Competent harbour authority

Competent harbour authorities (CHA) in the United Kingdom are those harbour authorities that have been given statutory powers relating to the provision of pilotage in their waters. The description was created by the Pilotage Act 1987, at which point a CHA had to be one whose harbour was wholly or partly within a pilotage district where at least one act of pilotage had been performed, or where a pilotage exemption certificate had been in force, between 1984 and 1987. However, the act provided a procedure by which other harbour authorities could be assigned CHA status and some harbours have taken advantage of this process. The Marine Navigation Act 2013 amended the Pilotage Act to provide a reverse process, so that harbour authorities could be relieved of CHA status.
