There you sit, out of gas or maybe your engine just stopped running ("When was the last time I checked those sparkplugs?") The reason at this point is academic.... your stuck!
Looking around it seems you stayed out later than the rest of the boaters. No help is nearby. The reality of the situation sets in....You may be out there all night!
Question: Is there anyone who knows you are on the water? Does anyone know where you are boating?
So.. if you do not return by a certain time, there will not be an alarm going off? Nautical Safety Books call it "Filing a Float Plan" Simply stated, tell a loved one or neighbor. Someone who will miss you if you are a few hours late. It is a good idea to write the information down. Besides recording when and where you plan to boat, include a description of your boat and registration number. It could make a difference between an uncomfortable and possibly dangerous night and being a little late getting home!
