CHAPTER 1
SAFETY AND REGULATIONS
OPERATOR RESPONSIBILITIES
Prior to enjoying your World Cat, it is important to read and understand all the information detailed in your
“Owner’s Portfolio”. Knowing how to operate and maintain the systems on your vessel can make y our 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 8 of the Sportfish, Cruisers, Yachts Owner ’s Manual
for a detailed list of owner responsibilities.
This manual will provide you a basic understanding of boating practices; however, we recommend all owners
review federal, state, and local regulations regarding safety and traffic prior to using your World Cat. The U.S. Coast
Guard Auxiliary and U.S. Power Squadrons offer excellent educational opportunities on a local level and are open to
anyone. If a chapter does not exist in your area, reference page 8 of the Sportfish, Cruisers, Y achts Owner’s Manual or
contact the following numbers for other educational opportunities:
BOATING EDUCATION HOTLINE.................................1-800-336-BOAT (2628)
U.S. COAST GUARD BOATING HOTLINE....................1-800-368-5647
REGISTRATION
Vessels are required by federal and state law to be registered in the state where they are primarily used. Registration numbers and validation stickers must be displayed per regulations, and a certificate of registration must be on
board while the vessel is being operated. When traveling away from your home waters, contact authorities at your
destination to determine if any additional registration i s required. Some areas require permits or temporary registrations to operate in their waters. When completing registration forms you will be asked for the Hull Identification
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 w ell as, communicat ing with your dealer and ou r service department. Including this information in any correspondence or con versations will help our support network
serve you better.
COAST GUARD REQUIRED SAFETY EQUIPMENT
Once you have reviewed safe boating guidelines and filed for registration, it is time 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 17 and 18 of the Sportfish, Cruisers, Yachts Owner’s Manual.
• Audible Signaling Device (Bell, Horn, or Whistle)
• Fire Extinguisher
• Navigation / Anchor Lights
• Flotation Devices (PFD’s)
• Visual Signaling Devices
NOTICE
Remember to check with state and local agencies to ensure that additional items are not required to operate
your boat in their waterways.

World Cat
RECOMMENDED SAFETY EQUIPMENT
Although not required, there are several additional items which help to ensure safety, and provide convenience
for you and passengers. A list of these items can be found in the Sportfish, Cruisers, Yachts Owner’s Manual on page
18. Perform an annual inventory to keep tools, spare parts, and safety equipment in good condition. Immediately
replace any items that have been removed from the kit.
! CAUTION
Use only marine grade replacement parts. Most automotive and resident ia l parts are not suitable for use in
the harsh marine environment. Using them could lead to premature product failure, property damage, or
personal injury.
CAPACITY INFORMATION
On all boats under 26 feet in length, the manufacturer
is required to provide capacity information. If you own a
250 SF, 250 SF, or 250 DC you will find a rectangular
metal plate near the helm. This plate will provide information on horsepower ratings and total capacities which
include person capacities, motor(s) and gear. As an owner
you should be aware of the weight on board. Exceeding
capacity can endanger your passengers and vessel, as well
as void any warranty remaining on the boat should a failure
occur. Remember this is a guideline for normal operation,
and does not release you from responsibility should an
accident occur. You must use rational judgement when
adverse conditions are expected, and reduce your loads to
create a margin of safety.
Pursuant to NMMA certification, all World Cats over 26’ in length are “Yacht Certified” and carry the placard
shown below. Person and gear capacities are not predetermined, they are left to the operator’s discretion. Therefore,
the amount of load allowed onboard should result from considering all safety precautions.
Horsepower ratings, however, are set by World
Cat and should not be exceeded. The second
page in Chapter 5 of this manual will provide
information on the maximum horsepower ratings for your boat. Exceeding the factory recommendation will result in loss of warranty
coverage on your vessel.

World Cat
POLLUTION REGULATIONS
The Refuse Act of 1899 prohibits throwing, discharging or depositing any refuse matter of any kind (including
trash, garbage, oil and other liquid pollutants) into the waters of the United States. This information is provided in a
pamphlet, that normally received when registering your boat. Use the information below as a guideline, but study the
pamphlet and understand any local regulations regarding pol lution control. As the operator, you are also liable for
individuals on your vessel disposing of materials in an improper manner.
OIL AND HAZARDOUS SUBSTANCES
The Federal Water Pollution Control Act prohibits the discharge of oil or hazardous substances which may be
harmful into U.S. navigable water. Vessels 26 feet in length and over must display a placard at least 5 by 8
inches, 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:
DISPOSAL OF PLASTICS/DUNNAGE/GARBAGE
Boats 26 feet in length and over must display a Save Our Seas Placard which outlines the rules for dumping
waste offshore. The placards must be at least 4” x 9” and should be displayed in an area visible during normal
operation. They can be purchased from your dealer or marine equipment suppliers.

