4.2 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 is required. Some areas require permits or temporary registra-
tions 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 well as, communicating with your dealer and our ser-
vice department. Including this information in any correspondence or conversations will help our support network
serve you better.

in the harsh marine environment. Using them could lead to premature product failure, property damage,
or personal injury.
4.4.1 Capacity Information
On all boats under 26 feet in length, the manufacturer is required to provide
capacity information. If you own a model under 26 feet in length 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.
This label means your World Cat is certified by the NMMA. With this tag, you are assured
your fuel system, electrical system, lighting, ventilation, and steering are not only in
compliance with the US Coast Guard regulations, but also meet the more stringent standards
of the NMMA. The NMMA is a national trade organization serving all elements of the
recreational boating industry including manufacturers of boating equipment. With this tag,
you can have confidence in the safety of your boat.

Horsepower ratings, however, are set by World Cats and
should not be exceeded. The second page in Section 10.2
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.
4.5 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

2015 World Cat 255DC Owners Manual
Page 4-14
pamphlet and understand any local regulations regarding pollution control. As the operator, you are also liable for
individuals on your vessel disposing of materials in an improper manner.
4.5.1 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:

and should be displayed in an area visible during normal
operation. They can be purchased from your dealer or
marine equipment suppliers.
4.6 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:
4.6.1 Pre-Departure
xEstablish 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.
xIf 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.
xIf you are towing the boat, inspect the trailer including tires, lights, brakes, winch, and overall mechanical
appearance. 6SRUWILVK&UXLVHUV<DFKWV2ZQHU¶V0DQXDOSDJH
xVerify 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.
xCheck fuel levels and determine if you require additional fuel for your trip.
xExamine 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
xPrepare your boat prior to backing down, (i.e. secure all lose items, install garboard drain), then launch your
vessel and move away quickly.
xMove your vessel away from the dock and complete a full system check. Ensure that electronics, pumps, and
safety equipment are in working order.
xInstruct 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.

ILVK&UXLVHUV<DFKWV2ZQHU¶V0DQXDOto understand right of way and the various navigational and hazard
indicators you will see on the water.
xNever operate a boat under the influence of alcohol or drugs.
xDo not allow individuals under the age of 16 to operate the vessel. Maintain direct supervision of inexperi-
enced operators.
xEnsure that all passengers are safely seated while underway, and are using the hand rails World Cat has pro-
vided to remain securely in their seats.
xUse 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 22 of the Sportfish, Cruisers, Yachts
2ZQHU¶V0DQXDOfor more tips on weather.
xMaintain a saIHVSHHGDQGUHVSHFWRWKHUERDWHUVDVZHOODVWKRVHRQODQG2EH\DOO³1R:DNH=RQHV´DQGEH
aware of smaller vessels. The wake you produce could endanger other crafts and their passengers.
xKnow 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.
4.6.4 Returning
xObey navigational markers and be aware of any tidal changes since departure.
xCollect and dispose of refuse properly to maintain our waters for future generations.
xPrepare 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.
xVerify that trailer systems are working properly and all items are secured before leaving.
xWash the boat and perform general maintenance, upon returning home. (See instructions in Chapter 5).
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 accom-
plishing this, see the example on pages 44 & 45 of the 6SRUWILVK&UXLVHUV<DFKWV2ZQHU¶V0DQXDO
4.7 TRAILERING
Due to the nature of the hull, catamarans require specialized trailers. Your 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.

2015 World Cat 255DC Owners Manual
Page 4-16
4.8 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 56 of the
6SRUWILVK&UXLVHUV<DFKWV2ZQHU¶V0DQXDOfor more information and tips concerning anchoring.
!
!! !! ! C CA AU UT TI IO ON N
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.
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 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 this will solve the problem;
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.
4.10 EMERGENCY SITUATIONS
Unfortunately, even the safest boating practices cannot eliminate the potential of emergency situations developing.
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 them 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,
<DFKWV2ZQHU¶V0DQXDOprovides information on emergency procedures. Below is important information 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 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, turn ignition switches to the off
position, return binnacle to neutral position insert safety lanyard back into clip and then turn ignition 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 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 6SRUWILVK&UXLVHUV<DFKWV2ZQHU¶V0DQXDOfor detailed
information 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 situation such as fire,
collision, casualty, etc., as long as it does not endanger your vessel or its passengers.

2015 World Cat 255DC Owners Manual
Page 4-17
4.10.4 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.
4.10.5 Weather
Pay attention to weather patterns. If you find 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 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 39 of the
Sportfish, Cruisers, Yachts 2ZQHU¶V0DQXDO
4.11 CARBON MONOXIDE (CO)
!
!! !! ! D DA AN NG GE ER R
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:
xDizziness
xNausea / Vomiting
xHeadache / Throbbing in the temples
xFatigue
xMuscular twitching
xInability 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 imme-
diately. If your symptoms persist, seek medical attention.

Chapter 5: PERFORMANCE
5.1 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. Experienced 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.
5.2 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 con-

5.3 ENGINE CONTROLS
All factory rigged boats will come equipped with a binnacle control specific to your type of engine. Located at the
helm, the binnacle controls the throttle, shift, and trim mechanisms for your engine. For diagrams and general
information about this system, review pages 80 thru 83 of the 6SRUWILVK&UXLVHUV<DFKWV2ZQHU¶V0DQXDOAlso read

If any components of this system need to be replaced, be certain to use the same style and length as the original equip-
ment.
5.4 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

mechanical version used in conventional boats. For this reason, World Cat 255DC 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 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 in section 5.6 thru 5.7

Routinely check hydraulic fluid levels, and all connections 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.
