C2 Owner's Manual 4
Introduction
Congratulations on purchasing your new GOODALL C2. The C2 is the direct result of 7 years research
and development. During that time we developed and learned from the CAPRICORN platform and now
we have combined that knowledge with state of the art manufacturing techniques to bring you the
highest quality and performance possible.

About this Owner’s Manual
This manual has been compiled to help you set up and operate your C2 catamaran safely and easily. It
contains details of the boat and its fitted equipment. Please read it carefully and familiarize yourself with
it and the boat before rigging and sailing.
You have purchased a high performance racing catamaran and as such you should ensure that you are
able to handle the catamaran in the anticipated wind and sea conditions. This owner’s manual is not an
instructional on boating safety or seamanship. If this is your first beach catamaran, or if your unfamiliar
with it, please ensure you obtain handling experience before “assuming command” of the boat. Your
Dealer, National Sailing Federation or Yacht Club will be pleased to advise you of local sailing schools, or
competent instructors. Buoyancy aids are required for all racing events and are recommended to wear
at all times by all crew.
In some countries, a driving license or authorization may be required, or specific regulations might
apply. Please familiarize yourself with these.
This craft has been classified (in Australia) as a category C vessel, meaning a boat designed to operate in
winds up to Beaufort force 6 scale and associated wave heights.
Always maintain your boat properly and make allowance for the deterioration that will occur in time and
as a result of use. Any boat, however strong it may be, can be severely damaged if not used properly.
Please read this manual and familiarize yourself with all aspects of maintenance and care for your boat.
Please keep this owner’s manual in a safe place and hand it over to the new owner when you sell the
boat.

heights (significant waves up to 2 meters) Such conditions may be encountered on exposed inland water, in
estuaries and in coastal waters in moderate weather conditions.
A significant wave height is the mean height of the highest one third of the wave, which approximately
corresponds to the wave height estimated by an experienced observer. Some waves will be double this height.”

DANGER FROM OVERHEAD POWER LINES AND OTHER OBSTACLES
When rigging and moving your boat, please look up and inspect
the overhead area. Observe the location of overhead power lines
and trees. These obstacles can damage your boat and are
potentially dangerous or deadly to yourselves.
TOWING ON THE WATER
When towing is required, ensure that:
-The tow rope is secured around the mast step or main beam.
-The boat is towed at a low speed.
-The tow line is fastened in such a way that it can be released quickly when under load.
-The tow line is to be of sufficient length to maneuver safely.

C2 Owner's Manual 7
Assembly
All GOODALL boats require minimal assembly; all parts are rigged in the factory and come almost fully
assembled so that you can be on the water as soon as possible.
Should your boat have come through a local dealer, most of the assembly has probably already been
done for you, but take this manual as a reference for building up and dismantling your C2 when
transporting and storing.

C2 Owner's Manual 9
1. Place the 2 cardboard boxes that contain the
hulls parallel on a flat surface approximately
2 meters apart and carefully cut the top open.
The sides of the boxes may be folded down
to provide a clean and protective working
surface. The packing frames inside the box
should keep the hulls upright while you work.
2. The beams will come from the factory pre-
rigged and ready to go onto the boat. The
shorter bolts and smaller washers are for the
outer locations and the longer bolts and
bigger washers for the inner locations. To
access the outer bolt holes you will have to
remove the plastic end caps from the beams
with a Phillips head screwdriver, don’t undo
any of the shock cords on the front beam as
they are already in the correct position.
3. Wipe all dirt and grease from the beam pad
before sitting the beam on. Make sure the
beams are facing the correct way. The rear
beam should have the traveler saddles facing
backwards. Apply grease to the threaded part
of all bolts before inserting them into the hull.
Get all the bolts started before tightening any
of the bolts. We recommend beginning with
the inner front beam bolt. If a particular bolt
is being difficult to fit. Release all the beam
bolts and fit this bolt first.
4. Use a 17 mm hexagonal socket or spanner to tighten the bolts properly. The bolts should be set to
20Nm using a torque wrench. Check the bolts regularly but in never exceed the recommended 20
Nm.

C2 Owner's Manual 10
5. To reduce the risk of any sharp edges inside
the hull tracks cutting the tramp, use a small
piece of rod wrapped in sand paper (120 grit
or less) and slide the length of the track and
back to sand the inside edge of it.
6. To fit the trampoline to the main beam, remove the end plate from the front beam and slide the
trampoline into the front beam groove refitting the end plate once the tramp is in place.
7. Loosen all beam bolts 2 turns; fully remove the beam bolts from one end of the front beam and
allow the bows to move closer together.
8. Insert the bolt ropes on either side into the
track of the hull. Carefully slide the
trampoline down the track on each hull. This
is best done with 1 person on either side of
the platform keeping it even on each side. It
is recommended you have someone feed the
tramp into the track while another person
pulls the tramp on.
