A problem for seasteading as a nascent movement is the lack of access to places from which to build, model, and stage attempts.
Most commercial ship yard are not interested until the concept is proven. Most private land is inaccessible. Public lands have restrictions on private use.
Once concept for an incubator site is described here.
Potential requirements for a Seastead Incubator/Seastead Base (SSB):
Access to water of minimum depth
Launching facility and equipment (cranes, gantries, mobile lifts, ramps, lock-and-dam dry docks etc.)
Access to the ocean (clear of bridges and obstructions)
Access to materials/delivery
Access to utilities (water, electricity, telecommunications)
Adequate space for ship-building type activities
Appropriate zoning for seastead-building activities
Secure storage for tools and materials
Potential Differentiators for Seastead Incubator
Shared machine shop/tools rental availability
Particularly beneficial locations for particular projects
Shared library of design/engineering resources
For-hire marine services
On-site living accommodations
Recycled/re-used/reclaimed marine materials/gear/equipment from a scrap/wrecking yard or retail marine exchange shop
