The diver, a 57-year-old man, was found off the coast in the early afternoon.

An Argyll Ferries vessel travelling from Dunoon to Gourock diverted to recover him on board, according to Inverclyde Now, and the Helensburgh lifeboat and a Coastguard helicopter from Prestwick responded to emergency calls. 

A paramedic was lowered to the ferry from the helicopter and attempted to resuscitate the diver, who was brought ashore at Gourock and taken to hospital by ambulance.

Police Scotland has not confirmed whether the man was a sports or commercial diver, and said that enquiries were ongoing.
