I don't think the chances of you getting shot are very high. The example you gave was a freak accident. They happen but not that often. If you use a sausage, you decrease that chance by another great margin. Sure, you could still get shot but I wouldn't let it keep me out of the water. If you're really worried about it, buy a yellow hood or something especially recognizable for when your head surfaces. Or, you could always get Bridget Bardot to stand guard. Actually, scrap that last one. The sealers would probably bazooka you for that one.
