Mariella didn't receive any survivors from helicopters, one injured survivor was picked up from Mariella by the Finnish helicopter X 92 for emergency transport to hospital by stretcher. One injured survivor was picked up from Isabella by Finnish helicopter X42 by stretcher.
These were both wire transfers as the ships were rolling too much for a landing.
Only two helicopters managed to land on ships to transfer survivors to them, they were both Finnish helicopters, OH-HVG got on to Symphony and OH-HVD got on to Europa.
After this it was too rough to land safely so all survivors were taken direct to shore, that is one of the reasons more helicopters were called in to the rescue.
Here are all the wire transfers.
Y 74 another Finnish helicopter lowered medical staff on to the Symphony by wire as it was too rough to land on the deck.
X 42 attempted to land seven men of the Turku city fire department aboard Europa to serve as rescue men but this was abandoned because the vessel was rolling so badly that it would have been dangerous to land on the helicopter deck. They therefore stayed with the helicopter all day as first-aid personnel.
X 62 In the late morning, attempted to land five physicians and six firemen and an air traffic control office aboard Europa however, it proved impossible to land, as the stern deck of the vessel was rising and falling about 10 metres at a time so they were winched down instead.
Y 65 rescue man got stuck on the winch rope when it jammed and had to be flown to the Europa where he was put on to the deck.
Y 75 lowered medical staff to the Symphony in the afternoon.
