Also, if anyone wants to build a seastead model and sent it to me in Anguilla to test in real waves I would be happy to do so. I have nice clear warm water all year round. I have easy access to many different beaches and can always find one with the right size waves to test a model on. I have 4 boys who love to go to the beach. I have a camera that can do nice slow motion video. I can post the results on youtube. I like seastead models.May 27, 2012 at 11:07 am #20575
If anyone builds any models and tests them in waves I would like to recommend a convention of posting video to youtube with “seastead experiment” as part of the tittle. This is what I have done and if others do this then it will be easy to find the video.
So a search like the one below will find what has really been built and tested in waves:

The map currently has me out in the ocean near Anguilla. But you can see the exact location of my dome here:

1-2 million is not too much for a lot of people – look at the going rates for all these simple boats:
yachtworld.com custom search – turns out $2M doesnt get you that far at the yacht dealership. but i believe it CAN get you far on a seastead!
That search limited boat length to 60 feet. If you take that limit off you can find all sorts of interesting things:
Even nice yachts:

Floating breakwater discussion is back again -
Let me post a few thesis for discussion:
1) Floating breakwaters in open ocean are possible.
2) Connections between floating breakwaters in open ocean are possible.
3) A breakwater lagoon is the most simple and cost effective way to allow a come together of ships, boats, houseboats, floating islands, in open sea.
Is any of those points still in discussion? – why?
Only question is what you mean by connections in #2. Clearly a rope or any kind of flexible connection could be made to work. If you tried to do a rigid connection then the forces on it and the breakwater could easily be enough to break something.
Note that there is a wiki page on breakwaters that people should feel free to update:
And I have a design idea with pictures and even a model tested in the ocean:August 24, 2010 at 10:37 pm #11194
Yes, I think starting small next to a Caribbean island makes sense. Here is one idea:June 24, 2010 at 10:26 am #10543xns wrote:
@ Vince, It’d take well in excess of 2 metric tons to break the section off, The hexatoon walls are twice as thick(10mm) as the HDPE barrels you used for your seastead model, I hope that gives you an idea of the mechanical stress you can place on them. That and they’ll mostly undergo compression and shear, not tension.
What is the advantage of having the inner part of that grove? What looks like a 2 layer telephone pole, why not stop at the first layer? Without the groves near the center the center and connection to the outer parts could be much stronger.June 23, 2010 at 10:21 am #10539xns wrote:
Hey guys, I’ve had some time to go over eveyone else’s posts since I was locked out of the forum the last few weeks, but on a side note, Hadean will hopefully have our hexatoons in the water by early August. Here’s some CAD renders.
It looks like the 6 parts have only a tinny attachment to the center part and could easily break off. Why is it designed to break so easy?June 12, 2010 at 10:27 pm #10458scebaran wrote:
Considering how easily plastic floats, how long it takes to break down, and how durable it can be, why havn’t I seen it considered in the Seasteading Beta Book (or elsewhere) as a serious contender for material?
I rode on a seastead I built with plastic floats:
I have talked about the BallHouse design being made with plastic:May 29, 2010 at 1:15 pm #10321
My personal favorite next step is:
But I have an idea similar to that but where each leg has a pontoon with a daggerboard and 2 electric motor on it attached to the leg in a flexible way. My CAD guy is back from school any day now and I will have him draw it up soon.
Now imagine that my family is motoring around the Caribbean or Atlantic on a nice new solar powered seastead. I make some videos about how well it works and how comfortable and safe it is. A lot like DashewOffshore does for their boats on youtube. I contact a few press people and someone does an article about this interesting new way to travel. Now if it really is as fantastic as I think it will be, then somebody will say, “Hey, I want one of those. How much is it?”. And if it really is sort of reasonably priced, I will be able to sell it. With the money from the first sale I can make a next one. Probably I fix a few little problems the last one had and my family starts traveling around in the new one. Rinse, repeat.
After there is a “Seastead Users Group” there will be some who decide to travel around the Atlantic, or some other route, together. This will be the first real seastead community.
Dude, the market decides. There are actually lots of designs linked to in the last 2 sections of the SFS page and many more not written up or linked yet. I think there is far more realistic work going on in the SFS area than in the “Floating City” area. Hard to really say who the market is going to pick at this point but I think it is a safe bet some SFS type thing gets commercial success before any floating city size thing even gets built. So if TSI is still trying to raise $200 mil to build some huge thing when I have steady sales and a community of SFS users traveling together, I win.

In these economic times, its impossible to “beat a boat” in terms of cost. There is no way that a SFS can be built cheaper than a good used boat (power or sail).
Let me try to clarify what I mean by “beat a boat”. How about this:
Some customers should feel a seastead “beats a boat” for their valuation of space, stability, safety, initial cost, operating cost, bragging rights, or whatever else. But really what it means is that in that customer’s subjective valuation it is somehow better than a boat.
Now it may well be that used boats are so cheap right now that it is an extra hard time to start selling seasteads. I still think it can be done.

So, what should the requirmenets for an SFS be?
The key idea is that a structure engineered for a family to live on the open ocean could be better optimized for this goal than anything else. It should “beat a boat” in terms of space, stability, and cost.
There are several different sub-catagories of SFS that have more specific requirements.April 15, 2010 at 12:17 am #9998sda1950 wrote:
Have you tried making a breakwater out of cylindars laying on their sides instead of the flat walls? They might work better as they provide a slopping surface for the wave.
You mean like this PVC model?

My point was that of an incremental approach to constructing seasteads is the only way to develop the knowledge and capability to build them. A construction company should start small, building floating individual houses and what not, then move on to larger and larger residential (apartment buildings) and commercial structures as the market develops for such. This provides a strategy for the incremental development of the technology and contruction techniques necessaru for the contruction of larger and larger stuctures on the ocean, while generating a cash stream while doing so.
I think my Floating Villa plan is the most incremental of the seastead approaches I have seen. What do you think?

I like the fact that Vincecate has actually put some cost figures down. However, these mean little because you haven’t offered a design.
I have published a number of designs on the wiki. My current favorite can be seen at:

The one thing I have difficulties with is your planned 1 to 2 knots (at sea we use knot/hour). You had better not be planning on navigating. If you come into a 5 knot head wind, you will be progressing at -3 or -4 knots along your course — that is you will be moving backwards. In order to navigate at a cruising speed of 2 knots, you had better design for a top speed of 20 knots.
You can buy an 8 foot propeller with a 3 or 6 hp electric motor on it. The low hp thrusters make it realistic to have the seastead run on solar power. These can give 530 lbs or 760 lbs of thrust. But they turn slowly and would only move you at slow speeds. If you had 4 of these then you would be able to make progress as long as the wind drag was less than 2000 lbs.
That said, I do expect to be heading downwind most of the time. And I will do a migration route with mostly good weather.
But I agree that you should have a design that can make headway even going into a 20 mph wind. That is almost a normal wind around where I live.
