It is a well-known fact that in 80 percent of all fatal boating accidents, the cause of death is drowning. And, in 90 percent of those drownings, the person wasn’t wearing a life jacket. But simply wearing a life jacket isn’t enough. Making sure the life jacket fits properly and the straps are secured correctly is also very important!
Also, it is estimated that a person wearing just a life jacket could survive from 30 to 90 minutes in 32 degree water to indefinitely in 70 to 80 degree water.
