Windsurfing club spokesman Peter McInally reminded those gathered under their umbrellas of how special Jardines Beach and the lake were to Ms Green, who died nearby after she fell from her board in extreme conditions on the lake in last February.
Standing among rose petals scattered on the ground, Mr McInally recalled the windy conditions on the day she died and said they were very similar to those also experienced on Monday, February 16 last week, a year exactly to the day of the accident.
The coroner's report into her death released in Queenstown last September said evidence suggested she was struck by a hard object, her board, mast or boom, causing "superficial injuries" to her head, the impact causing her to lose consciousness.
While she was out on the lake alone, Ms Green had taken all the right safety precautions of wearing a lifejacket and helmet, points noted by the coroner, which Mr McInally said was helpful to the windsurfing fraternity because, had she not taken such precautions, more regulations might have been imposed on the sport.
"While Jude was not a public person, perhaps this was her legacy to us all," Mr McInally said.
Unveiling the plaque and large memorial schist stone (gathered from the Dart River by club members) was an important part of the grieving process for all, Mr McInally said.
Ms Green's brother-in-law, Jay Cassells, also paid tribute to Ms Green and thanked the windsurfing club members for being such good friends and being so supportive to her family.
In a moment of lightheartedness, Mr Cassells also added Ms Green would have appreciated that "schist happens", and that the stone memorial on Jardines Beach, in a place Ms Green loved, was a fitting memorial to her.
The downwinder windsurfers and kiteboarders races planned to follow the memorial service were postponed until next weekend.
