wow that's it! those football players probably swam back to shore if the water is 70 degreesFloridaRob;2663545 said:water temp in the Gulf is about 68 degrees.

Lets hope they have their life vest on and they are floating nearby.

goshan;2663552 said:Regardless, if they have life vests on, Navy type or not, they will not sink.
So there is hope because they haven't found bodies yet.
Also, I thought almost all life preserves would keep you afloat without having to tread water--but I am certainly no boater.
jobberone;2663581 said:It will keep you afloat but in really rough seas you can get pounded. Never been in the water with just a life vest on in open water but I've been lost for awhile at sea with my BC on. It's amazing how fast I was taken away from eyesight of the boat. Obviously they found me but I can see where really rough seas could be a problem. And that was only 3-4ft seas.
The currents will likely take those three and keep them relatively close. There is still hope for them.
ABQCOWBOY;2663580 said:68 is an average mean, I would assume. That means that the temp will fall lower in the evenings and rise in the day. Most people believe that a person who spends significant time in the water dies from drowning but really, it's hypothermia. There are three different stages of hypothermia but essentially, the average person, depending on water temp, has a certain amount of time before there body just shuts down. In waters with a temperature of 68 to 70, your probably talking about maybe two day, maybe less, if you have a good vest. If you don't, that means your treading water and your body shuts down much quicker. The more you swim or struggle, the more heat your body turns out and the quicker the effects of Hypothermia set in. Eventually, you just lose the ability to opperate your body.
ABQCOWBOY;2663603 said:The problem is that while a vest may keep you afloat, if it does not support your neck and your head, you will have to expend energy to keep your head out of the water. More heat escapes out of your head then anywhere else on your body. If your head is in the water, the effects are more dramatic. Even if your just treading water, the body will cool more quickly if your head is in the water as opposed to out. That only heightens the effects of Hypothermia.

FuzzyLumpkins;2663633 said:lol who told you that? density is density.

life vests aren't meant to support you for days
FuzzyLumpkins;2663639 said:that was before plastic and thus foams when life vests were dependent on pockets of air of liquids that were less dense. Foam does not have that issue.
