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.

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.

Platform
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.
C2 Owner's Manual 11
9. Refit the beam bolts that were removed in
step 7. You will require a 2nd person to push
the bows apart to achieve this. Then tighten
the remaining bolts to 20 N/m.
10. Slide the alloy tube into the pocket at the rear
end. Use the 3mm cord to lace the tramp to
the rope buttons on the rear beam as per the
picture. By starting at one side, tighten the
lacing as much as possible and tie at the
other end.
All cords and bungees will be pre-fitted at the
factory. Refer to the systems section of this
document for diagrams.
11. After the platform has been assembled, the
dolphin striker will need to be tensioned. Use
a 24mm spanner to extend the striker post
between the front beam and the striker strap.
The front beam should bow up in the centre
(10mm).
C2 Owner's Manual 12
12. Toe straps have been provided on the
trampoline. Tie the toe straps to the saddles
on the rear beam and tighten to preference.
13. Remove the bottom half of the Stamasters
from the side stays and attach to the side
chain plates with the locknut on the inside
and the control line loop facing forward.
14. The Continuous Cunningham system will be setup from the factory, refer to the Systems section for
a diagram.
15. Thread the mast rotation (yellow) through the tramp eye and cleat, then around the side stay.
Use the spare skippers trapeze shock cord to take up the slack.
C2 Owner's Manual 13
Mast
Your mast should already be fully assembled if purchased from a Goodall Design Dealer. If the mast has been
shipped directly to you, there is a small amount of assembly required.
If not already fitted, fit the spreader to their
respective brackets and secure the locknuts
using a 7mm spanner.
Pass both diamond wires through the slots
in the mast and wind them into the black
adjuster nut. Make sure the lock nuts are
used.
Connect thread the adjuster bolt onto the
adjuster nut with the mast base in place.
Turn about ten turns onto the bolt and push
the base into position
Connect the diamond wires to the top
diamond tangs. Make sure the lock pin is in
place and cannot fall out
C2 Owner's Manual 14
To fit the diamond wires, the mast should
lie flat on the ground. Clip the diamond arm
end cap onto the wire and put your feet at
one side of the mast at either side of the
spreader. Pull the diamond wire until it the
cap slides into the spreader. Secure it with
the screw provided. Repeat this on the
other side. You will notice this takes
considerably more strength. Make sure the
spreaders are perpendicular to the face of
the mast and set the diamond tension (in
accordance with the tuning guide) with the
17mm bolt at the bottom of the mast base.
To prevent the spreader being knocked out
of alignment during capsize, wrap some
high quality tape around the wire and arm.
Maintain this as it can decay over time.
If the arms are out of alignment this can
case the arm to collapse and the mast to
break.
Check that the mast is straight in the sideways direction by sighting down the sail track. If the mast
has a bend this means that one diamond wire is tighter than the other and they need to be made
even. Determine which wire needs to be tightened and releasing it from the diamond arm and the
tang towards the top of the mast. Twist the whole wire clock wise while looking from the top of the
mast; this will turn the small threaded swage inside the mast base and shorten the wire. Refit the wire
to the tang and diamond arm and check for straightness. Repeat if necessary.
C2 Owner's Manual 15
Rigging
All rigging is fully assembled at the factory; it will simply need to be attached to the mast. The
trapeze wires attach to the upper hole on the hound fitting. The side and forestay attach to the
larger lower hole.
Spinnaker pole
Attach the spinnaker chute to the pole with the Velcro straps on the chute.
Now your Boat is ready to rig!!
C2 Owner's Manual 16
Rigging
Raising / Lowering the Mast
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.
Before raising the mast you should organize your Spinnaker halyard, see next.
The usual procedure is to raise the mast from the back of the boat, however the hinged mast step allows
the mast to be raised and lowered from any direction. The key to this is that the front of the mast must
face the direction that it is to be raised from, or lowered to.
Raising the mast requires a minimum of 2 people. The usual procedure would be:
1. Put the assembled platform on a flat surface, preferably with its sterns windward.
2. Position the mast on the boat, sail track down, with the top of the mast out the stern.
3. Connect the side stays and for stays to the
lower hole on the hound fitting ensuring that
the forestay is in the center. Connect the
Trapeze wires to the upper hole on the hound
fitting.
4. Connect the side stays to the corresponding chain plates, with the Stamaster adjusters at
maximum length.
5. Untangle and connect the skippers’ trapeze wire to the shock cord on the deck. The skippers’
C2 Owner's Manual 17
Trapeze will be the outer most on the shackle at the hound.
6. Turn the mast over, sail track up, and connect the
base of the mast to the mast step using the hinge
pin.
7. Walk the mast up from the stern, you will need to step onto the trap or pass the mast to a 3rd
person already on the deck to complete this. At the same time the 2nd person should be pulling
the mast up using one of the trapeze wires.
8. When the mast is vertical allow the mast to rotate so that sail groove now faces backwards. DO
NOT let the mast rotate until it is vertical.
C2 Owner's Manual 18
9. Hold the mast upright with one of the trapeze
wires while bridle is connected to the
chainplate. Connect the bridal to the front
chainplates. Ensure the bridal wire with the jib
downhaul (Dyneema) is attached to the
starboard chainplate (bellow). Wrap tape
around the split pins to ensure spinnaker dose
not catch and tear.
10. Set the fore stay to the appropriate hole on the bridle tube for the required mast rake, as per the
tuning guide.
11. Adjust the Stamasters to tighten the rig as per the tuning guide.
12. Take out the hinge pin from the mast step. This must be removed when sailing to avoid
damage.
13. Connect the crew trapeze wires to their shock cords.
Lowering the mast is basically the reverse as raising it (also requiring 2 people):
1. Detach the boom and spinnaker pole.
2. Put the pin back into the mast step hinge. IMPORTANT!!!
3. Loosen the tension on the side stays.
4. Undo at least on trapeze wire.
5. Use that trapeze wire to pull the mast forward, releasing the pin holding the bridle to
the chianplate.
6. Turn the mast around so that the front of the mast is facing the aft direction
7. Gently ease the trapeze wire while the 2nd person stands on the trampoline and lowers
the mast down. Be careful not to drop the mast on the track of the rear beam.
8. Remove the hinge pin and turn the mast over
C2 Owner's Manual 19
9. Undo the remaining trapeze wires and take the Stamasters apart.
Spinnaker Pole
Setting up the spinnaker pole is done after the mast has been raised.
1. Fit the spinnaker pole to the front beam
using the pin and retainer clip. The pole
must be supported by the bridle loop
while this is done.
2. Assure that the knots on both bow braces are the same length. Connect the front braces to the
bow by passing a loop through the hole in the bow and then pass the knotted tail through the
loop on the outside to prevent the loop coming back through. Work this firm so it will not move
during sailing.
C2 Owner's Manual 20
3. Adjust the bridle loop so that there is a
small amount of pre-bend in the
spinnaker pole.
4. Tie the 2mm cord from the ring to port
bridle chain plate as this will support the
ring while hoisting and dropping and
limits spinnaker fouling.
5. Connect the 2 shock cords at the end of the chute to the loops under the trampoline. This should
keep the chute taught. These pass UNDER the Cunningham lines.