BOATING SAFETY GUIDELINES
As an owner/operator you should be prepared to handle any situation 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 confidence to handle emergencies if they develop. Listed below are some general guidelines which you should follow
before any trip:
PRE-DEPARTURE:
• Establish a float plan and provide it to a person whom you trust. The plan should give the details of your
trip, including where you are going and when you expect to return. If you deviate from the plan, notify
that person as soon as possible.
• If you anticipate operating in a new area, understand the local rules and request charts or information on
any hazards you may not be aware of.
• If you are towing the boat, inspect the trailer including tires, lights, brakes, winch, and overall mechanical
appearance. For trailering information see page 4
• 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 additional 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.
LAUNCHING:
• Prepare your boat prior to backing down, (i.e. secure all lose items, install garboard drain), then launch
your vessel 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 operation of the boat, and the location and function of all safety equipment
onboard. You should never be the only person capable of safely operating your vessel.
UNDERWAY: (INFORMATION ON OPERATION AND HANDLING IS LOCATED IN CHAPTER 2)
• Obey all “Rules of the Road” and any local regulations. Use the information located on page 19 of the
Sportfish, Cruisers, Yachts Owner’s Manual to understand right of way and the various navigational and
hazard indicators you will see on the water.
• Never operate a boat under the influence 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.
• Use your electronics and judgement to remain abreast of changing weather. Storms develop quickly and
you should be prepared to protect your passengers and vessel. See page 16 of the Sportfish, Cruisers,
Yachts Owner’s Manual for more tips 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 crafts and their passengers.
• Know the limitations of your craft and your experience. Understand the boats handling characteristics and
do not attempt to operate the vessel in conditions that are unsafe or beyond your experience level.

World Cat
RETURNING
• Obey navigational markers and be aware of any tidal changes since departure.
• Collect and dispose of refuse properly to maintain our waters for future generations.
• 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 preparation 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 instructions in Chapter 4).
As stated above, these are only general guidelines for safe boating. 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 page 35 of the Sportfish, Cruisers, Yachts Owner’s Manual.
TRAILERING
Due to the nature of the hull, catamarans require specialized trailers. Yo ur dealer will be able to provide them, as
well as, information on safe trailering practices. 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. Routine inspections should be performed on the vehicle and trailer prior to each trip, and thorough checks
scheduled on an annual basis.
ANCHORING
World Cat offers an anchor and anchor windlass as optional equipment on all boats. The anchor we supply is
known as a plow style. However, there are several types of anchors available, each designed to operate in specific
bottom conditions. Your dealer can provide information on which styles are most effective in your area. See page 46
of the Sportfish, Cruisers, Yachts Owner’s Manual for more information and tips concerning anchoring .
! CAUTION
Never anchor your boat off the stern. The weight at the transom, combined with adverse sea conditions
could allow water to enter the boat over the transom wall.
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 particular attention to navigational markers and know the area you are operating in.
Be aware of tidal 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 bottom. Engines can also suffer damage if
they are allowed to run in the sand or mud.
If you do become grounded, tilt the motors up to reduce the draft at the transom. Often th is will solve the p roblem; however, it may be necessary to rock the boat from side to side to break the suction along the keel. If you are
grounded on an incoming tide, allowing the water to rise can help. Being grounded on an outgoing tide 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 tide, or use it to pull yourself free.
EMERGENCY SITUATIONS
Unfortunately, even the safest boating practices cannot eliminate the potential of emergency situations dev eloping. Therefore you should prepare yourself, and your crew, to handle any problems that may arise. Establish specific
plans for fires, man overboard, collision, etc., and review th em with your passengers prior to departing. Planning
allows people to remain calm, and gives everyone the confidence to resolve the problem. Section 4 of the Sportfish,
Cruisers, Yachts Owner’s Manual provides information on emergency procedures. Below is important information
which all owners should be aware.
1-5
World Cat
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 position, or need to perform an emergency shutdown to respond to
or avoid an accident. The clip attaches the driver to the ignition panel using a cord. A pull on the cord will
release the clip from the shut-off switch on the panel and shutdown the engines. To restart the engines, simply
reinstall the clip. This should only be used to prevent or react to accidents, and the operator is solely responsible for the decision.
COMMUNICATION
If you witness an emergency or become involved in one, you should request assistance via radio communication or visual signals. Review the information in Section 4 of the Sportfish, Cruisers, Yachts Owner’s Manual
for detailed information on how and when to request assistance.
RENDERING ASSISTANCE
Owners are required by law to render assistance to other boaters involved in an emergency situation such as
fire, collision, casualty, etc., as long as it does not endanger your vessel or its passengers.
REPORTING ACCIDENTS
Federal regulations require that operators involved in an accident file a written account of the situation within
48 hours. Reports should be submitted to the State Boating Law Administrator. You can obtain forms through
the USCG or local authorities (i.e. harbor patrol, sheriff or police offices). In the event that a casualty or disappearance occurs as the result of an accident, you must notify the authorities immediately by phone or radio and
fill out a written statement.
WEATHER
Pay attention to weather patterns. If you find yourself in the path of a storm, seek shelter im medi ately. 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.
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 attempt to tow a boat larger than your own. Be certain to use proper lines
(ropes) and rational judgement 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 information on towing, reference page 30 of the Sportfish, Cruisers, Yachts Owner’s Manual.

