Børge Quorning was one of the last old-school boat builders and has probably built the most different types of boats and vessels in the neighbouring country. His stations included shipyards such as Børresen, Walsted and Coronet, smaller companies such as Pedersen & Thuesen, Molich, Lindø and Fanøe. On a trip to Canada, he got to know and love the trimarans, which were still relatively uncommon, and built them years later in his own shipyard in Jutland, which he founded in 1967.
The first Tri sold off the drawing board - and remained the last for years, the time was not yet ripe. The shipyard offered its Trident 37 at trade fairs, the interest was huge, but nobody wanted to buy. During the day, the Quornings built motorboats on the Kolding Fjord, and in the evenings they devoted themselves to their passion, the Tris. The capsize together with his sailing friend Paul Elvstrøm, on whose Olympic Finn Quorning had already worked, was legendary. The two had to spend a night on the upturned boat.
His son Jens has been running the shipyard for a long time, and with great success. Alongside Corsair Marine, Quorning Boats is one of the leading manufacturers of performance trimarans. The company became big thanks to the swing-wing system, which reduced the width of the boats to harbour and trailer-friendly dimensions, thus eliminating one of their major disadvantages. Another booster for the fast racers was the 1985 Round Britian Race, which Børge's sons Jens and Eric completed with two boats in first and second place. Dragonfly-Tris have also won the European Yacht of the Year title several times.
