Boat Features

The Sea Ray 300 Sundancer is a twin-engine sport cruiser built as a true weekender for couples and small families. Despite the model name, the hull measures 33 feet 4 inches in overall length with a 10-foot 5-inch beam, and one example carries a dry weight of 12,500 pounds. Sea Ray 300 Sundancer specifications include a 170-gallon fuel capacity and a 40-gallon fresh water tank, which support multi-day cruising. The profile carries heavy-duty stainless rails, a beach-to-bow ladder, and a deep cockpit, and the cabin feels unusually large for a 30-foot boat.

Power varied across the production run, which matters when comparing Sea Ray 300 Sundancer specs between model years. A 1987 Sea Ray 300 Sundancer was fitted with twin 350 MerCruisers on Alpha One drives, while later boats moved to sterndrives such as twin 5.0 MPI MerCruisers on Bravo 3 outdrives, twin 6.2-liter MerCruiser V8s, and twin 350 Mag MerCruisers, also on Bravo 3 drives. The Bravo 3 setups use dual stainless propellers, and trim tabs come standard for adjusting running attitude. Engine hours on well-kept examples can be very low, with one boat showing 75 hours on the port engine and 57 on the starboard, and another reading 390 hours.

The single-level cockpit steps up to a helm equipped with a full gauge cluster, blower and bilge switches, and ignition switches mounted below the wheel that you flip and push in to start. Navigation electronics range from a basic Garmin chart plotter on early boats to factory chart plotters with VHF radio, with some boats updated to a Humminbird Helix 5. Other helm features include a hydraulic lift engine hatch, an electric windlass with a Fortress anchor and chain, a forward actuating windshield vent, a spotlight on the bow, and a Clarion stereo with a six-disc CD changer.

The cockpit seats a crew on a triple-wide or two-person helm bench with flip-up bolsters, plus an aft bench that folds away and a rear table that drops to form a sunpad or berth. A center pullout tray doubles as a cooler, and a wet bar with sink and a cockpit refrigerator sit aft. The transom includes a walk-through door to a large swim platform, and rod holders flank the cockpit. Options seen on these boats include a custom stainless bait board and barbecue, a full camper canvas enclosure with isinglass and zip-out screens, and SeaDek cockpit flooring.

The Sea Ray 300 Sundancer interior is finished in Cherrywood with a forward berth for two, a convertible dinette that drops into a second bed, and a mid-cabin berth aft of the companionway. The galley to port carries a Norcold refrigerator or fridge/freezer, a two-burner electric cooktop, a microwave, and a stainless sink with hot and cold water. The full stand-up head has a VacuFlush toilet, a medicine cabinet, storage, and a sink faucet that doubles as the shower head. Air conditioning and heat were available, along with a TV and DVD player.

When shopping a Sea Ray 300 Sundancer for sale, check the generator: examples were offered with onboard Westerbeke or similar gensets, but some have had the unit removed, and the earliest boats shipped without one. Owners report solid fiberglass with no blistering or soft spots on well-maintained hulls. Boats turn up both through brokers and as a Sea Ray 300 Sundancer for sale by owner, with motivated private sellers affecting the asking price.
