My question centers more on expansion. Let's say I built a floating concrete-dome house and floated it up, would it be possible to moor it to the ship somehow, using the ship as a hub from which to expand from, in essence. We'd be renting your stable mooring in essence.
+1 That's the real way to build a community: use the ship as a core unit that supplies power and Internet, around which a stable constellation forms. The owners of the core dictate "building codes" by virtue of requiring certain seaworthiness and navigation aspects for any core connections.
