1.1 Owner's Porolio
To help you enjoy the many features, benets, and accessories on your new World Cat, we have provided
you with the following materials:
• World Cat Owner's Manual (model specic)
• Vendor Supplied Manuals for various accessories
• Delivery Checklist
• Warranty Informaon
We refer to this package as the Owner’s Porolio, and will reference it oen throughout this text. The port-
folio contains a wealth of informaon, including advice on safety, operaon, performance, maintenance,
and warranty. Reading and maintaining this informaon is extremely important, and could be the dierence
between a posive and negave experience on the water.
For your convenience, World Cat also provides the NMMA publicaon Sportsh, Cruisers, Yachts Owner’s Manual.
It will be referenced occasionally in your owner's manual, and provides supplemental informaon on safety
and basic boang pracces.
1.2 Warranty Informaon
Upon purchasing your new World Cat, your dealer is responsible for compleng the warranty card and
returning a copy to the factory. The Dealer should provide you with a copy to keep in a secure place so it can
be referenced quickly in the event of a warranty issue. The 10 year limited hull warranty is transferable, and a
copy is included at the back of this manual should you decide to sell your boat.
1.3 Dealer Responsibilies
Our dealers are an extension of the factory and we expect them to provide you with great customer service
to help prepare you for a posive ownership experience. Therefore, we set forth a list of responsibilies for
our dealers as follows:
• Provide courteous service and explanaon of the product prior to the sale.
• Provide sea trials for potenal owners.
• Provide a detailed orientaon of your boat's features and general operaon upon delivery, including
safety and performance.
• Complete and sign delivery checklist.
• Explain, complete, and submit all warranty informaon in a mely manner aer the purchase.
• Provide the customer with the Owner’s Porolio and explain the informaon included therein.
• Provide service aer the sale, or help the customer locate a qualied service shop at home or away.

to present the boat to a marine professional in your area as directed and approved by World Cat.
Once your warranty informaon is processed, World Cat will maintain a record of your boat using the Hull
Idencaon Number (HIN), which is located on the starboard side of the transom. Informaon regarding
the dealership, owner, and the factory installed accessories will be recorded to help you should a problem
arise. Also, you will receive a survey to rate your purchasing experience and the inial impressions of our
company. We ask that you join our family of owners and let us know your feelings about the purchase and
the quality of our product.

4.1 Operator Responsibilies
Prior to enjoying your World Cat, it is important to read and understand all the informaon detailed in
your Owner’s Porolio. Knowing how to operate and maintain the systems on your vessel can make your
experiences safe and enjoyable, as well as increase the performance and longevity of your boat. Federal law
and most state laws clearly indicate that it is the operator’s responsibility to maintain their vessel, and to
operate it in a manner which protects the safety of their passengers and others. Reference page 10 of the
Sportsh, Cruisers, Yachts Owner’s Manual for a detailed list of owner responsibilies.
This manual will provide you a basic understanding of boang pracces; however, we recommend all owners
review federal, state, and local regulaons regarding safety and trac prior to using your World Cat. The U.S.
Coast Guard Auxiliary and U.S. Power Squadrons oer excellent educaonal opportunies on a local level
and are open to anyone. If a chapter does not exist in your area, reference page 10 of the Sportsh, Cruisers,
Yachts Owner’s Manual or contact the following numbers for other educaonal opportunies:
Boang Educaon Hotline [phone]-BOAT (2628)
U.S. Coast Guard Boang Hotline [phone]
4.2 Registraon
Vessels are required by federal and state law to be registered in the state where they are primarily used.
Registraon numbers and validaon sckers must be displayed per regulaons, and a cercate of
registraon must be on board while the vessel is being operated. When traveling away from your home
waters, contact authories at your desnaon to determine if any addional registraon is required. Some
areas require permits or temporary registraons to operate in their waters. When compleng registraon
forms you will be asked for the Hull Idencaon Number (HIN). On your World Cat, the HIN is located on
the starboard side of the transom. This number is unique to your boat and will be important for registering
your vessel, as well as communicang with your dealer and our service department. Including this
informaon in any correspondence or conversaons will help our support network serve you beer.
