Coast Guard Cutters
A cutter is defined as a U. S. Coast Guard vessel of 65 feet or
more in length that has a designated commanding officer and living
accommodations aboard for the crew. During World War II the Coast
Guard operated various size cutters. Many of them can be considered
small ocean going ships. Two types selected here are representative
of all cutters. They are the 165 foot WPC and the 125 foot WSC.
WPC Cutters built before WWII
These were one of the more important Coast Guard subchasers. The
United States built them during the Prohibition era to interdict
smugglers. They also were used on ice patrol. Later the Navy converted
them into subchasers.
