In my case, her ability to make basic comparisons with the Estonia, and applicable shipwrecks. Just staying in the Ro-Ro class of ships suggests there was a problem with key elements of the design. But instead, we are given examples of the Titanic, and ships being sunk with torpedoes, ships hitting mines in WWII, and even the Kursk.
To properly debate this issue there has to be a case of a Ro-Ro ferry that lost her bow-visor in heavy seas, but didn't sink.
There isn't one.

HSFinnish ship designer: "Detaching the bow visor still cannot open the ramp"
Backman Nils-Eric 5.10.1994 2:00 TURKU - Tearing off the visor alone does not cause the watertight bow ramp of the car ferry to open. "The visor attachment is not connected to the bow ramp, and the wave only presses the bow ramp more tightly against the ship's hull, preventing water from entering the car deck," said Martti Skytte, director of Kvärner Masa-Yards' Turku shipyard's ship design office.
Former Wärtsilä, now Masa-Yards is one of the world's leading car ferry and cruise ship builders. Skytte began designing ships at the Wärtsilä shipyard in Turku in 1967. Estonia, the former Viking Sally, was built in Papenburg, Germany. "It was built in the Bureau Veritas category. We have built the visors of the ships to the strictest rating, Norske Veritas," Skytte explains.
He says the bow visor can break in rough seas, but at any point a watertight bow ramp resting on the hull still prevents water from entering the ship. "Provided, of course, that the ramp has been tightly closed. A self-locking ramp may open outwards."
According to video images taken from Estonia, the ramp was almost a meter open at the top. "Then, of course, it has leaked all along its edges."
According to Skyten, it is no longer worthwhile to try to push through the storm on the basis of the bow ramp alone, but the ship is able to search for the nearest shelter in the wind. Estonian contemporaries include Turella and Rosella, built at Wärtsilä in Turku. Skytte was involved in their design as a project engineer: "Their ramps, like other car ferries, were dimensioned to meet the requirements of truck traffic. In the mid-1980s, a tight bulkhead was built on the car deck behind a visor and bow ramp on ships of the next generation, such as Viking Line's Mariella and Olympia.
"Mariella's visor, completed in 1985, was damaged immediately by the storms of the first fall, and the attachment of the twisted visor was strengthened." "Lessons were learned from every experience"
Skytte at this stage being a shipbuilder, must surely know more about this topic than Carl Bildt and Kari Lehtola on Day One.
The JAIC had to invent a whole scenario of the bow visor pulling off the car ramp, yet no-one saw the car ramp open, to come up with the vessel downed like The Herald of Free Enterprise.
Sillaste never saw it open. The two Estonian athletes did not, either.
