This mod was made with the intention of making the game more realistic. 
Ships out of wood will have a strongly decreased health.
I have divided the cannons of the ships into small and big guns.
The Battlecruiser uses the big guns while every single other ship uses the small ones.
The damage per shot depends on type of cannon and number of them in the ship.
The old cannons need 14s to reload, big modern guns(Battlecruiser) need 10s and modern guns with Autloader(Monitor) need 5s.
The Monster Gun can now kill nearly every ship with a single shot but is therefore extremly fragile.
The speed of Sailing Ships depends now on scale and number of sails. Clipper and Ship of the Line are the fastest ones.
I wish you fun with ANNO1800 and my mod!

Update 2.0 ------------------------------------
Added a .xml table for the pirate ships.
Added an alternative version with a stronger Monitor. (less accurate but better for game fun)
Added a .xml table to overwrite the flagship with a copy of the ship of the line.
Added a .xml table to double the range of modern weapons.
Added a .xml table with a rebalance of the battleship from nncknm's battleship mod. (You still need the original mod from https://www.nexusmods.com/anno1800/mods/39. This table only changes the stats of the battleship to better fit the new balancing.)

Update 2.1 ------------------------------------ 
Added a .xml table with a buildable flagship called "corvette". (reused old preorder flagship GUID (only english and german localisation))
Added a .xml table that should prevent the AI from building steamships.

Update 2.2 ------------------------------------ 
Added a .xml table that rebalances the coastal artillery.
Added a .xml table that makes you able to produce cannons in the new world. (Used GUIDs = 420006 - 420016 ; they were unused by the game developers)

Update 2.3 ------------------------------------ 
Fixed the flagship speed bug.
Removed the flamethrower and other ammotype rebalances. (Because outdated)
Tested if the GUIDs (420006 - 420016) are still not used by the developers.
Flamethrowers, AAs, special ammo types and airships ARE NOT BEING TOUCHED by the mod. (Because I have no clue how airships work but I may revisit this part some time later)
