How to increase the buoyancy of a container.

Would an empty barrel stuffed with lifejackets and sealed be able to support more weight floating on the water than just the empty barrel? Ie. does a buoyant object increase overall buoyancy only if is directly in contact with the body of water?

I am trying to figure out how I can get something about the size of a keg to support my weight (~200lbs) on the water. I want to try using something like a keg for logrolling like in those lumberjack challenges. But from what I understand if the keg only holds 100lbs of liquid it will only be able to displace a 100lb person when it is empty. Would sealing additional buoyant material like life jackets inside make the barrel more buoyant?
