Wreckage assumed to be from missing man Tony Higgins’ boat ‘Margrel’ has been located south-east of the Murray Mouth.
SAPOL officers located what is believed to be the bow of the boat, along with other debris just after 1pm today.
Debris along with other items thought to be from the wreckage have been recovered and will now be examined by police.
Despite the discovery, the missing 57-year-old is still yet-to-be-found.
The find comes following the news that the search for the missing man had been called off pending any further sightings or information.
On Wednesday, a bag containing personal items, including a wallet and keys thought to belong to Mr Higgins were discovered on Goolwa Beach.
He and Derek Robinson were the subjects of a major missing persons search earlier this month when they went missing on the same vessel south of Port Lincoln.
The ensuing hunt for the pair was the most wide-reaching marine search ever conducted in South Australia.
Higgins and Robinson were later located with Police towing the Margrel back to shore.
Despite the search efforts, Mr Higgins insisted that he and Mr Robinson were not lost and did not ask for a search to be conducted.
Anyone who spots debris along the coastline is being asked to contact SAPOL on 131 444.
