The two people in the boat were picked up by a leisure boat, and could be taken to hospital.
Their injury situation is unclear.
- It was an open small motorboat, and according to information, it was broken off in the middle when it went over a surge, says management operator Peter Tistam at the Greater Stockholm Fire Brigade.
The rescue service was on site with a lot of resources to assist the ambulance staff, but the distressed had already been brought ashore.
They are both said to have been conscious and able to talk when they were taken to hospital.
