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.

C2 Owner's Manual 6

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.

Tools needed

Your C2 parts will come from the factory pre-rigged so that it can be assembled easily, quickly and

without an expensive tool kit, but be advised to have ready with you the following tools:

- Sharp knife

- Cross head screw driver - Philips #2

- 7 mm ring spanner

- 17 mm ring spanner or preferably a hexagonal socket

- 24 mm open spanner

- Torque wrench (optional)

- Shackle tool

- Tape measure

- Duralac sealant (anti corrosive paste)

- Marine grease

Arrival of goods

A typical delivery would consist of 4 packages

- 2 Hull boxes

- 1 Gear box with sails, boom, foils, rudder stocks etc.

- 1 Beam box with main and rear beam

- 1 Mast box with mast and spinnaker pole

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’
