You might try talking with the fishermen in the area since they have long
experience of what shapes work and which ones don't work well for their
waters. Then work from there.

I agree. I see the boats they use, and they look very seaworthy in
shape and design.

And after all they are the one that are going to use them. It will be
easier to persuade them to use the boats, and their lives are the ones
at stake.

Proposal is for new techniques. Fishermen may not imbibe new ways of
boat construction without training.

They are handed down from experienced masters or just duplicate
existing shapes. As marine technology has developed so much, expect
that standard/recommended design methodology or practice has become
available,one can start from an instruction manual.

The Pangas are derived from some free FAO designs;
http://www.fao.org/documents/show_cd...E/W7260E00.htm
Those FAO boats are cheap to build and operate but don't plane. If you
sligthly modify the FAO boats by making the aft part of the bottom
straight, they plane with larger engines. The similitude between them
and "pangas" is striking. Those modified FAO boats are also common in
Asia, Indonesia, Philippines etc. It looks like they all derived from
the same set of plans.
There are also Panga plans for amateurs at our web site:
http://boatplans-online.com
Per could even build them from 3D honeycomb, we sell that stuff under
the name Nidacore ;-)
but they would be too light and it would go against the program of the
boat: eays to build and maintain with locally available materials and
skills.

To the original poster, I would say, get the free FAO plans from the
link above.

Hi

"but they would be too light and it would go against the program of the

This is proberly the core issue but please remember how skilled
craftmanship you se from these contries, --- My attitude is ofcaurse
that to further gain and make a relevant promise of a future that work
, these skills shuld be put into digital rather than staying with
methods and tools that was relevant 70 years ago. Now please exchouse
I repeat but 3D-Honeycomb form any shape, it even prove easyer presing
a button to get the intire framework assembly, than adding rib after
rib polyline or spline , translate this into somthing that in it's
aproach is the same Oak rib as you seen in ships from the 17' century
---- it even is easy for the designer, the one who shuld draw eash
frame stringer and rib, to have the computer calculate everything down
millimeter accurancy and in only one material sheet material , as this
also make the same easy foundations for a house --- now do you read me
?
