By radio and flares
Send up a flare or hail local authorities on your radio.
Doing a mayday call over VHF is still the most common way to make a distress signal, however now all VHF sets have a DSC button which when hit send out an automatic distress signal to all receivers in range with location and distress information.
#1: If at night, by use of a searchlight to send Morse code. A regular flashlight will only work if you are in front of a very DARK background. #2: Day or night: Radio Morse code. #3: Daytime: Signal flags along your forestay or backstay. #4: Daytime: Semaphore flag signalling. #5: Day, or night with searchlight shining on it: Hang your country flag upside-down. This is the internationally-recognized sign of distress.
