Together with riding partner Callum Farnell of Russell, Mr Whale raised just over $16,000.
This year, the duo's efforts have already hit $12,720 so Mr Whale expected to beat last year's total.
"He and I fundraise together because within the group there is a competition to earn the most money. Last year we won it and this year we're going all out to win it again." Mr Whale said the event had almost doubled in size since last year's inaugural race.
"Last year there was about 15 skiers, this year there's 24. We raised between $60,000 to $70,000, so this year there's going to be a lot more than that purely because of numbers."
Mr Whale said melanoma was an important cause to fundraise for, particularly for jet skiers who were exposed to the sun for long periods. His father-in-law had also had a brush with the disease.
