Please help me

I'm trying to remember the name of a cartoon around the 80s-90s it had a woman who was the baddy on a boat that I think she lived on. There was a big wheel type thing and I think a fairground. I can't remember if they liveed under water or could swim under water but I seem to remember this. Please help I'm going insane trying to work it oue arahhhhh

I don't remember a wheel. But when you said wheel I though of this one. Weird.
