Sailors.pngSailors represent the trained seamen of a nation. They are used for ships just as manpower is used for troops. A country whose stockpile of sailors is depleted will be unable to build new ships or repair damaged ones.

Sailors differ from manpower both in what they are used for and in how they are acquired. Only coastal provinces provide sailors, and the amount of sailors depends on the total production development in a province. Sailors are required when constructing new ships, and when ships are “repaired”. Not all ships require the same amount of sailors, with heavy ships needing the most and transports the least. AI nations are coded to never run out of sailors since version 1.24 because they were too ineffective at managing them, so sailors are in effect only relevant to player nations.



The maximum sailors available to a country is the sum of the province sailors.


Province sailorsEdit

Province sailors is the amount of sailors each province contributes to the national sailor maximum. It is computed as follows:

Where base is 30 sailors per point of   development in the province.

Using sailorsEdit

Sailors are used to man naval vessels and when raising marines. Different vessels require differing numbers of sailors to be at full strength. Similarly, sailors are required to return a damaged ship to full strength, and the number of sailors used to do this is an equivalent fraction of that for the whole ship (repairing a ship from 50% uses 50% of its initial sailor cost). It takes  1000 sailors to recruit a Marine. Sailors are also used for reinforcing depleted regiments.

  Ship type
200   Heavy Ship
100   Galley
  •   Light Ship
  •   Transport

Sailor maintenanceEdit

When fleets are on missions (i.e. not in port), they cost a certain number of sailors each month to maintain.

Ship type   Monthly sailor maintenance
  Heavy ship 4
  Galley 2
  Light ship 1
  Transport 1

A number of ideas and bonuses can reduce the number of sailors needed for missions.

Sailors recoveryEdit

Sailors replenish over time until they reach the maximum level. It takes 10 years[2] to fill the sailor reserves from zero. The monthly recovery rate is:


If a nation owns at least one coastal province, sailors have a minimum recovery rate of 5   sailors per month.

Sailor recovery speedEdit

Sailor recovery speed modifies the recovery rate of province sailors.

+100% as invasion nation[1]
+10% with   parliament and “Impressment of Sailors” or “Expand Navy” as active issue
+0.2% for each point of   navy tradition[1]
−1% for each point of   war exhaustion[1]
−20% for having Recruitment Sabotaged [1]
−100% if bankrupt[1]

Mothball fleetEdit

Mothballing a fleet will make it immobile and decrease its maintenance costs by 50%, and will cause it to lose 5% of the sailors in the fleet per month (also durability) until the fleet reaches a minimum of 25% sailors/durability. Sailors lost from mothballing are returned to the national sailor pool, but only up to the national sailor limit; any additional sailors above the limit are lost. Un-mothballing a fleet will cause it to repair at the standard rate.

Raid CoastsEdit

Main article: Raid Coasts

Certain nations can gain sailors from raiding another nation’s coastal provinces, even if the maximum number of sailors has been reached. A province that has been raided cannot be raided for another 10 years.

The efficiency of raiding is reduced by fleets on pirate hunting patrol.

Exploit developmentEdit

Main article: Exploit development

By exploiting the   base production of a province, a nation can get a large number of sailors instantly. Doing this will give 60 months worth of that province's sailors.
