Wong Chi-wah, a boat operator in Aberdeen Harbour, said that in the glory days of the Jumbo Kingdom in the 1990s, flocks of Japanese tourists would visit the restaurants.
"The streets were full of parked vehicles as visitors arrived in big groups," he said.
Encore Sin, 71, said Hong Kong was losing something unique.
"If the restaurant leaves today, there is definitely a sense of loss, not just for people who live around this area but for the whole of Hong Kong," said Sin.
"Over the past few decades, I've been to many places around the world to take photographs, but where else in the world are there such floating restaurants? I don't think there are any left."
