The cabin appears to be dead center, hanging a bit like the gondala from a blimp.
LOOKS LIKE THE BOTTOM FELL OFF SANTA'S SLEIGH.........
Yeah saw that. Many advantages to that. As a sailboat owner I know the disadvatages of a boat being "in" water. Water is your enemy. Maybe if the footprint was smaller.....but for the size of the "cabin" compared to the footprint....totally nonfeasible.
hang some lasers off of it
its got independent suspension to isolate it from instabilities in water so you can fix on a target
there is really nothing there for someone to target and effectivel hit......
Frankly, I prefer the first generation alternate use posting #21
