    And the less waves, the smoother those expandable gangways can work.

    So could be cheaper to have a breakwater than reinforced or longer lasting docking?

    Greetings everyone. This is my first post here @ seasteading, though I’ve been watching for a few days and have ready every single post and followed every single link in more than 10 threads. Those links are a great resource, btw, thanks. I found STI while looking at large luxury yachts I will never be able to afford, such as the 70 SUnreef Power, lol. Which are pretty much seasteads, the 70 even has expeditionary configurations which are designed for long term use. Of course it’s a luxury yacht and costs several million Euros, and is not self supporting. I had also been keeping a loose eye on the Freedom Ship, which is looking like it will probably never be built, though I like the idea in theory. I think some of these seastead ideas are even better than the freedom ship, at least they seem closer to becomeing a reality.

    I’m choosing this particular thread because it seems to be progressing much faster than many of the others I read. You all seem to be discussing real world application, and working together to get beyond boudaries. You’ve discussed a wide array of topics and still managed to keep momentum and not get lossed in the saus as they say.

    @ Octavian: I think your raft-up idea is great, it’s the way I envision true seasteading. And your post on page 2 of this thread is very well put.

    I think you’re right, that once people like Will get their seasteads up and running they should meet up somewhere. There should at least be a “seacon” where seasteaders can meet up for a while once a year, or perminantly, or whatever and share their ideas and experiences. I also love your idea of building more seasteads at sea, if the logistics aren’t too much of a nightmare. I would like to add that I invision the raft-up idea more with a larger seastead in the center, with other smaller vessels around it, much like The Raft in Neil Stephenson’s Snow Crash, centers around a modified aircraft carrier. Perhaps the floating breakwater could be the larger center (or anticenter).

    @ Will: What is the timeline for getting some of your seasteads up and runing? You said you are building more than just the submarine design, do you have any pictures of any of those? How much does the larger (grey) sub displace? I think I read it somewhere but I cin’t seem to find it now.

    One thing I would like to contribute to is the system used to connect the different components. You guys are skirting the issue pretty well, but haven’t gotten into much detail, other than to use some form of breakaway technology, and bumpers. I don’t much care for the bumper idea, they’re unsightly and wear out very quickly, and I feel that intentional breakaway is a must. If you just let the sea break you apart, then once you’re apart it will bash you into eachother. Especially if you have 10-20+ different vessels lashed together. I have seen a few of the other threads where people have thought of using hydrolic pistons to generate electricity, and use them as part of a break water. I think that should be implamented in rafting together as well. Much like the telescoping gangplank, have telescoping connectors connecting each of the vessels to eachother, but with a hydrolic piston that allows enough movement for rough seas without breaking and keeps the different pieces from bouncing into eachother. They could also generate small amounts of electricity at the same time. Also have it so that these connectors are easily (and securely) connected and disconnected at will, for storm avoidance, or just to move the raft into a different configuration. I would also thing that have full 360* movement (verticle and horizontal plane) if only to a limited degree would help to keep some of the different forces from acting too strongly on the mounting points as it would if you only had leteral or verticle motion as some do. I think this type of connection, could be easily standardized so that all seasteads, regardless of size or shape could attach to eachother, then you don’t have to worry about who is square and who is round and whatnot. and the more vessels you hook together the stronger and more stable to whole becomes.

    I also like the idea of having a wall around the outer edge like the Water World design. I think it would be a great idea to make a concrete floating breakwater where you could put some of the supporting industry on, such as Will’s shipyard and such. Then you’d have a calm lagoon in the center for smaller rafts and works in progress. Seasteading is such a cool venture, it has no limits, no rules (other than seaworthiness is probably a good idea ;-), and is only limited by everyon’e collective imaginations.

    I truly hope that you guys work past all these little issues, get your boats afloat (or submerged in Will’s case), and live the dream. It will be a while for me, but I hope to someday join you as well. I plan on being a very active member of these forums, and may even be changing my major into more of a naval engineer/architect instead of the more broad engineering I am heading towards at the moment. I’d like to be a part of this

    The first hull is 20 tons displacement, the second 200 tons, we also have a project to scale the rion antirion plate down to family seastead size – what we have so far is a 2m diameter plate that can float with a man on top. We expect to come up with a plate seastead like the lens-stead in photo nr.5.

    A further project is dedicated to square chambered flat floats like the nkossa barge (photo nr.6) – again we are scaling it down to family island size – and have a 8 cube platform of 2X8 meter already tested.

    Our development funds are low at the moment – so we will have to focus on one or two of the projects and need to get money out by selling some of the pieces to enable us to go ahead with the development. As always in R&D timelines for the projects are quite uncertain. But we are kind of “in obligation” to get something sellable out within two months or funding (provided by henrik kindblom) is running dry.
