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.
