Chaparral 300 OSX Boats For Sale

The Chaparral 300 OSX is an outboard-powered day cruiser in the 30-foot range that combines the open layout of a center console with the family seating of a dual console, plus a below-deck cabin. It carries an overall length of 29 feet 6 inches (listed as 30 feet 6 inches LOA by the builder), a beam of 9 feet 6 inches, and a 170-gallon fuel capacity. The hull uses a Kevlar-reinforced bottom, a poured composite transom, and a self-bailing cockpit, with cockpit drains routed directly overboard rather than into the bilge. This is the boat for a buyer who wants center-console handling without giving up bow lounging and overnight space.

Performance comes from twin outboards, commonly twin Yamaha F300 four-strokes, though Mercury 350 power has also been fitted. With twin F300s and a test weight near 10,715 pounds, the Chaparral boats 300 OSX reached a top speed of 57 mph at 6,000 rpm. Best cruising economy landed at 3,500 rpm and 33 mph, where a 17.8 gph burn returned 1.9 mpg and a range of about 284 statute miles while holding a 10% fuel reserve. At 5,000 rpm the boat ran 49 mph at 36.3 gph, and at 650 rpm idle it made 3.5 mph at 2.9 mpg. Steering is by SeaStar/Optimus 360 power steering with a joystick, and Yamaha Helm Master with autopilot is available depending on engine package.

The defining feature is the center-steer helm, placing the driver dead center on a symmetrical, leather-wrapped dash. Standard electronics include twin Simrad displays (9-inch and 10-inch units appear across builds) flanking a central engine gauge, with backlit push-button switches on stainless panels, a tilting hydraulic wheel, and binnacle throttles to starboard at roughly a 45-degree angle. Lenco trim tab controls are mounted vertically beside the wheel, and a Clarion stereo, dual USB and 12-volt outlets, and cell phone charging sit at the helm. Forward visibility is strong, with 21 inches of open sightline between the windshield and the standing-headroom hardtop.

Shade and weather protection center on the standard fiberglass hardtop, built on a powder-coated heavy-duty aluminum frame with overhead LED lighting, two speaker pods, and a bonded glass skylight with a dual shade system. The optional Sure Shade (silent glider) retractable canopy extends coverage aft toward the swim platform. Owners shopping for Chaparral 300 OSX T-top boat canvas or a Chaparral 300 OSX T-top boat cover will be matching to this hardtop and its powder-coated frame rather than a fabric tower.

Deck layout is built around entertaining. The triple-wide helm seat pivots on a fiberglass base to swing against the starboard wall and open the cockpit, while the aft Vista View lounge converts by push-button into a flat queen-size sun pad, an aft-facing chaise, or a forward-facing lounge. The bow holds a forward-facing sun lounge wide enough for three adults, measuring 62 inches at the back and tapering to 53 inches forward, with wraparound bolsters, recessed JL Audio speakers, cup holders, and an optional filler cushion. A standard windlass with a 22-pound stainless anchor, a starboard dive door with aluminum ladder, a walk-through transom, and a full-width swim platform with dual fuel fills round out access.

Below deck, a sliding lockable door to starboard of the helm opens to a fiberglass cabin with a forward berth for two, an opening port light, overhead LED lighting, a vanity with solid-surface countertop and stainless sink, and a concealed electric toilet on a sliding mechanism. Seating headroom is about 3 feet 1 inch, and an optional 12-volt air conditioning system is available for the cabin. A wet bar option at the helm adds a solid-surface counter, refrigerator, stainless sink with sprayer, and hidden trash. Used examples of the Chaparral 300 boat from model years 2020 through 2024 turn up for sale; when comparing them, weigh engine brand and hours, whether AC and the Sure Shade canopy are fitted, and whether the boat has the pivoting helm seat or the stationary helm with wet bar.
