The team were paged just before 3pm today to a report of two sailing dinghies in difficulties at Studland.
A member of the public walking on the beach had spotted the boats and called 999 - Coastguard.
The Swanage RNLI inshore lifeboat was also tasked to assist.
On arrival at Studland, the team discovered that the local Watersports RIB had gone to assist the dinghies with one of them suffering from a broken tiller.
All persons were accounted for , both dinghies were brought ashore and the inshore lifeboat released back to the station.
