The ship sank near a Bulgarian village that was close to the border with Romania.
Crew members included five Georgians, five Turkish and one Indian, according to Bulgarian Interior Ministry.
The Maritime Agency of Bulgarian Transportation, Information Technologies and Communication Ministry said that all 11 crew members were rescued by the Bulgarian coast guard, before the ship sank at around 2.30pm GMT.
The ship sent out a distress call at around 6am local time (4am GMT), following which a nearby Turkish vessel rescued the onboard crew.
Maritime Agency authorities were quoted by World Bulletin as saying that investigations into the cause of the sinking are continuing, but initial findings show that the main cause was unbalanced weight.
