Seastead

A seastead is a structure floating on the ocean that people can live on in deep water outside the jurisdiction of existing countries. Since the focus is just living on the water, and not getting anywhere quickly, a seastead design can sacrifice speed through the water to achieve lower costs per square foot and greater stability than a boat/yacht/ship of similar price.

There are several different lines of thinking on good strategies to get to real seasteads. The main ones seem to be:

Why/Strategy	Example	Example
Single Family Seastead	Tension Circle House
Breakwater Bay	Tension Circle Marina
Floating City Seastead	Clubstead
