Staff on a Coastguard vessel were on the scene within 20 minutes. They assessed the men - one aged in his 40s and the other in his 50s - and dropped them back at Half Moon Bay, from where they had launched.
Ms Smith said the service wanted everyone to have a happy public holiday out on the water. Traditionally one of busiest days of the year on the Waitemata, it will draw hundreds of boats either to compete in events or as spectator craft, making it imperative that people check the marine forecast this morning, be courteous and make sure they had two forms of waterproof communications such as a VHF marine radio and a cellphone in a plastic bag.
Today also marks a year since Jill Hetherington was seriously injured when the classic boat she was on, the 10.4m Gypsy, split in half after another yacht, the Antaeus - skippered by businessman Charles St Clair Brown - hit it.
Then aged 60, she suffered a fractured pelvis, nerve damage and deep bruising.
Her partner, John Pryor, who was also on board, told the Herald Ms Hetherington would be competing in the regatta in a tugboat race.
She was unavailable for comment but Mr Pryor, who has been critical that Mr St Clair Brown received a $200 harbourmaster fine and nothing else, said the amount of traffic in the harbour today should make people wary.
