The team were tasked on Saturday to a report or a possible dinghy in trouble in Swanage Bay.
The call reported a dinghy or fishing boat with 8 people going round in circles at the northern end of the bay.
On arrival and working the watch keepers at NCI Peveril Point , the bay was checked.
The only people who had been out on the water were the local rowing club and they were now safely ashore.
A visual search was carried out but nothing further was found.
