Upgrades are not linked to a specific ship; once an upgrade is bought, it can be used on every ship. The costs and stats of each upgrade are listed in the tables below.
Suggested order of upgrades:
- First, The Deck Items (because there are two on each ship)
- Second, The Ship's Hull (the Hull of Glory is the 2nd ship item to buy in The Bowl, after the Skeletal rudder. This is because the Golden Hull available in The Skull, is the best Morale-strong hull upgrade available through The Hook and The Scythe, until you reach The Bowl and the Hull of Glory. In The Hook and in The Scythe, only Combat-strong and Seafaring-strong hull upgrades are available, therefore the Golden Hull is the best Morale-strong hull available through the Skull, The Hook and The Scythe.)
- Third, The Ram/Figurehead (because they have comparatively small bonus).
- Last, The Rudders (the influence of lower level rudders is hardly noticeable and speed cap is low enough that a captain and crew member with Solidarity is a better investment).
- When reaching The Bowl, the rudder becomes more important due to long trip times, so buying the Skeletal rudder first may be beneficial.
- When reaching The Shield, buying the Tengu rudder first can be beneficial, as voyages to the Shield can take 13 hours and 40 minutes at average ship speed, but at maximum ship speed, voyages to the Shield will be completed in 10 hours and 40 minutes - allowing the player to deploy two fleets of ships in under 24 hours. Thus with the Tengu rudder, 8 standard voyages to the Shield can be completed in under 24 hours.
- However, the aforementioned two points depend on the free time available to the player. If you are unable to send a new voyage soon after the ship arrives, having bought a faster rudder is a waste of resources that could have been applied to more helpful ship upgrades.
