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.

I like this. These ships also won't be subject to vehicle restriction violations...

... Now that I'm actually forcing myself to use amphibious vehicles (and take extra steps to inhibit a certain truck-related glitch that makes them impractical...), I double support this. Amphibious trucks are great, but they look a bit silly driving on the ocean's surface as if it were bumpy but solid land.

And a proper dredging ship probably wouldn't have the "only 5 tiles deep" restriction that the amphibious excavators have, would they? That'd allow you to use dredging to get at this bauxite (and other, similarly-placed resources) rather than having to build a massive island around the island, then crater it to reach:

On the other hand, the whole "Amphibious" argument does have weight, since its primary purpose was to enable over-water bridge construction. But that could use a barge, pretty sure real bridges do that kind of thing, and for creating an LZ on another island, that's what you get a landing ship/"ferry" for, to ferry non-amphibious vehicles to some other land to do work. I could absolutely see the current amphibious models being used for "all-terrain" vehicles that could handle boarding (and disembarking from) ferries without a proper terminal, and may or may not also be able to handle steeper/rougher terrain than other vehicles. If you want to cut a ramp into a rock face from the ocean, the excavators might just have to work directly from the ferry boarding ramp, without actually disembarking.

That ferry would tend to have a depth requirement, which could be met by dredging just offshore beforehand.
