Trade Ship

Overview
The Trade Ship is a tile improvement that provides a unique way to generates coins and culture. The Trade Ship consumes trade-able items that are stored in the cargo hold, and in return provides profits of coins and culture every hour as well as a chance to generate items. If the Trade Ship runs out of Cargo to ship, it will not decrease its current level and it will not generate coins, so it's important to keep the cargo hold stocked at all times.

Biome Bonus
The Trade Ship has been designed around increasing the productiveness of coastal cities. The Trade Ship produces hammers along with the Lighthouse, Ship Yard, and Fishing Boat depending upon the biomes within the civilization.

How does it work?
The Trade Ship produces coins by shipping items from its cargo hold (Outgoing chests) every hour. If any trade-able items are in the cargo hold, the Trade Ship will gain 1 point towards its next level. Unlike a Cottage, the Trade Ship does not lose points if the cargo hold is empty. Once the Trade Ship has the required Cargo Delivered(cargo/hours) it will level up. Upon leveling up, the Trade Ship will increase its culture output and add additional chests depending on its level.

In addition to leveling up upon delivering the require amount of cargo, the Trade Ship culture output and incoming chests can be increased with Town Upgrades.

Placement Considerations
Like all Tile Improvements, Trade Ships can be built anywhere inside your town's culture borders. Trade Ships must be built in water based biomes. If they are not built on a protected town plots, they can be utilized by anyone as a place to live, and can be griefed. They will still function unless destroyed during war.
