cartoon aired in the 80's on the ABC, 3 people lived on a boat and little people lived on the island?

What I can remember was the 3 people on the boat where, an old guy, a youngish bloke in light blue overalls who was a bit of a push over, and a tall skinny woman who wore a red suit and from what i remember her name was Miss Emma,. There boat wasn't exactly the eco friendly, it had like a pool of oil and rubbish i think all around it..

the little people that where on the island were like little midgets (trolls) one had blue hair and i think his name was cool, who also wore sunglasses, a princess with red hair, an old doctor type guy with the white beard glasses and white top hat.

I remember this being aired in australia in the 80's but I cant recall the name of the show, if anyone can remember this please let me know cause i would like to try and watch it online if i can.

Thanks...
