The table suggests that all sailing vessels showed an improvement in the turnaround time between 1878 and 1890. This improvement was sustained in the final period for only the largest vessels or those ports which still catered largely for sailing vessels. In port catering for the new steam vessels the sailing ships were relegated to the older areas and given lower priority as regards cargo-handling. This probably also indicates that the larger sailing vessels were in more secure trade routes, i.e. they could still find cargoes. The smaller vessels were less capable of finding ports with ready cargoes – hence their longer time in port.
It is often said that at that time a ship spent half its life in port, though the next table indicates that on Australia trade around the early 1920s, the percentage of time spent in port was nearer 40%.

What is interesting in the preceding table is the virtually constant total port time of 140 days from 1890-1970.
