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 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 pro-
tects 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, Yachts 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. Registra-
tion 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.
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, ref-
erence 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.

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.
CAPACITY INFORMATION
On all boats under 26 feet in length, the manufacturer
is required to provide capacity information. If you own a
230 SF, 250 SF, or 250 DC you will find a rectangular
metal plate near the helm. This plate will provide informa-
tion 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 predeter-
mined, 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
Class Catamarans 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.
! CAUTION
Use only marine grade replacement parts. Most automotive and residential parts are not suitable for
use in the harsh marine environment. Using them could lead to premature product failure, property
damage, or personal injury.

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 pollution 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 compart-
ments 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 under-
way, or upon return to dock. Careful planning will add safety and pleasure to your experience and give you the confi-
dence 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 Sport-
fish, 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 inexperi-
enced operators.
• Ensure that all passengers are safely seated while underway, and are using the hand rails World Class has pro-
vided 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 accom-
plishing 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. 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.
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.
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 prob-
lem; 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.
! CAUTION
Never anchor your boat off the stern. The weight at the transom, combined with adverse sea condi-
tions could allow water to enter the boat over the transom wall.

EMERGENCY SITUATIONS
Unfortunately, even the safest boating practices cannot eliminate the potential of emergency situations develop-
ing. 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, Yachts Owner’s Manual provides information on emergency procedures. Below is important information
which all owners should be aware.
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 responsi-
ble for the decision.
COMMUNICATION
If you witness an emergency or become involved in one, you should request assistance via radio communica-
tion 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 disap-
pearance 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 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.
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 passen-
gers should remain clear of the lines to protect themselves from injury. For more information on towing, refer-
ence page 30 of the Sportfish, Cruisers, Yachts Owner’s Manual.

World Cat
1-7
CARBON MONOXIDE (CO)
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 enclo-
sures 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 imme-
diately. If your symptoms persist, seek medical attention.
! 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.

CHAPTER 2
PERFORMANCE
OVERVIEW
This chapter will provide information on the performance characteristics of your catamaran; This is not a substi-
tute 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.
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-
dition, 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 ves-
sel. 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 accom-
modate for a bow down condition on the starboard spon-
son.

World Cat
2-2
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 70 and 71 of the Sportfish, 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 equip-
ment.
STEERING CONTROLS
Catamarans offer unsurpassed steering control. The wide spacing of the engines, advanced steering components,
and handling characteristics of the World Class 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 abili-
ties 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 the 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 Class Catamarans.
! CAUTION
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.

STEERING SYSTEM - BLEEDING INSTRUCTIONS
Reference the bleeding instructions provided by the Teleflex™ owner’s manual, which is included in your
“Owner’s Portfolio”. Use them in conjunction with the instructions and diagram below to bleed the steering system.
This should be done annually.
STEP 1
1. Using a filler tube, fill the helm
with oil. When completed, you
should be able to see oil in the
filler tube.
2. Open the steering system valve
located under the inspection plate
in the center of the transom.
STEP 2
1. Open the bleed fitting labeled #1
and pull the cylinder shaft all the
way out on the fitting #1 side.
2. Holding the shaft to prevent it
from moving back into the cylin-
der, have someone turn the wheel
clockwise until a steady stream of
oil flows through the fitting.
3. Close bleed fitting #1.
STEP 3
1. Open the bleed fitting labeled #2.
and pull the cylinder shaft all the
way out on the fitting #2 side.
2. Holding the shaft to prevent it
from moving back into the cylin-
der, have someone turn the wheel counter-clockwise until a steady stream of oil flows through the fitting.
3. Close bleed fitting #2 and repeat Step 3 for bleed fittings #3 and #4.
STEP 4
1. When you complete the bleeding process, turn the wheel hard over in each direction at least twice. Then
manually adjust the cylinders by pulling the shaft all the way out on the same side of each cylinder and clos-
ing the steering system valve.
NOTICE
If possible, have your dealer or trained marine technician perform routine maintenance or repairs on
your steering system. Replace faulty parts immediately.

