The fledging club engaged Devereux Emmet to lay out an 18-hole golf course, which he carved out in true links style, much of it on land reclaimed from the marshes. For their clubhouse, the membership modernized Auerbach’s three story Victorian country estate. The club was easily accessible by boat via the canals and nearby Lake Kath Ellen, a deep body of water that provided a fine anchorage for motor boats.

The club fell on hard times, and eventually the course and clubhouse fell into disrepair. The downward spiral continued until 1960, when residents of Hewlett Harbor purchased the club from the remaining members. Since that time the club has become one of the most prominent clubs in the Metropolitan area.

Through the years the club prospered and was able to do a vast renovation in the spring of 1994. This renovation generated a total cost of $4.5 million dollars, allowing new facilities such as the health club, main offices, and refurbished living room. In addition the club was able to expand the mixed grill, dining room, terrace, and main bar. In light of these changes, Seawane is one of the most exquisite clubs on Long Island. The Seawane is notorious for its fine dining, outstanding golf, invigorating pools, pristine tennis courts, and superb athletic training center.

Seawane has over 225 members, and many families have been members for three or four generations. Each year the club is the host of the Richardson Memorial, which honors the late William D. Richardson, a reporter for the New York Times from 1921 to 1957.
