INTRODUCTION
Your dealer and the staff at OUYANG would like to congratulate you on
your new MATILDA 20, and wish you and your crew many happy days of pure
sailing fun in the years to come.
To help you enjoy your MATILDA 20 more, and make it a trouble free
boating season for you, we have made a check list of items and encourage
you to be familiar with them.
I. PRELIMINARIES
1. Insurance on boat and contents still effective?
2. Club or marina dues paid? Mooring or slip ready?
3. Familiar with local trailer operating regulations?
4. Familiar with local boating rules and laws?
5. Safety gear aboard, arid all equipment operational?
II. LOADING
1. Stow all necessary boating gear properly to prevent rattling.
2. Sails in? Battens? Rudder? Etc . . .
3. Mast may ride on cabin roof secured fore and aft on bow and
stern rail, or on trailer under boat. You may require to tie a red
flag on aftermost end as required by local trailering laws.
III. TRAILER/TRAILERINC
1. Allow 100-200 lb. Tongue weight on trailer. Check tire pressure,
and also condition of wheel bearings. They might need greasing.
2. Check that trailer lights are functioning. It is advisable to
carry a couple of extra trailer light bulbs and fuses.
3. The keel should be lowered to rest with its full weight on the
trailer. Do not tow trailer with keel hanging from winch cable.
4. Boat snug in bow roller of trailer? Safety chains on hitch? Etc.
Let’s take off to the launch ramp!! But watch your speed limit.
Maximum towing speed is usually lower than maximum highway speeds.

LAUNCHING AND RIGGING
IV RIGGING BEFORE LAUNCHING
Step your mast before launching. It is much simpler on land than water.
Also it gives the tires, wheel bearings, and trailer lights a chance to
cool down before submerging them.
Make sure there are no overhead wires, tree branches, or such
obstacles where you are stepping the mast up and between you and the
launching ramp. When mast is stepped on factory trailer (8" wheel),
the impaired vertical clearance is about 30 feet.
A. Stepping the mast:
1. Lay mast on cabin roof, mast foot towards bow section, masthead to
stern, groove of mast facing down.
2. Attach spreaders, upper shrouds through outboard spreader ends (and
tape ends with black electrical tape) to aft shroud plates. Lower
shrouds on fore shroud plates. Backstay and bridle attached to stern
plates. WATCH that you DON'T fasten backstay over and around optional
stern rail! Leave forestay unattached for now.
3. Check that all halyards are free and cleated. Jib halyard is to
port with rope tail along groove side of mast. Main halyard is to
starboard with wire along groove side of mast.
4. Open all turnbuckles to about one-third, and tape turnbuckle toggles
vertical to prevent twist when raising mast.
5. Walk the mast back, one person at foot of mast in foredeck and other
mid mast in cockpit. Person in foredeck keep mast foot down and centre
mast heel slot into bolt on mast channel, while person in cockpit raises
mast as he walks towards bow.
6. Person in foredeck at the same time pu11s on forestay, and fastens
same when mast is upright. Adjust all turnbuckles for proper tension.
Lower shrouds less tension than upper – no “S” bend in mast – recheck
when under sail. (See Mast Tuning).
B. Boom
l. Attach gooseneck fitting into mast groove.
2. To rig mainsheet and boom vang, see figures 2 and 3.

V. PRELAUNCHING CHECKS
1. Raise keel up as far as possible to clear trailer and lock
keel winch.
2. Untie trailer tie-downs, etc.
3. Attach bow line, and if you wish--fenders, stern line, etc.
4. If you have outboard motor, mount same and gas tank.
5. Check again that all necessary boating gear is on board.
6. Disconnect trailer light plug from car end.
VI. LAUNCHING
1. Back trailer down ramp. Have one person on board and another
on the ramp to hold bow line and guide driver.
2. Slack trailer bow eye line.
3. As soon as stern section of boat floats free from stern section of
trailer, unsnap trailer bow-eye line and give the boat a push at the
bow--your MATILDA will be water-borne.
4. If ramp is not steep enough, release tilt-up lever of trailer so
trailer will tilt and boat will slide off into the water.
5. Watch that tail pipe of car does not touch water.
VII. DOCKSIDE PREPARATIONS
l. Set up rudder, motor or paddle your MATILDA to your dock or
mooring with at least 15" of water depth.
2. Face bow of boat into the wind and bend on sails.
JIB OR GENOA
a. Fasten tack to hole in bow plate immediately behind forestay.
b. Hank jib/genoa to forestay.
c. Attach Jib Halyard to head of sail. Make sure you hold halyard
shackle tight in your hand and not let it run up the mast. Other-
wise you would have to either shin up the mast to get it down, or
lower your mast.
d. Tie in sheets in centre to clew
e. Lead sheets outboard of shrouds through blocks, and around sheet
winches and jam into camcleats.

