The picturesque town of Marstrand lies just 45 minutes northwest of the large Swedish city of Gothenburg. Before arriving inScandinaviaI’d never heard of it. But probably I should have. As well as providing vacation homes for many ofSweden’s wealthiest families, Marstrand is also a Scandinavian yachting capital and the annual venue for the prestigious Match Cup Sweden sailing event. The small island of Marstrandsön is separated from the mainland by a wide channel and is dominated by an imposing 17th-century hilltop fortress.
