior glue" lauan, do a boil test on a sample.
It will have some voids, you can candle them if that will be a problem.
Bet sure it's good quality and has good faces, before you buy it.

Built my Gypsy out of quarter inch luan with a 6oz. fiberglass covering.

Luan is OK if it passes visual inspection for voids, knots, etc., is
labelled "Exterior", and cheap enough to buy a sheet and boil/freeze a
sample. I'd say at least six years for semi-careful storage.

I checked the archives on this, there isn't much about lauan.
It seems to be much lighter than the BC pine that I've seen- what are the
compromises? I'd like to build a cartoppable boat, and the lauan seems to
help in the weight arena. I just don't want this thing to come apart after
six months.
Anyone out there built a boat from 1/4" lauan? What were your experiences?
