Heading into Friday's final two races Pascoe was locked for first place with Canadian Bruce Millar, the duo sat on 16 points.
But Pascoe didn't panic, collecting victories in the final races of the regatta to take sole lead at the top of the leaderboard and finish top of the podium.
Pascoe was in fine form across the pond, finishing no worse than second in the final six races of the event, with Canadian Allan Liebel taking silver ahead of compatriot Millar.
There was also plenty to celebrate for Nick Dempsey in the men's RS:X event as the London 2012 runner-up finished with silver.
The 32-year-old had to settle for second best behind Spain's Ivan Pastor but did get one over London Olympic champion Dorian Van Rijssbelberghe as the Dutchman finished third.
Fellow Brit Elliot Carney made the final, finishing sixth, the same position Izzy Hamilton finished in the women's RS:X event.
But there was disappointment for Beijing Olympic bronze medallist Bryony Shaw after she finished agonisingly short of the podium in fourth.
Meanwhile, Alex Mills Barton will be in action in Saturday's three Laser medal races after finishes of fourth and 12th were could enough to keep him in the top ten.
This will be Mills Barton's first World Cup medal race appearance, although compatriots Jack Wetherell and Matt Reid's Miami adventures ended as they finished 25th and 27th respectively.
