Final answer:
When selecting visual distress signals for your boat, it's important to have a minimum of three devices that can be used in both daytime and nighttime.
Step-by-step explanation:
When selecting visual distress signals for your boat, it's important to have a minimum of three devices that can be used in both daytime and nighttime. Some acceptable combinations include flares, smoke signals, and an electric distress light. These signals can be used to attract attention and signal for help in emergency situations.
Flares are a common distress signal used at sea. They emit a bright light that is visible from a long distance, making them effective for nighttime signaling. Smoke signals, on the other hand, produce dense orange smoke that can be seen during the day. An electric distress light is a battery-powered light that flashes a distress signal.
By carrying a combination of these three visual distress signals, boaters can ensure they are prepared to signal for help in any situation, whether it is day or night.
