Study Notes
Jet Stream Injuries
- Jet streams from personal watercraft (PWC) can cause serious internal injuries, permanent disabilities, or death by forcing water into the body's cavities.
- To prevent jet stream injuries, operators must connect the engine cut-off switch lanyard to their wrist or personal flotation device (PFD) to shut off the engine if they fall in the water.
- Wearing wetsuits or protective clothing is recommended for operators and passengers to minimize the risk of injury from the jet stream.
Propeller Injuries
- Propeller strike accidents are among the most gruesome boating incidents, posing risks to swimmers, divers, and individuals who have fallen overboard.
- The primary causes of propeller strikes include operator inexperience, negligence, and intoxication; many can be avoided by adhering to safety practices.
- Operators should turn off the engine while passengers are boarding or disembarking to prevent injuries when they are in vulnerable positions.
Preventative Measures for Propeller Strikes
- Avoid accidentally throwing passengers overboard by ensuring all individuals are safely seated before departure.
- Maintain a proper lookout for individuals in the water by slowing down in congested areas and being alert to swimmers and divers.
- Familiarity with warning buoys and flags indicating diver presence is crucial for safe navigation.
Personal Flotation Devices (PFDs)
- A PFD not only keeps individuals afloat but also enhances visibility to assist boaters in spotting them in the water.
Technologies to Reduce Propeller Strikes
- New technologies aimed at reducing propeller-related accidents include:
- Guards: Devices creating barriers around the propeller, such as deflection devices and ring guards.
- Propulsion Systems: Alternatives to traditional propellers, including jet drives and pump jets.
- Interlocks: Automatic systems that turn off the engine or trigger alarms when specific conditions are met, such as using a ladder.
- Sensors: Wireless devices worn by boaters that disable the boat's engine or trigger alarms if the wearer falls overboard.
Steering Torque Hazards
- Serious injuries and fatalities can occur due to steering torque when operators let go of the steering wheel or handle while the boat is in motion.
- This phenomenon causes the boat to swerve sharply, leading to potential strikes from the propeller as the boat circles back to the victim, creating a situation known as the "circle of death."
- To prevent accidents, operators should keep a firm grip on the steering until the boat has completely stopped and utilize automatic shut-off lanyards if available.
