Used to work on one.
The ships were originally registered in england, or that was their home port. My understanding is it was a tax thing. Eventually, they moved their ships to the USA or most of their ports were miami or new york depending on the season. They did originally travel around england, I believe, but moved operations to the US. There were four ships...island breeze...sea breeze...ocean breeze and one other breeze that escapes me. I was on the island breeze, which is now at the bottom of the ocean. No proof, but it was pretty sketchy and it was probably insurance related. No one but a skeleton crew were on board and everyone was rescued. That was around 1999. Most of the remaining ships were to be purchased by a larger line, but I never heard if it happened (didn't follow the story).
