From the Yearbook:

On February 21 and 22, 1953 the Detroit Ice Yacht Club sponsored a regatta to bring the DN skippers together to help form an association. A meeting of the skippers was held at this regatta and two representatives from each club present were chosen to outline a constitution for the association. North Star Sail Club was represented by John Liston and Fred Kagel; Anchor Bay Ice Yacht Club by Tom King and A. J. Walker; Detroit Ice Yacht Club by William Sarns and Clifford Cartwright. The representatives met at the home of the Cartwrights the following Sunday afternoon and briefly outlined a constitution. William Sarns was elected to serve as temporary secretary and to compose the constitution. The secretary prepared a constitution and sent out copies to the representatives in the following fall. They were returned to the secretary along with desired changes. The changes that the majority wanted were incorporated and 200 copies were printed. A copy was sent out to each individual who attended the first regatta and others who were interested. On January 17, 1954 the Northwestern Ice Yachting Association passed a resolution that they would accept the DN Association’s specifications for their DN races which are now included in their annual regatta.

On January 7, 1954 the North Star Sail Club offered to be host for the annual regatta. There were no other offers so theirs was accepted. Sixty-two programs were sent out on February 1 for the regatta scheduled for February 20 and 21. On February 19 the regatta was transferred to Cass Lake because of poor ice at the North Star Club House on Lake St. Clair. The
first five DN’s in this regatta were: (1) Jack Moran, (2) Skip Boston, (3) Paul Eggert, (4) Bill Sporer, and (5) Bill Sarns.

Paul Chamberland Opens NA DN Season in Alberta, Canada

Paul Chamberland KC5700 kickstarted the North American ice sailing season on November 21, 2023, near his hometown on Owlseye Lake, Alberta, Canada. Getting his DNs onto the ice required some elbow grease, but the effort was undoubtedly worthwhile. On his way back to the east coast, Paul is planning on attending the first fun-regatta of the season, the Western Challenge, in Minnesota, December 1 – 3, 2023. Keep an eye on the Minnesota Ice Sailing Facebook page for the latest information.

It took all morning to carry both boats from the road to the lake through the woods. Got a couple of hours of sailing in. The wind was very light at that point which was good as I was exhausted from getting the boats to the lake. Amazingly only 12 minutes from where I grew up! Because there is no access I had never been to it before this week. It’s mostly 3.5’ deep and 5.5’ at the deepest

The Flag is UP Early in Sweden

Stefan Bokfors S107 on Lake Ansjön in Sweden.

While we here in North America are stowing away sailboats for the season, in Sweden, the DNs are hitting the ice. October 30, 2023, kicked off the 2023-2024 season for class members Dideric Van Riemsdijk (S867) and Stefan Bokfors (S107). They found ice at Ansjön, a spectacular location situated 6 hours north of Stockholm. This year, October 30 marked the earliest start for Dideric and Stefan, giving them ample time on the ice for training before the Week 46 Regatta in Finland, which takes place November 17 – 19, 2023.

Important nutrition at the training table.

Bob Dill US3904: Eight Bells

Read Bob’s obituary here.

The DN Community mourns with the family and friends of Bob Dill US3904, who passed away on October 28, 2023.

Bob served as IDNIYRA Class Secretary from 1988-1991 and Class Treasurer from 1988-1989. He has been nominated to the U.S. Sailing Hall of Fame.

Via Bob Schumacher, Bob’s DN road-warrior and land-yacht-speed-record colleague:

With much sadness I have to report that Bob Dill passed last night after a battle with Alzheimer’s disease. I am at a loss for words but Don Brush said it well.
‘A sad struggle for a unique person. He is, I am sure, in a better place now. He would not have wanted to be the person he had become. We all were better for knowing Bob. I don’t think I ever met a more inquisitive person with a passion for details. His passion for documentation assures his legacy will live on! It was an honor to know and have him as a friend.’ Don Brush
Bob Schumacher

Bob used his sharp engineering mind to quantify wind, ice, land, and speed in several articles. One of his most famous projects was designing and building the land sailing yacht IRON DUCK with his friend, Bob Schumacher. Together, they set a land-speed record.

Bob Dill has left a legacy of articles that have left a last impact on ice and land sailing. Below are some links to a selection of them and other articles about Bob.
