A free mod for Valheim, by Floki.
Floki’s Dock is a simple boat dock.
This is a simple dock for shallow water.
They are 26 tiles wide and 11 tiles long.
The supports only run 1 to 2 beams deep.
You may need to disable build damage when spawning these in until you can set new beams if they are in a deeper area.
This is now compatible with the BepinEx mod!
This works with the BepinEx mod, which allows you to place an anchor in the world, and then spawn a boat to it.
If you want to build something like this, you may need to use the advanced builder, which has an xyz axis and rotation.
