On January 9, 2019 the world’s first seastead is now in the water off the coast of Phuket, Thailand built by the company Ocean.Builders. The single family seastead, named XLII (pronounced “ixly”), is a spar design seastead where a small fiberglass platform sits atop a large steel spar.

The steel spar is 20 meters long and 2 meters in diameter at 14mm thickness. The bottom is ballasted with concrete and sand. The spar can be filled with water to lower it during calm weather and it can be pumped out to bring the height up so that the platform is positioned high above the waves. The seastead is able to withstand 5 meter waves but will be sitting in the Andeman Sea where the average wave height is half a meter.
The platform is the living space, sitting several meters above the water. It is a six meter wide octagon shape with two floors. The bottom floor with a kitchen, bathroom, eating area and bedroom. The top floor is an open deck area covered by a solar panel frame which will create electricity for the seastead. The plan is to sell these seasteads at a price lower than the average single family home.
The spar was placed into the water last week and now with the platform in the water the full seastead is ready to be towed out 12 nautical miles to international waters and combined in its final sitting location among the islands of the tropical Thailand waters.
Ocean.Builders is a small group of entrepenurial engineers that are tired of talking about seasteading and are determined to make this thing happen.
More information is coming and can be watched here at ocean.builders as well as Youtube and seasteadtalk.org.
Exciting times for Seasteading!
Great work OB Team!!
Hello, we live in Venice island. We are interested to purchase a seastead.
We want to live in this place in our venetian lagoon.
Can we pay it with bitcoin?
Our current plan is focused on seasteads in international waters in Thailand so that we can mass produce for a single location to keep prices down and have a seasteading community in one place to grow.
The spar design is made for handling waves but needs fairly deep water. We could do a custom platform for your location but being in a lagoon it wouldn’t be a seastead, just a house boat. And the shipping costs would likely double or triple the price.
Thailand has many benefits for early seasteads including low prices, perfect sea conditions (low waves, no hurricanes/typhoons) and a country that thrives on tourism while leaving most businesses alone.
And of course we will be accepting bitcoin. Anything else will be more difficult.
Job well done Elwar!!! XLII is great! Go, Elwar go !
Congratulations!
Very interested in hearing more about this.
As a scuba instructor, blue water sailor, and designer/builder I would love to get involved.
Thank you,
Zack Smith
