Mr Winyard said an attempt to pull the yacht into deeper waters failed later that day.
Mr Winyard said Coastguard was responsible for saving lives and since the yacht's owner was fine, he would now have to make arrangements to move his yacht. The yacht was still at the beach at edition time yesterday.
Ruakaka resident and experienced ocean sailor Margaret Hicks saw the yacht run aground and described the incident as a "monumental cock-up".
"I saw to my horror the yacht coming too close to shore and I said 'Oh my God, it's going to go aground' and it did.
"Then I saw a crew member trying to row to shore in a dinghy. He should have never come close to shore and should have put out the anchor in deep water," she said.
A fisherman unsuccessfully tried to help the owner start the motor.
"It's very frustrating because no one was able to do the right thing. If people knew what to do when the yacht first touched the bottom, the boat could have been out around 9pm last night [Saturday]," she said.
Ruakaka photographer Dan Sloane saw a Coastguard vessel arrive after 8pm on Saturday and try unsuccessfully to pull the vessel into deeper water.
