Nautique Super Air G23 for Sale

Nautique Super Air G23 Specifications

The G23’s specifications tell the story of a boat built around a single obsession: producing the best possible wake and wave. At approximately 5,500 lbs dry, the hull is purpose-built to support up to 4,250 lbs of integrated ballast — meaning the boat can nearly double its displacement in riding configuration. Add 65 gallons of fuel and 17 passengers, and the G23 can weigh well over 12,000 lbs on the water. This mass is not incidental; it is the foundation of the wave. The PCM/GM 6.2L V8 in either the 409 HP standard or 450 HP optional configuration provides the torque necessary to keep this mass on plane and maintain precise speed control under varying load conditions.

The direct-drive inboard configuration is a deliberate engineering choice. Unlike V-drive towboats that place the engine forward and redirect the driveshaft to a transom-mounted propeller, the G23’s direct-drive layout positions the engine amidships with a straight shaft to the prop. This configuration adds weight in the optimal location for wake generation, reduces drivetrain complexity, and places the propeller deeper in the water column for improved thrust when the boat is loaded. The 12-degree transom deadrise provides the flat running surface needed for wake generation while maintaining enough hull entry angle to manage chop when repositioning between sets.

Wake & Surf Performance

NCRS (Nautique Configurable Running Surface): This is the technology that separates the G23 from every other towboat on the market. The NCRS is a patented system that allows the driver to adjust the hull’s running surface geometry while the boat is underway. Retractable hull plates alter the hydrodynamic profile of the bottom of the boat, changing how water flows beneath the hull and into the wake zone. In practical terms, this means the G23 can produce fundamentally different wake and wave shapes from the same hull — something that competing boats cannot do without physically modifying the hull. The NCRS is controlled from the LINC Panoray touchscreen at the helm, and adjustments take effect in real time. This technology was developed in-house by Nautique’s engineering team and is the result of years of computational fluid dynamics modelling, tank testing, and on-water validation with professional riders.

NSS (Nautique Surf System): Working in concert with the NCRS, the Nautique Surf System provides the wave-shaping layer that transforms raw displacement into a rideable surf wave. The NSS uses deployable tabs and integrated ballast management to control wave height, wave length, wave steepness, and the push behind the wave face. The system allows seamless transition from the port to the starboard surf wave without stopping the boat — the driver simply adjusts the NSS from the helm, and the wave transfers cleanly from one side to the other. This is a key differentiator for families with both regular and goofy-footed riders: no stopping, no waiting, no breaking the flow of a session. The NSS also enables fine-tuned wave shaping for different rider skill levels — a smaller, gentler wave for beginners and a tall, steep, powerful wave for advanced surfers.

Wave quality: The G23 is widely regarded as producing one of the best surf waves in the towboat industry. At surf speed (10–11.5 mph), the wave is clean, long, and powerful, with a gradual face that advanced surfers describe as “endlessly surfable” — a wave that rewards flow-style riding, allows sustained carving, and provides enough push for aerial manoeuvres. The wave is remarkably clean at the lip, with minimal whitewater or turbulence that plagues boats with poorly integrated ballast systems. This wave cleanliness is a direct result of the NCRS and NSS working together: the hull shape is optimised, the ballast is positioned precisely, and the wave-shaping tabs fine-tune the final product.

Wakeboard wake: At wakeboard speed (19–23 mph), the G23 produces a firm, well-defined, symmetrical wake that holds its shape from the boat out to 80–90 feet — the range where competitive riders set their rope length. The wake is consistent, predictable, and repeatable from pass to pass, which is why the Super Air Nautique platform is the official towboat of major wakeboard and wakesurf competitions worldwide. Professional riders including Shaun Murray, Parks Bonifay, and Dallas Friday have trained and competed behind Nautique boats throughout their careers.

Ballast system: The G23’s integrated ballast system distributes approximately 4,250 lbs of water across dedicated hard tanks positioned in the bow, midship, and stern. The tanks are engineered into the hull structure — not aftermarket bags stuffed into lockers — with optimised plumbing, high-flow pumps, and rapid fill times. The entire ballast system is controlled from the LINC Panoray touchscreen, where the driver can fill, drain, and adjust individual tank levels independently to fine-tune the wave shape. The integration of hull-engineered ballast with the NCRS and NSS is what gives the G23 its defining advantage: the hull, the weight, and the wave-shaping technology all work as a single coordinated system rather than as independent bolt-on components.

