Guernsey’s Marine Ambulance was called out for the third time in three days yesterday evening.
Medical staff and volunteers from the boating community were called to collect a patient in Sark, shortly before 8pm last night.
The Flying Christine arrived back in St Peter Port just after 9pm, where the man was transferred to the Princess Elizabeth Hospital by ambulance.
The two previous call outs had been to Herm.
St John Ambulance staff say they are typically called to the other islands more often during the peak tourist season.
