A bone belonging to a man involved in a fatal boating trip with friends off Tasmania's northwest seven months ago has been found by a recreational diver.
Thomas Courto, Isaiah Dixon and Bree-Anna Thomas set off from Wynyard for a day trip on October 18.
The bodies of Mr Dixon and Ms Thomas were discovered several days later after a large-scale air and sea search involving members of the local community, but no trace of Mr Courto was found.
