Steven Poust and his son Chase, 7, and daughter Abigail, 4, went fishing and swimming in St. Johns in Jacksonville, Florida. An unfortunate thing happened as Abigail was holding on to the back of the boat. She lost her grip and was swept away by strong currents. Chase who was also holding on to the back of the boat, went off to pursue his sister.

According to the Jacksonville Fire and Rescue Department, the law requires children under age 6 to wear life jackets, but older children and adults are exempt. Luckily, Abigail was wearing a life jacket that day.

Steven Poust jumped out of the boat and followed after his children instead of using the boat to pick them up. He quickly realized he wouldn’t be able to save them and told them that he loved them because he was not sure what would happen.

He urged his son to swim for help while he stayed with Abigail.

Chase, only 7 years old, amazingly swam for an hour against the current. He switched between dog-paddling till he was tired then floating his back to catch his breath.

Chase’s father said their survival was due to his son’s ability to swim to shore and alert authorities.

He thanked God that they were all still here.

Chase’s swimming abilities shocked a lot of people. Chase simply and honestly said he didn’t know when asked where he had learned to swim so well and deal with emergencies.

Fortunately, no one was killed, and the family hoped that this ordeal would teach them to avoid a similar situation in the future and be a lesson for others to maintain a state of situational awareness.
