CHAPTER 5: Safe Boat Operation

5.1 OPERATOR RESPONSIBILITIES

Ultimately, the boat operator is responsible for the safety and activity of all passengers. Additionally, the boat operator must respect other boaters and property. Before casting off, the operator should:

• Complete a pre-departure checklist to avoid emergencies later
• Ensure the vessel is cared for, is in good working order, and is seaworthy
• Ensure all passengers are properly seated and comfortable with the safety equipment and procedures in case of emergency
• File a float plan, particularly for lengthy trips or those in unfamiliar waters
• Check local hazards
• Check local weather forecast and conditions
• Life jackets are on

5.1.2 NO WAKE

"No wake" is defined as "The slowest possible speed required in order to maintain steerage and headway."

In the state of North Carolina PWCs are restricted to a slow-no wake speed when within 100 feet of the following:

• An anchored or moored vessel,
• A dock or pier,
• Swim float, marked swimming area, swimmers, surfers or persons engaged in angling,
• Any manually propelled vessel (ie, canoes and kayaks).

Note: This becomes 50 feet if operating in a narrow channel..

5.1.3 COURTESY

Other boaters and property owners wish to enjoy the water as well. As a courtesy to other boaters, swimmers and property owners, be sure to monitor your wake, noise level and boat speed around other boats and shoreline properties. You are responsible for any damage caused by your wake. Be sure to take the time to review proper safety and operation procedures if you let someone else operate your boat. Be particularly mindful of your boat noise in the early morning and late evening. Leave the water as you found it: clean up any waste you encounter and be sure to collect any of your own waste in a garbage bag and dispose of it properly once you get to shore.

5.1.4 SLACKEN SPEED

When operating a motorboat you must never be at a speed that is unreasonable and uncontrolled. The speed must be controlled so that you can avoid at all times any object or person on the water.

5.1.5 MUFFLERS AND NOISE LEVELS

In North Carolina recreational vessels that are equipped with an open-air exhaust engine that is capable of operating at greater than 4000RPM are required to have an effective means of muffling the exhaust sound level.

 

5.1.6 NEGLIGENCE

Any type of boating vessel demands an operator's respect and attention. Careless or reckless behavior aboard any vessel can result in dangerous consequences. A boat is not a toy. Enjoy your boating experience, but be mindful of the power of many vessels and the inherent dangers that water presents.

5.1.7 UNSAFE PRACTICES

The following acts and maneuvers are considered illegal while boating in North Carolina.

Careless Operation. It is illegal to operate a vessel in any way that endangers your ability to stay safe and not endanger rights or property of others. The following are a couple of examples.

• Endangering others or their property, such as allowing the wake of your vessel to harm another or their property or to even potentially do so.
• Jumping a vessel's wake while in close proximity to another vessel
• Failing to follow posted speeds, and signs which indicate restricted entry zones, diver or skier down flags, etc.

Operating at an unsafe speed. Boaters must always operate their vessel at a safe speed as they must also follow all indicated speed limitations

Failing to keep an adequate distance. Boaters must keep the designated no wake speed in certain circumstances as well as keeping their distance from water skiers or vessels towing someone on another device

Exceeding maximum capacity. The recommended capacity indicated on the boats capacity plate should never be exceeded.

Not maintaining a lookout. All vessel operators are required to keep a constant lookout for other vessels and/or people in the water.

Dangerous operation. Boaters must make sure that the vessel is being operated in a safe manner so that all its occupants or anyone sharing the water are not in any danger

Never permit underage operation of a boat.

5.1.8 HOMELAND SECURITY MEASURES

Federal, state and local governments have enacted specific measures since the events of September 11, 2001, to help deter unlawful or dangerous operations on our nation's waterways. Homeland Security Measures violations can result in severe consequences. Please be aware of the following Homeland Security Measures, and act accordingly to keep our waterways safe and secure:

• Do not approach closer than 100 yards from all military, cruise-line, or commercial shipping vessels.
• Slow to "no wake" speed within 500 yards of any large U.S. Navy vessel
• Observe and avoid all security zones.
• Avoid areas with military, cruise-line, or petroleum facilities.

