I think the starward and southward were closer. Skyward was more diff than those 2.
The sunward 2 was actually the Cunard Adventurer and had stabilizers and such that skyward didn't.
Somewhere, I used to have a postcard of the Sunward (1) pulling into Nassau.
I remember the carnivale (Carnival) and Carla c (costa) roaming the Caribbean. NCL was modern compared to them. Then Norwegian had the song of Norway.
