2012 Rinker 310 Express Cruiser 31'

Some boats are built to cross oceans. 

Others are built to help you leave the workweek behind.

The 2012 Rinker Express Cruiser 310 was designed for couples and families who measure success not by how many miles they travel, but by how quickly they can trade conference calls for quiet anchorages. Forty-five minutes after leaving the office, you could be dropping the hook in your favorite cove, enjoying a cool cabin, a warm sunset, and the satisfaction of leaving the week’s deadlines on shore.

This exceptionally well-equipped example features the highly desirable factory hardtop, Axius joystick docking, reverse-cycle air conditioning, and a Kohler 5.0 kW generator professionally rebuilt in October 2024, providing the comfort and confidence to spend weekends away from the dock. Twin 300-horsepower MerCruiser 350 MAG MPI engines with Bravo III dual-prop sterndrives deliver responsive performance, comfortable cruising speeds, and excellent maneuverability whether you’re making a waterfront dinner reservation or anchoring for the night.

The expansive cockpit is clearly the social center of the boat, featuring wraparound seating that converts into a sun lounge, a fully equipped summer kitchen with refrigerator and electric grill, and excellent visibility from the double helm seat. Whether entertaining friends at the sandbar or enjoying a quiet evening at anchor, the layout encourages conversation as much as cruising.

Below deck, the warm Brazilwood cabinetry, Corian countertops, overhead skylight, and thoughtfully designed accommodations create an inviting retreat. A convertible salon, forward berth, private mid-cabin, full galley, and stand-up head comfortably accommodate four, making spontaneous weekend getaways as practical as they are enjoyable.

Performance is equally impressive. Cruise comfortably at approximately 28.5 MPH while burning just 20 to 22 gallons per hour combined, with a cruising range approaching 200 miles. An electric windlass, Garmin electronics, premium sound system, full camper canvas enclosure, and numerous thoughtful amenities complete a package that is equally at home entertaining at the dock or escaping for an extended weekend on the water.

If you’ve been looking for a well-equipped express cruiser that combines performance, comfort, and effortless weekend cruising, this Rinker 310 deserves your attention.
