It was just a little wider river crossing, no need for special ships.
Peter Fleming mentions the use of railroad ferries to bring the tanks,
other methods like "Dr. Feder-type concrete barges" and Krupp's
"Lendkreuzer".

Lubber's thinking.

"Another unlikely project was a proposal by Gottfried Feder, a Nazi
official who was a civil engineer by training, to create what he
called a "war crocodile" for use in the anticipated invasion of
England. Feder's brainchild, as described in Ronald Wheatley's 1958
book Operation Sea Lion: German Plans for the Invasion of England,
1939-1942, was a an immense amphibious blockhouse of ungainly
proportions - 90 feet long, 20 feet wide, and 12 feet high-made of
concrete, which could move across the water under its own power and
then crawl ashore on caterpillar tracks to disgorge either 200
soldiers or tanks and artillery. The German Naval Ordinance Office had
serious doubts about whether the crocodile's slender concrete body
would withstand the vibration of an engine powerful enough to move it,
but nevertheless, according to William Shirer's 1960 book The Rise and
Fall of the Third Reich, the crocodile actually was discussed at
length by Hitler himself before being discarded.

German arms maker Krupp dreamed up another immense vehicle, the
Landkreuzer P. 1500 Monster, by placing an 800 mm Dora artillery
cannon-the sort normally towed on a railway car-atop a giant tank
chassis powered by two to four U-Boat engines. The Monster, as
described in My Tank is Fight! Zack Parsons', Mike Doscher's, and Josh
Hass' 2006 book on improbable World War II weapons, would have weighed
in at 2,500 metric tons, served by a crew of 100, and plodded along
the battlefield at six to nine miles an hour-making it a pathetically
easy target for Allied aircraft. Albert Speer, the Nazi minister for
armaments and war production, worried that the Monster's sheer size
would appeal to Hitler, and reportedly forbade Krupp to build a
prototype."

Tell me again about how they were going to build these devices, get
them into position, move them accross the water, and then support the
troops they had in them? All without opposition?
