About ShipTweaks
From ThunderstoreConfigurable Valheim ship speeds with rowing force multiplied by players on the ship.
ShipTweaks
ShipTweaks is a standalone Valheim BepInEx 5 mod for configurable ship speed and rowing behavior.
Status
This release has been tested in multiplayer, but ship physics can still vary with latency, world load, and other ship-related mods. Back up important worlds before using it on a long-running server.
AI Disclosure
This mod and Thunderstore package were created with AI assistance. OpenAI Codex was used to help generate code, package structure, and documentation.
Features
- Configurable multipliers for rowing/reverse, half sail, and full sail.
- Optional normal hard speed limit and separate thunder/storm speed limit.
- Normal rowing/reverse force can be multiplied by the number of players on the ship.
- While rowing,
xPlayerCountis shown next to the ship speed icon. - No seat, W/S, or extra oar mechanics.
- PaddlePower-compatible approach: existing ship values are changed only temporarily per physics tick.
Configuration
After first launch, edit:
BepInEx/config/domen.valheim.shiptweaks.cfg
Simple settings:
RowSpeedPercentHalfSailSpeedPercentFullSailSpeedPercentMaxSpeedLimitStormSpeedLimitPassengerRowingEnabled
If PassengerRowingEnabled = true, rowing uses:
Rowing force = vanilla rowing force * RowSpeedPercent / 100 * players on ship
Example: RowSpeedPercent = 100 and 3 players on the ship gives 3x vanilla rowing force. RowSpeedPercent = 150 and 3 players gives 4.5x vanilla rowing force.
Default values:
RowSpeedPercent = 150HalfSailSpeedPercent = 125FullSailSpeedPercent = 150MaxSpeedLimit = 0StormSpeedLimit = 0PassengerRowingEnabled = true
For MaxSpeedLimit and StormSpeedLimit, 0 means ShipTweaks does not apply an additional hard speed limit. It does not mean 0 m/s. Valheim still limits ships through physics, wind, mass, and water resistance.
Vanilla reference values:
- Raft: paddle 1.6 m/s, half sail 1.7-2.2 m/s, full sail 2.2-3.1 m/s
- Karve: paddle 3.14 m/s, half sail 2.8-4.8 m/s, full sail 3.9-7.0 m/s
- Longship: paddle 3.16 m/s, half sail 3.6-6.7 m/s, full sail 5.0-9.75 m/s
- Drakkar: paddle 2.50 m/s, half sail 3.3-6.2 m/s, full sail 4.65-8.9 m/s
