NC Vouliagmeni

The club admits members and their guests and operates a marina, a waterskiing school, junior and Olympic competition sailing boats and facilities, an open-air, heated swimming pool, two rocky beaches, members' indoor and outdoor lounges, reading and conference rooms, a first-aid station, a gym, and an upscale restaurant. The club publishes a quarterly illustrated newsletter, the "Tríaina" (Τρίαινα, "Trident"), distributed free. As part of the celebrations for the club's seventy years, a memorial volume, "In Search of the Sporting Ideal", was published in 2008, in commemoration of the club's history. The volume chronicles the club's foundation and development, and pays particular tribute to the many club athletes who have taken part in Olympic Games and won Olympic medals. The most notable Olympic athlete to have been fostered at the club is windsurfer Nikolaos Kaklamanakis (gold medal, Atlanta Olympics, 1996, and silver medal, Athens Olympics, 2004).

The outdoor, heated pool hosts swimming, finswimming, synchronized swimming and water polo teams and the respective training schools for children. The club hosts two annual competition meetings for youngsters, the "Tzeláteia" swimming gala and the "Chatzitheodórou" water polo Cup, as well as annual water skiing and sailing events. In addition to regular training for its young athletes, the club organises training schools for beginners, open to all children interested in swimming, finswimming, water polo, boat sailing, windsurfing, synchronized swimming, and waterskiing. Four periods are offered per year in total, two (winter and spring) during school season and two more during the summer vacations.

Sports activities for members include aquarobics, aerobics, martial arts classes, long-distance sea swimming, water skiing, and Olympic and recreational sailing and windsurfing. The club also provides mooring for recreational boats owned by members. Several social events and functions are also held at the club, including concerts, art exhibitions, lectures, receptions, dinner parties, the Christmas Eve and New Year's Eve balls, the all-day "May Day at the Club" barbecue, and the midsummer "Full Moon Ball".

The club crest depicts a blue anchor set inside a white lifebuoy with eight red stripes; blue, white and red being the club colors.

The women's and men's water polo teams are a traditional force in European water polo and have won many Greek and several European Championships and Cups.
