The boom extends into Cromarty parish.
The World War II anti-submarine boom extended across the Cromarty Firth from a point on the shore about 350m SW from Nigg coast battery (NHG86NW 10.00) to a point on the S shore in the area of Little Rock. The exact location of the end points on the S and N shores are not known.
The boom was constructed of wire, chains and floats. The first boom was constructed across the entrance to the Firth.