CARBON MONOXIDE (CO)
! DANGER
Carbon Monoxide (CO) is a colorless, odorless, and tasteless gas produced by the exhaust system of any
combustible engine. CO can cause brain damage or death, if inhaled over an extended period of time. To
protect yourself and your passengers, never block the ventilation outlets in cabins, consoles, or other
enclosed spaces.
One of the most important considerations when dealing with boating safety is carbon monoxide. Commonly
referred to as (CO), carbon monoxide is a colorless, odorless, and tasteless gas emitted from any engine exhaust.
Including inboards and outboards. A CO particle is close in weight to the air we consume; therefore it does not rise or
fall in the atmosphere, but accumulates in enclosed spaces. Boat owners with enclosed heads, cabins, or canvas enclosures should pay particular attention to CO. Be aware that fumes produced on your boat can affect other vessels and
other boats can affect you. A primary concern is the use of generators when boats are moored adjacent to each other.
Carbon Monoxide is poisonous and potentially fatal if inhaled over an extended period of time. Symptoms of CO
poisoning include:
• Dizziness
• Nausea / Vomiting
• Headache / Throbbing in the temples
• Fatigue
• Muscular twitching
• Inability to focus or think clearly
If you or any of passengers experience any of these symptoms, leave the area and find a source of fresh air immediately. If your symptoms persist, seek medical attention.

CHAPTER 2
PERFORMANCE
OVERVIEW
This chapter will provide information on the performance characteristics of your catamaran; This is
not a substitute for seamanship training or hands-on experience. First time boat owners should use the
resources detailed in Chapter 1 to learn proper methods of boat operation. Ex perienced boaters who have
never owned a catamaran, should study this chapter completely. Do not assume that previous boating experience will apply to all situations, as there are several subtle differences in the handling characteristics of
twin hulled boats. For existing catamaran owners, this chapter should be a reference.
MOTOR TRIM
The smooth riding characteristics of a catamaran are a result of the twin hull design. Their ability to
slice through oncoming waves is far superior to the slamming characteristics seen on conventional vessels.
Motor trim plays an integral part in how your catamaran accomplishes this. In a level or bow down attitude, your boat will slice through larger chop but you may experience sluggish performance, a wetter ride
and increased bow steering in a following sea. In a bow up attitude the boat will perform better, but may
ride less smoothly. Experiment with the trim settings in various sea conditions to determine what you are
most comfortable with. When using the trim to correct a listing condition, imagine an “X” connecting the
starboard engine to the port bow, and port engine to the starboard bow (see drawing below).
BOW UP CONDITION
To correct a bow up condition 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 setting on the starboard engine does not correct the list,
trim the port engine “up” to assist the change.
Reverse the instructions to accommodate for a bow
up condition on the starboard sponson.
BOW DOWN CONDITION
To correct a bow down condition 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 cavitation occurs on the starboard engine, lower it to correct the problem, then
trim the port engine “down” to assist the change.
Reverse the instructions to accommodate for a bow
down condition on the starboard sponson.

ENGINE CONTROLS
All factory rigged boats will come equipped with a binnacle, which controls the throttle, shift, and trim
mechanisms for your engine. For diagrams and general information about this system, review pages 70 and
71 of the Sportfish, Cruisers, Yachts Owner’s Manual. Also read the owner ’s manual provided by the bin-
nacle 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.
STEERING CONTROLS
Catamarans offer unsurpassed steering control. The wide spacing of the engines, advanced steering
components, and handling characteristics of the World Cat hull give operators exceptional maneuverability
in even the tightest spaces.
Because of the superior tracking abilities of the World Cat hull, oversteering can present a problem,
especially for owners accustomed to operating conventional boats. Conventional vessels have a tendency
to lose tracking abilities in rough and following sea conditions, making constant course corrections necessary. However, catamarans do not exhibit those traits and require operators to take a “hands off” approach.
To do so, relax your grip and fight the urge to make constant corrections.
STEERING MAINTENANCE
The design of a catamaran hull requires a special steering system which features a “liquid tie-bar”, as
opposed to the mechanical version used in conventional boats. For this reason, all World Cats are 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 characteristics 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 instructions:
1. Using the helm, center the starboard motor.
2. Find the steering system valve, located under the inspection port on the center of the transom.
3. Open the valve by rotating 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.
4. Center the port motor manually; then close the steering system ball valve and reinstall the
inspection 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 on
pages 4 thru 5, and the Teleflex™ owner’s manual in your “Owner’s Portfolio”. Use these resources, and
your dealer, to keep the steering system in excellent working order. Be aware, these are routine maintenance procedures and are not covered under warranty by World Cat.
! CAUTION
Routinely check hydraulic fluid levels, and all connections for leaks or any sign of mechanical fail-
ure. Lubricate all mechanical parts at least annually with high quality marine grease. Failure to
do so may result in impaired or unresponsive steering.
