The second largest Dragon shipyard in Switzerland is the Müller AG shipyard in Spiez on Lake Thun. Between 1946 and 1966, the shipyard built 66 Dragons in classic Carvel construction.
In 1954, Virgilio Muzzolini, known as “Muz”, the architect of Bern’s Wankdorf Stadium “The Miracle of Bern”, received his first Dragon GIOIA I Z 14 from the Müller AG shipyard. As early as 1955, the Lake Thun Yacht Club, TYC recognised the Dragon as a class and promoted it. In the years from 1956 to 1958, the Dragons LEVANTE Z 18, MILAN Z 19, LAFLORE Z 22, LAILA Z 23 and HOBBY Z 25 were launched on Lake Thun and sailed their first-class regattas.
In 1959/1960 “Muz” was a co-founder of the Lake Thun Dragon Fleet and 10 years later of the Swiss Dragon Fleet and successfully participated in national and international regattas with his yachts. After more than 65 years, the grandson of “Muz”, Paul Kreis, is also loyal to the Dragon Class and sails GIOIA SUI 317 in Switzerland at regattas and with the family. As Vice-President, he is firmly connected to the Swiss Dragon Fleet, like his grandfather.
