Squall,
Morgan Robertson's novella was published in 1898 as Futility and was re-released in 1912 as The Wreck of the Titan. Simularities included, but are not limited to ...
Description Length The Titan 800 ft. The Titanic 882.5 ft.
No. of Propellors The Titan 3 The Titanic 3 Watertight Compts. The Titan 19 The Titanic 16 Passenger Capacity The Titan 3000 The Titanic 3000 Gross Tonnage The Titan 45000 The Titanic 46328 Nickname in both cases was 'Unsinkable', Horsepower The Titan 40000 The Titanic 46000, lifeboats listed for The Titan was 24 and The Titanic had 20,
Speed at Collision in The Titan was 25 knots while the actual speed of The Titanic was 22.5 knots, the month the voyage started in both cases was April, the side striking the iceberg was Starbord both in the book and actuality, the time was listed as near midnight in the book and the real time was 11:40 P M, and the location of the collision in both cases was the North Atlantic, a few hundred miles off the U.S. coast, and the number of deaths listed in the book was 2987 while the Titanic actually lost 1523.
and as I said, there are other striking simularities. There were some changes made when the book was reprinted in the 1912 version, some of which, I believe, you incorporated in your post, however the book did list the number of passengers as 3000 with only 23 being saved.
If you cannot find the book mentioned, please be advised that it is reprinted in its entirity in a volume called The Complete Titanic by Stephen J. Spignesi.
I hope this is of some assistance.
Will
