From the club website:

Sankaty Head Golf Club is a private golf club with tennis and beach facilities that provide its members and their families with first-rate recreational and social activities in an understated and informal atmosphere.

The Club prides itself on the diversity of its membership, drawing on a wide range of Nantucket’s population, from summer residents to year-round Nantucketers. As a friendly refuge from everyday life, the Club and its camaraderie play an important part in the experience of its members. The Club sees itself as an island resource and seeks to be a responsible member of the Nantucket community by sharing its facilities with year-round residents and Island visitors in the off season, and by offering the use of its facilities to Island charities and other organizations.

The Club’s primary focus is golf. The course is renowned as an outstanding example of links style golf architecture and is surrounded by open land and wildlife. The membership values its natural beauty and serenity as much as the golf challenge it presents. Golf at Sankaty is enhanced by the Caddy Camp that is supported by members of the club through the Sankaty Head Foundation. This camp, which benefits young people from all over the country with its recreational activities and scholarship program, is the last of its kind and is a fundamental part of the Sankaty golfing tradition.
