"But there has been some really good things come out of this week. I'll just have to take all of the learnings out of this medal race."
"I felt a little bit sticky upwind, a little bit slow at times. In saying that it was quite patchy and quite light so it's hard to know if it was speed or where you are on the race course.
"It was a really difficult one, it wasn't straight forward. ."
Not intent at losing sight of a Finn Gold Class podium finish in the future, Murdoch said.
"I've just got to keep pushing hard from here".
"It's good to post a good result at this stage of the cycle.
"There is still plenty of time for me to make some improvements and cut down that gap that Giles [Scott] has got on us all at the moment. He's sailed really well this regatta."
Giles Scott was awarded the gold medal and closed the regatta 45 points ahead of Jonathan Lobert of France, who won silver.
