Cobalt CS23 Boats For Sale

The Cobalt CS23 is a 23-foot bowrider that brings the brand's premium fit and finish into a smaller, more easily trailerable package than the larger R series, at a lower price point. It measures 23 feet 5 inches length overall with an 8-foot-6 beam and carries a 60-gallon fuel tank, and it is rated for 12 persons. The hull uses a deep-V forward section with multiple strakes for a clean entry in light chop, and the floor is lowered to gain interior depth, so even with moderate freeboard the cockpit and bow sit deep. A continuous stainless rub rail and shoebox deck-to-hull fit allow an integrated full-beam swim platform without a bolted-on extension. Buyers can personalize the exterior with one of 12 gelcoat colors across the hull side, boot stripe, and hull bottom.

Power on most CS23 examples is the Volvo Penta 280-horsepower 4.3-liter V6 with a Duoprop dual-prop drive, an aluminum-block, aluminum-head, closed-cooling engine that delivers more torque and thrust than the single-prop drives common in this size class; one example is fitted with a 300-horsepower V8 and the dual prop. Engine choices include Volvo Penta and MerCruiser, and a new drive-by-wire Monsoon package built by Malibu paired with a MerCruiser outdrive joins the lineup with its own control. All control systems add cruise control and power trim assist. The engine compartment lifts on two stainless gas-assist struts, is fully composite and insulated, and houses both batteries amidships for balanced weight and easy access.

The helm carries a fully upholstered dash with hand-stitched leather, a tilt three-spoke steering wheel, and digitally driven analog-style gauges with LCD screens as standard; optional setups add a single Garmin 7-inch touchscreen or a center gauge cluster with a lower Garmin display. A wireless phone charger and XM Weather with Garmin are available, and the obsidian windshield uses slightly curved glass in a black frame with the brand's solid stainless steel braces for a rigid, rattle-free mount. The squared-off windshield design adds interior volume rather than curving into the boat. Audio runs from a standard six-speaker package up to a premium 1,800-watt system or the Harman Kardon platinum package with up to 2,400 watts tuned to the boat.

The transom area includes a flip-down swim step, a lean-back transom cushion for sitting with feet in the water, and an optional rumble seat. A built-in cooler and trash receptacle sit on the port side, and the aft walk-through holds deep storage large enough for water skis. Inside, the cockpit spans the full 8-foot-6 beam with wraparound coaming, a flip-flop port passenger backrest with forward-facing and aft-facing lounge positions, and 16 stainless drink holders kept low and out of the wind alongside USB-A, USB-C, and 12-volt ports. Four interior colors are offered — summit/frost, frost/slate, caramel, and summit/cocoa — with darker fresco chill vinyls that run 15 degrees cooler in the sun, plus a choice of Sof-Trac mat or snap-in seagrass flooring.

The bow is deep and wide for a 23-footer, with thick wraparound padding, stainless grab rails, low cup holders, a removable cushion, one-piece flip-up seats over large storage, and a dedicated anchor locker; an optional bow filler and bow shade sail extend its use. A walkthrough windshield blockoff door stows flush. A CS23 Surf variant builds on the same hull with 1,244 pounds of ballast, the Malibu-patented Surf Gate, a forward-facing drive, dual Garmin 7-inch displays with savable rider profiles, and a Zenith aluminum folding arch with Roswell board racks. Cobalt CS23 boats for sale are commonly paired with a custom Cobalt Heritage trailer and a folding wake tower with bimini.
