The Cruise Ship Seastead is one of the types of Seastead. The key idea is that by purchasing an existing ship we could eliminates R&D costs and the uncertainty about the costs and capabilities of the structure. This could make getting started easier.
Arguments In Favor
- See also Patri's ShipStead project page.
- Ships are known to work fairly well on the ocean. They're somewhat survivable in large storms. They're relatively mobile, and that mobility can help avoid storms, visit more ports / countries, etc.
- There are very efficient shipyards with lots of robots building cruise ships for reasonable prices.
- You can buy used cruise ships for reasonable amounts of money.
- These could then be sold off as condos at reasonable prices.
- Many seastead ventures like a Medical Business do not need a custom designed structure.
- This could be a lower risk way to get an ocean safe seastead going.
- Jeff Chan prefers the term "CondoStead" since a condo/timeshare is a familiar concept, easier to sell and explain, etc.
- Essentially this idea is like Residensea / The World, but at a lower cost and with hopefully better economic structures.
- A ship is much easier to pull into port, which is good for touring, repairs, resupply, etc. And they can also loiter in the open ocean fairly well. A spar may have a draft too deep to pull into port, so it may need to stay in the open ocean. With a ship, you can choose whatever combination of touring ports and camping on the ocean that you like.
- Ships are not as radically different as a spar buoy, and possibly not as comfortable in large waves. Spars have much lower waterplane area than most ship types, though SWATH come close.
- Spars may be much better at staying on the open ocean than a ship. For example ships generally need to be in motion to be stable. Spars are designed to be particularly stable when not moving through the water.
- Ships may cost more to build and operate than a series-production spar structure.
- It's not easy to raft or join ships together to form larger communities, though the same could be said for spar structures (or any vessels on the ocean).
- A ship that stays in International waters is probably too boring to live on, but one that visits islands is probably no different than any other cruise ship.
