The timeless design of the Hatteras Yacht Sport meets modern independence in this well-equipped 1979 3-stateroom / 3-head layout is an ideal platform for island cruising, liveaboard comfort, or extended time on the hook.

Built during Hatteras’ legendary era of heavy fiberglass construction, this Yacht Sport delivers the solid ride and classic lines serious boaters appreciate. Inside, the 3/3 layout offers excellent separation and privacy. A spacious master stateroom, two comfortable guest cabins, and two full heads. The salon provides generous natural light and an inviting space to relax after a day underway.

What truly sets this vessel apart is its upgraded self-sufficiency.

For island hopping or extended stays in remote anchorages, this is a major advantage to having quiet nights, reduced fuel burn, and true independence.

Additional upgrades and improvements throughout the vessel enhance both reliability and livability, making her a practical option for someone seeking classic Hatteras quality without the price tag of newer yachts.
