Sorry; hit "send" by mistake.

Well, guy is an artist, so you never know. But let's assume there is ballast in that bilge. He may still get seasick every time a dinghy rows past. Sort of like living in a very slippery rocking chair."

I would have thought that this hull shape would be particularly immune to rocking from wave influence, not the opposite.
Agreed, I also noticed in one of the shots in the travellift, that it has external ballast that forms feet.  It will likely wind up sitting on them pretty often in its protected anchorage.

Cuteness aside, the operative word in the web page is "tethered."  It's not a ship, or even a shantyboat it's a "floating home." Stability curves assume a free floating craft--I think in the extremely protected water, with a few lines securely attached, that I would certainly spend a night (or a month!) on her.

Whack-boing! It's dub!

Did you see how high it floats?

What I was implying was that there is no reserve buoyancy because the section is perfectly round.  This means that as the "hull" inclines due to the weight shifting from side to side there is no righting moment from the deeper side puttiing more force upwards than the shallower side, because there is no deeper side.  Sailboats with round bilges stay upright because the lead is well below the center of buoyancy and swings far off center to oppose the moment from shifting weight off
 center inside the hull (or other outside upsetting forces).

It all depends on how much ballast is used.

I assume that she has either ‘keel’ or ‘box-keel’ or at least a fair bit of ballast incl. batteries.

So, that would preclude having the whole egg begin to spin...

Which leaves the old Hamster-in-the-egg routine... no yoke intended... 
(I expect you to laugh for about a week !)

This would mean doing a 1/2 or 1/4 section weldment to bring inside, bolt together, and then put in/onto four bearings on her sole to allow that ‘wheel’ to spin inside the egg - as I was saying ‘the-old-hamster-in-the-egg-routine’...

Of course, I have always considered SuperBrick quite normal.
