Not sure where your information that n8 was supposed to run Meego comes from, but I remember working with the Nokia s60 team already early 2009 and they were using n8 protos at the time. It’s definitely possible that there were two parallel projects though.
On the other hand, Maemo, the predecessor to Meego, required a pen-like pointer to comfortable use at the time as the UI elements were designed to be small. Only after they completely overhauled the UI (and renamed the Linux based OS Meego) it could have worked on the N8.
I’m not a ship engineer but I do know that ships are not built to be suspended from the ends. I guess in the worst case the hull breaks which would mean the canal to be blocked for quite a while.
