Video - Goodison closing in on Laser gold
Britain's Paul Goodison will take a commanding lead into Tuesday's Laser class Olympic medal race, following three strong performances on Monday.
The Sheffield-born 30-year-old won the day's opening race in Qingdao and added subsequent finishes of fourth and sixth, establishing an 18-point lead.
He would have to come last or sink in the finale, and Sweden's Rasmus Myrgren finish first, to be denied gold.
Britons are also well placed for medals in the men's RS:X and Star class.
Goodison was heartbroken to finish in fourth place in Athens, missing the podium by the smallest of margins.
I didn't start off that well, but I managed to come good in the end
"This means everything, to come back from all the heartache and prove to myself I can be number one," Goodison told BBC Sport ahead of his medal race.
"At the beginning of the week all the results were up and down, I didn't start off that well. But I managed to come good in the end."
Iain Percy and Andrew Simpson enjoyed a superb Monday in their Star boat, surging to second place overall with four races remaining.
Percy and Simpson led from start to finish in their final race of the day, to move within three points of class leaders Fredrik Loof and Andrew Ekstrom of Sweden.
Nick Dempsey similarly sits second in his RS:X windsurfing class, three points behind New Zealand's Tom Ashley, with nine races completed.
Dempsey posted strong finishes of fifth and third on Monday, following a disappointing 17th on Sunday.
Bryony Shaw also did her medal hopes the power of good in the women's RS:X, placing first and third in races eight and nine to move fourth overall, nine points off the lead.
Leigh McMillan and Will Howden placed 14th in Monday's first Tornado race, but will discard that result as their worst to date.
The pair subsequently posted two seventh-place finishes to leave themselves 12th overall, with four races to come.
Penny Clark had a day to forget in the Laser Radial class.
Clark finished Monday's three races in 18th, 23rd and 13th position respectively, leaving her in 10th place overall - just enough to qualify for Tuesday's medal race.
