Replace Amphibious Vehicles with Dredging Vessels

Devs, please consider adding small and large dredging vessels to the world map, like normal ships.

These vessels could include a shipping terminal that allows rock and dirt to be loaded onto or removed from the dredging vessel. The vessel could then dredge a selected area of shoreline or shallow water to a specified depth.

It could also dump rock over the side using an attached crane, with a limited maximum height above the water. This would allow players to reshape shorelines, deepen harbors, create channels, or reclaim shallow areas in a more realistic and useful way than amphibious vehicles.

The Ships are more realistic than fantasy amphibious vehicles, and they won't have to travel all over the map looking for fuel.
The vessel must be in the water, not on the shore.
