A boat with three inch high railings where my passengers legally ride?

A boat with three-inch high railings is generally considered to have a low level of safety, as these railings may not adequately prevent passengers from accidentally falling overboard. Depending on local regulations and safety standards, it may be required to have higher railings or other safety measures. Passengers should always be advised to exercise caution while on board, especially if the boat is in motion or in rough waters. It's important to ensure compliance with maritime safety regulations to protect all passengers.
