HMC Vigilant is a Border Agency (customs) cutter of the United Kingdom.

She was launched by Damen Shipyards in the Netherlands in 2003 and is one of four 42-metre (138 ft) cutters operated by the UK Border Force.

She was built in 2003 in the Damen Shipyards in the Netherlands, and has a steel hull with an aluminium superstructure.

[3] Much effort has been expended in making her quiet to reduce crew fatigue; the engines are raft-mounted, decks throughout the ship are of a floating type, and the compartments are constructed on a box-within-a-box principle.

[3] A single Promac bow thruster is installed[3] for slow speed manoeuvring in confined spaces.
