I don't know about all parts of this state, but there really is no formal rescue units on the water, other than the Coast Guard and in these parts, by the time the Coast Guard could make it here from the nearest base, they'd probably be too late. Our Sheriff Dept. does have a boat, but it is normally only in the water to investigate a drowning, or maybe a crime related to the water. They have no ability to respond in an effective and timely manor.
I would not favor the state, county, or local government involving itself with water rescue. It wouldn't be practical; the expense could not be justified and there simply is no money for it. I should say that if such a program were to be initiated, I can guarantee you that the money would have to come from some kind of boating license. There already is a sticker required for power and sailboats, but the purpose of that is strictly for state revenue. This state is over $5 billion dollars in the hole and getting worse by the day and I for one am not interested in contributing one more penny toward that failing enterprise.
Government cannot and should not be the nanny.
I had a personal experience a number of years ago when I flipped a small sailboat. A city cop saw it happen and came ripping down the highway--siren blaring and lights flashing. My interest was to right the boat and get on with it. The cop was insisting that he drag the boat on shore over the rocks. I told him very firmly that he would not be dragging my boat over any rocks and that he could be on his way, thank you. I also had a couple of encounters with the Coast Guard while sailing in my big boat. One young guardsman told me to not sit on the gunnel as the boat was heeled over. I just politely sailed away.
The point is that I'll take my chances. I don't need, nor want govenment to wipe my nose.
