Coastguard tug Anglian Sovereign next to the upturned hull
Divers are expected to inspect the scallop dredger that capsized leading to the loss of three crewmen before the boat is towed to a nearby harbour.
The Aquila overturned off Ardnamurchan Point in the west Highlands on Monday.
Skipper Tony Hayton, Peter Hilton and Thomas Sanderson, all from Cumbria, died. A fourth member of the crew, who is 32, survived.
A fishing boat, the Silver Dawn, has been hired to stand by the upturned hull until it is towed to Mallaig.
The Marine Accident Investigation Branch will investigate why the boat capsized in relatively good conditions.
The survivor was picked up by a yacht, a twister called Arran Comrade, and has been released from hospital.
The other three crewmen were recovered from the water but were all pronounced dead on arrival at Broadford Hospital on the Isle of Skye.
A Maritime and Coastguard Agency spokesman said none of the four was wearing a lifejacket.
He added that wearing the gear may have helped to save their lives.
Fishing industry leaders have paid tributes to the crewmen who died.
A coastguard tug - Anglian Sovereign - was anchored near the upturned hull of the Aquila as a precaution against pollution from the boat.