HANDLING CHARACTERISTICS
World Class Catamaran’s patented Vectroflo™ hull is a semi-displacement hull, which exhibits characteristics
of both planing and displacement hulls. Planing hulls provide speed and economy of operation since a limited amount
of the hull is in contact with the water. However, they feature flat sections along the chine which can result in poor
handling at low speeds and harder impacts at high speed. Displacement hulls provide superior handling characteris-
tics, even at low speed, and an improved ride in rough water. Speed and economy suffer however, since more of the
hull is submerged. World Class has taken the best characteristics of these two designs and incorporated them in the
Vectroflo™ hull. Our proven design provides a superior ride, excellent handling characteristics in a variety of condi-
tions, and speed with economy of operation. To help you experience “The Ultimate Ride”, study the following sec-
tions.
TURNING CHARACTERISTICS
Turning a catamaran is slightly different than cornering on a conventional vessel. Imagine the difference
between an automobile and a motorcycle. Automobiles take turns in a flatter, more stable, manner similar to
catamarans hulls, while motorcycles pitch hard into a turn similar to a monohull. Do not underestimate a cata-
maran’s cornering ability however, hard adjustments to the steering wheel can make a World Cat bite quickly
and execute high performance turns. Experiment with the handling ability of your cat so you are prepared for
any situation on the water.
ADVERSE SEA CONDITIONS
Catamarans are designed to handle some of the roughest waters in the world, but that is no substitute for com-
mon sense. As an operator you are responsible for the safety of your passengers and vessel; therefore, your
trips should be limited by your level of experience. Planning and paying constant attention to the weather and
sea conditions is paramount. If you are forced to operate in dangerous seas however, you can be confident that
your World Cat, when operated properly, can handle them safely. Following are some tips on how to handle
your boat in adverse sea conditions.
• When traveling into the wind, changing your direction a few degrees to allow one sponson to settle
before the other, can make the ride smoother and allow for increased speed.
• In a rough chop with short wave intervals, increasing your speed may allow the boat to skim across
the tops of each wave. This will result in a smoother ride.
• Steer to avoid larger swells and breaking waves.
• In a following sea, position your vessel on the back of a wave and match its speed to remain ahead of
the trough. Speed is paramount. Work the throttle to avoid going over the wave or being thrown
down the face of a following wave.
• When entering an inlet, use the same method of matching wave speeds. Often there are breakers in
an inlet so be aware of shallow water conditions.

BOATING TIPS
Experience is the best way to determine the handling characteristics of your catamaran. Operating the boat in
multiple sea conditions and under various loads will help you predict how the boat will perform in any situation.
World Cat provides the following recommendations regarding the performance of your catamaran:
• Establish an RPM chart which details the speed and fuel consumption at various RPM levels to
achieve the most economical operation.
• Monitor fuel gauges to determine the amount of operating time remaining at a given reading.
• Determine minimum speed for effective steering in close quarters.
• Determine the turning radius required at various speeds.
• Determine the rates of acceleration and deceleration with various load conditions. Include the dis-
tance required to stop the boat at various speeds.
Use the information provided in section 6 of the Sportfish, Cruisers, Yachts Owner’s Manual for more informa-
tion on boat handling.
PERFORMANCE FACTORS
Proper setup and maintenance of the systems on your boat is important to ensuring proper performance, but be
aware they are not the only factors which affect it. Several things which contribute to the level of performance of your
catamaran can change between or during trips.
ENGINE EFFICIENCY
Without proper maintenance, your engine(s) will gradually lose power, resulting in a loss of speed. Use the
recommendations in the engine’s owners manual to schedule routine maintenance procedures and as a guide
for the correct RPM range for your engines. Neglecting to do so may result in loss of performance and an
increased risk of failure.
PROPELLER CONDITION
The size and condition of your prop also plays a major role in the performance of your catamaran. A damaged
prop can result in lower speeds, sudden drops in RPM, increased fuel consumption, and severe vibration while
running. Improperly sized props can cause damage to your engine as a result of exceeding the maximum or
minimum RPM levels.
WEATHER CONDITIONS
Barometric pressure and humidity can affect the output of your engines. For example, on an extremely hot and
humid day, your engine can experience as much as a 10 percent loss in horsepower. Although you should mon-
itor your engines’ performance, be aware that the weather could be a major factor in your boats performance.

LOAD
Increased load can obviously affect performance, especially if the load is unbalanced. Passengers, gear, and
fuel are all examples of things which can affect your vessel. Fuel levels change through the day, and greatly
affect the attitude of your boat. When necessary, make adjustments to engine trim and load distribution to
compensate for fuel usage.
MARINE GROWTH
If you store your boat in the water or fail to clean it after each trip, the existence of marine growth can contrib-
ute to a loss of performance. A decline in speed or increased fuel consumption can occur. Prevent this by
applying a marine growth inhibitor or by cleaning your boat thoroughly after each trip.
BOTTOM PAINT
Bottom painting your catamaran will also change the performance. Although not significant, you can expect a
drop in speed between 1 and 5 miles per hour.
