One of the women suffered a minor head injury, said Homer Fire Department Captain Steve Boyle.
The skiff did not sink or take on water, he said.
"They didn't even get wet. They managed to drive the skiff to a beach near Port Graham, and they got help," Boyle said. The department responded to the call shortly before 6 p.m. Sunday, meeting a flight from Port Graham.
"The Port Graham EMTs transported the patients to Homer, and we met them and transported them to the hospital," Boyle said. "One of them had a moderate strike to the head. The injured woman was treated. The other two were brought in for observation."
Alaska State Trooper Jeremy Rupe said alcohol was not involved in the accident.
"From what I understand, the sun was going down, and they might have gotten blinded a bit," he said. "There was apparently some damage to the boat, but they were able to get back to the beach on their own."
