Navigable Rivers

This mod introduces a river traversal system, expanding upon the use of rivers


River units are restricted to only move on the sides of rivers, lakes, and sea tiles adjacent to land. Movement upstream will be only allowed on one side of the river, movement downstream will be on the opposite side. River units may move across all terrain without taking attrition and ignore terrain cost

Naval units can't enter rivers, this is for realism (big sea ships can't enter narrow rivers) and balance reasons

If you would like to move naval units through land, I recommend my other mod - Canals

Unlocked at metal casting
Can both melee and range attack
1 Range, 4 moves
Ignores enemy ZOC as it is on the river

Upgrade of the Longboat at steam power
Has 2 range, 5 moves and indirect fire, but requires coal

Both these units use ranged promotions, but have volley instead of +1 range

Unlocked at sailing
Civilian unit, 4 moves
May carry 1 land unit as cargo
Also has the ability to "ferry" units across the water tile, this allows all land units to cross the tile as if it is land. The Barge can't move again until it stops ferrying
Ignores territory, allowing you to move units through non-open borders

All these river units require the River Port in the city to be built...

Unlocked at pottery
1 Maintenance
Forms a city connection with other cities with a river harbour that are on the same river, under a few conditions:
The tiles along the river connecting the cities must be discovered, not blocked by an enemy city and if there is a lake in-between, the player must be able to embark

• The AI won't build barges as they don't know how to use them, but they will build and use Longboats/Gunboats
  
• River units will automatically position themselves on top of the river, even if you have quick movement enabled
  
• Fishing tech has just been added for realism, it doesn't change anything
  
• Loading a land unit onto a barge while it is on water is prohibited
  
• You may see a warning that the fishing boat will be removed when attempting to ferry units, ignore this because it won't be
  
• Barges can't ferry units while having cargo
  
• Land units in barges won't take attrition damage and can be stacked with another military unit

Requires a DLL, and therefore can't be used on multiplayer or with other DLL mods. Can be used with Howard's original VMP instead. This mod should also be compatible with Vox/CP but not recommended as I can't guarantee there won't be issues. Will conflict with "Galleys for Civs"
