A quarter of the 200 participants taking to the water are international paddlers and Spencer expects the event to attract global scrutiny.
"We have our younger boys and girls getting ready for the Rio Olympics, a large international World Series contingent and it is the New Zealand National Ocean Racing Championships, so all eyes are on us as we get ready for the World Masters Games next year."
Regulations require four course options are available to be run on either of two days to ensure the best possible conditions: it is likely most racing action will take place on Sunday.
As the weather forecast began to shape up, Spencer - a local and avid paddler - could barely contain his excitement.
"Having lived on Waiheke for 15 years, I just want to share the joy that is paddling into Auckland in a stomping northeasterly. The 'Waihetian Windrunner' is a favourite course for locals in the right conditions."
