Quick answer
The Fishing Hut becomes available when Level 4 ships unlock. The developer FAQ describes the release-version trigger as making your first tier 4/5 ship. Place the hut on a Fish deposit and assign two Greenhands.

Unlock and place the hut
- Spend Principle points until a Level 4 ship becomes available.
- Build or make the first eligible tier 4/5 ship if the hut is still hidden.
- Reopen the Food building menu and select Fishing Hut.
- Place it directly on a Fish deposit inside Pirate Camp range.
- Connect it to the haven and provide two Greenhands.
- Watch the first Fish move into storage.
Use the current production ratio
The Fishing Hut costs 20 Planks and produces 16 Fish per minute. One hut can serve two Stew Kitchens at their current recipe rate, so prove that route before adding another hut.

Fix a hut that does not produce
Confirm the building is on the deposit, inside camp range, connected, staffed, and able to place Fish into open output storage. If Fish exists but the kitchens wait, inspect the warehouse slot and Fetcher route rather than rebuilding the hut.

Common mistakes
- Expecting the Fishing Hut before Level 4 ship progression.
- Placing it near water instead of on a Fish deposit.
- Forgetting two Greenhands or their upkeep.
- Building multiple huts before connecting the first one.
- Sending Fish through a long warehouse chain that starves the kitchens.
What success looks like
The hut appears in the build menu, two Greenhands produce 16 Fish per minute, storage stays clear, and up to two nearby Stew Kitchens receive Fish without recurring delivery gaps.
