Hi, I don't know why I can't place Cargo and Tank ships, while the normal boat has no problem. I don't know if it has conflict with the other mods, but when I have those two types of boat in my inventory they behave like normal items and not as a placeable entity. I have installed all Pyanodon mods, Darkstar Utilities and Factorio Plus Plus. I have just noticed that the normal boat has the energy consumption description, while the other two has just the storage size description.

Hey, the cargo and tank ship need to be placed ontop of the waterways- just like trains need to be placed ontop of rails.

Oh, I didn't realize that, thank you very much!
