The open fleet includes any sailboat design not included in the racing fleets, such as the Jet 14, Albacore, Catamarans, Precision, Vanguard 15, and Laser.  Open fleets can race with a separate start during Sunday 1:30PM race series, and in the Little Brown Jug Regatta held every year on July 4th.  Boats of different classes are scored on a handicapped system.

One example is the Jet 14, developed in 1955, is a 14-foot, planing, one-design, two-person racing dinghy.  The rig and sail plans are based on the Snipe, with spinnaker added in 1970.  The design has proven to be rugged and long-lived with early wooden hulls still competitive against newer fiberglass hulls.  The balance is such that crew weight and athletic ability are not critically important with the result that sailors aged 14 to over 70 can be competitive at all regatta levels.  The class association website is www.jet14.com.