4.3 Coast Guard Required Safety Equipment
Once you have reviewed safe boang guidelines and led for registraon, it is me to equip your vessel.
The U.S. Coast Guard’s (U.S.C.G.) list of required equipment is shown below. To review the guidelines for
each item, reference pages 23 and 24 of the Sportsh, Cruisers, Yachts Owner’s Manual
or go to hps://www.uscgboang.org/images/420.PDF.
• Audible Signaling Device (Bell, Horn, or Whistle)
• Fire Exnguisher
• Navigaon / Anchor Lights
• Personal Flotaon Devices (PFD’s)
• Visual Signaling Devices
Chapter 4: Safety and Regulaons
NOTICE
Remember to check with state and local agencies to ensure that addional items are not required to
operate your boat in their waterways.

11
4.4 Recommended Safety Equipment
Although not required, there are several addional items which help to ensure safety, and provide
convenience for you and passengers. A list of these items can be found in the Sportsh, Cruisers, Yachts
Owner’s Manual on page 24. Perform an annual inventory to keep tools, spare parts, and safety equipment in
good condion. Immediately replace any items that have been removed from the kit.
4.4.1 NMMA Yacht Cercaon
The NMMA seal means your World Cat is cered by the Naonal Marine Manufacturers Associaon. With
this tag, you are assured your fuel system, electrical system, lighng, venlaon, and steering are not only in
compliance with US Coast Guard regulaons, but also meet the more stringent standards of the NMMA. The
NMMA is a naonal trade organizaon serving all elements of the recreaonal boang industry including
manufacturers of boang equipment. With this tag, you can have condence in the safety of your boat.
Pursuant to NMMA cercaon, all World Cats over 26’ in length are “Yacht Cered” and carry an
appropriate placard. Person and gear capacies are not predetermined, they are le to the operator’s
discreon. Therefore, the amount of load allowed onboard should result from considering all safety
precauons.
Horsepower rangs, however, are set by World Cat and should not be exceeded. Exceeding the factory
recommendaon will result in loss of warranty coverage on your vessel.
4.5 Polluon Regulaons
The Refuse Act of 1899 prohibits throwing, discharging or deposing any refuse maer of any kind (including
trash, garbage, oil and other liquid pollutants) into the waters of the United States. This informaon is
provided in a pamphlet that is normally received when registering your boat. Use the informaon below as
a guideline, but study the pamphlet and understand any local regulaons regarding polluon control. As the
operator, you are also liable for individuals on your vessel disposing of materials in an improper manner.
Use only marine grade replacement parts. Most automove and residenal parts are not suitable
for use in the harsh marine environment. Using them could lead to premature product fail ure,
property damage, or personal injury.
!!! CAUTION
!!! WARNING
Exceeding capacity or recommended horsepower can endanger your passengers and vessel, as
well as voiding any warranty remaining on the boat should failure occur. The maximum horsepower
rang for your 280DC-X is 400 total horse power.
4.5.1 Oil and Hazardous Substances
The Federal Water Polluon Control Act prohibits the discharge
of oil or hazardous substances which may be harmful into U.S.
navigable water. Vessels 26’ in length and over must display a
placard at least 5” x 8”, made of durable material. The placard must
be installed in a conspicuous place in the rigging compartments or
near the bilge pumps and state the following:

4.6 Boang Safety Guidelines
As an owner / operator you should be prepared to handle any situaon which arises before departure, while
underway, or upon return to dock. Careful planning will add safety and pleasure to your experience and give
you the condence to handle emergencies if they develop. Listed below are some general guidelines which
you should follow before any trip:
4.5.2 Disposal of Plascs / Dunnage / Garbage
Boats 26’ in length and over must display a Save Our
Seas Placard which outlines the rules for dumping
waste oshore. The placards must be at least 4” x 9”
and should be displayed in an area visible during normal
operaon. They can be purchased from your dealer or
marine equipment suppliers.
