I would like to establish
1. the exact distance between Raguva , in Lithuania and Old Libau in
Latvia in 1908 . Raguva latitude 55º34' Longitude: 24º36', now in
Lithuania and Libau -latitude 56,53333 and longitude 21,01667.
2. the exact distance ,in miles between Old Labau and London , Uk in 1911.
3. The approximate sailing time , in 1910 to sail between Libau and London

Dear ashleyd80,

The distance between Raguva and Libau (now called Liepaja) is 164.844
km. The distance between Libau and London is 915.935 km. However,
those are linear distances. For a ship sailing from Libau to London in
1910, the distance is more than twice as long, about 2000 km. That is
beacuse the ship would to follow navigable waters that don't run
straight. Also, she would have had to sail around the Jutland
Peninsula, through the Skagarrak strait, because passenger ships
usually did not use the Kiel Canal (called Kaiser-Wilhelm-Kanal then,
today Nord-Ostsee-Kanal), linking the Baltic Sea with the North Sea.
However, if the ship had taken the Kiel Canal route, her way would
have been about 460 km shorter.
Provided that the ship was running at an average speed of 11 knots
(which is not much, but realistic for a steamer of the early 1900s)
without any stops for re-coaling in ports, Libau-London via the
Skagerrak would have taken about 4 days. The shortcut way through the
Kiel Canal would have taken approximately 3 days.
