How can a Life Jacket with 22 lbs of buoyancy hold up a 200 lbs person in the water?
You have to do the math! Approximately 80% of the body is water.

Water in the body has no weight in water. So now we are down to having to support only 40 pounds.
200 lbs. X 80% = 160 lbs.
200 lbs. - 160 lbs. = 40 lbs.

But the PFD only has a buoyancy rating of 22 lbs. How can it hold up 40 lbs?

On average our bodies also have 15% fat and fat is lighter than water.
200 lbs. X 15% = 30 lbs.
40 lbs. - 30 lbs. = 10 lbs.

Now you can see that the average 200 lbs person only weighs about 10 lbs in water. The 22 lbs of buoyancy in your PFD is more than enough to keep the person afloat.
