Chapter 2: Safety
MINIMUM REQUIRED SAFETY EQUIPMENT
The US Coast Guard (USCG) requires that every boat have specific equipment on board.
Check with local regulations on mandatory equipment apart from the list of Coast Guard
requirements. See Sportfish, Cruisers, Yachts Owner’s Manual, page 23, for details on the
following minimum required safety equipment.
•FireExtinguisher
Boats should be equipped with a marine approved fire extinguisher.
• Personal Flotation
All passengers must have an USCG approved personal flotation device (PFD).
Children and non-swimmers are advised to wear a PFD at all times.
• Sound Signaling Device (Horn, Bell Or Whistle)
Your Grady-White is equipped with a horn that meets USCG requirements.
• Visual Distress Signals
USCG approved visual distress signals are required on U. S. waters. See page 42 of the
pamphlet Sportfish, Cruisers, Yachts Owner’s Manual enclosed with this manual for more
information.
• Lighting
Grady-White boats are equipped with navigational lights that meet requirements for
recreational vessels for inland and international waters.
ADDITIONAL RECOMMENDED EQUIPMENT
In addition to the required safety equipment, there are additional items that will provide an
extra margin of safety and convenience for you and your passengers while boating. For an
extended list of basic gear, tools and spare parts, reference page 24 of the pamphlet Sportfish,
Cruisers, Yachts Owner’s Manual enclosed with this manual.
Keep tools and spare parts in good condition. Replace parts removed from the spare parts kit.
Most importantly, use US Coast Guard approved or marine certified parts where applicable.
Conditions found requiring corrective action should be worked on by a qualified repairman.
REGISTRATION NUMBERS
Federal and State laws require a powerboat to be registered in the State where it is primarily
used. Registration numbers and validation stickers must be displayed according to regulations.
The registration certificate must be on board when boating. The boat serial number or Hull
Identification Number (HIN, page 1–2) is required on the registration form. The HIN is located
on the upper right hand corner of the transom, and is the most important identifying factor. The
HIN should be included in all documents and correspondence to provide you timely service.

SAFETY
2–2
EMERGENCY STOP SWITCH
All Grady-Whites are equipped with an emergency stop switch. This is a safety feature that if
used properly will shut the engine(s) down if the operator leaves or falls from the helm position.
The ignition shutdown system includes a shut-off switch, switch clip, lanyard and lanyard clip.
The lanyard clip is attached to the operator. If a situation arises where the boat should stop, a pull
on the cord to release the clip from the shut-off switch will shut down the engine(s). To reset the
emergency stop switch, simply reinstall the switch clip. The decision to use the emergency stop
switch rests with the owner/operator. See page 82 in Sportfish, Cruisers, Yachts Owner’s Manual.
EMERGENCY INFORMATION
While boating, unpleasant situations may develop. You should prepare yourself on how to
cope with them whether they happen aboard your vessel or someone else’s. Anticipate and plan
for specific situations such as fire, man overboard, collision, etc. to give you the confidence and
ability necessary to handle an emergency. The key is to remain calm. For emergency procedures,
see Section 4 in Sportfish, Cruisers, Yachts Owner’s Manual.
• Rendering Assistance
The owner or operator of a vessel is required by law to render all practical or necessary
assistance to any person or vessel affected by collision, accident or casualty. However, you
are not required to endanger your vessel or passengers to render assistance.
• Accident Reporting
Report all boating accidents to your local authorities. Federal regulations require boat
operators involved in an accident to submit a written report within 48 hours. In the event of
death or disappearance, notification is required immediately by phone or radio in addition
to the written report. These reports can be submitted to the State Boating Law Administrator.
Forms can be obtained through the USCG, local harbor patrol offices, sheriff, and police
stations.
• Lightning Precautions
This awareness is included to ensure the safety of the owner and passengers. Always be
mindful of the weather! When a lightning storm advances, certain safety precautions should
be taken. Dock the boat and seek shelter on land. If this is not possible, seek refuge inside the
boat until the storm has passed. Stay out of the water! Lightning will seek a ground when it
strikes and may pass through metal components if it hits your boat. For this reason, avoid
contact with metal parts of the boat under these conditions.

