John Weller has not missed an Auckland Boat Show for 51 years.
The 81-year-old was this week at the show, which is marking its 60th year at Auckland's ASB Showgrounds.
He said boating and water had been his life and even his family had "had to belong to boating, to belong to me", he joked.
Mr Weller has owned about six different types of boats over the years, but after selling his last water-ski boat 10 years ago, decided to try something different.
"It was a bit sad that I had no boats in the water ... so I went and bought myself a jet ski."
