Dell is the founder, chairman and CEO of Dell Technologies computer IT company and also the money behind The Athens Group’s redevelopment of the Naples Beach Hotel & Golf Club, which closed in May and is proposed as the future home of a Four Seasons resort. Dell’s MSD Partners and MSD Capital control a luxury portfolio that includes the Boca Raton Resort & Club purchased two years ago. MSD, which has offices in New York, California and West Palm Beach, is a private investment firm established in 1998 to exclusively manage the assets of Michael Dell and his family.

Its Old Florida-style clubhouse with full-service restaurant and bar.

In an emailed statement, MSD says everything is “business as usual” for now.

Patrick Utter, senior vice president of Collier Enterprises, the club’s seller, confirmed the ownership change. “Collier Enterprises is proud of the stellar reputation established at The Old Collier Golf Club and Hamilton Harbor Yacht Club over their storied histories. Our company wishes the members and new owners all the best going forward, as we continue to focus on our network of business entities and endeavors.”

Hoffmann made an initial offer to buy the yacht club but backed out of the deal before purchasing the 18-hole championship golf club days later in North Naples. Situated along the Cocohatchee River, west of U.S. 41, the property originally was purchased for $7,299,000 in December 1998 by the Old Collier Golf Club Inc., an affiliate of Collier Enterprises.

The Hamilton Harbor marina property, 7065 Hamilton Ave., had last sold for $350,000 in July 1999, county property records show.
