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:

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.

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.
