"We rang that on four occasions but just no response," Mr Whitham said.
He is hoping the owner of the boat will remove it within 14 days otherwise it will fall on the council to do so.
"The fact is that it's sticking out on to council land," he said.
"I would deem it as abandoned at this stage, the same as an abandoned car, in which case we would end up moving it.
"It's not the property owner's [responsibility] because he doesn't want it there, it's not his boat. He shouldn't have to put his hand in his pocket for anything.
"All we want is it moved. The reality is there's a cost to council if it's not moved. We've had a look at it and it's going to be quite expensive."
The yacht is in poor condition and has as hole in the bottom but Mr Whitham said it would probably be repairable for someone with the skills to do so.
