I have never personally been involved in approving side-by-side ocean towage, but I believe it has been successfully performed with near identical scrap ships without overhang.[/QUOTE]
You appear to be basing that comment on the Reddit page you link and an almost identical comment there linking to a photo of the Tug HANSEAT towing two old sealand sisters ships. But they were reportedly only towed Together to clear the harbor with assistance and then towed in line astern.
