I didn't include the port number, so perhaps that is what happened. Though I'm pretty sure I saw Havoc there.
I didn't actually get to an island, I followed the coast until I no longer saw signs of civilisation. The last structure I saw was a well-lit house under a crude American flag.
I also saw a giant stone structure, like an upside-down "L" one block thick, floating in the sky over the ocean. Beneath it was am underwater pillar that stopped just under the surface, one of four that marked the corners of a square. Inside the square the sea level was one block lower than the rest of the ocean, so water kept pouring in, though it never filled up. Very strange. I thought my boat might have gotten stuck in it when I had to sail uphill.
