Western Challenge sailors on Lake Christina may have noticed the drone buzzing around over the weekend. Montana photographer Sean Heavey made the trip to the Challenge and has shared his photos. He sends his apologies for not getting everyone’s pictures because he spent a lot of time practicing flying the new drones and figuring out to cover the action with them. See the photos here.

Cancellation of the 2022 North American Championships: U.S. Nationals Called ON

The IDNIYRA Governing Committee earlier announced plans to decide by November 22th the status of the 2022 North American championship. The Governing Committee has agreed that continuing changes, challenges, and uncertainties relating to the pandemic make it apparent that holding the regatta in 2022 is not in the best interest of our class members. Therefore the 2022 North American championship is canceled.

However, based upon the success of last year’s non-ranking U.S. Nationals Championship, IDNIYRA Governing Committee has decided to endeavor to hold another non-ranking American Championship in the same timeframe. Central Rear Commodore Rob Holman will soon release Notice of Race for the U.S. Nationals.

DN in Sailing Museum

Visit the Sailing Museum

The DN remains the world’s most popular iceboat for many reasons. It’s usually someone’s first ride, home buildable, easy to transport and set up, and pure fun to sail. The DN is also the perfect size for a permanent exhibit in the National Sailing Hall of Fame’s new museum in Newport, Rhode Island.

The DN’s natural wood hull, plank, and runners will stand out among the other five soft-water boats that will permanently hang from the former armory’s impressive wood ceiling in the interactive exhibition hall.

Home built by Doug Kolner (Four Lakes Ice Yacht Club) in Monona, Wisconsin, the boat reflects the DN’s humble beginnings at the Detroit News hobby shop in the 1930s and its evolvement into a modern racing machine. Doug built the boat using standard plans and it is most representative of the type of DN you’ll see at North American regattas. Typical of modern DN racers, the hull was built using Gougeon brothers epoxy, Harken brothers blocks, and Sarns hardware.

The DN class is honored to symbolize the spirit of American ice yachting in the new Sailing Museum.

2022 North American Championship Update

COVID 19 continues to affect our everyday activities of life, whether home, work, or leisure. Border crossings between Canada and U.S. remain challenging and in flux. It may continue to affect our coming hard water season, but we have plans in place and a decision-making schedule.

The Governing Committee will hold a conference call on November 22, 2021, to decide whether the North American Championship (23 – 29 January 2022) can be held. The decision will be published immediately after the meeting. This allows two months lead time for the regatta, both for the organizers and for those competitors who need to plan international travel.

Suppose the Governing Committee decides that the North American Championship cannot be held. In that case, we will plan to run another US-based Championship during the same period as the scheduled North American Championship. Canadian members might decide to run a Canadian regatta in the same period. A U.S. Championship and a Canadian Championship would be non-ranking events.

Some factors in the decision-making have to do with the risk of a COVID positive test and quarantine requirements before reentering Canada or the United States. Canadians still face some severe logistical and expense problems attending regattas.

If the conditions don’t improve, the North American Championship could not be held. It would fail the most basic measure of fairness to have a  championship when it’s too great a burden for international competitors.

Please feel free to engage the Governing Committee if you have further questions. We are committed to offer racing this winter subject to constraints that might be imposed by COVID 19.
