By any standard the International One Design class - conceived in 1935 by Cornelius “Corny” Shields and brought to life by Norwegian yacht designer and master boat builder Bjarne Aas - has been a huge and international success. By the class’s 75th anniversary in 2012, at least 235 of these beautiful thoroughbreds had been built for fleets in Norway, Sweden, UK, Bermuda, USA and Canada. The British fleet has circulated mostly anticlockwise since 1939: at Burnham-on Crouch, then Cowes, then on the Forth and on the Clyde in Scotland, and more recently in Cornwall where MITZI was based 2005-2021. In current ownership MITZI completed the circumnavigation and is now based in Suffolk. Since 2003 she has arguably received the best professional care of any UK IOD in recent years, including major structural work in 2008, and now may be unique in having her own road-legal trailer. MITZI is ready to go: in fleet; as an incredibly economic, well-proven handicap racer; or as a delightful weekender easily sailed by two people – always with the IOD’s renowned speed, seaworthiness, and of course beauty.

Designed by Bjarne Aas in 1935 at the request of “Corny” Shields Jr. - the legendary American yachtsman - as a slightly smaller, lighter displacement and more comfortable one-design version of the successful Bjarne Aas-designed and built 6-Meter, SAGA.

The result is a beautiful reminder of yachting’s “golden age” with traditional metre-boat long overhangs, graceful sheer, deep, narrow hull, and lofty rig. Described by Classic Boat Magazine in 1990 as “the waterborne equivalent of a vintage Bentley”, the IODs were the first class to be awarded International Classic Yacht status by the International Sailing Federation (ISAF).

Many of the great America's Cup skippers of previous years chose to race IODs, including Ted Hood, and Bus Mosbacher, Long Island’s IOD champion eight years in a row. IODs are used for the King Edward VII Gold Cup event in Bermuda, the oldest match racing event in the world; past winners include Russell Coutts, Chris Dickson, Ben Ainslie and James Spithill.

IODs are actively raced in twelve local fleets in North America and Europe, representatives of which compete annually in a World Championship, the venue of which rotates around the fleets. IODs are also sailed in classic regattas, including Cannes Régates Royales and Les Voiles de Saint-Tropez Classic Regatta, and in the British Classic Yacht Club regatta at Cowes.

While IODs can be raced competitively, they are also wonderful day-sailors even in less sheltered waters, and it is this, together with their graceful classic lines, which makes them so attractive to many owners who enjoy just sailing.



The UK IOD fleet began on England's east coast just before the Second World War at the Royal Corinthian Yacht Club, Burnham-on-Crouch, and when the RCYC opened a "southern" clubhouse at Cowes in 1948 the class regrouped and flourished there through the 1950s and 60s.

MITZI was one of the last boats commissioned from Bjarne Aas for the by then c.20-strong Cowes fleet in 1958 by Air Vice Marshall John Grandy, and owned by him until 1961, probably during a period when he was more UK based than in the 1950s, and would be through the 1960s en-route to becoming Marshall of the Royal Air Force, Sir John Grandy, one or the leaders in the management of the Cold War. In 1961 her ownership at Cowes passed to UK-based Dane, Hans Heyman.

Under the ownership of Harry Holmes, in 1969 MITZI became the second boat to move north to the Royal Forth Yacht Club at Granton near Edinburgh where the UK fleet became established through the 1970s and into the early 1980s, afterwards splitting between the Firth of Forth and the Firth of Clyde and eventually strongest on the Clyde, culminating in the World Championships at Royal Northern & Clyde YC in 1990 and 1998. MITZI participated in all six Scottish-based IOD Worlds between 1975 and 1998. She was a west coast boat from 1987, still owned by Harry Holmes with Charles Connor and K. Maclintosh, followed by Campbell McAuley from 1994.

The Clyde fleet declined after the 1990 Worlds with many of the remaining active IODs gradually returning south, to St. Mawes in Cornwall where a small fleet of these gorgeous yachts has been active through the early years of the 21st Century.

- Scottish Fleet Champion 1997 and 1999
- Participated in the Worlds at Royal Forth YC: 1975, 1979, 1984
- Participated in the Worlds at Royal Northern & Clyde YC: 1990 & 1998

In present ownership, MITZI has placed in the top 3 in the Classics Class at all events attended with several line honours and first places on corrected time.
