A Dredge
Total materials
  • Dredge (4.50 kg)
Skill and improvement


A dirty sack with four metal blades along its rim. A rope is attached to it. The idea is that you drag it along the bottom and gather mud.

The dredge's main ability is to dig from below water level. Dredge quality and digging skill affect the maximum depth you can dredge. To dredge deeper than 8 dirts below water level, which is a shovel's limit, you need to be on a boat or ship.




Dredging works similar to digging, though you must be embarked on a boat or ship to dredge. Move on top of the corner you want to dig at, right-click the boat or ship you are on, and select Dredge. The dredged material appears inside the boat.

On bigger ships you may have to embark as passenger to get the option to dredge, because as the commander you might technically be too far way from the boat to use it. It is also a good idea to moor your ship or boat before dredging.

You can dredge all kinds of material, for instance clay. However, clay, peat and tar tiles will only lower if the corner you are digging at is close to some terraformable tile type.

Flatten or level

A dredge can also be used to flatten or level terrain. You must not be embarked on a ship to have this option.


  • A dredge can hold, for example, 2 piles of dirt or heaps of sand (40kg), or 36 clay (72kg), before it requires emptying.
    • When dredging, there must be space in the dredge and in the ship for the materials you would acquire.
  • You may not dredge stone.
