Kirkcudbright Sheriff Court will hear the 42-year-old give evidence to an inquest into the sinking and the subsequent death of the seven fishermen on board.
The boat sank 11 miles off the coast of Isle of Man in January 2000 in rough seas.
Mr Gidney, who has a home in Gatehouse, angered Manx authorities by failing to turn up at a coroner's inquest on the island.
Coroner Michael Moyle said Mr Gidney faced being called a "coward" and "hypocrite" by the families of the seven victims after his non-appearance, and a request to the Court of Session in Edinburgh was granted in February which will see Mr Gidney's evidence obtained on commission from Kirkcudbright courtroom.
Mr Gidney was cleared of manslaughter after a five-week trial in May 2006.
Craig Mills (29), his brother Robin (33) and their 18-year-old cousin David died on the boat, along with 26-year-old Martin Milligan, David Lyons (17), John Murphy (22) and 17-year-old Wesley Jolly.
Their bodies were discovered on board the vessel, 35 metres underwater.
The Solway Harvester was raised from the seabed in June 2000 at a cost of £1million and currently sits in Douglas Harbour, Isle of Man.
The hearing at Kirkcudbright will be the latest in a long line of attempts to hear Mr Gidney's evidence since his trial.