Engine Options & Drivetrain

The G23 is powered by PCM (Pleasurecraft Marine Engines) powerplants based on the General Motors 6.2L V8 block — a platform that is among the most proven and reliable in the marine industry. The standard 409 HP engine provides adequate performance for recreational use, but the optional 450 HP variant is the preferred choice for serious riders who regularly run at full ballast with a large crew. The additional horsepower and torque ensure strong acceleration when pulling a downed rider out of the water and maintain precise speed control when the boat is displacing 12,000+ lbs in riding configuration.

The PCM engines benefit from the same GM parts supply chain that supports millions of vehicles worldwide, keeping maintenance and replacement parts affordable and readily available. Annual service is straightforward: oil and filter changes every 50–100 hours, raw water impeller replacement, belt inspection, and coolant service. These engines routinely reach 1,000–2,000 hours with proper maintenance — and given that a typical towboat owner accumulates 100–200 hours per season, the powertrain will outlast most ownership cycles. The direct-drive configuration eliminates the complexity and maintenance overhead of a V-drive gearbox, with the trade-off being slightly less cockpit volume due to the engine box position.

Fuel consumption at surf speed (10–11.5 mph) is approximately 5–8 gallons per hour depending on ballast load, and at wakeboard speed (19–23 mph) is approximately 8–12 gallons per hour. The 65-gallon fuel tank provides a full day of riding for most families — approximately 6–10 hours of active towing before needing to refuel. GPS-based speed control is integrated into the LINC Panoray system, holding speed within a fraction of a mph regardless of load changes — a critical feature for consistent pulls.

Interior, Layout & Tower

Cockpit design: The G23’s interior is designed for the reality of a watersports day: wet riders rotating in and out, gear stacked in every available space, and a driver who needs clear sightlines to the rider behind the boat. The cockpit runs deep with high gunwales that keep spray out and provide a secure feeling for passengers. Nautique’s fit and finish is exceptional — panel gaps are tight, gelcoat quality is outstanding, and the upholstery materials reflect Correct Craft’s commitment to building the best towboat in the world. The NMMA-rated 17-person capacity is genuine — the G23’s cockpit comfortably accommodates a large group, which matters during long summer days on the lake with riders, spotters, and spectators.

Seating and bow: The wraparound cockpit seating features convertible rear benches that flip to create rear-facing positions for spotters and spectators watching the rider. The bow area provides generous lounge seating with filler cushions, integrated cup holders, and grab handles. All upholstery is marine-grade vinyl with UV-resistant treatments and antimicrobial properties — essential for a boat that lives in direct sunlight for most of its operational life. The driver’s position features a bolstered bucket seat with clear sightlines to the LINC Panoray display and to the tower mirror for rider observation.

Tower and accessories: The standard G-Series folding tower provides board racks, a high tow point for wakeboarding, and mounting positions for speakers and lights. The tower folds forward for garage clearance and trailering — a practical necessity for the majority of G23 owners who trailer their boats. The optional Razor electric tower adds powered height adjustment and a premium aesthetic with clean, angular lines. Tower speakers are integrated into the tower arms, and the standard JL Audio Marine system delivers clean, powerful audio that carries to the rider at rope length. Nautique’s tower engineering is robust, with oversized mounting hardware and corrosion-resistant construction that withstands years of freshwater and occasional saltwater exposure.

Helm and electronics: The LINC Panoray is Nautique’s proprietary 12-inch touchscreen that controls virtually every system on the boat: ballast fill/drain, NCRS position, NSS configuration, speed control, audio, lighting, and engine data. The interface is clean, responsive, and well-designed — Nautique has invested heavily in software development, and the Panoray system is widely regarded as the best helm display in the towboat industry. Rider profiles can be saved, storing each rider’s preferred speed, ballast configuration, NCRS setting, and NSS position for instant recall.

Storage: The G23 provides purpose-built storage for watersports equipment: a full-length in-floor ski locker accommodates wakeboards, surfboards, and skis; gunwale storage along both sides holds ropes, handles, and vests; the transom compartment provides engine access and additional gear storage; and the bow locker handles fenders, lines, and an anchor. The full-width swim platform at the transom features a non-skid surface, integrated boarding ladder, and a low-profile design that makes water entry and exit between sets effortless.

