The Nancy Glen fishing vessel has been raised from the seabed in an attempt to recover the bodies of two missing fishermen.
Duncan MacDougall and Przemek Krawczyk were on board the boat when it capsized in Loch Fyne in Argyll and Bute on January 18.
The alarm was raised by a third fisherman who was pulled from the water by the crew of a passing boat.
A major search was launched by police and coastguard teams.
On Wednesday, a specialist lifting barge was brought to the loch where the boat sank in January.
A Crown Office spokesman said: “Work has been ongoing overnight and today to raise and secure the Nancy Glen.
“Salvage teams who have been on board the vessel have described finding human remains.
“While the vessel has now been lifted clear of the water, it remains unsafe for specialist officers from Police Scotland and the Scottish Fatalities Investigation Unit to enter the boat and complete the recovery and identification process.
“This process will not be completed until it is deemed safe to do so and the specialist teams will remain on standby.
“The families are being kept up to date with the progress being made.
“It is anticipated that the teams will be able to continue their work tomorrow.”
The Marine Accident Investigation Branch (MAIB) has already conducted a seabed survey of the ship.
The MAIB said it could not raise the boat but the Scottish Government stepped in to work with salvage specialists and the families of the crewmen to support efforts to retrieve the bodies.
A police underwater unit boat was at the scene on Loch Fyne on Wednesday and investigations are continuing.