BOATING SAFETY TIPS
Safety is an important aspect of boating. Your safety as well as the safety of your passengers
and vessel is your responsibility. The following precautions and the ones mentioned in section 1
of Sportfish, Cruisers, Yachts Owner’s Manual will add to you and your passengers’ boating
safety and pleasure.
• Before operating your Grady-White read and study all operation and maintenance
manuals. It is important that you fully understand how to use your boat. Contact your Grady-
White dealer for questions. Proper use and service will insure quality performance and
longevity of your boat.
• A written float plan left with a responsible person can serve as valuable information should
you not return as scheduled. Upon returning, your primary responsibility is to notify the person
of your return.
•Never operate or allow anyone to operate your boat while under the influence of drugs or
alcohol.
• Individuals under the age of 16 should not be allowed to operate your boat.
Inexperienced drivers should have constant and direct supervision.
• Instruct at least one passenger on the fundamentals of basic boating and safe operation in the
event of an emergency.
• While boating, passengers should be settled in a safe position. Use hand holds and rails for
steadiness. Do not allow bow, transom or gunwale riding. The captain is ultimately responsible
for their passenger’s safety.
• Keep your boat speed under control. Respect for other boaters and those on shore are common
courtesies. The boat’s operator is responsible for injury or damage caused by the boat or the
wake. Your wake could swamp a smaller craft and endanger its passengers. Stay alert for
posted “No Wake Zones”.
• Become familiar with the handling personality and limitations of your boat.
•Never allow swimmers/skiers to enter or exit the boat with engine(s) running. A shift lever
in neutral could become engaged accidentally. Also, exhaust fumes from the outboard
engine(s) contain carbon monoxide gas. These fumes may concentrate in this area. See more
information on “Carbon Monoxide” on page 2–5
• Obtain information and a chart for new areas when possible.
• Clean water and air are responsibilities for all persons. Use litter containers on board and
dispose of refuse properly. See “Pollution Regulations” on page 3–2.
• Know and obey the “Rules of the Road”. See Sportfish, Cruisers, Yachts Owner’s Manual,
beginning on page 25, for a better understanding of right of ways, signals and waterway
markers.

CERTIFICATION
This label means your Grady-White is certified by the
National Marine Manufacturers Association (NMMA).
With this tag, you are assured the fuel system, electrical
system, navigation lighting, ventilation, steering and other
design elements 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.
This label means that Grady-White has designed and built your boat to the ABYC standard H-
8, buoyancy in the event of swamping. Basic flotation is defined as having enough foam in the
boat to create buoyancy and prevent sinking under swamped conditions.
BASIC FLOTATION
THIS BOAT HAS "BASIC FLOTATION" AS
DEFINED BY ABYC STANDARD H-8.

SAFETY
2–5
LOADING CAPACITY
Though overloading is a primary cause of many boating accidents, improper loading is
equally hazardous. Boaters should know the amount of weight on board and evenly distribute the
weight within the boat.
At the helm station you will find a NMMA Yacht Certification tag. This means your yacht
complies with the Coast Guard safety standards. (NOTE: Any boat with an overall length of 26
feet or greater is defined as a “yacht” by NMMA.
CARBON MONOXIDE
Carbon Monoxide, commonly written CO, is a colorless, odorless gas emitted from any boat’s
exhaust. The gas is similar in weight to the air we breathe. Therefore, it cannot be expected to rise
or fall, but will accumulate in confined spaces.
W A R N I N G
CO is produced by all combustion engine(s) and generator sets.
Avoid brain damage or death from carbon monoxide.
Keep cockpit and cabin areas well ventilated.
Avoid blockage of exhaust outlets.
Signs of exposure include headache, nausea, dizziness and drowsiness.

Carbon monoxide is poisonous, and potentially fatal if breathed over an extended period of
time. Symptoms of CO poisoning include dizziness, nausea, headache, sleepiness, vomiting,
throbbing in the temples, muscular twitching, and an inability to think clearly. If you or anyone
else experience these symptoms, immediately get away from fumes and into an area where
plenty of fresh air can be consumed. If any symptoms from above persist, seek medical
attention.
Carbon monoxide can accumulate in cabins and under canvas. If your boat is equipped
with a canvas that encloses the aft cockpit and propulsion equipment, do not operate the boat with
this canvas closed.
Outboard engine exhaust fumes contain carbon monoxide. These fumes may concentrate at
the motorwell area. Do not board your vessel with the engine(s) running. Also, do not occupy the
motorwell area with the engine(s) running.
Operators need to be aware of the influence of other boats on their vessel as well as the effects
they have on neighboring crafts. Of primary concern is the operation of an auxiliary generator
with boats moored along side each other. This situation creates an atmosphere which is filled with
CO, and extremely dangerous.
If your CO monitor alarm sounds, indicating CO is present, immediately remove yourself
from the area and go to a location with fresh air. Shut off sources of CO such as engines and
generators and open doors and windows to ventilate the affected area if possible. If you or anyone
aboard your vessel experiences persistent symptoms of CO poisoning seek medical attention right
away.
W A R N I N G
BE AWARE of the significance your exhaust may have on other vessels. Likewise, BE AWARE
that the operation of other vessel's equipment may influence the carbon monoxide concentration
on YOUR vessel.
W A R N I N G
Exhaust fumes from engine(s) contain (CO). Boats with canvas deployed are more likely to collect
exhaust fumes. Avoid brain damage or death from (CO). Keep cockpit and cabin areas well
ventilated. Signs of exposure include headache, nausea, dizziness and drowsiness.
