Keep in mind you have Fins on also. As a former diver I can tread water in fins for a long time. This has nothing to do with having a PFD with you but its another thought as weather you feel safe or not. If Hypothermia sets in if you are in very cold water and theres no one to pull you out or your too far to swim to shore, well then the PFD will keep your body afloat till some one finds it.

This is why in diving you never dive alone. You always have a buddy system. Being alone on the water scares me more than anything else that could go wrong. If Im fishing alone, Im on the shore.

Just my personal opinion.
