Final answer:
It is illegal to attach your vessel to a lateral buoy or non-lateral marker. These navigation aids are not meant for mooring as it can compromise navigation safety. Mooring buoys, piers, and fueling docks, when appropriate, can usually be used for tying up vessels.
Step-by-step explanation:
To which of the following is it illegal to attach your vessel? The correct answer is a lateral buoy or non-lateral marker. It is illegal to attach your vessel to this type of navigation aid because they are critical for marine navigation and safety. These buoys and markers are meant to guide vessels and provide important information regarding the waterways.
Attaching a vessel to mooring buoys is typically permitted as they are designed for that purpose, allowing vessels to securely tie up. You can also legally tie up to a pier or a fueling dock when the facilities are designed for temporary mooring, assuming that you have permission from the owner or operator. It is essential to follow local regulations and protocols for mooring to ensure safety and abide by the laws.
