rugged workboat style vee hull, simple to build and economical to operate.

hull weight shown in the table includes the console, empty fuel tank
and basic rigging but not the engine.
builders love our Outboards Dories, OD16 and OD18 because
they are simple, economical and easy to build seaworthy boats.
Many asked for boats with the same qualities but with a vee-hull.
We designed a set of rugged, simple to build work boats with a vee-hull
based on a proven work boat type, the Panga.
Mexico, the word "panga" applies to any small boat but mostly to beach
launched skiffs between 18 and 26' long. The pangas have a narrow beam
and high bow. They are powered by relatively small outboards
type of boat is also very common in Africa and in Asia, in particular
Indonesia and the Philippines. The most beautiful example of the type
is the famous Saintoise, very seaworthy work boats some as long as 35'.
those boats evolved from the same hull shape: fishing boats designs
from the FAO for third world countries.
In the FAO project, the accent was on ease of building and economical
operation. Max. HP rating was 10. Because of their hull rocker, the
FAO boats were limited to displacement speeds.
Builders modified these plans to allow the boats to plane with larger
outboards but kept the original narrow beam, fine entry and high bow.
The result are fishing boats of moderate speed designed to hold heavy
loads while maintaining fuel efficiency.
design is based on that hull type. It includes the straight run needed
to get on plane.
Like other Pangas, our boats are strong but simple to build and economical
20 footer is a very able but small boat for it's length.
The cockpit is self-bailing up to a displacement of 2,000 lbs. at level
Like her bigger sisters, she can be made completely unsinkable with
the addition of expandable foam under the sole and under the gunwales.
Each two gallon kit of foam provides on the average 500 lbs. of flotation.
Considering that the hull material has positive buoyancy, we recommend
3 kits for a total of 6 gallons.
We recommend a 50 HP outboard. With this engine, the PG20 fully loaded
will cruise at 25 mph and have a top speed between 28 and 30 mph.
are designed as work boats, not speed boats and while the PG20 can accept
engines as large as 115 HP, we do not recommend to install anything
larger than 70 HP.
DWL displacement and WOT, a 50 HP will give 29 mph and a 70 will go
at 35 mph. The minimum HP required to plane at designed displacement
of 1,650 lbs is 30.
interior is clean and simple with a lot of room. With all the open space
it can easily accommodate a family for a day on the water.
builder is given complete freedom in the layout of the boat. As long as
the frames shown on the plans are present and common sense is used in
weight distribution, almost anything is possible: simple open plan with
a center console, thwarts, longitudinal benches, small or large casting
plans show an 18 gallon fuel tank under the casting deck. With the recommended
engine, this will provide sufficient range for a full day on the water
but if necessary, larger tanks can be installed.
to our flat bottom OD boats, the Pangas with their vee hulls will require
a little bit more skill and more labor to build but not much.
Because of their narrow beam, their performance and behavior can not be
compared to other vee hulls of the same overall length except for seaworthiness.
In the hands of an experienced skipper, they can venture far offshore
and take bad weather but they will not offer as much room or speed as
a wider boat of the same length.
The boat is built in stitch and glue fashion but is a true composite
sandwich. The plywood is a core sandwiched between layers of directional
glass and it is the fiberglass that supplies most of the strength, not
in our other boats, the frames and decks are part of the structure.
Pangas should be built the traditional way upside down on a jig made of
the frames. This guarantees a nice straight bottom without hook or rocker.
That building method is described in all books about boat building but
also in our HowTo file
at our technical support web site, bateau2.com.
careful builder could assemble the hull without a jig using the folding
panel technique but he must pay special attention to symmetry and bottom
all our stitch and glue boats, the Pangas are easier to build than plywood
on frame or most other stitch and glue boats.
long boat is easier to build because there is less curvature in the panels
and this gives an extra advantage to the Pangas.
We worked hard to keep the building as simple as possible: many of the
plywood cuts are straight lines, including for the hull panels. The nice
curves are created by well planned bending around the frames.
drawing above shows one of the two side panels on 3 sheets of plywood.
Note that the long side is aligned with the plywood panel: no cut. The
other sides are all straight lines: easy to measure, easy to cut.
All the plywood parts have been precisely calculated: you cut them flat
on the floor, no need for templates, no need to take measurements from
the hull framing as in the plywood on frame method.
plans show a basic layout with dimensions for a standard center console.
The center console is easy to modify if the builder wants to make it taller
fish boxes, cooler and storage benches can be added almost anywhere.
The casting deck can extend
further back and the console can be moved back a little bit. We take in
account that most builders will have batteries in the stern and compensated
by putting the console further towards the boat than usual.
The plans include a typical drawing showing how to cut lids in seats or
in the casting deck.
PG20 can also be rigged with tiller steering but this reduces the max.
recommended HP to 40 HP.
Do not install excessively large engines: top speed increase will not
be significant because this hull is designed for moderate planing speeds.
Our designs are consistently faster than fiberglass production boats of
the same type and size thanks to the lighter, stiffer hulls and careful
design. A larger engine will weigh more, result in poor trim and use more

BOM list materials based on our standard layout and includes a 15% waste
factor for fiberglass. For plywood, we use standard sheets 4' x 8' (122
x 244 cm). Please read the building notes and see the plans for detailed
specifications. Marine plywood is specified for the hull. Meranti marine
BS6566 cost less than Fir marine and is far superior. See our online plywood
store: $26.00 a sheet (1/4").
Okume and Meranti BS1088 are even better. Good quality exterior is acceptable
if it has no voids.