Page Four
MAINSAIL
a. Slide foot of sail into boom groove from fore end.
b. Secure tack in gooseneck with pin.
c. Tighten foot of sail and lash clew to cleat on outboard end of
boom, slide Head Into mast groove and attach main halyard.
d. Insert Battens.
With sails bent on and sheet rove, you are ready to get underway.
But please take a few moments to ensure everything is in order.
VIII. MAST TUNING
Improper tuning or handling of spars and rigging can cause mast or
rigging failures. The following are few suggestions for tuning your
mast and rigging:
1. Mast should be set straight athwartships with a slight rake aft
of about 3 (three) Inches.
2. Shrouds must be kept at a reasonable tension to avoid
unnecessary compression on the mast causing it to bend.
3. Forestay/backstay ‘just firm’ with backstay slightly tighter.
4. While sailing to windward in a series of tack, make necessary
adjustments of the turnbuckles on the slack leeward shrouds after
observing the mast on the opposite tack.
5. Check mast by sighting from the deck up will reveal whether
further adjustments are necessary.
6. For better windward performance, the jib stay and backstay may
be tightened up more. Remember to slack off the amount you “took—up”
after the sail to avoid unnecessary strains on the rigging.
7. UNDER NO CIRCUMSTANCES SHOULD ANY OF THE RIGGING BE SET UP
“BAR-TIGHT”.

THE DROP KEEL
IX. KEEL/KEEL WINCH
The MATILDA drop-keel works on a four-pulley system. The bearings on
these pulleys must be greased as frequently as needed. Two to three
checks a year should prevent them from freezing up. Grease the pulleys
early Spring, mid Summer, and late Fall if needed. To get at the
pulleys:
1. Unscrew top panel of keel housing on starboard side.
2. Grease with “wheel bearing grease” available at most automotive
supply stores.
At the bottom of the aft section of the keel housing, there is a
stainless lock-pin bolt that prevents the keel from going down further
beyond this point. Do not remove this bolt. If you must, do so only
when boat is out of the water. Caulk with heavy marine sealant when
you rebolt this fitting!
When using the keel winch, the winch pawl lock works automatically
when raising the keel (clockwise direction). When lowering the keel,
the winch pawl lock must be released BEFORE going in the anticlockwise
direction. Once a desired position is reached, the lock pin must be
set back on the ratchet before taking your hand off the winch handle.
FAILURE TO LOCK WINCH PAWL LOCK OR MAINTAIN PROPER CONTROL OF WINCH
CAN LEAD TO SEVERE DAMAGE TO THE BOAT AND POSSIBLE INJURY TO THE
OPERATOR.
It is advisable to remove winch handle and store below deck especially
when boat is left unattended at mooring.
The keel must be let to rest on trailer when trailering and should be
raised as far up as possible when launching or recovering at ramp.

SAILING BASICS
Before we go any further in this Manual, we would like to outline the
very basic forms of sailing. Please note this is not a “cramp” course in
how to sail, nor a detailed lesson.
And please don’t consider yourself a “know all” when you finish reading
the Manual. The object of the entire manual is to acquaint newcomers to
sailing, and those skipping or crewing on a MATILDA 20 for the first
time . . . . to help you and your crew rig and sail your MATILDA 20
faster . . . . and safely.
Some important basics are:
A. Sitting position: Learn to sit properly, and always sit facing the
sail, never with your back to it.
B. Balance: Distribute crew and gear weight evenly. Avoid getting the
boat ‘stern heavy’ (weight too far aft, move weight fore to correct) or
‘bow heavy’ (weight too far fore, move weight aft to correct).
C. Heeling: a. Heeling to Leeward: if your boat heels because of too
much wind, you can correct this by hiking out one the weather side OR If
this doesn’t help, let your sail out or head up.
b. Heeling to Windward: This is when weight of the skipper and/or
crew is too far over on the weather side. You should never heel your
boat to weather.
D. Sail it Right! Sailing right is a matter of keeping your boat at
the correct angle for the wind conditions. Heel the boat over in very
light winds so the sail will hold its shape. On a windy day, try to
hold, the boat as flat as possible.
E. Heading up: Know how to ‘head up’, into the wind when you want to
avoid excessive heeling.
F. Falling off: You ‘fall off’ when you want to veer your boat away
from the wind--that is, the bow of the boat moves away from the wind.
G. Coming about: Coming about is a form of turning. The boat heads up
into the wind and crosses it thus changing the direction of the craft.
H. Jibing: Jibing is a form of turning, and used when it is more
convenient than coming about. It is similar to ‘falling off’ except the
sail changes sides when you jibe and it does not when you ‘fall off’.
Remember, ALWAYS WATCH YOUR SAILS.

