Personally, I shuddered when I watched the video. Miles of teak deck, more miles of things that want wax on them once a month.
As to docking, the Palmer Johnson 120 I visited down in FTL a few years back had twin screws plus bow and stern thrusters. You could wiggle that thing with just a couple of feet of clearance on both sides.
Sway, if you go hang out on that thing, make sure you take your buffer. You'll need it!
