    i think the new direction we should explore is co-operating with current sea-steaders, known as liveaboards and cruisers.

    The first liveaboard I know of was Harry Pidgeon, and since then it’s been an ever expanding amount of people participating in both circumnavigating and living aboard their boats.


    in general liveaboards have very little technology on their boats, potentially even lacking electricity, due to difficulty of maintaining electric systems in salty atmosphere.   Also they have relatively small boats, approaching the limit of what Nasa deems sufficient, about 10m^3 per person.


    In terms of the mobile move your house if you don’t like how it’s done locally, it’s not only boats, but also trailers that can do so,  with the tiny-house movement it’s quite viable to have dynamic-residential on both land and sea.  Of course, much like with boats, though not to as an extreme extent trailer and tiny homes, tend to be quite small, with few utilities.


    A basic liveaboard boat for a couple or small family (<32ft LOA)  can be purchased under 10k.

    This is a market that is so saturated few manufacturers can profit making boats in that size.

    Boating magazines are chalk full of huge boats, as much as 65′ LOA, costing hundreds of thousands,

    sometimes over a million.  Noteably the more expensive a boat, the more expensive it is to maintain.


    I think before we start thinking about making seasteads that float in the middle of an ocean,

    we should make plans for utilizing some of the many uninhabited islands in the oceans.

    Typically the problem with uninhabited islands is lack of fresh water,

    so figuring out a means of producing copious fresh water is necessary,

    quite-obviously it would have to be without electricity, as that would quickly break surrounded by ocean as it is.

    So some kind of simple passive distillation system would have to be used.

    and then can start building some kind of resort for people to visit,

    potentially with food sources and product manufacturing to make it self-sufficient.

    Many of these islands are only loosely held by their governments,

    so it would be possible to get independence once a population is established.

    much as many pacific islands have in post-colonial times achieed autonomous status.

    one of the best things for a storm, a more tried and tested version than having a wing shaped deck,

    is using a sea-anchor, which works best with a canoe-shaped stern, then can have bow face the waves.

    otherwise it’s rear-sea-anchor and running the risk of getting pooped if the waves crest too  high,

    then have to run with bear poles at diagonals to the waves to slow yourself.


    So if possible is always best to have canoe shaped stern, as bow anchor is just so easy.

    if you can sail into dock, then save your fuel, and the environment.

    ideally of course, you would not use an engine at all.

    it’s really a waste, if y

    if you want solid superstructure on top can look at wingsails, which look like air-plane wings on boats sideways.

    Looks like we be having a mild reunion.


    I’d like to inform the newcomers, that a) artificial islands only refers to things stuck into the ground,

    whereas what we may term “floating islands” are really just gargantuan vessels.

    2) Economic co-operation zone refers to commercial activity,

    and not to personal or self-sufficiency activities.


    Also we can’t live completely detached from the rest of the world,

    vessels require a lot of upkeep, and definitely some imports.

    So there would have to be trade.


    Typically as long as we are providing more benefit for the locals,

    than we are detracting through our activities,

    then they will encourage and support our activities.


    If it seems that we are benefiting them,

    but they aren’t appreciating or even taking advantage of us,

    then we can always move to nicer place, as we are indeed vessels.

    oops. I had an extra 0 in my spreadsheet.  so actually the thickness of 6cm is more appropriate instead of 20.  and that would mean the large one has depth of 5.35m without any extra weight. also the cost is much higher,  $24k for the small one, and 1.5mil for the large one.

    In any case after designing island stead for a while… I’ve decided to switch over to boat stead as it’s a bit more useful.  Though likely we’ll simply buy a used boat to start living on the water.

    Mostly a Seastead would be looking at farming aquatic vegetation and animals.

    For instance with the Pillarstead design I have there is significant underwater “seafloor”,

    on which various seacreatures can grow,  which will attract fish and larger aquatic life.


    I’m considering a new design more like an Atoll,  and then can farm various aquatics inside.

    Could even have a no engine inside policy to minimize the pollution and such.

    Also preventing non-locals from fishing our hard earned seafood crops.


    We’d have to start with the vegetation of course,

    especially micro-algaes such as isochrysis galbana (DHA), tetraselmis (DHA+EPA), nanochloropsis (EPA),

    can also introduce macro algaes,  red gracilaria, brown kelp,  and other edible seaweed.


    In terms of animals like stuff, there is plenty

    various plankton copepods, amphipods, rotifiers, krill, shrimp

    and of course the usual boat dwellers barnacles, limpets, mussels, oysters,

    and some motiles squid, crabs, lobsters, sea cucumbers, maybe even some edible jellyfish.


    Of course various pellagic fish would be great, anchovies, sardines, herring,   carp

    if we have superfluous amounts we may even be able to support some larger fish like cod, perch and pike.


    Though yes, assuming it grew large enough to support soil, or we have some walkways and such,

    then it would be possible to have mangroves, grasses, mango’s, coconuts, pineapples.

    Then we’d have to introduce the food for land animals, grain, grasses and insects of various types.

    At which point we can probably introduce the green junglefowl.


