Endel Vooremaa 06.05.1930 – 25.07.2022

A true icon of international ice sailing, Endel Vooremaa, passed away today in Estonia. Ron Sherry US44 shared his thoughts about the man from whom he “learned more than anyone else” about building iceboats. The North American DN community sends its deepest condolences to Endel’s son Vaiko, grandson Argo, and family.

Endel was an innovator. He had one of the earliest super bendy wooden masts and designed the crown at the hull’s bottom. He showed me how to build runner planks, telling me to follow the grain pattern to “put the tree back together.”

A day before the 2002 World Championship in Haapsalu, Estonia, my DN was damaged when it blew off the car as I unloaded it. Michał Burczyński P114 gave me Endel’s phone number, and I called him. Endel immediately recognized my voice and invited me to bring the damaged boat to his shop, where Endel repaired the deck and steering post. I went on to win the Worlds that year, which wouldn’t have been possible without Endel and his son, Vaiko’s help.

Endel was the regatta chief judge in the famous video, The Gods of Speed, about the 2003 European Championship.

1966 DN North American Championship

Mike O’Brien US3456 recently rescued a stack of vintage sailing magazines headed for the recycling bin. Mike, a three-time DN World champion, and one-time North American champion, shared a photo of an article from One Design about the 1966 DN North American championship. Gull Lake in Michigan hosted the regatta.

Gull Lake was also the site of the first DN World Championship in 1972. The DN class will observe the 50th anniversary of that first World Championship on January 21-28, 2023, hosted by the Western Region. It’s time to start thinking about sharpening your runners for the 2023 season!.

Mike O’Brien Runner Tracks Interview

“I’d Like To Get In To Ice Sailing”

Michael Dunston and FIER on Canyon Ferry in Montana, the first DN to be registered with the Sydney (Australia) Royal Yacht Squadron. 

In November 2021, Australian sailor Michael Dunston emailed me about continuing his ice sailing journey, which had begun in the Netherlands in the previous winter.

I’m from Sydney, Australia. I have grown up sailing all my life. I tried ice sailing on a DN for the first and only time last winter opportunistically in the Netherlands, and I loved it. This year I moved with my family to Bozeman, MT, which is where my wife grew up. I would like to find a way to do more ice sailing!

If there was an inexpensive, entry-level ice boat (a DN, or similar), then I would be interested to buy. Naturally, it would also be great to connect with some like-minded folks. Is there a club or a group that sail on Canyon Ferry MT that I could connect with?
Michael Dunstan

Michael is one lucky sailor, having been in the Netherlands 2021, the birthplace of our sport, for their few days of ice sailing, then landing at Canyon Ferry, a place of legendary North American ice.

I forwarded Michael’s email to Canyon Ferry iceboaters Dale Livesey and Dave Gluek, who welcomed him into the community and pushed him off the line.

I wanted to update you on Michael Dunstan, the Australian sailor. He’s an awesome guy and a good addition to our fleet. He purchased Dale Livezey’s DN and is a quick learner. He has been fun to sail with. Mike’s Dad is visiting Mike this week, and we sailed a Nite in big wind the other day. Both of them are accomplished sailors! Thank you for introducing us.
Dave Gluek US5526

Michael’s mother, Judy, wrote an article about their visit to Big Sky & Ice country for their yacht club’s newsletter, the historic Royal Sydney Yacht Squadron. In addition to receiving a British empire Royal charter in 1862 and challenging for the America’s Cup in 1962, the RSYS has added Michael’s DN to their Squadron Yacht register in 2022.
