Sometimes people from the Navy and from oil rigs in the North Sea say Seasteaders are naïve. But environments on the sea are as diverse as environments on land. Just as the continents feature the Himalayas and the Sahara, the oceans feature the North Sea and the tropics.
When a wave hits an iceberg, seals sleeping on it rarely feel it move. Floating oil rigs operate on the same principle. The submerged pontoons that support these floating societies are so heavy, workers often play ping pong on the high seas.
Tsunamis are luckily harmless on the deep sea. They’re only destructive when they reach land.
