Input: Question: Which continent where the 420 class racing vessels are popular currently has the larger population? Passage:Yachting has a long and prolific history in the area. New Silver Anchorage was dredged from Wild Harbor in the 1920s to shelter Beetle Cat boats which had become popular among the Cape Cod elite. Prior to the Second World War organized sailing flourished out of Wild Harbor, however U-Boat hysteria during the war led to dwindling popularity. On August 30, 1953, the Wild Harbor Yacht Club was formed on Wickertree Road to primarily serve New Silver and its constituent communities. The Club was incorporated by the United States Sailing Association the following year. A Widgeon fleet was organized in 1979 which brought the sport of sailing back into regional popularity. The club clinched the Southern Massachusetts Beetle Cat championship in 1981, 1982, 1984, 1985, 1986, 1987, and 1989. In 1990 the club focused its junior sailing on the new 420 class racing vessels which were already popular in Europe and Australia. Wild Harbor is a regional powerhouse and dominates the north shore of Buzzards Bay and competes competitively in the Southern Massachusetts Sailing Grand Prix. Wild Harbor has produced three collegiate all-Americans and a member of the 2000 US International 470 team.
