Final answer:
For boats 6 meters or less in length, it is mandatory to have a buoyant heaving line at least 15 meters in length, distress signals, flotation devices, and a sound-signaling device as safety equipment.
Step-by-step explanation:
Safety Equipment for Human-Powered Vessels
Understanding the safety requirements for human-powered vessels is essential for ensuring safety on the water. For boats 6 meters or less in length, there are specific regulations to follow. Among these, a buoyant heaving line at least 15 meters in length is mandatory. This equipment is crucial for rescuing individuals who may have fallen overboard and for providing assistance in man-overboard situations. In addition to the heaving line, distress signals are also required onboard to allow for effective communication in emergency situations. These may include flares, flags, or sound-producing devices. Furthermore, all vessels must have an adequate number of flotation devices, such as life jackets, to ensure personal buoyancy if someone ends up in the water. Finally, a sound-signaling device, such as a whistle or horn, is necessary to signal one's position in times of reduced visibility or to signal distress.