FOR INFORMATION in port areas, you can call 1-800-682-1796, visit http://www.uscg.mil/safeports/, or check with local authorities.

• Observe other restricted areas near dams, power plants, etc.
• Do not stop or anchor beneath bridges or in channels.
• Report any suspicious activity immediately to local authorities, the U.S. Coast Guard, or marine security personnel, or call the National Response Center's Terrorist Hotline at 1-800-424-8802.
• Do not approach or challenge those acting in a suspicious manner, and never confront the suspicious party.
• Ensure your boat is always locked and secured when unattended, and always take the boat keys with you.

5.2 INFLUENCE OF DRUGS AND ALCOHOL ON BOAT OPERATION

5.2.1 DRIVE SOBER

Because of the fatiguing effects of the sun, wind and the motion of the boat, one drink on board is like three on shore! This means if you are drinking at all, then you should not be operating a boat or PWC. Do not jeopardize your safety or the safety of other boaters or the passengers in your care. Your balance, vision, coordination and judgment are all affected adversely by the consumption of even one alcoholic drink. Coupled with environmental elements (sun, glare, wind, motion), alcohol can have very serious consequences on the water. Please be responsible when operating your boat. If you are operating a vessel, you should avoid alcohol consumption.

5.2.2 SERIOUS PENALTIES

It is illegal for the boat operator to operate a vessel or be towed by a device (water-ski/tube/wakeboard), while intoxicated or under the influence of drugs.

In North Carolina, no person shall operate any motorized vessel, surfboard while under the influence of any impairing substance. They shall also not operate any motorized vessel after consuming alcohol sufficient to cause a blood alcohol concentration of 0.08% or greater.

 

5.3 CARBON MONOXIDE: PROTECT YOURSELF FROM THIS SILENT KILLER

Carbon monoxide can collect within, alongside or behind a boat in minutes and in a variety of ways.

5.3.1 AVOID THESE DEATH ZONES!

Do not swim near or under the back deck or swim platform. Carbon monoxide from exhaust pipes of inboard engines, outboard engines and generators build up inside and outside the boat in areas near exhaust vents. STAY AWAY from these exhaust vent areas and DO NOT swim in these areas when the motor or generator is operating.

On calm days, wait at least 15 minutes after the motor or generator has been shut off before entering these areas. NEVER enter an enclosed area under a swim platform where exhaust is vented, not even for a second. It only takes one or two breaths of the air in this "death chamber" for it to be fatal.

EXHAUST FUME DANGERS

Blockage of exhaust outlets can cause carbon monoxide to accumulate in the cabin and cockpit area—even when hatches, windows, portholes and doors are closed.

Exhaust from another vessel that is docked, beached, or anchored alongside your boat can emit poisonous carbon monoxide gas into the cabin and cockpit of your boat. Even with properly vented exhaust, your boat should be a minimum of 20 feet from the nearest boat that is running a generatoror engine.

Slow speeds or idling in the water can cause carbon monoxide gas to accumulate in the cabin, cockpit, bridge, and aft deck, even in an open area. A tailwind (force of wind entering from aft section of the motorboat) can also increase accumulation.

The "station wagon effect," or backdrafting, can cause carbon monoxide to accumulate inside the cabin, cockpit and bridge when the boat is operating at a high bow angle, with improper or heavy loading, or if there is an opening that draws in exhaust. This effect can also cause carbon monoxide to accumulate inside the cabin, cockpit, aft deck, and bridge when protective coverings are used and the boat is underway.

Teak surfing, dragging and water skiing within 20 feet of a moving watercraft can be fatal.

5.3.2 WHAT TO DO

• The best precaution against carbon monoxide poisoning is to keep air flowing through the vessel.
• Educate your passengers about carbon monoxide so they are aware of what the early poisoning signs are.
• If your boat has a rear-vented generator exhaust, check with the boat manufacturer for possible recall, or reroute the exhaust to a safe area.
• Assign an adult to watch when anyone is in the water.
• Schedule regular engine and exhaust system maintenance inspections by experienced and trained technicians.

• Keep forward-facing hatches open, even in inclement weather, to allow fresh air circulation in living spaces. When possible, run the boat so that prevailing winds will help dissipate the exhaust.

