The Peterhead lifeboat was called out twice on Saturday following incidents at the harbour and Craigewan beach.
The first shout saw the lifeboat crew aid two casualties that were in difficulty off the mouth of the river Ugie.
As a result of emergency calls, Aberdeen Marine and Coastguard Agency requested the RNLI Peterhead Lifeboat ‘Misses Robertson of Kintail’ to be launched at 12:44pm.
The incident involved two male teenagers who were in difficulty just off Craigewan beach.
The casualties managed to swim ashore with difficulty, just as the lifeboat crew arrived on scene and were then aided by the Peterhead Coastguard team and ambulance paramedics, and flown by helicopter to Aberdeen Royal Infirmary for treatment.
The second shout of the day took place after 4pm as a personal watercraft was in difficulty off rocks on the north west shore of Peterhead harbour.
Luckily, the uninjured casualty managed to abandon the craft and climb on to the rocky shore prior to the lifeboat’s arrival.
Lifeboat crew members managed to take the craft in tow by the daughter dingy ‘Y boat’ to the Lido for recovery.
