Which type of life jacket is least appropriate for an unconscious person in the water?
Answer: Type III (flotation aid), because it may not turn an unconscious wearer face-up
Type III life jackets are designed for conscious wearers in calm water — they do not reliably turn an unconscious person face-up, unlike Type I or II.
What should a PWC operator do before making a sharp turn at high speed?
Answer: Reduce speed significantly, as PWCs lose steering if the throttle is released mid-turn
Most PWCs use jet thrust for steering, so releasing the throttle during a turn removes all steering authority and the craft will not turn.
What is the purpose of a kill switch (engine cut-off switch) on a boat or PWC?
Answer: To automatically shut off the engine if the operator falls overboard or leaves the helm
The kill switch lanyard attaches to the operator's wrist or life jacket; if the operator is ejected, the lanyard pulls free and kills the engine.
Why is surfing or sitting on the bow, gunwale, or transom of a moving boat dangerous?
Answer: The person can fall overboard and be struck by the propeller or the hull
Riding exposed on the exterior of a moving vessel is called 'bowriding' or 'gunwale riding' — a fall into the propeller arc is often fatal.
When inflating a tube or towable for towing, what is the most important safety check before towing guests?
Answer: Ensure all riders are wearing properly fitted Coast Guard-approved life jackets
Wearing a properly fitted life jacket is the single most critical safety requirement before any towed water sports activity begins.
What is the safe distance a PWC must maintain from another vessel, swimmer, or object when operating at speed?
Answer: At least 100 feet from swimmers and other vessels
The general 100-foot rule applies to PWCs when operating near swimmers, other boats, and fixed objects to allow adequate reaction and stopping distance.
