If you're swimming abilities aren't quite on par with Michael Phelps, perhaps you may want to take us up on a snorkel vest!  Like a lifejacket, a snorkel vest is designed to keep you floating on top of the water.  Unlike a life jacket, a snorkel vest is allows you to place your face in the water so you can enjoy snorkeling without the fear of, um, well, you know...drowning!
