This 2007 Sea Ray 310 Sundancer offers the space, comfort and versatility that have made Sea Ray’s Sundancer series a popular choice for family cruising. Measuring more than 33 feet overall with a generous 10-foot-5-inch beam, the 310 provides substantial cockpit and cabin space while remaining manageable around the marina.

This boat has benefited from several meaningful upgrades, including modern Raymarine navigation equipment, a new full canvas package, four new AGM batteries and extensive mechanical and cosmetic work completed in 2026. A bow thruster provides additional control when docking, while the twin-engine sterndrive configuration delivers responsive handling and comfortable cruising performance.

Spacious Cockpit and Accommodations

The cockpit is arranged for entertaining, with generous seating, a wet bar and convenient access to the large integrated swim platform. Sea Ray’s foldaway transom seat provides additional aft-facing seating without permanently occupying the platform, while the walk-through windshield allows safe and easy access to the foredeck.

Below deck, the open cabin benefits from oversized hull windows, good headroom and a practical layout for weekends aboard. Accommodations include a forward double berth, a convertible mid-cabin conversation area and a convertible salon sofa. The galley is equipped with a refrigerator, recessed two-burner stove, microwave, stainless-steel sink and ample storage.

A private enclosed head includes a VacuFlush toilet, vanity, sink and shower.

Updated Navigation and Electrical Systems

The helm has been upgraded with a Raymarine Axiom+ 9 RV multifunction display and Raymarine Ray53 VHF radio. A Raymarine RV-300 thru-hull transducer provides depth, bottom-imaging and fish-finding capabilities.

The electrical system has also been updated with a ProNautic 12-40P battery charger and four new AGM batteries.
