Re: Burgundy

I agree I did boat repair for a number of years and have seen many
many delaminating rotting boats where door skin was used. This was
from the 70's to now. Even luan plywood is suspect as shown by all the
cheoy lees with new decks.

I don't think this is what the wiki page says at all. Here's what it
actually says:

This does not mean that each of these is a different species! What it
means is that any and/or all of the species in the Shorea group might
be referred to as Meranti, Lauan (or Luan), Seraya, Balau or Bangkirai
at one time or another.

Lauan is actually a Philippine word that has always been used in a
generic sense for a number of different Meranti species that grow wild
in Philippines and other Southeast Asian countries. This wood used to
be harvested in huge volume here until sources were depleted to such an
extent that most of the Lauan sold in the USA these days now comes from
Indonesia.

Yes it is ... but the quality of the MANUFACTURING of those door skins
and underlayment may not be as good as some people might like for their
boats, and manufacturing quality varies from one company to another,
and even from one day to the next.

Indonesian factories make this plywood as cheaply as possible, then they
export it to countries like the USA where it is marketed as door skins
and subflooring. Of course this is the cheapest stuff they can produce
for their foreign buyers, and it is perfectly fine for underlayment and
door skins -- which is to be expected since these are the specific uses
for which it is manufactured.

But even though it is made of relatively high quality raw material, the
manufacturing process itself might be inferior in terms of producing a
good boat building product. Some factories skimp on the glues, which
even if WBP rated may be applied so thinly that the layers delaminate.
And in door skins the glues are more than likely not waterproof anyways
since door skins are used primarily to manufacture interior doors. I'm
always surprised to learn that Americans are using door skins in their
boats, but maybe some door skins actually use waterproof glues ... ?

Better quality Meranti/Lauan plywood comes not from factories in
Southeast Asia but from factories in Europe. The European factories
send their raw material buyers directly to the countries where Meranti
grows wild in the forests. These buyers hand pick every tree they will
purchase, then the local suppliers cut and debark the trees and ship
them in containers to the buyer's factories in Europe where high
quality Meranti marine plywood is manufactured. A small portion of
this plywood is eventually exported to handful of high quality plywood
retailers in the USA who ship and sell it nationwide.

If you want the best quality Lauan/Meranti you will "pay the price" for
European manufacturing, and you will get what you pay for -- the best
hand selected materials and high quality manufacturing. But if you're
willing to settle for the cheaper stuff which is is nearly always made
specifically for export in Southeast Asian plywood factories (and not
designed for boat building or even for local use) you can buy as much
as you want in your local Home Depot for a very low price. Just don't
expect the cheap stuff to be ideal for boat building, and be happy when
you find some that is ... :)


> With thousands of Shorea you can count of a
> promiscuous use of any recognized names.

Yes this is very true, especially when using the term "Lauan" since
Lauan has always included a variety of different species. There is no
question that when local Filipinos use the term "Lauan" they are
referring to a number of different species as a group, or to an
individual specie which occurswithin this group. It is only after you
ask them which specific type of Lauan they are referring to that they
will identify a particular specie for you.

If it is called Lauan by a Filipino it is generally a good boat building
material for hulls and stringers and frames and such. But they still
use different woods for bowstems, keels, and other areas ...

One of my paddle boats uses a variety of Mangrove in its bowstem. This
wood will never rot or be eaten by insects or so-called "shipworms" and
it is hard and sturdy, but not lightweight by any stretch of the
imagination. My Tolman Seabright Skiff uses another very hard, stiff
and inflexible specie for the core of its composite rudder shaft, and
this wood is also impervious to rot and insect attack.

Each wood has its own specific properties, and a good boat might be made
with a half dozen different species.

Perhaps what's really needed is for you to read your own link.
Meranti and Luan are two completely different species only thing
that's similiar is they come from the same forests. Something like
Maple and Oak, live in the same forests but are most certainly not
the same wood.

As may be, but is this "real" luan the stuff in doreskins and
subfloring being sold over here, that's the "luan" mostly under
discusion in the US boatbuilding circles, not whatever is fashionable
in the phillipines. With thousands of Shorea you can count of a

There is a high grade meranti 1088 ply over here, and it is darker
and heavier by a significan't margin than some of the other species.
Luan runs about 2.6 pounds a bft (ply) a softwood like weight. I'm
not sure what the 1088 meranti runs, but 11 1/2" sheets of the stuff
added 500 pounds to the weight budget of a friend's boat when he
couldn't get Okume (probably another meranti/shorea species). So I
am guessing it could be 50 or more percent heavier, at least.

