    See [the blog post](http://seasteading.org/stay-in-touch/blog/3/2009/01/21/engineering-report), or just [read the report PDF](http://seasteading.org/files/MIandT040_08_R1_Seastead_Exec_Sum.pdf) – 50 pages of engineering information!

    I just tried to download this PDF and page 8 was missing, is there anything on page 8?

    That’s the secret stuff about that bakini-clad women handing out bazookas.

    There is no fate but what we make for ourselves. Each to his fate.

    Downloaded it again and it seems complete, but there are blank areas which may have lost their text/graphics.

    The Study in my opinion was, for the lack of better words, Weak.
    I’m gob-smacked, at how unprofessional that report was.
    It seemed as if some one had gotten a template & just filled it out with thoughts, idea’s, & nice pictures.
    Not what I would expect from a marine engineering company.
    Also, the dangerously limited aspects of marine environment hazard, perception was deeply concerning.
    The lack of scientific thought given to the general hazards associated with the marine environment was shocking.
    Very little was mentioned about safety & sea survival systems.
    I hope no one paid for this.
    I liked the pictures though.

    a few questions reagrding the wave height/period distributions on page 17/18:

    – assuming i have some way to simulate the behaviour of a given sea stead in a regular/sinusoidal surface wave with a given amplitude and period (CFD or so). if I test my seastead against the highest waves encountered for each period (and interpolations) and it survives or behaves well, can I assume it is also going to behave reasonably well in a combination of these waves (as you would encounter them in the real ocean)?

    – where can I find this sort of wave height/period distribution for other parts of the world? I would be interested in 100 year worst cases or so for very calm waters, e.g. the irish sea or something between the islands of denmark… It’s easy to find the *current* state from met offices, but the worst case to plan for seems harder to find…

    thanks robert


    Patri, the most important thing about make seasteading happening as a “society relevant event” is to make it available for those who can not afford 120USD/day as cost average. The segments that can afford that are already out there doing some kind of seasteading, the cruising industry, the oil/gas industry, marine load terminals, mega yacht industry, they all have already people “more or less permanently living on the ocean” .

    Seasteading as suburb development will only happen if you can do it at suburban housing cost.

    A “glorified semisubmersible drilling platform combined with a tension cable bridge” seems to be a design way to expensive to come even near to the objective of “affordable for the average guy” – Why not making a simple concrete shell flat raft which is much more affordable.

    Anything in there that’s actually relevant to proper seasteading, or is it only applicable to “ClubStead”?

    At the moment, I’m quite interested in either buying a secondhand ship, or building land in shallow areas. Or maybe a combination of the two – could we permanently anchor an old cargo ship in Doggers bank?


    Seasteading is to Boat Living what Traction Cities are to Vandwelling – simply a matter of scale.

    Of course that you can drop the hook in Doggers bank….But, have you ever been in the Northern Sea? I did. Once and my last. I’ll take any other ocean or body of water to seastead before that.

    P.S. Get some good life insurance, warm clothing, plenty of vodka, some open minded women, plenty of drugs (valium will do), a lot of books and plenty of cash to pay for heating fuel. Good luck and God have Mercy on your Soul.


    as always i would advocate for small scale testing – take a yacht and anchor it 20 days in Dogger Bank – i prefer the caribbean as testsite – anchoring in front of a tropic island for 20 days really can work as a lifestyle – many people do it …a half permanent “yachtie town” is a comon view at many spots in the caribbean. As said before the spot selection is PARAMOUNT for “living on the water”.

    Are those people not doing something that should be considered the first step of ocean colonization ? Is a floating marina development that allows to raft up common yachts a seastead?

    A floating marina development can be considered a seastead. Thats how I got int seasteading. Back in “97 I was managing the maintenance for the 800 slip Kona Kai Marina & Yacht Club in San Diego Ca. One morning, I was a bit early for work. I was seeping on my coffee in front of the marina office, which was situated on a bit of a higher elevation relative to the water level, when I noticed the tide coming in, All our slips were brand new, float on concrete docks. In the next half hour, everything was up 6 feet. All the 800 boats, the slips, the whole marina. Well nothing new to me, but then An Idea popped up. What if such a “marina” can be build inside the open “lagoon” of an “atoll” shaped breakwater? This “marina” can then travel around the word, “carriyng” al the boats while they are floating in their slips, sheltered by the breakwater? @ the time, I was living aboard a small sailboat, a 27 footer, a nice coastal cruiser but not a passage maker. If such marina-seastead would have existed, I would have gladly joined, since, if it would have gone to Hawaii, I could have been on my 27 footer for the passage, in my slip, bbq-ing, smoking pot and drinking rum with my buddys. (Hey, I was young, ok! – and actually not a bad idea in general :-) @ the time I was paying $7/ ft/ month (yeap,..the good old days, guys!). But I would have gladly pay triple that amount just to be able to cruise all the Hawaian islands on my 27′, 3 weeks later, when the marina-seastead would be anchored in the ‘Au’au Channel (between the islands of Lanai and Maui)- for example. This “marina-seastead” can then spend the whole summer there. Some of the boats might just stay, some work around the islands to save a bit more cash. For sure some of the local sailors on small boats there will dig the whole idea and replace the one who are staying. When ready, then is time for passage to South Pacific, to the Marquesas and beyond. A lots of my liverboard friends, then, said that was an exellent idea.

    Now, while the whole traveling would have been nice, and achievable on a big budget, for beginners like us, with $0 budet, for now, its just a pipe dream. But still a good dream if the whole thing can be started small, and then build up from there.

    Yes, I think starting small next to a Caribbean island makes sense. Here is one idea:
