Based on Depth
- Above Surface (code: A)
The habitation can be above surface or might have a deck below surface.
- Midwater (code: M)
The habitation is located in midwater. The purpose is to provide faster access to lower sea level without having to go to the surface or act as a relay post between Surface-stead and Shelf-stead. Some may use buoy to give marking of their location. Midwater type is relatively mobile since it must have buoyancy tank and can adjust its depth.
- Floor / Shelf (code: F)
The habitation structure is located on the seafloor / seashelf. Who wants to be in the sea floor? Perhaps someday we need to harness power from under sea volcano / sea vents, therefore we need a base near such location.
The code is being used for Seastead mapping. So when you already in a GPS coordinate of a Seastead and can't find anything in sight, perhaps its underwater. The code can also be changed when a Seastead change its depth for example an A-stead called Seamonkey (A) is submerged to mid-water so now its Seamonkey (M), easy right?
Based on Production
The seastead produce tangible goods.
Water treatment facility
Waste recycling facility
Energy Generating Station
- Non - Production
The Seastead is mainly for habitation or storage only. Service or non physical (virtual) industries or spesial purposes acivity can sometimes suits this category.
Based on Self Sufficiency
Seastead with gardens and or farms that provides food to its inhabitants. This stead also able to manage nutrients and energy available in its surrounding either its the fish, wave, sunlight, etc.
This type unable to suffice the food and or energy required by its inhabitants. Even if they have gardens and or farms, if the output is not able to feed the consumption needed by its inhabitants, it is considered supply-dependent. Simple equations, more people to feed likely cause the need of more supplies.
Based on Mobility
The Seastead is capable of moving due to availability of engine,
- Limited Mobility
The Seastead has no engine parts, however it is possible to move the seastead with the help of tugboat etc.
The Seastead is fixed to something like the seafloor or reefs and therefore it is not possible to move the structure.
