Boating Experience
If this is your first boat or if you are changing to a type of boat you are not familiar with, for your own comfort and
safety, obtain handling and operating experience before assuming command of the boat.
Take one of the boating safety classes offered by the U.S. Power Squadrons or the U.S. Coast Guard Auxiliary. For
more course information, including dates and locations of upcoming classes, contact the organizations directly:
•U.S. Power Squadrons: 1-888-FOR-USPS (1-888-367-8777) or on the Internet at: http://www.usps.org
•U.S. Coast Guard Auxiliary: 1-800-368-5647 or on the Internet at: http://www.cgaux.org
Outside the United States, your selling dealer, national sailing federation or local boat club can advise you of local
sea schools or competent instructors.
Safety Standards
Your boat’s mechanical and electrical systems were designed to meet safety standards in effect at the time it was
built. Some of these standards were mandated by law, all of them were designed to insure your safety, and the safety
of other people, vessels and property.
In addition to this owner’s manual supplement, please read the Cruiser & Yacht Owner’s Manual and all acces-
sory instructions for important safety standards and hazard information.
Engine & Accessories Guidelines
Your boat’s engine and accessories were selected to provide optimum performance and service. Installing a different
engine or other accessories may cause unwanted handling characteristics. Should you choose to install a different
engine or to add accessories that will affect the boat’s running trim, have an experienced marine technician perform a
safety inspection and handling test before operating your boat again.
Certain modifications to your boat can result in cancellation of your warranty protection. Always check with
your dealer before making any modifications to your boat.
The engine and accessories installed on your boat come with their own operation and maintenance manuals. Read
and understand these manuals before using the engine and accessories.
CONTROL HAZARD! A qualified operator must be in control of the boat at all times. DO NOT
operate your boat while under the influence of alcohol or drugs.
WARNING!
!
DANGER
PERSONAL SAFETY HAZARD! DO NOT allow anyone to ride on parts of the
boat not designated for such use. Sitting on seat backs, lounging on the forward
deck, bow riding, gunwale riding or occupying the transom platform while
underway is especially hazardous and will cause personal injury or death.
DANGER!
!
DANGER
PERSONAL SAFETY HAZARD! ALWAYS secure the anchor and other loose objects before get-
ting underway. The anchor and other items that are not properly secured can come loose when
the boat is moving and cause personal injury or death.
DANGER!
!
NOTICE
When storing your boat please refer to your engine’s operation and maintenance manuals.

CHAPTER 1: WELCOME ABOARD! 3
Qualified Maintenance
Failure to maintain your boat’s systems (listed in the warning above) as designed could violate the laws in your juris-
diction and could expose you and other people to the danger of bodily injury or accidental death. Follow the instruc-
tions provided in the Cruiser & Yacht Owner’s Manual, this Owner’s Manual Supplement, the engine owner’s manual
and all accessory instruction sheets and manuals included in your owner’s packet.
Structural Limitations
The transom platform and bow platform are designed to be lightweight for proper boat balance. The load limit for
these platforms is 30 pounds per square foot, evenly distributed.
Special Care For Moored Boats
Whether moored in saltwater or freshwater, your boat will collect marine growth on its hull bottom. This will detract
from the boat’s beauty, greatly affect its performance and may damage the gelcoat. There are two methods of slowing
marine growth:
•Periodically haul the boat out of the water and scrub the hull bottom with a bristle brush and a solution of soap
and water.
•The hull below the waterline may have anti-fouling paint applied by the factory. Occasionally you will need to re-
paint it with a good grade of anti-fouling paint.
Sacrificial Anodes (Zincs)
Your boat is equipped with sacrificial anodes (zincs) to protect underwater metal parts from excessive deterioration.
Check the zincs regularly and replace them if they have deteriorated more than 70%.
There are many factors that affect the rate at which the zincs deteriorate, including:
•Water temperature
•Salinity
•Water pollution
Stray electrical current from the boat or dock may cause complete deterioration in just a few weeks. If there is rapid
zinc deterioration, measure the electrolytic corrosion around your boat with a Corrosion Test Meter. If the zincs are
not bonded correctly, they will not provide protection.
To maintain the integrity and safety of your boat, allow only qualified personnel to perform
maintenance on, or in any way modify: The steering system, propulsion system, engine control
system, fuel system, environmental control system, electrical system or navigational system.
WARNING!
!
NOTICE
•To help seal the hull bottom and reduce the possibility of gelcoat blistering on moored boats,
apply an epoxy barrier coating, such as INTERLUX, Interprotect 2000E/2001E. The barrier
coating should be covered with several coats of anti-fouling paint.
•Many states regulate the chemical content of bottom paints in order to meet environmental
standards. Check with your local dealer about recommended bottom paints, and about the
laws in effect in your area.
Do not paint between the zinc and the metal surface it contacts and do not paint over the zincs.
NOTICE

4 CHAPTER 1: WELCOME ABOARD!
Carbon Monoxide (CO)
•CO poisoning causes a significant number of boating deaths each year.
•Called the "silent killer", CO is an extremely toxic, colorless, odorless and tasteless gas.
•Breathing CO blocks the ability of your blood to carry oxygen.
•The effects are cumulative, even low levels of exposure can result in injury or death.
Factors increasing the effects of CO poisoning include:
•Age
•Smokers or people exposed to high concentrations of cigarette smoke
•Consumption of alcohol
•Lung disorders
•Heart problems
•Pregnancy
DANGER
CARBONMONOXIDEPOISONING HAZARD!
Carbon monoxide gas (CO) is colorless, odorless, and extremely dangerous. All
engines, and fuel burning appliances produce CO as exhaust. Direct and prolonged
exposure to CO will cause BRAIN DAMAGE or DEATH.
Signs of CO poisoning include:
•Headache
•Nausea
•Dizziness
•Drowsiness
DANGER!
!

CHAPTER 1: WELCOME ABOARD! 5
Sources of CO
Sources of CO include:
To correct stationary situations (a) and/or (b):
•Close all of the windows, portlights and hatches.
•If possible, move your boat away from the source of the CO.
To correct running situations (c) and/or (d):
•Trim the bow down.
•Open the windows and canvas.
•When possible, run the boat so that the prevailing winds will help dissipate the engine exhaust.
Immediately take corrective action if CO is detected or suspected (see, Carbon Monoxide Alarm System, below).
Carbon Monoxide Alarm System
•Your boat features a carbon monoxide (CO) alarm system.
•Do not disconnect the alarm system.
•Read and understand the manufacturer’s instructions for your CO alarm system. If you did not receive an instruc-
tion manual, call [phone] and one will be mailed to you.
•If your boat is not equipped with a carbon monoxide alarm, consider purchasing one from your dealer or marine
supply store.
What To Do If Carbon Monoxide Is Detected
•Immediately ventilate and evacuate any enclosed spaces that are occupied by people and reset your CO alarm.
•Immediately move anyone showing any symptoms of CO poisoning into fresh air.
•See a doctor if any symptoms persist. If the person is unconscious, immediately administer oxygen or CPR and
call for emergency help.
c. Running boat with
trim angle of bow
too high.
a. Using engine or generator
when boat is moored in a
confined space.
b. Mooring close to
another boat that
is using its engine,
generator or any
other CO source.
d. Running boat with-
out through ventila-
tion (station wagon
effect).
