The sun has not yet risen over the Boyne Estuary which divides counties Meath and Louth.
A soft blanket of fog covers the river where it meets the Irish Sea.
In the pre-dawn half-light, the navigational beacons stand guard like sentries watching for the day’s first cargo boats.
On top of the main beacon, a tiny dot of red light cuts through the dominant blue to help guide early morning seafarers.