• Do not confuse carbon monoxide poisoning with seasickness, intoxication or heat stress.
• If someone aboard complains of irritated eyes, headache, nausea, weakness or dizziness, immediately move the person to fresh air, investigate the cause, and take corrective action. Seek medical attention, if necessary.
• Install a carbon monoxide detector in each accommodation space on your boat. Check detectors before each trip to be sure they are functioning properly. If the detector goes off, believe it!

5.3.3 FACTS ABOUT CARBON MONOXIDE

Carbon monoxide is a potentially deadly gas produced any time a carbon-based fuel, such as gasoline, propane, charcoal or oil, burns. Sources on your boat include gasoline engines, generators, cooking ranges, and space and water heaters. Cold or poorly tuned engines produce more carbon monoxide than warm, properly tuned engines.

Carbon monoxide is colorless, odorless and tasteless, and it mixes evenly with the air. It enters your bloodstream through the lungs and displaces the oxygen your body needs. Early symptoms of carbon monoxide poisoning— irritated eyes, headache, nausea, weakness and dizziness—are often confused with seasickness or intoxication. Prolonged exposure to low concentrations or very short exposure to high concentrations can lead to death.

Each year, boaters are injured or killed by carbon monoxide. Most incidents occur on older boats and within the cabin or other enclosed areas. Exhaust leaks, the leading cause of death by carbon monoxide, can allow carbon monoxide to migrate throughout the boat and into enclosed areas. New areas of concern are the rear deck near the swim platform with the generator or engines running, and teak surfing or dragging behind a slow-moving boat. Regular maintenance and proper boat operation can reduce the risk of injury from carbon monoxide.

5.3.4 PREVENTION CHECKLISTS

ALL CARBON MONOXIDE POISONINGS ARE PREVENTABLE!

CHECKLIST: EACH TRIP

• Educate all passengers about carbon monoxide poisoning.
• Make sure all exhaust clamps are in place and secure.
• Look for exhaust leaking from exhaust system components, indicated by rust and/or black streaking, water leaks, or corroded or cracked fittings.
• Inspect rubber exhaust hoses for burned or cracked sections. All rubber hoses should be pliable and free of kinks.
• Confirm that water flows from the exhaust outlet when the engine and generator are started.
• Listen for any change in exhaust sound that could indicate an exhaust component failure.
• Test the operation of each carbon monoxide detector by pressing the test button. Make sure the battery is installed properly and is in good condition. Never remove the battery unless you are replacing it with a new battery.
• Move seated passengers around the boat periodically to prevent any one from continuously being near any fumes.

CHECKLIST: AT LEAST ANNUALLY

• Replace exhaust hoses if you see any evidence of cracking, charring or deterioration.
• Inspect each water pump impeller and the water pump housing, and replace them if they are worn. Make sure cooling systems are in proper working condition to prevent overheating and possible burning of the exhaust system. (Refer to the engine and generator manuals for further information.)
• Inspect each of the metallic exhaust components for cracking, rusting, leaking or loosening. Pay particular attention to the cylinder head, exhaust manifold, water injection elbow, and threaded adapter nipple between the manifold and the elbow.
• Clean, inspect and confirm proper operation of the generator cooling water anti-siphon valve (if equipped).

THE ANNUAL CHECKLIST TEST MUST BE PERFORMED BY A QUALIFIED MARINE TECHNICIAN.

5.4 PROPELLER INTERVENTION AND AWARENESS

Rotating at great speeds and with a lot of power, the potential danger posed by boat engine propellers should not be overlooked. Each year hundreds of Americans accidentally come into contact with moving propeller blades. In 2006 alone, the US Coast Guard reported, 234 people struck by propellers with 28 fatalities.

Since the propeller is located below the waterline and may be difficult to see, it is important that people are at all times aware of the propeller. This is most important when in the water near the rear of a vessel or on the swim platform. As a precaution, operators should shut off the engine whenever a person is in the water within close proximity to their vessel.

Safety equipment is available and when used properly can significantly decrease the probability of a propeller strike. Common examples of equipment are:

• Propeller guards
• Ladder interlock kill switches
• Man over board cut-off switches
• Lanyard engine kill/stop switches
