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

…and the second domino falls.
The ISA race committee after reviewing the morning ice check and the upcoming weather forecasts has decided to postpone the 2026 ISA one week to January 23-25. The surface of Lake Kegonsa roughened up in the flash freeze last night after the very warm temperatures. The NOAA forecast has visibility-blocking snow showers on both Friday and Saturday, and all forecasts rule out Sunday as never getting to minimum temperatures. The Committee believes there is time to wait for better conditions. The next update will be Sunday evening, January 18 following the 7 pm conference call.

Regatta Logic, Explained

Wondering how can three things be true at the same time, three regattas (the Northwest, ISA, and Nite Nationals) tentatively called on for the same weekend?
For January 16–18, all three are in play and they are connected. Multiple fleets are trying to do the right thing without stepping on each other.
Here’s the flow-chart version, in words.
Step 1: Look North
The Northwest Ice Yachting Association Regatta is tentatively on for Lake Winnebago at Fond du Lac, starting Friday, January 16.
Classes sailing at the Northwest include DN, Renegade, Stern Steerer A, B, C, and D, and A, B, and C Skeeters.
The final call will be made by noon on Wednesday, January 14, after ice and forecast checks.
This is the first domino.
Step 2: If the Northwest Is ON
NIYA sails in Fond du Lac.
The International Skeeter Association does not sail on Lake Kegonsa.
The Nite Nationals continue watching Kegonsa to determine whether Nationals conditions exist.
Step 3: If the Northwest Is OFF
Everything shifts south.
The International Skeeter Association Regatta is tentatively on for Lake Kegonsa, but only if the Northwest is postponed.
ISA racing includes A, B, and C Skeeters, Nites, and Renegade classes.
The NIYA decision is announced at 11:00 am Wednesday.
The ISA decision follows at 11:30 am.
By noon Wednesday, it will be clear whether the ISA is on and where.
Step 4: The Nite Nationals Decision
Nite Nationals are tentatively scheduled for January 16–18 on Lake Kegonsa, for either two or three days.
This is the National Championship for the Nite class.
If the ISA is officially called on, the ISA regatta takes precedence.
The Nite Board will provide updates after 3:30 pm Wednesday, with a final decision by early evening, based on ice conditions.
In plain English:
Wednesday is everything.
The Northwest decides first.
ISA reacts to the Northwest.
The Nite fleet watches Kegonsa and defers to ISA if needed.
By Wednesday night, the picture should be clear.
Regatta Watch: 2026 ISA Tentatively Called ON for Lake Kegonsa Jan 16-18

International Skeeter Association Home
The 2026 International Skeeter Association Regatta is tentatively called on for Lake Kegonsa for Friday January 16th, but only if the Northwestern Regatta at Fond Du Lac is postponed on Wednesday the 14th.
The final call on Wednesday for the NIYA is being held at 11 am and the ISA at 11:30 am, so by noon Wednesday the 14th, the call will be made as to which Regatta is on and where.

There is no suitable ice available for a Championship regatta for January 9th.
The next scheduled weekend is concurrent with the first possible date for the Northwestern Ice Yachting Championship. If the Northwest is held on those dates, the ISA will be postponed. Next update is January 11, 2026.

Unofficial Eye Opener and New Year’s Speed on Lake Kegonsa
LINK TO VIDEO
Lake Kegonsa has seen serious traffic this week.
Multiple DN World Champion Matt Struble arrived Monday to get acquainted with his new Class A Skeeter, recently acquired from Tom Hyslop. (Previously: The Bubble Expands) The boat is a Clapp build with a solid pedigree. Matt spent two long days in Daniel Hearn’s shop learning the boat inside and out, and quickly learned that sharpening Skeeter runners is heavier work and a much longer commitment than anything he’s used to with DN runners.
On Thursday, the Skeeter fleet welcomed him on Lake Kegonsa. Ken Whitehorse and Mark Isabell set up under the watchful eye of Paul Krueger, with pit help from Daniel Hearn and Damien Luyet. Conditions weren’t ideal, but they managed a few solid rides. For Matt, it was exactly what he needed, time on the boat, learning how it behaves. Ken Whitehorse sent in this report from the day:
New Year Eye Opener – Wisconsin Skeeter Racing
Results:
1st – M197 (Ken Whitehorse)
2nd – Matt Struble (sailing with an “M” on his usual DN number for now)
Mark Isabell – DNSTwo races were sailed. M197 finished first in both. Matt followed, with Isabell DNS. Speeds were good.
M197 carried 50 pounds of lead in the trunk, a winning setup that helped punch through the drifts. Tried to keep that quiet.
Excellent hard ice under the snow. A great day of tuning and racing. Best of all, the boats are safe and back on the trailers.
Huge thanks to Daniel Hearn and Damien Luyet for organizing the day. We’re lucky to have club members like them.
Matt was offered $100, a wheel of cheddar, and a Packers hat to put an “M” on his sails. Mostly kidding. Mostly. Also trying to stack our roster for the Ice Yacht Challenge Pennant of America.
Ken Whitehorse M197
Midweek also brought a visit from the Geneva Nite gang. Olympic sailor Paris Henken, Harry Melges IV, Kyle Navin, and RJ Porter were among several Nites that rolled in on New Year’s Eve and ripped it up on Lake Kegonsa. Two future 4LIYC members, Dash and Enzo, made their debut on the ice, sailing all day with their grandfather, Daniel Hearn. Geneva Nites pushing off on Lake Kegonsa (short video)

2025 NOTICE OF RACE
ISA HOME PAGE
Via ISA Secretary/Treasurer Steve Schalk:
The ISA & Renegade Championship Race Committee is cranking back up to find the location for the postponed 2025 ISA. The conference calls restart on November 30th. There is a cold front moving through Minnesota as I write this, with none of the sites yet frozen, so the current snow is just falling in open water. The following cold will close up the lakes and allow for the search to begin. Minnewaska and Battle Lakes are favored sites with their launch facilities.
The ISA Race Chairman believes that it should be possible for a DN Western Challenge by December 5th, with the two following weekends available for the ISA. Of course the weather will dictate the outcome. We will post Sunday 7 pm updates starting November 30th.