4.6.1 Pre-Departure
• Establish a oat plan and provide it to a person whom you trust. The plan should give the details of
your trip, in cluding where you are going and when you expect to return. If you deviate from the plan,
nofy that person as soon as possible.
• If you ancipate operang in a new area, understand the local rules and request charts or informaon
on any haz ards you may not be aware of.
• If you are towing the boat, inspect the trailer including res, lights, brakes, winch, and overall
mechanical appearance. See Sportsh, Cruisers, Yachts Owner’s Manual, page 105.
• Verify that you have all necessary safety equipment. This should include all the USCG required
equipment as well as spare parts or other items you decided to include.
• Check fuel levels and determine if you require addional fuel for your trip.
• Examine the weight of the gear on your vessel and make sure you are not overloaded. Distribute the
weight evenly on your vessel to ensure predictable performance.
4.6.2 Launching
• Prepare your boat prior to backing down, (i.e. secure all loose items, install garboard drain), then
launch your ves sel and move away quickly.
• Move your vessel away from the dock and complete a full system check. Ensure that electronics,
pumps, and safety equipment are in working order.
• Instruct a passenger on the operaon of the boat, and the locaon and funcon of all safety
equipment onboard. You should never be the only person capable of safely operang your vessel.
4.6.3 Underway (See Chapter 5 on Performance)
• Obey all “Rules of the Road” and any local regulaons. Use the informaon located on page 25 of
the Sportsh, Cruisers, Yachts Owner’s Manual to understand right-of-way and the various
navigaonal and hazard indicators you will see on the water.
• Never operate a boat under the inuence of alcohol or drugs.
• Do not allow individuals under the age of 16 to operate the vessel. Maintain direct supervision of
inexperienced operators.
• Ensure that all passengers are safely seated while underway, and are using the hand rails World Cat
has provided to remain securely in their seats.

13
• Use your electronics and judgment to remain abreast of changing weather. Storms develop quickly and
you should be prepared to protect your passengers and vessel. See page 22 of the Sportsh, Cruisers,
Yachts Owner’s Manual for more ps on weather.
• Maintain a safe speed and respect other boaters as well as those on land. Obey all “No Wake Zones”
and be aware of smaller vessels. The wake you produce could endanger other cras and
their passengers.
• Know the limitaons of your cra and your experience. Understand the boat’s handling characteriscs
and do not aempt to operate the vessel in condions that are unsafe or beyond your experience level.
4.6.4 Returning
• Obey navigaonal markers and be aware of any dal changes since departure.
•Collect and dispose of refuse properly to maintain our waters for future generaons.
• Prepare your boat for loading before moving to the dock. Quickly pull your vessel from the water and
move away from the ramp to complete the preparaon for trailering.
•Verify that trailer systems are working properly and all items are secured before leaving.
•Wash the boat and perform general maintenance upon returning home. (See instrucons in Chapter 5).
As stated above, these are only general guidelines for safe boang. We recommend using these and any other
available resources to protect your passengers as well as your vessel. Checklists can be an important tool in
accomplishing this; see the example on pages 44 & 45 of the Sportsh, Cruisers, Yachts Owner’s Manual.
4.7 Trailering
Due to the nature of the hull, catamarans require specialized trailers. Your dealer will be able to provide
one, as well as informaon on safe trailering pracces. Tow vehicles should be rated to handle the load and
stresses which accompany trailering your boat. A properly matched trailer should carry 5-10% of the total
vessel weight on the tongue. Roune inspecons should be performed on the vehicle and trailer prior to
each trip, and thorough checks scheduled on an annual basis.
4.8 Anchoring
World Cat supplies an anchor and anchor windlass as standard equipment on the 280DC-X. The anchor
we supply is known as a plow style. However, there are several types of anchors available, each designed
to operate in specic boom condions. Your dealer can provide informaon on which styles are most
eecve in your area. See page 56 of the Sportsh, Cruisers, Yachts Owner’s Manual for more informaon and
ps concerning anchoring.