GENERAL SAILING CHARACTERISTICS OF THE MATILDA 20
A. LIGHT WINDS
In light wind it is difficult to sail to windward very tightly close
hauled. It does not produce drive in the boat. Sails should then be
eased off considerably including the boom vang in order to beat to
windward without drifting. Crew weight on leeward side to give slight
heel might help.
Leave keel half down on this tack.
In lights airs, MATILDA 20 does fairly well in a beam reach with main
and genoa. In a Force 3 breeze, one would make about 4 knots and in a
Force 5 possible 7 knots. Leave keel half down.
B. MEDIUM WINDS
Perhaps this condition would be most suitable to skipper and crew. As
the wind force increases, so does the MATILDA 20 ability to point. One
may have to lower the keel all the way down. The MATILDA 20 will run
very well in about a force 5 and one would make about 8 knots. On this
tack, the MATILDA 20 will get up and plane very easily. One can have the
board all the way up and the MATILDA 20 will ‘track’ well with no yaw,
pitch, or roll.
C. HEAVY WINDS
The MATILDA 20 is an extremely stable and dry boat. Sailing close-hauled
to windward in heavy weather is not good practice as the boat will not
make good time due to sudden wind shifts resulting in a zig zag
performance.
Broad reaching in heavy weather would be very exciting and one could
easily plane the MATILDA 20 safely. The keel would preferably be a
quarter way down to cut down any pressure on the rudder. It is necessary
to move crew weight aft.
A dead run in this wind condition requires skill in order to keep the
boat under control while planing. Accidental jibing could occur from
one, tack to another. It is therefore good practice to sail slightly off
the dead run course on one tack and when able, jibe to opposite tack in
order to stay on course as close as possible.

THE THREE POINTS OF SAILING ARE:
1. Beating or Closehauled:
A boat is said to be beating or closehauled when she is headed on
a course as close to the winds as she can sail with her main boom
sheeted over the boat.
2. Running Free:
When a boat is sailing in the same direction as the wind she is said to
be running free or sailing before the wind, with her main boom let out
at nearly a right angle to the boat.
3. Reaching:
We say a boat is reaching when the wind is coming over the side of the
boat. There are three types of reaches. Note the difference in each in
the direction in which the wind is coming over the side of the boat, and
the way the sail is trimmed in the following “Sailing Circle”.

HAUL-OUT AND RECOVERY PROCEDURES
Trusting that you had an enjoyable sail and you are ready to haul out
your MATILDA 20 onto your trailer, the procedures run in reverse
to our previous steps. We would like to emphasize the following
points:
1. Store your sails, sheets and gear neatly.
2. Before recovering boat onto trailer, raise keel up as far as
possible to clear the trailer. Do not forget to lower the keel again
once it is on the trailer to take the tension off the keel cable.
3. Centre boat on trailer during recovery.
4. Lower mast by unfastening forestay turnbuckle, and walking mast
back. You may want to leave the backstay and shrouds to their
chainplates as is while trailering. But make sure these rigging and
forestay are secured along the length of mast with shock cord ties or
lines.
5. A good hosing of deck and especially under the waterline after
each major haul out keeps the boat looking sparkling clean.

MAINTENANCE
The following maintenance tips should be of value:
A. SPARS:
The mast and boom is silver anodized and protected against corrosion.
Dust, dirt, salt, smoke will stick to this coating, which can further be
protected by applying a good paste wax (Simonize, etc.)
B. RIGGING:
Clean rigging means clean sails. Wipe with a damp cloth before stepping
the mast.
Also, do periodical checks of turnbuckle take—ups, cotter pins, etc. and
keep spare parts of rigging gear if necessary.
If dacron line becomes stiff or dirty, soak in warm soapy water which
will make the line soft, clean and flexible again.
C. SAILS:
When storing sails in sailbags, always fold and bag them neatly. Remove
battens from sail pockets. If sails are wet, dry by hoisting them on a
calm day or stow below spread out to dry. Clean with a wet sponge or
hose off if sails become caked with salt. Check condition of sails
periodically for small tears and chafe. Send sails to a sailmaker if
necessary before it becomes too costly to repair.
HARDWARE:
The hardware of your MATILDA 20 is made from many types of materials,
all of which can cleaned and brought back to a bright finish with
automotive chrome cleaner or household detergent.
Winches must be cleaned and lubricated. Lubrication is important on all
moving parts. And this includes turnbuckles, sheaves, winches, etc. If
any part needs replacing – replace!
E. WOODWORK:
Teak wood is weather resistant due to its natural oils. In due course,
the teak turns grayish or blackish. This can be quickly remedies by
first sanding with a 80 grit garnet paper and oiled with teak oil.

Page Twelve
The mahogany used are finished with a satin varnish, and are used
in the berth and joint trims.
Interior bulkheads are formica applied. They do not require
exterior treatment. one should however maintain proper housecleaning.
F. GELCOAT AND FIBREGLASS:
A periodic maintenance programme a good cleaning and waxing of
the fiberglass surfaces will save expensive maintenance costs at a
later date.
Good hosing of fresh, warm water and chamois will do the cleaning
Job. Dull or faded spots should be waxed. Wax liberally at waterline and
at least 10 (ten) inches above.
In due course, you might experience ‘streaks’ on the gelcoat, or
what is termed as ‘hairline cracks’ which cannot be covered, filled
or repaired successfully. They are usually found in curves and
sharp corners, and are the results of the boat working in. These
are harmless in that it is only superficial and is not extended
beyond the gelcoat into the fiberglass.
