The Royal New Zealand Yacht Squadron is a yacht club at Westhaven Marina, 181 Westhaven Drive, in Grey Lynn, Auckland. It is one of the oldest yacht clubs in New Zealand and the current home of the America's Cup, and it has more than 2000 members. It is also the home of match racing in New Zealand, and it hosts national championships through the year.
The club runs a year-round racing calendar, from weeknight summer series and Sundowner Rum Race Fridays to the North Sails Winter Series. Motor yacht rallies and cruises take members around the Hauraki Gulf. Its Learn to Sail programme offers Level One, Level Two and Learn to Race courses in MRX keelboats. The Emirates Team New Zealand Youth Training Programme is for sailors aged 16 to 23. The club also hosts speaker series, quiz nights, picnics, a Ladies Mahjong group and live sports screenings. The Lighthouse Cafe is open seven days a week, with a weekend brunch menu, and the club says its upstairs Members Bar has the best harbour views in Auckland.
