The major U.S.-Flag Lakes lines had 63 of their 69 vessels in service on June 1, in total, the same as a year before. However, the dry-bulk fleet was down by two hulls (EDWARD L. RYERSON and JOHN J. BOLAND).
In addition to the previously-mentioned vessels, also inactive so far this season are the cement carrier E. M. FORD and the straight-decker KINSMAN ENTERPRISE.
