What is the risk when a PWC passes too closely behind the other boat?

When a personal watercraft (PWC) passes too closely behind another boat, there is a significant risk of collision due to the reduced visibility and potential for the PWC to be caught in the wake generated by the larger vessel. The wake can create sudden changes in water conditions, leading to instability and loss of control for the operator. Additionally, the proximity may prevent the operator from reacting in time to avoid obstacles or other hazards. This behavior can also pose a danger to passengers and other watercraft in the vicinity.
