With her revised livery, the former HM Customs and Revenue cutter SENTINEL shows the revised branding of her owners, now operating as the UK Border Agency. She is one of their fleet of five cutters, the only one to have been built in the UK, and dates from 1993. Like her sisters, SENTINEL patrols the UK coastline and provides offshore support all year round. She was seen passing Port Glasgow as she made her way upriver to Glasgow for a short visit to the city. SENTINEL and her fleetmates are fairly regular visitors to the Clyde.
