I would be a nervous wreck owning that! I would be constantly worried about attacks from pirates! Unless you can get it to Monaco and just keep it moored there to show off a bit, then that would be great. But I certainly wouldn't feel comfortable riding around on the un-policed ocean waves in it!
Not wishing to hijack your thread, can I point out that like the idiots in my "I wouldn’t trust these idiots with a rowing boat" the person who buys this does not need to have any qualification whatsoever to take this vessel to sea.
Just think of the damage/mayhem it could cause if not handled intelligently!?
