NSW Maritime executive director Mark Hutchings said Transport for NSW would be seeking about $20,000 from the owner to cover the cost of salvaging the derelict 11-metre ferro-cement sailing boat.

On Thursday, August 15 local crews from Birdon Contracting used a crane to transport the dilapidated vessel from the emergency mooring on Laurie Street, Laurieton to the tip.

Mr Hutchings said it is the responsibility of owners to dispose of their boats properly and to respect the various forms of moorings available.

"These include private moorings which are yellow, commercial moorings which are orange and pink courtesy moorings, which are for recreational boaters to use for up to 24 hours only," he said.

"Emergency moorings are blue and are for exclusive use by NSW Maritime, Marine Rescue and NSW Police to store vessels short term and during an emergency."

Mr Hutchings said a poorly maintained vessel can sink, polluting the waterways and the environment. He said it can also be a hazard to navigation.

NSW Maritime is working with boat owners to ensure waterways across NSW are safe. Crews are carrying out regular checks to ensure private moorings are compliant.

"A boat owner whose boat breaks away can be responsible and not covered by insurance, if it causes damage to other moored vessels, maritime infrastructure, the environment or other boating users," Mr Hutchings said.

"To ensure the mooring is installed correctly, boat owners should engage an experienced mooring contractor for the annual service.

"This is a requirement as part of a mooring agreement"
