A December 2025 player report says to open the Fleet tab, select the boat, and use the cost box at the end of its Fuel bar. The official update log separately confirms that resources can be refilled on inactive vessels. The report's exact interface and cost still need verification in the full release, so current-version details are 待确认.
Player-reported Fleet steps
In a Steam discussion about refueling, one player describes three bars at the upper left of the selected vessel: Durability, Hull Condition and Fuel. Hovering over the end of a bar reportedly reveals a box with a cost, and clicking the Fuel control raises the fuel amount. The author had tested Rigid and said an empty tank required several clicks because each added a small amount. This is a dated firsthand report, not a confirmed September 2026 UI specification.
The same player later reported that docking was unnecessary as long as the ship was within a port area. Another commenter discussed the possibility of a tablet interaction while within port detection range. These observations may help a stranded player know what to inspect, but the thread does not prove the exact full-release range or SOS outcome. If your interface differs, use the present Fleet screen rather than copying the old click count.
What the update confirms
The August 2026 Co-op Crew Update added repair, resource refill and equipment upgrades for inactive vessels. This means a ship does not have to be your currently active vessel for the documented refill action. The wording says “resources,” so it should not be stretched into a claim about a particular fuel pump or automatic refuel rule. Check the current fleet or harbour interface for the available action on your vessel.
What to check before a voyage
Look at the vessel's displayed resource state and compare it with the next route you intend to take. If a refill option is unavailable, note whether the ship is active, whether another trade or shift is running, and which port interface you are using. The full-release notes mention clearer feedback when another trade or shift blocks a new operation, but they do not tie that message specifically to fuel. Any stated refill cost or capacity would need current in-game evidence.
Active versus inactive ships
The August update explicitly expanded repair, refill and upgrade actions to inactive vessels. That is useful when you own more than one ship and are preparing a later assignment. It does not say that all such actions can be performed from every harbour or while at sea. If a particular vessel lacks the option, confirm the vessel and location before treating the behavior as a general refueling rule.
The game's career system connects owned ships to long-term progression, and the official site describes a fleet ranging from small boats to cargo ships and tankers. Each vessel may present different resources, but the available official material does not publish a current comparison table. A guide that gives one common tank capacity for the fleet would be unreliable. Per-vessel resource behavior is 待确认.
Resource refill versus fuel
The developer's patch wording is broader than “refuel”: it says players can refill their resources. That may cover more than one resource type, so this page uses the exact documented scope. Herbert's historical fuel-capacity adjustment confirms that fuel is modelled for at least that vessel, but it does not prove a particular interface for every ship. A current screenshot of the fleet menu or harbour interaction would be needed to turn this into a precise fuel tutorial.
Fuel figures and ship differences
An older official hotfix increased Herbert's fuel capacity to 2,000 litres from 1,250 litres. That is a historical vessel-specific change, not a capacity table for the entire fleet. The project has no verified current fuel capacities or consumption rates for other ships. Ship-by-ship refueling locations and resource names are 待确认.
Evidence
The official change log supports inactive-vessel refills and the historical Herbert change. The player discussion supplies a dated Fleet-screen procedure for Rigid. A current screenshot or test is still needed before claiming a universal button, station or price.
