The table below was built by taking random samples from back copies of Lloyd’s List which gave vessel’s arrival and departure dates. The table contains turnaround time in days for sailing vessels.

Size	1863-1877	1878-1890	1891-1912
250-499	25,6	21,0	29,1
500-999	29,7	24,2	25,1
1000-1499	38,7	30,5	21,9
1500+	50,5	32,3	21,9
Specific ports
Liverpool	24,1	23,2	26,1
London	25,8	25,8	26,4
New York	21,3	18,6	31,9
Antwerp	30,6	24,3	21,2
Rio de Janeiro	27,7	25,2	20,3
Bombay	29,2	26,1	24,7
Melbourne	35,8	34,3	31,6

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%.

Typical dry cargo power driven break bulk vessels on Europe to Australia run 1870-1970
Year	dwt	Speed	Consumption	Voyage time	Port time	% of voyage	Tons per hatch
1870	2970	7	17,4	232	88	38	46
1890	4530	9	23	257	144	56	54
1910	9496	11	40	235	145	61	64
1930	11719	12	31	229	144	63	69
1950	13066	13	20	217	143	66	90
1970	15473	15	24	213	145	68	107

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

Гораздо интереснее не постоянное время обработки в порту, а почти постоянное время рейса, хотя скорость (вероятно, средняя) удвоилась. Вероятно, возросло время ожидания и простоев всяких.

Надо современную информацию поискать.
