Poole D class was requested to launch at 09:45am (Saturday May 7) to a report of an 18ft white hull dinghy capsized by the harbour entrance.
The lifeboat made good speed to the entrance of the harbour to investigate.
Conditions were good, there was a slight sea, force 3 northerly wind.
The lifeboat volunteers passed an ocean going white rowing boat, which may have been the vessel reported as from a distance it fitted the description.
The lifeboat continued to do a recce of the area up towards Canford Cliffs.
The lifeboat volunteers spoke with the RNLI lifeguards who were on the beach to see if they had seen anything untoward and then continued to check the area up to Shell Bay, then inside the harbour up to Blood Alley. As nothing untoward was found and nobody else in the vicinity had seen anything, it was deemed that it was a call with good intent so the lifeboat was stood down and returned to station.
The D class was ready for service by 11:30am.
Poole Lifeboat was then tasked again at 7.20pm to reports of one person onboard a jetski towing another in between Old Harry Rocks and the Harbour entrance. However, the towing jetski had run out of fuel.
In flat calm conditions, with nothing visual, further information came through that the two jetskis and one person were near the shore so a search of Studland Bay commenced.
The were soon located near the Training Bank in Studland and found one of the jetskis to be partly submerged and aground.
Poole Lifeboat volunteers offered to tow the floating jetski and one occupant back to Baiter Park - however this offer was declined. At this stage Poole Lifeboat requested Swanage Coastguard to attend.
As discussions continued to take place and with the tide dropping the second jetski was aground and the person now ashore. The offer to take the person back to Baiter Park was again declined.
With no other options available from the lifeboat, the volunteers left the scene leaving the person on the beach in the care of Swanage Coastguard.
Lifeboat refuelled and ready for service by 9:30pm.
This was the 40th launch this year.
