"It's good to team up with mates from Team New Zealand and also take on the other weekend warriors," van Velthooven said. "I consider myself an enthusiastic weekend warrior looking to learn as much as he can.
"As soon as I came back [from the America's Cup], I wanted to find out about the grassroots of the sport. I signed up to as many crews as I could – whoever wanted to take me.
"I've done a lot of Young 88 and TP52 sailing. Everyone was happy to help because they needed people to sail the boats."
As many as seven TP52s have entered in the A division for Bay Week and nine will line up in the B division, which promises to be one of the most competitive among the 13 divisions in the three-day regatta,
Another contest that will pique interest will be the battle of the trimarans between Frank Racing and Beau Geste, who competed for line honours in last year's Coastal Classic.
Van Velthooven was also aboard Kia Kaha for the Coastal Classic, a race from Auckland to the Bay of Islands, describing it as "one of the cooler things I have done on a boat".
His interest in sailing existed long before competing in the America's Cup but he never thought it was something that was realistic.
"Being in the America's Cup made me realise that sailing is really accessible to anyone in Auckland and New Zealand," he said. "It has been good fun learning.
"I want to learn as much as I can and get as fit and strong as I can. This is my way of becoming a better sailor and getting experience on the handles for the defence [of the America's Cup] in Auckland.
It's killing two birds with one stone. I really enjoy racing in any sport so it's good to get out thereand compete."
More than 100 boats are expected to line up when racing at the Bay of Islands Sailing Week gets underway on Wednesday.
