A stakes-winner last season for the Hayes Dabernig team at Lindsay Park, Fastnet Tempest struck his best form when powering to a dominant length and three-quarter win in the 1600 metre feature.
Previously trained in the UK by William Haggas, Fastnet Tempest has the overall record of eight wins and 10 placings from 32 starts with prizemoney in excess of $660,000.
He is the best of seven winners from Dame Blanche and is a half-brother to the dam of Group III winner Sweety Dream.
Fastnet Rock added a 146th stakes-winner to his tally when promising mare Hinerangi took out the Listed James Bull Rangitikei Gold Cup (1600m) for the powerful stable of Murray Baker and Andrew Forsman.

Having his first ride aboard Hinerangi, winning rider Robbie Hannam was delighted with the result as he joked about the imposing physical presence of his mount.
"She's a monster isn't she," he said.
"She races on pace and grinds really good and she only had 53kg on her back today.
"What I didn't want to do was sit and sprint as I wanted to make it more of a staying mile.
"That's what happened as there was only two of us in it at the end and she just out-toughed the other horse."
Christopher Grace was also full of smiles with the victory in a major race at his home track.
"It's a wonderful thrill to win a race on your home track," he said
"The mare will be going out (for a spell) now, she's got a bit of black-type and that's what we want."
Hinerangi is the first winner for stakes-winner Hinemoa.
Fastnet Rock stands at Coolmore this spring at a fee of $165,000.
