Are you REALLY prepared to take that Boat-- AFLOAT?

So, you think you have everything you need for a day, on your boat, on a lake or the bay, the ocean or the delta? What items do you need to make your day safer and more fun? Have you thought about that potential emergency? What happens if your boat incurs a devastating leak from hitting an object that is submerged?
What about the other occupants in your boat? Are you prepared for an emergency should you not be able to return to the pier in short order? What about the safety of those guests you've invited to come along for just an outing, for fishing, or maybe for that bit of water skiing? Do you have any safety equipment on board? If there are skiers, do you have that red warning flag to let other boaters and skiers know you have guests in a water toy, or in the water just swimming around or diving, or at the ready on skis? Maybe it's not required where you take your boat afloat, but do you know? Do you have children on board? Do you have safety vests for everyone including the small children aboard? How about plenty of drinking water, sodas, or snacks?
What about the sun? Do your guests have protective eye wear, goggles, or sun glasses? Do you? What about caps or some protection for scalps? How about sunscreen? The worst sunburns can be gotten from the sun's rays dancing off the water providing bounding UV rays, yielding very red and chafed skin, as well as damage to the eyes from the constant bright glare! Are you prepared?
What happens if the motor goes and you become stranded? Do you have any type of communication device, like a CB or 2-way radio. Cell phones may not work. What about a set of paddles, or oars of some type?
Lastly, have you thought about something as basic as a First Aid Kit? What about flares? Does anyone have extra dry clothes, maybe a blanket or two on board, or a tarp? You don't have to bring the "whole house," but a word to the wise about carrying at least some of these items, even on a short day trip, on your boat afloat. Are you REALLY prepared to take YOUR boat--afloat?
