What anime

No.10973027
can u guys help me remember the title of the anime...
it was a space opera kinda anime, but the space ships were like boats( and by that I mean they dont follow the usual spaceships in scifi)
its an old one because I remember seeing it as a kid and I think they can walk outside the ship too
oh and I think it was either chinese-esk or japanise-esk kinda setting
