USS YP-389 was a United States Navy yard patrol (YP) boat that served in World War II.

The ship was built in 1941 as the fishing trawler Cohasset at the Fore River Shipyard in Quincy, Massachusetts, for R. O'Brien and Company.

[2][4] Six American sailors were killed in action and eighteen others went into the water without lifeboats because lowering them meant being exposed to accurate enemy fire and the liferafts had all been shot away.

U-701 continued to scour the American East Coast for a few more weeks until being sunk by United States Army bombers not far from Diamond Shoals (7 July 1942).

[2] In August 2009, a National Oceanic and Atmospheric Administration-led team aboard the NOAA research ship NOAAS Nancy Foster (R 352) found and photographed a wreck 20 nautical miles (37 km; 23 mi) off Cape Hatteras, North Carolina, and on 9 September 2009 the team's leader announced that the wreck had been identified as that of YP-389.
