The range of a marine signal flare depends on the type of flare. Typically, handheld flares have a range of approximately 1-2 nautical miles, while aerial flares can reach up to 6 nautical miles.

Smoke signals are used to signal distress, attract attention, or mark a position in marine emergencies. They produce thick, colored smoke that can be easily spotted from a distance and can be used to guide rescuers.

Legal requirements for marine signal equipment vary depending on the size, type, and location of the vessel. In general, most recreational vessels are required to carry a minimum amount of safety equipment, including visual distress signals, sound-producing devices, and a means of signaling for help.

There are various types of marine distress signals, including flares, smoke signals, sound-producing devices (whistles, horns), and electronic devices (EPIRBs, PLBs). Each type of signal serves a specific purpose and has its own advantages and limitations.
