Final answer:
It's illegal to operate a small motorboat at more than a slow no wake speed in a designated swimming area for the safety of swimmers.
Step-by-step explanation:
It is illegal to operate a motorboat less than 20 feet in length at greater than slow no wake speed while in a designated swimming area (Option C). The reason behind this law is to protect the safety of swimmers from the dangers posed by moving boats and their wakes.
Operating a motorboat at a slow no wake speed ensures that the movement of the boat does not create a significant wave or wake that could harm swimmers or disrupt the swimming area.
Operating a motorboat less than 20 feet in length at greater than slow no wake is illegal when it is done in a designated swimming area. This is to ensure the safety of swimmers and prevent accidents or injuries.
For example, if there is a specified area for swimming in a lake or river, it is important to operate your motorboat at slow no wake speed to avoid endangering swimmers in that area.
