USCGC Sea Devil is the 68th Marine Protector-class coastal patrol boat to be built, and the first of four to be paid for by the US Navy.

[1] Her home port is Kings Bay, Georgia, where she and her sister ship Sea Fox are assigned to one of two Maritime Force Protection Units.

They are all equipped with a (water)jet-propelled pursuit boat, that is deployed and retrieved via a stern launching ramp, enabling it to be used without bringing the cutter to a halt.

[1][5] The main armament of the standard Marine Protector cutter are a pair of .50-caliber (12.7mm) Browning machine guns, mounted on the rail to either side of the vessel's foredeck.

The long range accuracy of these weapons is low, when fired by a gunner on a pitching deck, aiming using "iron sights".
