you could always motor on down to east Africa
Actually I read some more articles and this particular vessel has been cannibalized to keep other ships in the same class (Ark Royal?) operational. So it comes without serviceable engines, pumps and whatnot.
Not an irrecoverable situation of course, but something to consider for your business plan.
Mooring it somewhere should not be a problem though, if you rent a big enough tug to get it there. Heck, you could probably even anchor it out to sea somewhere. Maybe halfway between Calais and Dover, so that nobody needs to be out of gliding distance from a suitable landing spot anymore while crossing the Channel. Who knows, you might even be able to sell tax-free fuel that way.
Obviously restaurant and sleeping facilities are all on board as well. I feel a GA magnet starting to appear here.