!!! CAUTION
Never anchor your boat o the stern. The weight at the transom, combined with adverse sea
condions could allow water to enter the boat over the transom wall.

4.9 Shallow Water
Although your World Cat draws a small amount of water for its size, shallow water should be a concern of
all boaters. To avoid this hazard, pay parcular aenon to navigaonal markers and know the area you are
operang in. Be aware of dal changes, including those that have occurred during your trip. Rocks, stumps,
or other hazards are more prevalent in shallow water and can cause major damage to your hull boom.
Engines can also suer damage if they are allowed to run in the sand or mud.
If you do become grounded, lt the motors up to reduce the dra at the transom. Oen this will solve the
problem; however, it may be necessary to rock the boat from side to side to break the sucon along the keel.
If you are grounded on an incoming de, allowing the water to rise can help. Being grounded on an outgoing
de is a larger issue, you need to act quickly to free your boat and avoid being driven further aground. Use
the anchor to secure the boat and await the incoming de, or use it to pull yourself free.
4.10 Emergency Situaons
Unfortunately, even the safest boang pracces cannot eliminate the potenal of emergency situaons
developing. Therefore you should prepare yourself, and your crew, to handle any problems that may arise.
Establish specic plans for res, man overboard, collision, etc., and review them with your passengers prior
to deparng. Planning allows people to remain calm, and gives everyone the condence to resolve the
problem. Secon 4 of the Sportsh, Cruisers, Yachts Owner’s Manual provides informaon on emergency
procedures. Below is important informaon which all owners should be aware.
4.10.1 Emergency Stop Switch
Lanyard clips are provided on all World Cats and when used properly, provide
an emergency stop for the engines should the driver fall from the helm posion,
or need to perform an emergency shutdown to respond to or avoid an accident.
The clip aaches the driver to the ignion panel using a cord. A pull on the
cord will release the clip from the shut-o switch on the panel and shut down
the engines. To restart the engines, turn ignion switches to the o posion,
return binnacle to neutral posion, insert safety lanyard back into clip, and then
turn ignion switches back on. This should only be used to prevent or react to
accidents, and the operator is solely responsible for the decision.
4.10.2 Communicaon
If you witness an emergency or become involved in one, you should request assistance via radio
communicaon or visual signals. Review the informaon in Secon 4 of the Sportsh, Cruisers, Yachts Owner’s
Manual for detailed informaon on how and when to request assistance.
4.10.3 Rendering Assistance
Owners are required by law to render assistance to other boaters involved in an emergency situaon such as
re, collision, casualty, etc., as long as it does not endanger your vessel or its passengers.
4.10.4 Reporng Accidents
Federal regulaons require that operators involved in an accident le a wrien account of the situaon
within 48 hours. Reports should be submied to the State Boang Law Administrator. You can obtain forms
through the USCG or local authories (i.e. harbor patrol, sheri or police oces). In the event that a casualty
or disappearance occurs as the re sult of an accident, you must nofy the authories immediately by phone
or radio and ll out a wrien statement.

15
• Dizziness
• Nausea / Voming
• Headache / Throbbing in the temples
• Fague
• Muscular twitching
• Inability to focus or think clearly
If you or any of passengers experience any of these symptoms, leave the area and nd a source of fresh air
immediate ly. If your symptoms persist, seek medical aenon.
4.10.5 Weather
Pay aenon to weather paerns. If you nd yourself in the path of a storm, seek shelter immediately. If
you cannot reach a dock, seek refuge inside the boat while the storm advances. Never get in the water and
stay clear of metal components on your boat. If lightning strikes, it would likely pass through metal objects
seeking a ground.
4.10.6 Towing
Due to an accident or loss of power, it may become necessary to tow another vessel or have your boat
towed. If you are providing assistance, never aempt to tow a boat larger than your own. Be certain to
use proper lines (ropes) and raonal judgment to prevent further damage. Tow lines are under heavy
strain, therefore passengers should remain clear of the lines to protect themselves from injury. For more
informaon on towing, reference page 39 of the Sportsh, Cruisers, Yachts Owner’s Manual.
