“How Would You Know?”

Paul Krueger M165, Ken Whitehorse M197, and Bill Mattison M143. Class A Skeeters, c. 1980s
The subject of sailing on Lake Koshkonong, about 30 minutes south of Madison, came up recently on the 4LIYC Facebook page. Koshkonong looks inviting as you drive past. It was a reasonable question to ask, why not Koshkonong?
Well, 4LIYC members and other ice sailors just “know,” and here’s how:
C Skeeter sailor Pat Heppert remarked, ” When I lived in WI, I spent years driving by and checking it. So tempting many times when it looked like glass ‘from the road.’ But whenever you walk it, all sorts of WTF problems show up. I finally gave up and concluded Koshkonong is just not meant for iceboats. The root source of the problem is the highly variable water level, which causes all the subsequent problems.”
The definitive proof came from a Mattison-Krueger-Whitehorse adventure on Koshkonong back in the 1980s.
Ken Whitehorse:
Ken, Bill, and PK
There was a big setup area. PK and I went tearing out to the lake. We saw spring bubbles to port and starboard. It was a gauntlet of spring water bubble-ups, like aerators. There were so many we could only turn around once we found a big area. As we sailed back to shore, we couldn’t follow our old runner tracks too closely because we had already busted through the ice on the way out. Bill Mattison said he was ready to push off and shook his head. ” I tried to tell you guys about this place, but you guys shamed me into it. “But How Would You Know”
We had a 24′ rake back mast, so we only needed 3 to set up the Skeeters. We considered ourselves so fortunate to get out of there that no one said a word about it as we went into the smoky tavern for a dipper.
Lake Hopatcong Ice Yacht Club Tune Up Night
Lake Hopatcong in New Jersey has a long ice sailing history and is building on its tradition by hosting a Tune-Up Night. You can find more information on their new Facebook Group.
We hope to see folks who like to race and folks who enjoy cruising in any kind of iceboat. It’s also for people who want to know more about iceboating and our long history of sailing on Lake Hopatcong.
We rented a church parish hall, big enough to set up – a couple DN’s (new and vintage) inside so we can talk about setups and tuning. Big enough to lay out a mini-course and catch up on rules basics.
Plus…we’ll have a runner sharpener on site and some guys who know how to use it. Bring your runners and stuff to sell or trade if you want. Heck, bring your boat and we’ll set it up inside.(Please bring pads to protect the gym floor)
And we’ll have chili, snacks, beer and soda.
All are welcome. No charge.
Friday 12/30
6:00 to 9:00 PM
St. Judes Church Parish Hall. 40 Maxim Dr, Hopatcong, NJ 07843 (Parish Hall is behind the church)

PRINCESS ALEXIA
Dutch Style Iceboats Archive
Via Facebook:
If the Netherlands is in your winter plans, visit Rotterdam’s Maritiem Museum to see an original stern-steerer, a classic Dutch iceboat on display. “Princess Alexia” was built in 1840 and is temporarily on display thanks to Stichting IJsschuiten Gouwzee.
State of the Lakes
After a week of below-zero temperatures, high winds, and snow, let’s review what Mother Nature left us. The good news is the big lakes were (mostly – see, Mendota) open and missed the snow. The east of Mendota froze on Friday, but as you can see, a large area remained open, at least as of December 24. Monona has an inconsistent freeze with numerous open areas. In other good news, Green Lake and Geneva were liquid as of December 24 and missed the snow.
After a week of bitter cold, the pendulum is swinging back to unseasonable warmth, with possible rain. Will the heat and rain bring the other lakes back online? Stay tuned!

Friendly reminder, we have a 4LIYC meeting tonight, December 21, 2022, at 6:30 PM. We are going ZOOM ONLY tonight. You should have received an email with the link. Contact me if you haven’t received it.
Lake Monona: First Freeze
The good news: Lake Monona froze over on December 19, 2022. The cold temperatures will likely keep it locked, unlike past years when the lake tended to go through freeze-and-thaw cycles.
The let’s wait-and-see news: The National Weather Service is keeping an eye on a system for Thursday and Friday. Maybe the 50 mph winds will push the snow to one side of the lake!
Ice Safety Review
From the NOAA Forecast Discussion
LONG TERM…(Issued 341 AM CST Mon Dec 19 2022)
Sustained winds of 30 to 35 mph, with gusts of 40 to 50 mph are currently expected, with the strongest winds near the Lake Michigan shoreline. With these winds coinciding with the time period of snowfall, am growing more concerned for whiteout conditions and very dangerous travel. Thus, will need to keep an eye on the potential need for any blizzard headlines.

2022 IRIYRA Championship Recap by Skip Dieball
What a fun weekend in Madison Feb 18-20. The collection of iceboating enthusiasts really encompassed the spec-
trum of abilities, which makes the experience so fun. The way folks light up when they have first ride…and the
hardened veterans that tweak their set up. Continue reading

See You Skimming

Michigan’s Ron Sherry set up these Skimmers on Lake St. Clair. In his article for the DN class newsletter Runner Tracks, “Be The Guy”, he wrote, “Be the guy that makes sure giving someone their first ice boat ride is a safe, exciting experience that they will tell all of their friends about.” Read the article here.
Last season, several 4LIYC members brought their Skimmer iceboats to the lake for fun and to easily give people their first taste of ice sailing. As of this week, Skimmer manufacturing and sales is now Wisconsin-based.
Via John Hayashi of Windward Boatworks, Princeton, WI
Windward Boatworks is excited to announce the acquisition of the Skimmer 45 Iceboat product line. The past owners, Jon and Nancy Cheris of Wind Power Products, manufactured and sold Skimmers for over forty years.
Windward Boatworks has been focusing on increasing ice sailing participation within the iceboating community and creating opportunities for summer sailors to try the sport. Everything pointed back to an iceboat priced comparable to other outdoor activities and easily shippable. Each time, Skimmer 45 became part of the discussion. That said, adding it to our line of products at Windward Boatworks made sense.
We envision an opportunity to get more iceboaters into the sport. For the more actively involved iceboaters, we are looking forward to re-establishing the Skimmer 45 National Organization and offering even more opportunities.
See You Skimming!

In the News 2: Bill Mattison in Dec Seahorse Magazine

Bill Mattison and his 75%
The second part of Carol Cronin’s Bill Mattison article in Seahorse Magazine has been published. “Carol Cronin continues her look back at the extraordinary life of a very extraordinary ‘yachtsman’… though such a plain description does not begin to touch the sides.”
The magazine is subscription based and you can purchase the December edition in print or digital format here.
Decades of continuous improvement
An unattributed quote in the book that Bill Mattison’s daughter Lynn produced for him puts the whole sport of iceboating into perspective. ‘It has been rumoured that iceboating is 75 per cent building them, 10 per cent talking about them, 10 per cent waiting around on the ice for the right conditions and five per cent actually sailing them.’ And her father enjoyed all of it.
