At what times of day is towing a water skier generally prohibited under US boating regulations?
Answer: From one hour after sunset to one hour before sunrise
Most states prohibit towing water skiers during low-light periods — typically one hour after sunset until one hour before sunrise.
What should a PWC (personal watercraft) operator do if they fall off?
Answer: Reboard from the rear of the PWC as indicated by the boarding label
The boarding label on the stern indicates the correct reboarding direction, which varies by model — always check your specific PWC.
Which of the following is a common cause of propeller strike injuries during water sports?
Answer: Starting the engine before the swimmer or skier is fully clear of the water and propeller
Most propeller strike injuries happen when the engine is started or the boat is put in gear before confirming all people are clear of the propeller.
What is the recommended action if a tow rope becomes wrapped around the propeller?
Answer: Shut off the engine completely before attempting to remove the rope
The engine must be completely shut off to eliminate all risk of the propeller suddenly engaging while someone clears the rope.
How should a boat operator pick up a fallen water skier?
Answer: Circle back with the skier on the operator's side so the skier remains in view
Approaching with the skier on the operator's side ensures continuous visual contact and reduces the risk of the skier being struck by the hull or propeller.
What does a boat displaying an orange or red flag (alpha flag) near towed water sports activities indicate?
Answer: A skier is down in the water and nearby boats should reduce speed and stay clear
An orange skier-down flag signals that a person is in the water and approaching vessels must slow down and steer well clear.
