Those Who Wanted to Found a Nation at Sea Lost to Those Who Just Wanted to Live on One
In spring 2019, the Thai navy sent three warships to demolish a small cabin floating at sea.
The cabin sat more than twenty kilometers off the coast of Phuket, anchored by a single steel pillar driven into the seabed, and it was home to an American couple. The charge announced was startling: endangering national sovereignty — under Thai law, punishable by life imprisonment or death. The couple happened to be away at the time, and went into exile. The cabin had floated for less than two months in total.
It was the first single-family home of the seasteading movement. The movement's complete record over the following seven years: three experimental structures, two government raids, one wanted couple, and a cruise ship bought and hastily resold.
This field is worth a full post-mortem. Not because utopias are entertaining, but because the way it failed is highly informative — over eighteen years, every dream of "founding a nation at sea" died, while every business that "just wanted to move a home onto the water" survived.
Terra Nullius Is Actually Every Nation's Backyard
The story's oldest survivor is still at sea. In 1967, the Briton Roy Bates occupied a WWII-era decommissioned sea fort — an anti-aircraft platform in the North Sea — and declared the Principality of Sealand. He died in 2012; his son succeeded him, and now the grandchildren run it day-to-day, operating a shellfish farming company alongside. Fifty-nine years: never demolished, never recognized by any state.
Another 1970s effort was more radical. Michael Oliver, a Las Vegas real-estate developer, shipped dredging vessels to Minerva Reef in the South Pacific, pumped coral sand into an artificial island, raised a flag, and declared a republic. The King of Tonga's warship arrived soon after, lowered the flag, and claimed the island. From flag-raising to flag-lowering: a few months.
These two episodes played out the entire script: occupy an unclaimed platform, and you can drift for a long time; fill in an unclaimed reef, and a sovereign state comes to collect immediately. "Unclaimed" waters were never a legal vacuum — just places whose turn to be governed hadn't come yet.
Silicon Valley Enters
In 2008, Patri Friedman — grandson of economist Milton Friedman — and engineer Wayne Gramlich founded the Seasteading Institute. Seed funding of $500,000 came from PayPal founder Peter Thiel. The office was borrowed, tucked in a corner of the data company Palantir.
Gramlich was the clearest thinker in the group. Around the same time, a group called the "Atlantis Project" started by drafting a constitution first. He recalled thinking: no technology yet, and you're writing a constitution? Absurd. He kept telling Friedman this wasn't a political problem but an engineering one — build a structure that can survive sea conditions first, then talk about what governance system to adopt.
The Thiels of the world were thinking about the other end: build a low-tax, lightly regulated new society at sea, injecting some competition into "government, this stagnating industry."
The institute's first major project landed in French Polynesia. The island nation faced a genuine existential crisis: rising sea levels could submerge it entirely by century's end. Its government initially saw a win-win — you practice floating-island technology, we learn how not to drown. A memorandum of understanding was signed in January 2017 for a seven-year plan.
On March 14, 2018, the new government announced its permanent withdrawal. A local official who took part in the negotiations later explained the cause of death bluntly: the demanded "tax exemptions, labor-law exemptions" were unworkable — "when you come from the Global South, these things have a whiff of neo-colonialism." His summary of the dream: they wanted a low-regulation floating island for tech billionaires, using our resources along the way.
Then came the Thai cabin, then Panama in 2020 — the same team's second base in the Bay of Panama, raided and demolished again, the couple escaping once more. That same year they changed tactics, buying a retired cruise ship, the *Satoshi*, to convert into floating residences. No insurer would cover it; eight months later it sold for below its purchase price to a new cruise operator. It was the largest asset the movement ever handled — and the fastest to fail.
The Reasons for Failure Aren't Mysterious
Three of them, each hard:
Legally, the sea has no gaps. The UN Convention on the Law of the Sea draws 200-nautical-mile exclusive economic zones where resources belong to the coastal state; vessels on the high seas fall under their flag state — whichever flag you fly, that nation's laws govern you. Water that "no one governs" does not exist in law. The Thai couple's cabin, twenty kilometers offshore, sat squarely inside the EEZ; even on the high seas, living aboard means picking a flag and bowing to it.
Politically, the more successful you are, the more dangerous you become. While nobody notices you, you can drift for years; once you make the news, sovereign states respond within weeks. The institute did its homework on "incremental diplomacy" with governments — a conclusion reality repeatedly refuted: negotiations collapse over exemption clauses, and raids come from the very host you thought you had.
Engineering-wise, the ocean is the most expensive construction site on Earth. Salt spray corrodes everything, wave forces are unforgiving, and maintenance costs run several times those of land-based buildings. Sealand survived fifty-nine years because it was a concrete platform built to military standards in the first place — that wasn't savings, that was an inheritance.
Who Survived
Across the same eighteen years, another group issued no manifestos at all.
A cruise ship called *The World*, launched in 2002, carries 165 owner-occupied residences — from studios at $600,000 to two-to-three-bedroom units at $2–3 million — continuously housing 150–200 residents under a Bahamian flag, sailing the globe. Twenty-three years: never raided, never wanted. Its entire secret: it never claims to be a nation — just a cruise ship flying the Bahamian flag with condos aboard.
The Thai losers' company, Ocean Builders, is still alive. The strategy changed: no more hunting for sovereign gaps — it legally registered and pays taxes in Panama, and turned the product into the SeaPod, a one-unit floating home priced from $300,000 to $1.5 million. New sites are chosen specifically in equatorial waters — hurricanes cannot cross the equator due to the Coriolis effect, so that belt is naturally typhoon-free. The CEO lives in the demo unit himself, and the company blog was still updating as of December 2025.
On the other side of the French Polynesian negotiating table, former official Marc Collins Chen went on to found Oceanix, repackaging the same floating-module technology with a new pitch: not selling to people fleeing nations, but selling to nations about to be swallowed by the sea. In April 2022, UN-Habitat endorsed their floating-city prototype for Busan — a planned 12,000 residents, originally slated for construction between 2025 and 2028. As of 2026, Busan residents are asking each other on forums: any news on this project? The official site hasn't been updated in over a year. The rebranded version never broke ground either — but it won something the original never did: the UN's nod.
Crypto came too. A private island in Vanuatu was renamed Satoshi Island, selling "citizen NFTs" to tens of thousands of buyers. In July 2025, the island announced: all digital-asset transactions suspended.
And one line of business never talks about freedom — and lives the most solidly: Norwegian fishermen. Salmon farming moved offshore: Ocean Farm 1, a semi-submersible steel offshore farm with a net capacity of 1.5 million fish, has been operating since its completion, weathering fish escapes and storms, patched and repaired, still farming. Demand for floating structures is real — the buyers just were never utopians.
Eighteen Years On
$500,000 in seed funding, three government raids, one wanted couple, one fire-sale cruise ship. On the other side: a cruise ship launched in 2002 carrying 165 households quietly circumnavigating the globe for twenty-three years, and three generations of a family building a shellfish business atop a North Sea gun platform.
Those who wanted nation-building all failed; those who wanted property all survived. The difference isn't money — Thiel's $500,000 wasn't small in 2008 — it's a question: do you want freedom on the sea, or a house on the sea. The former requires every other nation's consent; the latter requires only one nation's nod. In eighteen years, not one person built a nation at sea — but plenty have lived on it for twenty-three years and counting.
