Mr Malcolm said he and his son had spent plenty of time on the Rotorua lakes when Ben was growing up although more hours were spent on power boats.
Mr Malcolm said his son was discovered by Team New Zealand while working at Salthouse Boat Builders. They saw his work ethic.
"He has the ability to work day after day after day with very few hours' sleep. That's the ethic they obviously saw."
"It's nothing for Ben to do 20-hour days ... "
Mr Malcolm said a highlight had been when Ben had taken him to show him the boat in Auckland.
"It was a bit humbling what Grant Dalton had to say about him."
Rotorua artist Warren Houston, who was commissioned to airbrush the New Zealand flag and chrome-look detail on both hulls of Team New Zealand's catamaran, said it was a nerve-wracking experience.
"We started with such a burst it gave all of us so much confidence. But with the huge backing Oracle has got, I did think they would catch us up.
"It got more and more nerve wracking over the week ..."
Mr Houston said he was incredibly proud to see his artwork on the boat and felt like he had been part of the team since the beginning.
"Even though I haven't been over there I feel, like a lot of people, a part of the team, it's an awesome result," he said.
