T&R Report R-11: Causes and Extent of Lost Time at Sea for Dry Cargo Ships (1969)

The work reported herein was first proposed to Panel H-7 (Seakeeping) of The Society of Naval Architects and Marine Engineers (SNAME) Technical and Research Program by Webb Institute in 1962 as a study to determine the causes and extent of voluntary slowdowns of dry cargo ships. A SNAME purchase order in 1964 initiated the actual study, ship logbooks were obtained and a small sampling was analyzed.
