The Stradivari Mk I, designed and built by Hasse Malmsten was concived after having entered the class in 1987 by ordering the plans for the Norlin Mk III and built a number of them in cold moulded wood. After designing the boat in 1995-96 the sailing prototype was sailing for the first time in 1997. After some test sailing confirming the performance predicted, a set of moulds where built and 11 boats where built from these moulds.
Though small in numbers the design has proved to be competitive at the highest lever with a WC title as the best result in 2012. Though the boats are pretty old by now, the choice of materials and high build standard keeps a number of them going, achieving podium places in major regattas frequently.
If you can find a used one it's probably a bang for the buck if you want to go racing.