Nautique G23 Ownership & Running Costs

The Super Air Nautique G23 sits at the top of the premium towboat market, with new pricing that reflects its flagship status and the engineering sophistication of the NCRS and NSS systems. Ownership costs are predictable and manageable relative to the purchase price — a single inboard engine, no saildrives, no rigging, and no bottom paint if the boat is trailered. The principal costs are as follows:

• New pricing: A new Nautique Super Air G23 starts at approximately $180,000, but the majority of buyers configure the boat with options that push the final price to $220,000–$250,000+. Common upgrades include the 450 HP engine, the Razor electric tower, JL Audio premium sound, upgraded upholstery, custom gelcoat colours, and various electronics and lighting packages. Fully loaded G23s with every available option can exceed $280,000.
• Insurance: Watersports towboats carry a moderate premium over general recreational boats due to the towing activity. Expect 1.5–2.5% of hull value annually — on a boat insured at $200,000, that translates to $3,000–$5,000 per year. Agreed-value policies are strongly recommended, as the G23 holds its value well and a stated-value policy may underinsure you.
• Engine service (PCM): The PCM 6.2L V8 is a marinised GM LS-based engine with excellent reliability and a deep parts supply chain. Annual service (oil change, impeller, belts, fluid check) runs $400–$800 at a dealer, or $200–$400 for DIY owners. The 100-hour service is more comprehensive at $800–$1,500. PCM engines routinely reach 1,000–2,000+ hours with proper maintenance.
• Winterisation: Essential in northern climates. Professional winterisation including engine fogging, coolant flush, ballast system purge, and fuel stabilisation costs $400–$800. Shrink-wrapping adds $300–$600. Indoor heated storage costs $1,500–$3,500 for the season but provides superior protection.
• Trailer and towing: Most G23 owners trailer their boats. A tandem-axle trailer costs $4,000–$8,000 new. The combined towing weight of G23 plus trailer is approximately 8,000–9,000 lbs, requiring a full-size pickup truck or heavy-duty SUV. Annual trailer maintenance (bearings, brakes, tyres) adds $300–$600.
• Approximate total: $6,000–$14,000 per year for a trailered boat depending on usage and region. Slip-kept boats at premium lake marinas trend higher at $10,000–$18,000+ annually.

The Nautique dealer network provides strong service coverage across North America, with authorised dealers staffed by factory-trained technicians. Correct Craft’s Orlando facility maintains a comprehensive parts inventory for hull-specific components — upholstery, tower parts, NCRS and NSS components, and electronics are all available direct from the manufacturer. The G23 holds its value exceptionally well: a well-maintained G23 with moderate hours typically retains 70–80% of its original MSRP after three to four years, outperforming most other recreational boat segments.

Value Retention & Buying Guide

Used pricing: The used G23 market is active but supply-constrained — owners tend to keep these boats, and demand consistently outpaces supply. A 2020–2021 G23 with 200–400 engine hours typically asks $155,000–$185,000 depending on engine option and specification level. A 2022–2023 model with low hours asks $175,000–$215,000. Higher-hour boats (500+) trade at a discount, though engine hours on a PCM 6.2L are less concerning than on many platforms — these engines are designed for sustained use. The sweet spot for value is a 2021–2022 model with the 450 HP engine and a strong options package.

The Nautique lineup: The G23 sits within the Super Air Nautique G-Series range that includes the G21 (21 ft), G23, G25 (25 ft), and the flagship GS24 and GS22 models. Buyers considering the G23 should evaluate the G21 (smaller crew, tighter budget, similar wave quality in a more compact package) and the G25 (more ballast, more seating, larger wave, and a price tag $30,000–$50,000 above the G23). For most families and serious rider groups, the G23 represents the optimal balance of wave performance, crew capacity, and overall value in the Super Air Nautique range.

What to Inspect on a Used G23

• Engine hours and service records: Confirm regular oil changes (every 50–100 hours), impeller replacement, and coolant service. Ask for dealer service records. A compression test on engines over 500 hours provides peace of mind. The PCM 6.2L is a robust engine, but maintenance history is non-negotiable.
• NCRS and NSS system: Run the NCRS through its full range of adjustment and verify smooth, responsive operation. Test the NSS wave-shaping tabs on both port and starboard sides. These are the technologies that define the G23 experience, and any malfunction should be resolved before purchase.
• Ballast system: Run every ballast pump through a complete fill-and-drain cycle. Listen for pump strain, check for leaks at fittings and hose connections, and verify fill times are within specification. Ballast pump failure is the most common mechanical issue on used towboats.
• Tower and gelcoat: Inspect tower base mounts for corrosion or stress cracks. Check the folding mechanism. Examine gelcoat for spider cracks, particularly around the tower mounting points and at the waterline. UV damage to upholstery is the primary cosmetic concern — a boat that has been covered or stored indoors will show dramatically less wear.
• LINC Panoray system: Power up the display and test every function: ballast controls, NCRS, NSS, speed control, audio, and lighting. The touchscreen should be responsive and free of dead spots. Software updates may be available from Nautique for older firmware versions.