4.11 Carbon Monoxide (CO)
One of the most important consideraons when dealing with boang safety is carbon monoxide. Commonly
referred to as CO, carbon monoxide is a colorless, odorless, and tasteless gas emied from any engine
exhaust. Including inboards and outboards. A CO parcle is close in weight to the air we consume; therefore
it does not rise or fall in the atmos phere, but accumulates in enclosed spaces. Boat owners with enclosed
heads, cabins, or canvas enclosures should pay parcular aenon to CO. Be aware that fumes produced on
your boat can aect other vessels and other boats can aect you. A primary concern is the use of generators
when boats are moored adjacent to each other.
Carbon Monoxide is poisonous and potenally fatal if inhaled over an extended period of me.
Symptoms of CO poisoning include:
!!! DANGER
Carbon Monoxide (CO) is a colorless, odorless, and tasteless gas pro duced by the exhaust system of any
combusble engine. CO can cause brain damage or death if inhaled over an extended period of me. To protect
yourself and your passengers, never block the venlaon outlets in cabins, consoles, or other enclosed spaces.

5.1 Overview
This chapter will provide informaon on the performance characteriscs of your catamaran. This is not a
substute for seamanship training or hands-on experience. First me boat owners should use the resources
detailed in Chapter 4 to learn proper methods of boat operaon. Experienced boaters who have never
owned a catamaran should study this chapter completely. Do not assume that previous boang experience
will apply to all situaons, as there are several subtle dierences in the handling characteriscs of twin
hulled boats. For experienced catamaran owners, this chapter should be a reference.
5.2 Motor Trim
The smooth riding characteriscs of a catamaran are a result of the twin hull design. Their ability to slice
through oncoming waves is far superior to the pounding characteriscs seen on convenonal vessels. Motor
trim plays an integral part in how your catamaran accomplishes this. In a level or bow down atude, your
boat will slice through larger chop but you may experience sluggish performance, a weer ride and increased
bow steering in a following sea. In a bow up atude the boat will perform beer, but may ride less smoothly.
Experiment with the trim sengs in various sea condions to determine what you are most comfortable
with. When using the trim to correct a lisng condion, imagine an “X” connecng the starboard engine to
the port bow, and port engine to the starboard bow (see drawing below).
5.2.1 Bow Up Condion
To correct a bow up condion on the port sponson, adjust the
motor trim “down” on the starboard engine. This will help the
starboard sponson to rise and level the vessel. If moving to the
lowest trim seng on the starboard engine does not correct
the list, trim the port engine “up” to assist the change. Reverse
the instrucons to accommodate for a bow up condion on the
starboard sponson.
5.2.2 Bow Down Condion
To correct a bow down condion on the port sponson, adjust
the motor trim “up” on the starboard engine. This will help the
starboard sponson to fall and level the vessel. If cavitaon occurs
on the starboard engine, lower it to correct the problem, then
trim the port engine “down” to assist the change. Reverse the
instrucons to accommodate for a bow down condion on the
starboard sponson.
5.3 Engine Controls
All factory rigged boats will come equipped with a binnacle control specic to your
type of engine. Located at the helm, the binnacle controls the throle, shi, and trim
mechanisms for your engine. For diagrams and general informaon about this system,
review pages 80 thru 83 of the Sportsh, Cruisers, Yachts Owner’s Manual. Also read the
owner’s manual provided by your engine manufacturer to determine how to operate
the features on your binnacle. If any components of this system need to be replaced,
be certain to use the same style and length as the original equipment.

5.4 Steering Controls
Catamarans oer unsurpassed steering control. The wide spacing of the engines, advanced steering
components, and handling characteriscs of the World Cat hull give operators exceponal maneuverability
in even the ghtest spaces.
