So, I'm thinking of getting a boat to use out in the gulf of mexico and possibly do some diving off of. I know other people do this but I would like to know when you are diving off your personal boat if you always have extra people stay up on the boat? Diving right now would just be me and one other person and we dive as buddies so if we went alone the boat would be on the surface alone. I doubt anyone would try to steal it but that would be a major concern. I'm just curious as to what other people who dive from their own boats do?