Nautique’s status as a privately held, family-guided company within the Correct Craft organisation means the brand is not subject to the short-term earnings pressures that can affect publicly traded competitors. Correct Craft’s stated mission — “Making Life Better” — extends to a corporate culture that prioritises long-term build quality over quarterly production targets. For buyers, this translates to a boat that is built with genuine care, backed by a manufacturer with a century of history, and supported by a dealer network that treats ownership as a relationship rather than a transaction.

Nautique Super Air G23 vs Competitors

The 23-foot premium towboat segment is the most competitive space in the watersports boat market, dominated by a small group of American manufacturers that have spent decades refining their hull designs, ballast systems, and wave-shaping technology. The Nautique G23 competes at the very top of this segment, where the NCRS and NSS give it a technological edge that competitors have been unable to fully replicate. Every serious towboat buyer should ride behind each of these boats before committing — wave preference is personal, and what suits one rider may not suit another.

Nautique G23 vs MasterCraft X24

This is the defining rivalry of the premium towboat market. The MasterCraft X24 uses the Gen 2 SurfStar system with integrated ballast and wave-shaping tabs; the Nautique G23 uses the NCRS and NSS. Both produce world-class waves and wakes. The fundamental difference is the NCRS — Nautique’s ability to alter the hull’s running surface geometry gives the G23 an additional dimension of adjustability that the X24 cannot match. The G23’s wave tends to be longer and more gradual, which many surfers prefer for flow-style riding. The X24 tends to produce a slightly more aggressive, peaky wave that some advanced riders favour for power turns and aerials. Build quality on both boats is outstanding. MasterCraft trades publicly (NASDAQ: MCFT) and builds in Vonore, Tennessee; Nautique is privately held and builds in Orlando, Florida. Pricing and resale values are comparable. The deciding factor should be a back-to-back demo day behind both boats.

Nautique G23 vs Malibu 23 MXZ

The Malibu 23 MXZ is the flagship of Malibu Boats (NASDAQ: MBUU), based in Loudon, Tennessee. The MXZ uses Malibu’s Surf Gate system — one of the original wave-shaping technologies, using deployable gates at the transom to redirect the wake. The Malibu produces an excellent surf wave, and the Surf Gate system is proven and well-refined over multiple generations. Where the G23 differentiates is in the NCRS technology, which provides a level of hull customisation that the Malibu’s fixed hull cannot match. Interior fit and finish on the G23 is generally considered a step above the Malibu in direct comparison. The MXZ counters with competitive pricing (typically $15,000–$25,000 less than an equivalently specified G23), the industry’s largest dealer network, and a strong owner community. For buyers who are price-sensitive but want premium wave quality, the MXZ deserves a serious test ride.

Nautique G23 vs Centurion Fi23

Centurion, a subsidiary of Fineline Industries in Burlington, Washington, has built a devoted following among riders who prioritise wave quality above all else. The Fi23 features the RAMFILL ballast system with industry-leading ballast capacity and the Opti-V hull, producing a wave that many advanced surfers rate as among the very best in the industry. The Centurion is the value-oriented disruptor in this segment — a smaller company that punches well above its weight in wave performance. The G23 counters with the NCRS technology (which Centurion cannot match), Correct Craft’s century-old brand heritage, stronger resale values, and a broader dealer network. The Centurion typically prices $20,000–$35,000 below an equivalently specified G23. For riders who chase maximum wave size and are less concerned with brand prestige and resale, the Fi23 is worth a demo.

Nautique G23 vs Tige 23 RZX

Tige, based in Abilene, Texas, occupies a distinctive position with an emphasis on customisation and aggressive styling. The 23 RZX uses the TAPS 3T (Tige Adjustable Pitch System) surf platform, delivering precise wave tuning from the helm. The Tige produces a strong surf wave and a solid wakeboard wake, and the TAPS system is intuitive and effective. Interior styling is bolder than the G23’s more refined aesthetic. Build quality is solid, though most industry reviewers place Tige a half-step behind Nautique and MasterCraft in overall fit and finish. Tige prices $15,000–$30,000 below an equivalent G23, and the company offers extensive customisation options. Resale values are good but do not match Nautique at the top of the segment. The Tige appeals to buyers who want strong wave performance with a distinctive visual identity at a more accessible price point.
