ShipShaper rudders control your vessel's turn authority and roll resistance in Tomas Sala's naval builder ShipShaper: Falconeer Chronicles. Depending on whether you place standard steering assemblies, integrated screw units, or specialized diving rudders, rudder hardware alters both your World Mode steering responsiveness and your hull's balance against capsizing.
Recent updates to the game have overhauled rudder physics and placement rules, giving shipwrights access to multi-rudder arrangements, size scaling, and direct handling feedback.
Rudder Configurations and Placement Rules
In ShipShaper: Falconeer Chronicles, rudders attach beneath the stern to dictate your vessel's rotation in World Mode. Through the Cranes, Rudders and Drag update as well as Library Mode, rudder placement offers adjustable configurations depending on hull dimensions.
- Multi-Rudder Spawning: You are no longer limited to a single rudder post. By selecting a rudder and using the horizontal stretch handle along the width of your hull, the editor can spawn double and triple rudder arrangements.
- Integrated Screws: Certain rudder models feature dedicated mounting space for an integrated propulsion screw, combining steering surfaces directly with propeller thrust.
- Scale and Width Response: Rudder scale directly influences steering. Enlarging a rudder increases its control authority over the hull during turns.
- Library Mode Previews: When browsing parts in Library Mode or cycling the item detail belt, rudders display complete mesh previews alongside associated hardware such as propellers and paddle wheels before placement.
| Rudder Setup | Placement Method | Primary Effect |
|---|---|---|
| Single Standard Rudder | Centered on stern centerline | Baseline turning authority determined by part scale. |
| Double / Triple Rudders | Stretch rudder handle across hull width | Multiplies turning surface area across wide hulls. |
| Integrated Screw Rudder | Placed at stern propeller mount points | Combines rudder deflection with dedicated propulsion screw clearance. |
| Diving Rudders | Mounted along the lower hull or keel line | Stabilizes vessel roll and activates the Dive button in World Mode. |
Diving Rudders and Roll Stabilization
Diving rudders serve a dual function in ShipShaper: Falconeer Chronicles. Beyond modifying water flow, they provide crucial hydroelastic stabilization under the game's full physics simulation.
In full physics mode, heavy topside weapons—particularly large turret guns—create severe point weights that can cause narrow or top-heavy hulls to list and capsize. Diving rudders, alongside leeboards (historical side swords), act as roll stabilizers. According to official patch notes and developer demonstrations, the stabilizing force follows two clear rules:
- Depth: The deeper a diving rudder sits beneath the waterline, the stronger its roll stabilization effect.
- Surface Scale: Larger diving rudders apply greater corrective force against listing during turns and crosswinds.
Mounting diving rudders onto your vessel also unlocks sub-surface mechanics in World Mode. Once detected on the ship, a dedicated "Dive" button appears on the interface, enabling the vessel to plunge beneath the waves and resurface on command.
Steering Controls, Propulsion Interaction, and Inertia
Rudder turning in ShipShaper does not snap instantaneously. Steering incorporates physical inertia based on the size of your vessel and the dimensions of your steering hardware.
- Gradual Rudder Deflection: When using WASD controls or interface steering, rudders take time to transition from center to full lock, allowing incremental adjustments like quarter-rudder maneuvers.
- Propeller Interaction: Angling propellers changes rotational speed, and reverse propulsion applies braking force while the hull carries forward momentum. Combining angled screws with proper rudder alignment maximizes turning responsiveness.
- Handling and Stability Stats: The stats display beneath your ship's name provides a 1-to-5 rating for stability, load, and handling. Stability ratings actively calculate your ship's list, trim, deck clearance in turns, keels, and underwater rudder fins, glowing red if the vessel is at risk of swamping.
Frequently Asked Questions
How do I get double or triple rudders on a ship in ShipShaper?
Select an equipped rudder at the stern and drag the stretch handle outward along the width of the hull. As the span widens across the stern, additional rudders spawn automatically to form a double or triple rudder layout.
Why does my ship capsize during turns even with a rudder installed?
Rudders turn the hull, but tall or narrow ships with heavy deck guns can roll over when banking into a turn. To counteract this, add diving rudders or leeboards lower on the hull, widen the beam, or verify that your ship's stability rating on the stats panel is sufficiently high.
How do I unlock the Dive button in World Mode?
Attach at least one diving rudder to your hull in the editor. Once a diving rudder is recognized by the build analysis, the Dive button automatically appears on your World Mode controls.
Do rudders adopt the hull bottom color theme?
Yes. Following post-launch color palette fixes, rudders update reliably within the editor to match selected color themes and lower hull finishes.
