[[File:Port.png|thumb|A '''Port''' when it's built.|x200px]]
This [[Buildings|building]] spawns [[Trade Ship|trade ships]] and allows you to build [[Warship]]s.

The first [[Buildings|building]] costs 125,000, then the cost doubles for each one you buy until the price reaches 1,000,000.

[[Trade Ship|Trade ships]] sent out make more [[gold]] the farther they have traveled from their [[Port|ports]].

= Trade Ship Spawning =
[[Port|Ports]] check every 10 ticks if they should spawn a [[Trade Ship|trade ship]]

Spawn chance is calculated based on number of owned [[Port|ports]], number of owned trade ships, and number of all trade ships

<math>\text{spawnChance} = \frac{1}{\left\lfloor \frac{25}{\sqrt{\text{baseChance} * \text{portMultiplier}}} \right\rfloor}</math>

Where $\text{baseChance}$ is equal to 1 when you own less than 3 trade ships (exclusive), otherwise it is:

<math>\text{baseChance} = 1 - \frac{1}{1 + e^{\left(-\frac{\ln(2)}{10} * (\text{numOfShips} - 55)\right)}}</math>
[[File:Desmos port baseChance v26.png|alt=A graph|thumb|The relationship between the total number of ships and baseChance]]
In short, this means that the more ships there are on the map, the less likely more ships are to spawn, with a small number having only a very small effect. At 25 ships, the chance is 88%, at 55 it's 50%, at 100, it's just 4%.

<math>\text{portMultiplier} = \frac{1}{1 + \frac{\text{portsOwned}}{10}}</math>

More [[Port|ports]] = lower spawn rate **per port**. Gradual decay prevents scenario where more ports => fewer ships **overall**.

There is no spawn cap.

= Trade Route Selection =
[[Port|Ports]] will only trade with other players (not their own [[Port|ports]]). Trade partners are prioritized in this order:
* Closer [[Port|ports]] get double chance of being selected (proximity bonus)
* Allied [[Port|ports]] get double chance of being selected

[[Trade Ship|Trade ships]] are free to build and don't count against unit limits.

= [[Gold]] Generation =
{{Update|inaccurate=yes|Reason for being outdated=If ports are very close, the gold gain is significantly reduced}}
[[Gold]] earned is based on ''Manhattan distance'' (which means the sum of the absolute differences in x and y coordinates) between [[Port|ports]] and the number of ports you own:

<math>\text{gold} = (100000 + 100 * \text{distance}) * \text{bonus}</math>

Bonus is a value which is dependent on the number of ports you own. The more ports you own, the smaller the increase, the medium point is at 4 ports with a bonus of approx. 1.9. The bonus is an example of [https://en.wikipedia.org/wiki/Hyperbolic_growth hyperbolic decay].

<math>\text{bonus} = 1 + 2 * \frac{\text{portsOwned} - 1}{\text{portsOwned} + 4}</math>

Both the source and destination [[port]] owners receive the full amount.

Longer trade routes are more profitable (linear scaling with distance).
