I recall this idea had been floated (pun intended; see what I did there? ) about 20 years ago. I thought the idea had died of lack of interest given the projected cost.
If they go ahead .... I hope they put enough lifeboats on this time. Radar would help, too ......
Apparently the two forward funnels (smokestacks) are dummies. Part way up in each one will be observation platforms, and the top of each will house radar blisters.
There's a semi-hidden lifeboat deck with 18 motorized lifeboats, each supposedly holding 250 people (!!). That's 4,500 people. The traditional-looking lifeboats on the upper boat deck are reproductions, for nostalgia/authenticity. Not sure if they'll be functional or not.
