At some time, it is likely that most boaters may face a situation where you need assistance, if you run aground, have an engine failure, fire, leak or an injury to a member of your crew. Boaters use visual distress signals to attract attention in an emergency, either in the daytime or at night. Of course, using a VHF radio is another very effective way to communicate your situation to potential rescuers, but if your batteries are dead, visual distress signals may be your best hope.