    Something we could introduce and potentially raise our eco-friendliness points by are some endangered species,

    though we’d have to set up a good environment for them first of course.

    such as the Salt Marsh Harvest Mouse, the Fishing Cat.


    If and when the Salt Marsh Harvest Mice have become prolific,

    can introduce the Swimming Cat, Turkish Van, which would happily prey on them, and fish.


    Crab-eat macaques are also an option, they may also be trained to pick coconuts and such potentially,

    though they may pose a thread to the endangered animals, and aren’t particularly meaty or anything.


    we could also make habitat for seabirds like Boobies, which like to land on ships.

    and Cormorants which can be used to fish.

    In temperate water, Penguins are also an option,

    such as the Galapagos Penguin or Humboldt Penguin.

    Attracting seals may also be an option.


    Mostly though,  the diet would be seafood, low on the food chain,

    and that’s really the healthiest kind anyways, so should be good.

    Yes, you can promote it.

    The best way is of course by being the change.

    You can have a boat even in winter by having a bubbler or water agitator,

    it will bring warm water from bottom, and melt the water at the surface.



    People use agitation fans even here in Toronto,  Canada where we have fresh water and it freezes in winter.

    Not sure but it might also work in St. Petersburg, though can go south to Black Sea as well,

    Alternatively you can try the east coast of Russia, where it doesn’t freeze nearly as much due to Pacific.

    Sea of Japan may be a good place, as there are lots of kinky weird fetish people in Japan.

    If you get a shore-side property in the area, can start building seastead islands and float them around.

    Then again if incoming ships use anti-fouling,

    I guess it would defeat the purpose of having pristine interior waters…

    so could just have a simple-c with gate,  or else force anti-foulers to dock outside :-S.

    anyways that would be up to the individual c-colony ha-ha.


    oh ya, I guess depth would be greater than 1.728m considering people will bring many tons of stuff with them.

    the 52m width of the seafloor, should allow for it to be comfortable for all but a rogue wave.

    Profile photo of elspru

    If scaled up to have 100m^2 per floor or ~1000square feet, 8 floors,

    then shell costs about half a million,  and has 1/4 hectare or 2/3 acre of seafloor ballast.


    though if it’s as is now, water depth will only be, 1.728m,

    likely will have to have a thinner section, perhaps several mini pillars,

    holding it up to achieve the 3m depth of most marinas.

    Alternatively can increase acreage…


    though I’m starting to think perhaps a c-shaped islet with a cup interior would be good.

    Especially considering how polluted much of the ocean is,

    can have locks to purify water surrounding incoming ships,

    so interior lagoon could have relatively pristine water.


    Also the interior cup would give the required submerged structure for stability.

    Profile photo of elspru

    So noted that common wave height is 8m,

    and previously read that a boat can be capsized by a wave 55% of it’s waterline length,

    I’m hoping it’s a significantly higher percentage for underwater length.


    anyways updated the design,  to use pure ferrocement bottom, extended to 18m diameter.



    Also it’s convenient as it means can have docks going outwards about 7m long.


    This means have about 250m^2 of seafloor, about 1/16th of acre or 1/40th of hectare,

    which seems like a fairly decent chunk for a 1 bedroom.

    In reality will probably have holes in the  ballast plate to allow for easier repairs, and light penetration.

    Potentially a slice could even be open for deep keeled boats. though they could come along side to a dock.


    It’ll probably act as somewhat of an artificial brakewater,

    am considering making it as a downwards facing cup to give it more geometric strength,

    while also making it more like a shore with an inclined beach of sorts.


    average waveheight in most of pacific in atlantic is under 3 meters,

    so it should be sufficient.  even if it does get flipped over (however unlikely) it’ll quickly return.

    Waves might wash over it, and some will definitely crash into it, but outside of storm season should be okay.

    can repair it during the calm seasons.


    The design is scalable, so should be able to get much bigger.

    though I think it’s essential that at least the first prototypes are accessible.

    Most difficult part of this would probably making that base plate,

    it weighs over 3 tons.    If made in hexagon, can interlink them as modules.

    Hey, so I updated the design, to increase the amount of submerged section.

    A big disk as you mentioned, about 11m in diameter. can be used for buoys, or dock fittings.




    The bottom is green as it’s planned to allow bioaccumulation,  using it as a water garden of sorts.


    The green ballast section, which shall be around 40% iron as ballast.

    assuming interior stuff weighs at least a ton,  and up to 4 tons, can use less ballast if more weight, though unlikely.

    anyways so it has waterline at depth of between 40-60% of it’s height allowing boats with drafts of up to 2-3 meters respectively.


    Walls are 20cm thick.


    price of shell 11-thousandish.

    So get a sailboat to live on, and you’ll be on your way to seasteading.

    Profile photo of elspru

    that wouldn’t really work, as if you had cables that are so long, you’d need very high voltage, and likely even alternating current, to get any of that electricity to the other side,  besides that you might have sharks attacking the cables, as they are electro-sensitive.

    Much better off producing and storing hydrogen on the boat, there are ways of compressing it passively, for instance by using it to pump barrels of water upward and such.
