Adolph Postel, captain of a charter fishing boat, alerted watchstanders about the incident just after 8:30am.
"I heard some hollering. I thought they had just caught a big fish or something," Postel said. "I turned around. The boat had flipped over and they were all in the water."
According to officials, a 21-foot powerboat capsized, leaving three people in the water.
The Coast Guard launched air and boat crews to the scene. By the time their response boat arrived, Postel had taken all three of the distressed people aboard his boat.
One survivor reported having a broken leg. The response-boat crew brought two of the three people aboard and the two boats brought the three survivors back to Station Galveston where local EMS was standing by.
"It was an adventurous morning," Postel said. "We're just glad everyone's okay."
Lt. Spencer Roach, the command duty officer of USCG Sector Houston-Galveston, extended gratitude to Postel for his assistance with the rescue.
"Mr. Postel honored an ancient code among sailors, that you do everything in your power to help someone in trouble and at the mercy of the sea," Roach said. "His quick response led to a happy ending and we are grateful that he was in the right place at the right time."
