HMC Sentinel

HMC Sentinel was a patrol ship operated by the Border Force in the role of patrolling the waters of the United Kingdom. It is a Vosper Thorneycroft 'Island Class' vessel and was commissioned in 1993.

History
HMC Sentinel entered service in 1993 with what was then HM Customs and Excise (HMCE). HMCE merged with the Inland Revenue in 2005, and the cutter fleet became part of the newly founded HM Revenue and Customs. In 2008, the fleet transferred to the UK Border Agency and then to UK Visas and Immigration, both established to maintain the UK border, and it operated as the oldest vessel in the UK Border Force's fleet of five cutters. HMC Sentinel was decommissioned July 2013 in Portsmouth, Hampshire.

Prefix
From the merger of the Inland Revenue and HM Customs and Excise into HM Revenue and Customs on 18 April 2005, customs cutters changed their prefix from "HMRC" (Her Majesty's Revenue Cutter) to "HMCC" (Her Majesty's Customs Cutter). Following the transfer to the UK Border Agency this was shortened to the present "HMC" (Her Majesty's Cutter) and a new livery was applied to the fleet.

Propulsion
The cutter is fitted with twin Caterpillar diesel engines (Caterpillar 3516B DI-TA elec Diesel Engines 4,176 kW; 5,600 hp) and a Perkins CV8M600 Diesel Engine.
