Count the quantity the rule actually uses
Redbeet's support answer is about raft foundations, not every visible building piece. It explicitly excludes Collection Nets from the foundation number. A multi-deck raft can therefore look enormous while having a much smaller counted foundation load than a player estimates from total floor area.
- Use the Foundation Counter if it is available in your build; Redbeet's 2022 update says it added this item.
- If counting manually, count foundation blocks only. Keep Collection Nets, upper floors, walls and decorations out of the total unless the game counter says otherwise.
- Write down the number shown by the raft or count, and the number of installed engines.
- Compare your case to the official support chart and check each engine's own foundation indicator before changing the layout.

Read the local check as two thresholds
The checker divides the foundation count by engines and displays the regular 100-per-engine reference and the additional 10-per-engine slow-zone arithmetic described by Redbeet. It deliberately does not derive a precise raft speed from the article's chart. That chart is the source for speed combinations, and your in-game engine display remains an important cross-check.
| Example inputs | Checker classification | Next action |
|---|---|---|
| 150 foundations, 2 engines | Within 200 regular-range foundations | Check fuel, direction and engine indicators if motion still seems wrong |
| 205 foundations, 2 engines | Above 200, within 220 slow-zone reference | Expect slow-zone behavior; compare the official chart before adding an engine |
| 250 foundations, 2 engines | Above the simple 220 threshold | Check the count and add capacity only after verifying the live engine state |
| Any raft with many Collection Nets | Nets excluded from foundation count | Do not include nets in the calculator input |

Separate load from direction, fuel and speed expectations
A capacity result does not diagnose a reversed engine, an engine that is off, or a fuel problem. The Final Chapter introduced Engine Controls that can switch and direct the engines together, but a control setting still needs to match the direction you want. Nor does an extra sail fix an engine capacity issue: Redbeet's support page says multiple sails do not increase speed.
- Confirm the engines are on and their direction is consistent with the intended travel.
- Check fuel and each engine's on-device indicator.
- Use the published support chart for speed cases rather than interpreting the checker label as an exact speed.
- Do not add sails expecting speed; use engine or paddle controls when the raft needs propulsion.

Report a reproducible raft movement issue
The same symptom can come from counted foundations, a slow-zone load, engine state or the selected direction. A report is more useful when those details are separated; other players' Steam posts are leads, not verified fixes.
- Include the game build, platform, solo/co-op and mod state.
- Record the Foundation Counter value or explain how you counted; identify whether collection nets were excluded.
- List engine count, each engine's display/indicator, fuel and Engine Controls direction.
- Describe what changed after one adjustment, and include a screenshot only if it removes private names or world details.

Before you play
- Count foundations, excluding Collection Nets.
- Use 100 per engine as the regular reference and 110 as the documented slow-zone boundary per engine.
- Consult Redbeet's speed chart for exact speed cases.
- Check fuel, engine state and direction before treating a low-speed symptom as a capacity problem.
Frequently asked questions
Do collection nets count toward engine capacity?
Redbeet's official support article says Collection Nets do not count in the foundation number.
Will a second sail make the raft faster?
No. Redbeet's support answer says extra sails do not increase speed; it points to paddling or engines instead.
Does the calculator know my raft speed?
No. It checks two per-engine foundation thresholds only. It does not read the raft or reproduce the official speed table.
Sources & revision notes
Editorial revision: November 5, 2026; not a gameplay test date. The reference notes identify source limits and version differences.
- Redbeet Interactive: Do multiple engines make the raft faster? (Official)
Redbeet support article checked November 5, 2026. It documents the 100-foundation regular range, an additional 10-foundation slow zone, engine speed behavior, raft speed bounds, and that Collection Nets do not count. Use its chart and each engine's current display for exact cases; this guide does not recreate the full speed chart.
- Redbeet Interactive: Will more than one sail make my raft go faster? (Official)
Official support answer checked November 5, 2026: adding sails does not increase raft speed; paddles or engines are the alternative mentioned. Does not certify every later modded setup.
- Redbeet Interactive: The Final Chapter (Official)
Developer's June 2022 update announcement. It documents Engine Controls and the Foundation Counter, but its dated release notes are historical context rather than a claim of current compatibility with every mod or platform.

November 5, 2026: added a source-linked foundation-load diagnostic and local threshold checker; no raft or engine was tested in game.