The Bubble Expands & a World Champion Joins the Skeeter Fleet

Two Clapp-built Class A Skeeters with deep pedigrees.
The world’s fastest iceboats, the Class A Skeeters, the Formula One of iceboat racing, have grown their fleet this season with two new Clapp-built additions. Both boats come from the shop of Dan Clapp, innovator of the renowned bubble boat design that transformed Skeeter performance back in the 1990s.
PREDATOR Finds a New Home
The Class A Skeeter PREDATOR has a new owner, Fritz Good of Pewaukee, well known in Scow sailing circles from his years sailing on Pewaukee Lake. PREDATOR was most recently owned by Rob Evans, from whom Good acquired the boat. Welcome to the fleet, Fritz, and congratulations on bringing PREDATOR back on the ice.
Clapp shared some of the boat’s storied history:
“PREDATOR was the first bubble boat, COMING ATTRACTION. I won my first ISA with this boat on Lake Geneva in 1991. Afterwards, I sold it to Art Apy, who renamed it GOTCHA. A few years later, the boat was sold to Rick Stavola and became MONA LISA. Rick raced it successfully for many years before selling it to Rob Marsh, who renamed it ILLUSION and modified the rear deck to match the newer slant-back design. Eventually, the boat was sold out West.”
Struble Steps in to the Bubble
Perhaps the biggest buzz of the season comes from the DN ranks. DN World Champion Matt Struble has thrown his helmet into the Class A Skeeter ring, purchasing the bright yellow AMPHETAMINE from Pewaukee’s Tom Hyslop.
Clapp recalls building the boat:
The yellow boat was built for Jack Jacobs. It was the first slant-back-deck bubble boat. I built it alongside BALLISTIC (for Bill Stavola) and MADJAKE (for myself) around 1998. It originally had a 26-foot mast and 22-foot plank. Later, Jack bought my all-carbon MADJAKE and renamed it MERLIN. He wanted both boats to be identical, so I built him a new mast and plank for MERLIN that matched the carbon boat. I then took the original shorter mast and plank in trade, painted them orange, and used them on INSANITY for many years. Tom Hyslop bought MERLIN from Jack and renamed it AMPHETAMINE II or III. He experimented with mast and plank lengths before settling on a setup with a new mast by Jay Yaeso and a 22-foot plank I made for him.
Now the distinctive bright yellow Skeeter returns to the line with Struble at the helm, a DN sailor stepping up to the elite level of A Skeeters. Struble’s arrival in the Skeeter fleet is sure to turn heads and raise the competitive bar.

Dan writes, “Here’s a Gretchen Dorian photo of me at Lake Geneva following Buddy around in the Northwest. I ended up 2nd. No matter what I did, I couldn’t beat him that day….on his home ice. Jack (Jacobs) owned the boat at the time. I was “testing” the new 30’ mast and 25’ plank.”

Burly Brellinthin Still Throwing Heat

Burly Brellinthin throws out the first pitch at the Milwaukee Brewers game on September 4, 2025.
Not long ago, we shared the story of iceboater Skeeter Iceboat Club’s Mel Jones, who left his mark as an Indy 500 driver back in 1927. Nearly a century later, another iceboater has stepped into the major league (literally!) sports spotlight. The Skeeter Iceboat Club’s own Burly Brellenthin, fresh off celebrating his 100th birthday, threw out the ceremonial first pitch at the Milwaukee Brewers* game on Thursday, September 4, 2025. A WWII veteran from Lake Geneva, Burly was honored as part of the 80th anniversary of the end of World War II.
Tip of the Helmet: Greg Whitehorse
* The Milwaukee Brewers are on an historic hot streak, recently setting a franchise record with their 14th consecutive win, following a previous 11-game streak just weeks prior.

Ken Whitehorse Shares Family History for WPT’s Hometown Stories

Ken Whitehorse adds the finishing touches to a display honoring the Whitehorse family’s legacy in iceboat and auto racing, featuring historic trophies and family photos.
Skeeter sailor Ken Whitehorse recently participated in an early-stage gathering hosted by Wisconsin Public Television for their upcoming documentary, Wisconsin Hometown Stories: Madison. The two-hour program will explore Madison’s history, focusing on Teejop — the Ho-Chunk name for this region, meaning “Four Lakes.”
WPT is working closely with members of the Ho-Chunk Nation to ensure their stories and perspectives are central to the project. WPT invited Ho-Chunk community members to share their memories of Madison during the event. Ken curated a presentation on the Whitehorse family’s deep involvement in iceboat and auto racing. He displayed several historic trophies — including the Ice Yacht Challenge Pennant, won by AJ Whitehorse in the 1980s — and noted, “Whitehorse names are all over these trophies.” It was a reminder of the family’s long-standing presence in Madison’s sporting culture. We were also blessed by the presence of Ken’s father, Walter Whitehorse — a longtime 4LIYC Skeeter sailor — who recently celebrated his 100th birthday.
A few days earlier, I also spoke with the producer about Madison’s iceboating history and shared memories of my late husband, Harry Whitehorse, whose legacy as an artist and iceboater continues to shape how we remember this place.