Also the same species means nothing if it is a differnet grade. Old
growth black spruce is listed as having similar qualities to sitka
spruce, but I wouldn't count on it in black spruce 2x lumber, as nice
as it is for houses. I don't think they make classical guitar
soundboards out of the fast commecial grown redwood fence stock.

There is a widely planted meranti that is the fast growth weed
species of the Phillipines also. I'm not going to lay a keel with it
on my next repro of the Bluenose.

I don't know what to think of this comment ... ?

Real "Lauan" is Meranti, a very rot resistant wood compared with most of
the other wood species used in backyard boat building in the USA these
days.

In the Philippines Meranti is the most sought after general purpose boat
building material specifically because it doesn't rot anywhere near as
much as many of the other available wood species here.

It used to be the case, and reagionally occasionally still is, that
luan DSs were phenolic glued. These days that is rarely the case, a
lot of builders who pioneered doorskin constructions in DD, CC, and CM
no longer have a material for their designs in most areas.
Substituting the 1088 stuff is expensive and sorta undermines the "I
broke the bank at Montecarlo" feel of building out of stuff that cost
about 8 cents a square foot for finest wood veneer.

I have built a few boats using the newer DSs and it isn't quite the
suicide pack one might imagine, but even at it's best luan will rot
out long before any other wood it comes in contact with.
Thanks for posting this Bruce.

Yeah, funny thing. You can find unloved old plastic sailboats from
the '70's, literally for free. And, they might have $3,000+ in
salvageable parts.
For some reason, I know of it as "One Man Live-a-board Concept"

I did a paper model a while back...

Pretty sure it is in SBJ #42, Apr/May 1985

If you're in N. Cali, I have a friend of a friend who scraps old boats for
walking around money. If you're in the market for lead for keels, I could
probably connect you directly with him and cut out the middleman. The
difference between what scrap dealers are paying for scrap lead and what
they're selling it for is a factor of 2-3 in that area. If I was building
something like a Burgundy, that's how I'd do it.

The only reason would be if you had a source of good cheap boat
lumber. Where I live, we do not. So if I were to build a Burgundy, I
would use fiberglassed plywood too.

> The side panels will require some serious man power to wrestle around

Those panels would be similar with the side panels of my Topaz, which
I installed single handed, with the help of a farm jack, string and
drywall screws. Both boat's side panels are 250 lbs., 30 ft long and
floppy. I built them oriented in the right direction so you can drag
them into position. Then, you lift and move them a little at a time
until you got them where you want them.

The hurt with a Burgundy is the price of scrap lead now-a-days.
I agree with your statement Clyde. No reason not to build with
plywood. You would gain in speed of construction. The issue would be
value, and durability of the finished boat with the nagging question
of plywood quality. The builder would gain both by building as Bolger
suggests in "30 ODD BOATS" the Burgundy essay. The side panels can be
created flat, mirror image, laid on top of each other, and trimmed to
final identical dimensions, just like the plywood. Burgundy is big.
The side panels will require some serious man power to wrestle around
the expansive work area. Still, in a mild climate, it could be done
outdoors.

IMO this speculation about materials of construction for Burgundy
starts me thinking about the classic inboard engined runabouts that
are cold molded, as shown on the Glen-L website. In the essays about
those boats, they mention "creating your own plywood" in place as the
boat is built. Those boats are built from multiple layers of luan
door skins cut to easily handled strips and laid on a mold bedded in
epoxy.

Perhaps selecting the plywood design you wish to build and then laying
out the panels flat on the garage floor, and gluing them up with epoxy
using larger strips of luan door skins for speed of construction will
create the strong, durable, beautiful, and valuable boats most all
would like to own.

Bruce,

I've a;ways admired Burgandy as a frasible alternative to Rozinante. As far as I know, no one has ever built one--perhaps because of Burgandy's unusual construction.

If you get bored, I would love to see isometrics for PCB's plywood canoe yawl, Liveabord for one, and the plywood motorsailor which appeared in the last real issue of Small Boat Journal.

would be a super simple, easy and elegant day sailor.
I can see no reason not to, however I am lucky enough to live in an area
where high quality lumber is still available. If I was going to build
the Burgundy I would do it in Yelllow or Red cedar and finish it clear.
It would be gorgeous.
