The United States Coast Guard's Sentinel class cutters, based on the Damen Stan 4708 patrol vessel design, are 47 metres (154 ft) long and 8 metres (26 ft) wide.

According to Sanjay Badri-Maharaj, of the -Institute for Defence Studies and Analyses, described how adding an autocannon and military class sensor suite to the USCG's Sentinel class increased its cost per vessel from $20 million USD to $65 million.

Many of the agencies that employ these vessels have them delivered without armament, or solely with small arms.

The vessels are equipped with a horizontal thruster in their bows, to aid maneuvering in tight conditions, such as mooring in crowded anchorages.

A 5009 vessel MY Ocean Warrior was also built for Sea Shepherd Conservation Society in 2015–2016.
