Event: St. Moritz Match Race
Boat: Streamline 7.15
Designer: Judel/Vrolijk (2002)


The Streamline 7.15 (23-footer) comes from the drafting table of renowned German yacht designers Judel/Vrolijk. For some 25 years the duo has designed a number of successful big boats to the IOR and IMS rating rules, and Ralf Vrolijk was a designer for Team Alinghi when it won the America’s Cup in 2003.

According to Freidrich Judel, the Streamline was conceived as a keel boat for regattas and sailors of sporty ambition. The hull shape is optimized for upwind stability, which is enhanced by the large 440-pound (250-kilogram) ballast bulb and two persons hiking on the trapeze. The Streamline displaces 1,322 pounds (600 kilograms). Judel says the boat is “extraordinarily fast downwind thanks to the generous spinnaker,” which measures 548 square feet (51 square meters).

The Streamline is built by German builder Leonhard Mader, a builder of fine one-designs such as the Star, Flying Dutchman and Yngling. All hull forms were computer cut to a standard within one-tenth of a millimeter. The hull is a sandwich, with epoxy laid over a foam core.
