It will be cheaper for them if they can eliminate the dugout canoe and will
save them time to build the boat. I asked some boat makers in the south of
manila that their waiting time for the dugout canoe is about four to five
months. The price is not cheap for a very crude work that they still have to
finish. It is the most expensive part of the boat and mostly came from
illegal cutting.
You can see from the link I provided earlier that the price of the boat can
go up to 3000 dollars which is not affordable for many native filipinos.

Any advise or comment if I will use polyester and fiber glass on top of
cured and sanded epoxy on stich and glue? My plan is to prime the entire
hull with epoxy for a good bind before the application of
fiberglass/polyester skin.

I want to introduce this idea to the poor fishermen in the Philippines
for
economic reason.

Polyester does not bond very well to epoxy. Most authorities advise
not to use this method.

The "old" system was to use thin polyester resin to impregnate the
wood. Then use polyester resin to "glue" it together. Many boats were
built this way in the early days of "fiberglass" construction.

I think I'd question your idea. Why not just use waterproof plywood to
build boats? It has been done successfully for years now and I would
guess that the Filipinos are well aware of how to build boats.

They are still using the old practice of cutting trees to make a dug out
canoe for the bottom hull with extented sides made of plywood. The dug out
canoes are being sold to the local fishermen by those illegal tree
cutters.
I like to introduce the stick and glue to eliminate the dug out canoe
which
will be cheaper for them and will save the trees. This is the native Banca
using outriggers on both sides.

Will it really be cheaper? I ask as in Thailand a bunch of guys came
over to show the natives how to build boats and the fishermen didn't
buy it. The local built boats were cheaper and longer lasting.

you ever wonder why those boat makers are still waiting for those
dugouts?

they have a ton of programs to teach them modern boat building and
they dont use them.

the natives dont like the stich and glue boats. the boats dont behave
the way those dugouts behave and they look funny. all that framing
inside getting in the way.

have you spoken to the poor and found what they want in a boat?
my guess is that they will still not be able to afford your stich and
glue monstrosity mostly because they cant take a chance on if it will
work or not.

dont spend time talking to those with cash that wont actually use the
boat talk to the folks who will be depending on the boat to not
starve. the you will get some answers as to why those boat builders
are sitting around drinking wine and waiting for the illeagle logs to
be cut.