Because of the superior tracking abilies of the World Cat hull, over-steering can present a problem,
especially for owners accustomed to operang convenonal boats. Convenonal vessels have a tendency to
lose tracking abilies in rough and following sea condions, making constant course correcons necessary.
However, catamarans do not exhibit those traits and require operators to take a “hands o” approach. To do
so, relax your grip and resist the urge to make constant correcons.
5.5 Steering Maintenance - Twin Engines
The design of a catamaran hull requires a special steering system which features a “liquid e-bar”, as
opposed to the mechanical version used in convenonal boats. For this reason your World Cat is equipped
with a hydraulic steering system, featuring steering cylinders mounted on each engine and a steering system
valve. This system enables both engines to respond in unison to adjustments at the helm.
In order to maintain the excellent steering characteriscs of your boat, occasionally you will need to adjust
the steering system to realign the motors (known as motor toe). To do so, follow these instrucons:
• Using the helm, center the starboard motor.
• Find the steering system valve, located under the inspecon port on the center of the transom.
• Open the valve by rotang it 90 degrees (the handle will be parallel to the valve body when
open). This will isolate the port engine, so that it can be adjusted manually.
• Center the port motor manually; then close the steering system ball valve and reinstall the
inspecon port.
Similar to hydraulic braking systems in an automobile, it may become necessary to bleed the steering system
occasionally to remove air from the lines. We have provided diagrams of the steering system in secon 5.6
and 5.7, and the Teleex™ owner’s manual in your Owner’s Porolio. Use these resources, and your dealer,
to keep the steering system in excellent working order. Be aware, these are roune maintenance procedures
and are not covered under warranty by World Cat.
!!! CAUTION
Rounely check hydraulic uid levels and all connecons for leaks or any sign of mechanical failure.
Lubricate all mechanical parts at least annually with high quality marine grease. Failure to do so may
result in impaired or unresponsive steering.

5.7 Power Steering System - Bleeding Instrucons
Reference the bleeding instrucons provided by the Teleex™ owner’s manual, which is included in your
Owner’s Porolio. Use them in conjuncon with the instrucons and diagram below to bleed the steering
system. This should be done annually only by a trained technician; any faulty parts should be replaced
immediately.
5.7.1 Step 1
• With the Power Purge turned "OFF", aach helm
ng and leads.
• Aach one of the leads to the bleeder valve on the
Power Assist Pump.
• Open the bleeder valve using a 5/8" wrench.
• Turn the Power Purge unit "ON".
• Watch for air bubbles in the clear hydraulic lines. Once
no more bubbles can be seen and there is a steady
ow of hydraulic uid through the lines, allow the
Power Purge to run for an addional 60 seconds.
• The helm is now full of uid. Turn Power Purge "OFF".
Close bleeder valve and dis-connect line from the
Power Assist Pump. Place dust cap back on bleeder valve.
5.7.2 Step 2
• Aach the four lines to each of the bleeder valves on the steering cylinders.
• Open each of the four bleeder valves.
• Turn Power Purge "ON".
• Turn the steering wheel slowly 20 mes clockwise, then slowly 20 mes counter-clockwise.
5.7.3 Step 3
• With Power Purge turned "ON", move both engines through their full range of moon
(This will help remove any air bubbles sll trapped inside the cylinders).
• As a nal precauonary step, pull on the engines rmly at the ends of their normal range of moon
(This will also help to insure all of the air is out of the cylinders).
5.7.4 Step 4
• Turn the ignion key for the port engine "ON". This will turn the Power Assist Pump "ON”.
• Repeat "Step 2".
• If no more bubbles can be seen then the bleeding is complete. Turn the Power Purge 'OFF". Close all
four bleeder valves. Disconnect the four lines from the cylinders and both lines from the helm.
Remove the helm ng and replace it with vent cap.
• If bubbles are sll present in lines, then bleeding was not successful. Repeat enre process.
NOTICE
World Cat strongly suggests you have your dealer or trained marine technician perform roune
maintenance or repairs on your steering system. Improper repairs may result in impaired or
unresponsive steering, which could pose risk of damage or injury.
