International Skeeter Association
The world’s fastest iceboats.

ISA Regatta

The ISA regatta was first sailed in 1940.


The only rules for the Skeeter class are sail area and configuration.
This class thrives on the latest state-of-the-art technology.

Fastest Sail Powered Boats on the Planet

Skeeters are the “Formula One” in the world of ice yacht racing.

B Skeeters

B Skeeters maintain the classic lines of the wooden Skeeter.


The Nite class has competed as a separate class in the ISA since 1996.

Dan Clapp NSIBYC: 9 time champion
Buddy Melges SIBC: 7 time champion


“Sufficiently committed skippers find the greatest challenge in these boats,
where design, building, and maintenance skills share equal roles with sailing ability.” Charles Johnson

C Skeeter

Sail area 40-75 square feet and mast less than 20 feet 3 inches from deck to top of mast.

International Skeeter Association Regatta

The International Skeeter Association (ISA) was organized in the late 1930s and the first ISA regatta was sailed in 1940. Skeeters were developed on Geneva Lake in Wisconsin. They are piloted by a single skipper and steer from the front of the boat as opposed to the original iceboats which were crewed by two or more and steered from the rear.

The Skeeter is the “Formula One” of ice yachting, a wide open development class where state-of-the-art sailing is seen annually. The only restriction on the Skeeter builder is a 75 square foot sail maximum sail area. While the basic configuration for successful E Skeeters has long been established, significant design improvements have been developed within the Four Lakes fleet. Taller rigs and rear seat Skeeters designed and built by 4LIYC members Bill Mattison and Paul Krueger have brought world championship titles to Madison skippers. In 1989, New Jersey’s Dan Clapp took the ice boating world by storm with his first front-seater and dominated the ISA regatta during the 1990s. Skeeter builders are adept with high tech materials like carbon fiber, and Kevlar. The super powerful Skeeters are the fastest boats on the ice. Sufficiently committed skippers find the greatest challenge in these boats, where design, building, and maintenance skills share equal roles with sailing ability

C-Skeeter Polish Championship

The Western Region of the DN Class (WI, MN, IL, IA, IN, UP of MI) is hosting the DN World & North American Championship in just a few days. Ice sailors from Poland and Sweden are here to train on Lake Kegonsa. The regatta site information will be announced on January 18, 2023, on Regatta information.

Boat preparations are underway for the first-ever C-Skeeter Polish Match Racing Championship. Current DN World Champion, Robert Graczyk, will face off with former DN World Champion, Tomek Zakrzewski, on Lake Kegonsa in Stoughton, Wisconsin this Wednesday, January 18. Weather permitting, of course. At stake is a meal of Polish delicacies including pirogies and Polish sausage. But none of that cold soup. The loser will treat the winner and the boat owners/race committee at the prize giving ceremony, which will take place sometime during the ‘23 DN Worlds/North Americans.

To date, only the Black Ice/Loren ipsum camp has responded to requests for information about boat prep. The Drifter camp remains shielded under a cloak of secrecy, no doubt working on another traveler-like innovation to create an unfair advantage.

To make sure the race track is level, the two competitors will trade boats after each race, and the championship will conclude after an even number of races. Clearly the Drifter camp strategists have failed to read the Notice of Race and Sailing Instructions.

A stronger breeze made it a wind hat trick on day three of the ISA and Renegade championships on Lake Kegonsa. The A & B Skeeters elected to watch the Nites and Renegades take to the course for spirited racing. All agreed they couldn’t remember when Mother Nature blessed the ISA with three sailable days. Renegaders discussed how this ISA was a record for them in the number of races (8.)

Many thanks to the Race Committee, including
Joe Norton, Jerry Simon, Scott Goetz, Paul McMillan, Afan Ottenhemier, and 4LIYC Commodore Daniel Hearn, who helped to organize the equipment. Also, many thanks to Ann Foeller, who tabulated remotely from Lake Erie’s shores and is a Toledo Ice Yacht Club member. And thank you to the many competitors who didn’t hesitate to pick up starting blocks, call numbers, and anything else to make the regatta run smoothly.

ISA & Renegade Championship: Day 3 AM Report

The wind made another welcomed appearance on the second day of the ISA & Renegade Championship. The A, B, C Skeeters, and the Renegades sailed three races in moderate breeze. The Nites were only able to complete two races today. The weather mark came down in the first Nite race of the day because someone hit it (and did the right thing by telling the Race Committee, thank you!) The race was black-flagged, the mark repaired, and then the A Skeeters began the rotation.

Nite points leader Tom Sweitzer broke his mast in the first Nite race. Luckily, the race was black-flagged, and he carries a spare mast. Tom was on the starting line for the final Nite race of the day and came in second to David Navin

The Nite fleet starts first in the rotation today at 9:30 AM (to make up their 6th race from Saturday), and then the regular order will resume.

First, let’s get the business out of the way. ATTENTION ATTENTION ATTENTION

The 2023 ISA Annual meeting will be in the mooring area tomorrow morning, Saturday January 14th, prior to the first race. Fleet representatives take note.

