This report presents the results of icebreaking comparison testing between a pair of 140-foot icebreaking tugs (WTGB's) and two larger icebreakers (WAGB's). The tests took place in the Great Lakes in February and March 1981. Testing was conducted in brash ice and in unbroken level ice. Results of this testing indicated that a pair of WTGB's could do substantially the same work as a WAGB at much lower cost. (Author)
