Version 2.1 includes all of the ships already contained in 2.0, plus three additional ships.
Or, are you saying you don't want the additional ships included in 2.1? :hmm: If you want to get rid of the three additional ships in 2.1, just delete the folders for these ships. The folder names are NLUS, NPPL, and NLPL. (Be sure to disable the mod first)!!
If you are uncomfortable deleting stuff, I have already provided separate links for both 2.0 and 2.1.
EDIT: Now I see what you mean by version 1.2. Version 1.2 is for my TrampSteamerFix. Both STzSinkingShipFix 2.0 and 2.1 replace and add to the TrampSteamerFix. Don't use the TrampSteamerFix mod anymore since it only contains fixes for the tramp steamer and is out of date, to boot. I will edit the readme file to try and make that a little more clear.
