Thefederal government purchased or built thirty-nine of these vessels, builtin three sub-classes, from 1942-1944. The U.S. Coast Guard(USCG) designed the 180s to service Aids-to-Navigation (AtoN),perform Search and Rescue missions (SAR), carry out LawEnforcement duties (LE), and conduct ice-breaking operations.Members of the class have served in the USCG from 1942 to thepresent. They have significantly contributed to safe navigation on inlandand international waters in times of peace and war.

U.S. COAST GUARD CUTTER SUNDEWHAER No. MN-98(Page 4)SUNDEW was the last of the 180s built by Marine Iron and Shipbuilding and the least expensive witha price tag of 861,589. SUNDEW's keel laying took place on November 29, 1943. The shipyardlaunched her on February 8, 1944, and the U.S. Coast Guard officially commissioned her on August24, 1944.SUNDEW spent the war years stationed in Wisconsin, first at Manitowoc and then at Milwaukee.Though far from the front lines, she played an important role in the war effort by marking safe shippinglanes and clearing them of ice to allow the products of America's industrial heartland to reach the Gulfof Mexico, the Atlantic Ocean, and eventually the fighting fronts.The tender's crew called Milwaukee home until 1953 when new orders transferred the cutter toSturgeon Bay, Wisconsin. SUNDEW operated out of Sturgeon Bay until June 1958 when shereceived a transfer to Charlevoix, Michigan. She remained there until August 1977 when she enteredthe Coast Guard yard at Curtis Bay, Maryland, for a "major renovation" that lasted one year.SUNDEW returned to Charlevoix after the yard period. Her homeport changed to Duluth, Minnesota;birthplace of the 180s, in 1980, and she continues to operate out of that port through the present.SUNDEW's homeport has changed a number of times but her duties have not. She has servedprimarily as an AtoN tender during summer and fall months. During the winter and spring, she breaksice to clear shipping lanes and free trapped vessels. When vessels find themselves in need of assistanceon the Great Lakes and call the Coast Guard, the local SAR coordinator dispatches SUNDEW to helpif she .is in range of the distressed craft.In recent years her duties have expanded to encompass some scientific research responsibilities. Shenow aids scientists in tracking the spread of Zebra Mussels in Lake Superior. She also helps procurewater and bottom samples for scientists studying the Great Lakes. Besides helping the NationalOceanographic and Atmospheric Administration (NOAA) deploy and maintain weather buoys,SUNDEW sometimes serves as a floating weather station and feeds data to the National WeatherService. 1SUNDEW has been a Great Lakes vessel for virtually her entire career. The single exception, besidesthe trip to and from Curtis Bay, was a LE patrol in the Caribbean during the winter of 1987-1988.Outwardly, SUNDEW appears little changed from the day she left the Marine Iron and Shipbuildingyard. There have, however, been significant changes required to keep the tender on active duty for1 Wes Hall, Historical Context and Statement ofSignificance: Cactus, Mesquite, and Basswood Classes,United States Coast Guard 180-foot Buoy Tenders (WLBs) (Castle Hayne, North Carolina: Mid-Atlantic Technologyand Environmental Research, 1997), 23.

At the same time, a bow thruster was installed to give the single screwvessel more maneuverability. The needs and comfort of the crew were also addressed during theoverhaul when shipyard workers installed air conditioning on the tender. Seven years after the majorrenovation program overhaul SUNDEW entered a shipyard for another one. This time, mechanicsinstalled new diesels to generate power for her electric motor. 2As of January 2002 SUNDEW remains on active duty, serving on the Great Lakes. The U.S. CoastGuard has tentatively set her decommissioning date as sometime no later than June 2004. 32Hall, 8.3 Hall,8.
