A large fishing net which is the length of about six football pitches has been lost overboard from fishing boat.
The Buckie-registered Aubretia was left drifting without power
It is so big that the Maritime and Coastguard Agency (MCA) issued a warning to vessels in the Pentland Firth to beware.
It was lost from the Bergen-registered Krossfjord and has been seen by boats.
The Buckie-registered Aubretia was left drifting without power on Saturday after catching its propeller on the net, and was towed into Scrabster.
