DIVERS completed an underwater investigation in the Calliope River to determine how best to raise the submerged yacht Torres Herald on Friday.
The divers were planning to use inflatable devices to carefully raise the 85-year-old vessel over the weekend.
Victoria's Galloway family, who purchased the yacht a month ago and had not set foot on it, when it sank last weekend.
The family has vowed to restore it.
Space Marine's Danny Aeschlimann has been diving and rescuing boats in the Gladstone region for 42 years.
"I knew the boat when it was going down," he told The Observer. "Somebody rang me.
"But I had a lot of work and wasn't chasing anything.
Mr Aeschlimann is currently recovering three other vessels from their watery graves one of which is nearly 30 metres in the drink.
"This is not fully submerged, so it won't be so hard," he said.
The Galloways will travel to Gladstone to oversee its restoration.
