* Failure damages both the [[rope]] and the [[square piece of cloth]].
* Improvement uses [[Blacksmithing]] skill but [[carpentry]] tools: [[mallet]], [[file]], [[carving knife]], [[pelt]] and [[log]].
* Dredging works similar to digging, though you can 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. In order to level a tile to flat, however, one must be over an already-flat tile that is next to the nearby tile that is to be flattened (right-click -> level will appear only on tiles outside of boat and very near).
*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 [[mooring anchor|moor]] your ship or boat before dredging.
*You can dredge all kinds of materials, for instance [[clay]], [[peat]], [[tar]], [[gems]], and [[valrei item|valrei items]].