Steve Schalk
ISA Secretary/Treasurer

A perfect regatta day. Wind, hard ice; what more can we ask for?  Three races in each fleet, A Skeeter, B Skeeter, C Skeeter, Renegade, and Nite.
The wind was out of the north and “juicy” early in the morning but true to the forecast, calmed down a bit. Southerly breeze for Saturday means the starting area should be visible from Springer’s Bar & Restaurant big picture windows. The A Skeeter fleet will start the rotation on Saturday when the flag drops at 9:30 AM.  Follow the regatta on our 4LIYC Facebook page for live video feeds.

Mary Jane Schalk: Ready For Some Time Away

Steve and Mary Jane Schalk

Via Mary Jane Schalk, Fontana, WI

Hey Ice boat racers,

I just want to thank all of you for so many years of helping me with one of the coolest things I have ever done. We have all been through so much together.

I think I started scoring ice boat regatta’s back in the 90’s. Remember way back then and I did all the tabulating with a pencil and a very long sheet of paper. There were some interesting stories and memorable situations back then! It took a while but so worth it to graduate into computer scoring.

I had so many great people to work with. First of all many of you sailors were my callers, and then I had Renate Intini, Julie Jankowski, and then Deb to work with. As you know Deb and I had some pretty good and crazy times together. We could figure out ways to entertain ourselves during a postponement, and had way more fun that we probably should have!!! Thanks Deb for all the fun times. I would also like to thank Shari Lundberg for teaching me in the beginning all about scoring and tabulating.

I stopped scoring from the ice to help take care of my mom and then we had so many cats that needed care like insulin shots twice a day, fluid under the skin, and medicine that – that kept me from coming back. But I was then able to do the tabulating from home.

I was still a helper by arranging hotels, banquets, and meetings for regattas. I drew for your starting positions from home and called them into Deb. Deb would take a picture of your finishes and call them in or send them to me. Now with me being able to post to the web page on a good day I could score the race and get it posted before the last finisher got out of his boat. That is way cool.

But I am ready for some time away. I have lots of plans for some fun activities while the regattas are on. Maybe I’ll just go down and visit some other retired ice boaters like Gary and Kenny Kessler. Now that would be fun!!! Deb asked one of the DN tabulators, Ann Foeller of the Toledo Ice Yacht Club, if she would score the ISA and NW regattas and she agreed. I wouldn’t leave without a replacement.

I am so happy to have met so many really cool and fun ice boaters. We have had lots of fun times, and made great memories. I can hardly wait for a regatta to come to Geneva Lake, as then I can hang with you all on the ice, and not be stuck at home in front of the computer.

Have fun everyone, be careful on the ice, and sail fast,
BTW I am sharing my favorite version of Steve’s iceboat song. I’d say it a pretty good one! LINK

Via Jane Pegel:

Mary Jane was a significant member of the Lake Geneva YC race committee. She also is a competitive sailor. She handled the front end of Steve’s E scow and his J-24.

She trimmed jib on my class M scow and helped me win Inland Lake YA championships and Blue Chips. She is no doubt, an exceptional woman who is happy to be “involved”.


Mary Jane Schalk has been a crucial part of North American iceboating racing, and she’s decided to take a well-earned retirement. You may have seen her smiling face on the ice of Lake Geneva, but she was deeply involved behind the scenes in every Northwest, ISA, Renegade, and many Nite regattas for 30 years. She took care of numerous organizational details so that you ice sailors could book a room, attend a banquet, see your regatta scores, receive your trophies, and pursue your passion for iceboat racing.

MJ and I share many good memories. One of my best was driving on Geneva back to the Fontana landing towards the sunset. We were singing a silly, fun song at the top of our lungs that we had made up about the late Renegade sailor, Arlyn Lafortune, to the marching chant O-Ee-Yah! Eoh-Ah from the Wizard of Oz. (Yeah, you had to be there…) We both probably enjoyed too much red wine later that night but were always ready for the next day. I know she’ll continue to be the first person I call when I have a funny story to share. – Deb Whitehorse

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.

Everything You Want to Know About Rear-Seat Skeeters

Bill Mattison wrote this article for Yacht Racing and Cruising magazine in 1981 in the heyday of the rear-seat Class A Skeeter, a few years before the dawn of the cockpit forward style. Hundreds of these rear-seaters are still out there. Print this article and keep it with the boat if you have one.

The word “iceboater” should be listed as a synonym for “dedication.”

The ISA Fast Second Update 2-22-22

Previous: The ISA Fast Second
Via Past Champions Iceboat Shop Ken Whitehorse:

Second day of M165 repairs: The inside bulkhead was reinforced with 1″ by 4″ by 11″ oak. Note the blow out at upper left. The deck was reinforced with three layers of carbon fiber. Next, we will mount the pulleys.  Paul “Samson” Krueger will be able to pull the sheet rope with great confidence that the pulley system is secure!
P.S.  (Past Champs Iceboat Shop has no warranty on any repairs)
