Final answer:
A PWC without rudders will not turn when the throttle is released because it relies on jet propulsion for maneuvering, which requires water flow for effectiveness.
Step-by-step explanation:
A Personal Watercraft (PWC), without rudders, will not turn when the engine throttle is released. In such vehicles, turning is achieved through the propulsion system, which directs a jet of water for maneuvering.
If the throttle is released, the jet propulsion is minimized, and without the force to redirect the water, the craft will not turn effectively. Additionally, a PWC relies on the motion of water across its hull for stability, so turning ability is further compromised at low speeds or when stationary.
To turn a PWC effectively, operators must maintain some throttle to ensure water flow through the jet pump, which allows for steering even in the absence of rudders.
A PWC, or personal watercraft, without rudders will not turn when there is no force acting upon it to change its direction. In order for a PWC to turn, it requires a force to be applied in the desired direction.
This force can come from the rider leaning into the turn or from the thrust generated by the engine. Without any external force, the PWC will continue moving in a straight line.
