Since 1908 the Skerry Cruiser has been launched in various classes from 15 to 150 m2 of measured sail area. Admired for its elegance and agility, it was soon appreciated outside Sweden as well. Due to his international contacts, Knud Reimers developed a 22 sqm class boat for a client in Chicago in 1953. Soon, a fleet followed.

The Skerrycruiser maximizes speed by maximizing length, and the sailors from Chicago Yacht Club were eager racers. To the surprise of the local sailors, Reimers designed a fairly short boat, tailored to the choppy water pattern on the shallow Lake Michigan. First it was complained that “Reimers would not listen”. Soon it was understood.

Seven boats were built in wood by Kungsörs Båtvarv in Sweden, constructed of mahogany planks on oak frames, and shipped to the US. Four boats have followed since 1967 in the then new boatbuilding material, fiberglass, in Florida at Creekmore Boats. This became the 22 m2 One Design class named Udell.

The Chicago Yacht Club documents 15 Udell 22 championships from 1962 to 1976 with boats named Auf Wiedersehen, Eclipse, Focus, Grail, Kona, Krista, Ondine, Skipjack, Valkyrie, Vinst, and Windjack. Below is an attempt to document the fleet. Identified sail numbers are marked bold.

Udell 22 National Championship 1991

In 1991 the Chicago Yacht Club hosted a national championship for the class being developed for some club members, which existed at Belmont Harbor. The Udell class consisted of ten beautiful 22 square metre one designs. The class was an official U.S.Y.R.U. National Class but had never before held a national championship regatta. “The regatta was somewhat limited because of insufficient winds to get the Friday evening race off and too much wind to sail the Saturday afternoon race. The championship was decided in a blustery, wet race on Saturday and a race under ideal conditions on Sunday.”

It is remarkable that there was a small fleet regularly racing on Lake Michigan, which became the template for the modern Cruising Square Metre Boat variants with slightly risen freeboard and a little more comfort below deck: in particular, the S30, followed by the Swede 55 and Jubilee S40, and boats by other designers.

For the windy waters of shallow Lake Michigan with short and steep waves, Reimers designed a rather short 22 sqm boat measuring 36 × 6.56 ft (11 × 2 m) with a raised freeboard and a stretched cabin. In 1963, this became the American Udell 22 One Design. A little later, in 1967, Reimers revised his plans for GRP series production with a slightly raised cabin. It is obvious that Reimers used this concept to develop the S30 with a higher cabin superstructure. Even the windshield-like spray cap at the end of the the cabin appears in his S30 design a few years later.

The Udell 22 is one of several attempts to create a one design class, manufactured at favourable costs, largely compliant to the Swedish Rule or as cruising offspring.

  • the Nordic 22 m2 Class since 1922
  • various Mälarboats of 15, 22, 25, and 30 m2 since 1930
  • the 15 m2 Neptun Cruiser since 1938
  • the 30 m2 Bijou-Type for Lake Constance since 1967
  • various Crusing Variants since the Seventies.
