ICEBREAKING AND OPEN WATER TESTS PERFORMED ON THE USCG CUTTER KATMAI BAY (WTGB-101)

The results of icebreaking trials performed on the icebreaking tug, USCGC KATMAI BAY (WTGB-101), are presented. These trials were conducted in Whitefish Bay and the St. Mary's River near Sault Ste. Marie, Michigan, during January - March 1980. Trials were conducted in all modes of icebreaking. Bollard pull tests and limited maneuvering tests in ice were also conducted. Open water trials performed in July 1979 in Whitefish Bay are also reported. These included speed and maneuvering (tactical data) trials. Spiral tests were also performed to determine directional stability. (Author)
