Supermaxi Black Jack has claimed Sydney to Hobart line honours sailing into the Tasmania port in the early hours of Wednesday morning.
The Mark Bradford-skippered, Monaco-flagged yacht crossed the line after 2 days, 12 hours, and 37 minutes.
It was the slowest line honours time since 2004.
Co-owner Peter Harburg said it was a very emotional victory for him.
"For me it's the first time I've been involved in the winning team. Mark has done it before but it's very special.
"We came to win, we can win the race. So yeah, we gave it everything."
Skipper Mark Bradford spent a lot of the race below deck suffering from sea sickness.
"I just had internal problems, mostly my stomach was coming out of my mouth,"
"Maybe it's in my DNA. But yeah, certainly I'll put it down to the conditions today."
