I had a friend call me to come "rescue" him. his fresh water pump broke and left him stranded. he got towed by another boater to the closest marina. but his truck was 10mi away. long story short he had a vhf radio and tried raising someone to help him. he says he tried the emergency channels and several others but never got a response. we are in the upstate of SC. lakes,hartwell,keowee, and jocassee. he was on keowee close to jocasee. I guess my question is what is protocall and when it isnt a life and death situation what to do, and is there anyone monitoring or is it a waste of time to have a vhf radio on a lake. by the way he did try the radio on a previous trip and was able to talk to other boaters so the radio works.
