Voyage 510 Sailboat Review, Specs, and Listings

Variations & Configurations

The Voyage 510 features a standardized hull profile with a length overall (LOA) of 51' 10" (15.8 m), a beam of 26' 11" (8.2 m), and a draft of 4' 11" (1.5 m) dictated by its low-aspect fixed twin keels. Under the hood, standard propulsion consists of twin 57 HP Yanmar 4JH57 diesel engines connected to traditional shaft drives, bypassing the maintenance complexities of sail-drives in remote cruising areas.

Voyage Yachts offers two primary layout configurations that fundamentally alter the vessel's utility:

Charter Layout: This high-occupancy configuration provides four identically proportioned, en-suite queen staterooms. This layout is engineered to eliminate the "owner's cabin bias" typical of private yachts, making it ideal for bareboat or crewed charter programs. Additionally, the forward bow compartments in each hull are configured as single en-suite crew cabins, enabling the vessel to comfortably sleep up to 10 individuals.
Owner’s Layout: Tailored for long-range cruising couples, this version dedicates the entire starboard hull to a private master suite. This layout includes a queen berth aft, a midships private companionway lounge, a vanity/desk area, and a large forward en-suite head. In this configuration, the starboard bow compartment is repurposed as a dedicated utility room, which can be outfitted with laundry machines, a workshop, or deep storage.

Rigging configurations remain consistent, utilizing a Sparcraft 7/8th fractional anodized aluminum mast. It features an overlapping sail plan consisting of a 1,044 sq ft (97 m²) fully battened mainsail and a 592 sq ft (55 m²) overlapping genoa, delivering a total standard working sail area of 1,636 sq ft (152 m²).

Sailing Performance & Handling

The engineering profile of the Voyage 510 is defined by its calculated design ratios, which dictate how the 42,990-pound vessel behaves under sail.

Sail Area to Displacement (SA/Disp) Ratio of 22.03: This indicates a high-performance capability relative to typical cruising multihulls, which often hover in the 15 to 18 range. This high ratio means the 510 carries sufficient sail power to stay agile and responsive in light-air conditions, accelerating out of tacks without immediately requiring specialized downwind sails.
Displacement to Waterline Length (Disp/LWL) Ratio of 140.43: Reflecting a relatively light-to-medium displacement profile on a long 51' 6" waterline, this ratio highlights efficient hull dynamics. The hulls have slender entry lines that minimize wave-making resistance, allowing the boat to glide smoothly over chop rather than hobby-horsing or slamming into head seas.
Comfort Ratio of 16.08 and Capsize Screening Ratio of 3.07: While traditional comfort formulas favor heavy, deep-keeled monohulls, a score of 16.08 on a multihull of this size indicates a highly predictable and gentle motion profile. The capsize screening value of 3.07 reflects the immense form stability generated by the boat's 26' 11" beam. The boat resists rolling entirely, instead translating wave action into quick, low-amplitude movements.

At the helm, the 510 is highly centralized. A raised starboard helm station consolidates all essential lines—including sheets, halyards, traveler controls, and windlass remotes—to electric winches. During real-world trials conducted in Cape Town under conditions ranging from flat calm to 38-knot squalls, the 510 demonstrated exceptional directional tracking. Upwind, the hulls grip the water with minimal leeway, holding course without heavy loads transferring to the wheel. Off the wind, the boat slips into a stable, dry reach, benefiting from high freeboards that deflect spray away from both the aft and forward cockpits.

Market Snapshot & Economics

With a median price of $1,412,178.60 and an active listing count of 3, the Voyage 510 occupies a premium, low-volume niche in the brokerage and new-build markets.

Several factors govern the economics of this model:

Tightly Controlled Production: Built in South Africa, the Voyage 510 is not mass-produced. The builder’s close integration with Voyage Charters in the British Virgin Islands means a significant percentage of initial hulls go straight into managed charter programs, keeping public brokerage availability extremely low.
Charter Management Integration: For buyers placing the 510 into a charter fleet, the model's standardized en-suite layout makes it a highly competitive asset. High charter demand in premium destinations like Tortola helps offset the high initial capital expenditure, covering dockage, insurance, and routine mechanical maintenance.
New-Build Premium: Because the production run began in 2025, any available vessels are practically new. The median price reflects highly optioned, turn-key vessels outfitted with generator systems, watermakers, and high-capacity climate control. This insulates buyers from the immediate, costly refit cycles associated with older vessels.

Modernization & Upgrades

The Voyage 510 represents a modern build era where traditional, heavy AC-generation systems are increasingly complemented or replaced by highly efficient DC systems. Key customization and upgrade pathways for the 510 include:

Solar Array Integration: The factory hardtop and flybridge structure are designed to be solar-ready. Owners looking to maximize off-grid capability frequently cover these structures with high-efficiency rigid solar panels, feeding into a consolidated MPPT controller network to keep the house banks topped up without generator intervention.
Advanced Lithium (LiFePO4) Power Banks: Standard builds feature a heavy-duty Victron-managed 24V house bank (typically 600Ah / 14.4kWh). Upgrading this system to larger lithium-iron-phosphate (LiFePO4) banks allows owners to run high-draw onboard systems—such as the domestic air conditioning, watermaker, and dive compressors—directly off the inverter overnight, eliminating generator noise.
Propulsion Upgrades: While standard propulsion relies on Yanmar diesels, the engine compartments are unusually spacious, designed specifically to accommodate future power trends. Voyage Yachts has actively pioneered hybrid-electric propulsion on prior models, and the 510 platform is engineered to support high-voltage (48V or 144V) electric drives with hydro-generation capabilities for silent motoring and self-sustaining energy capture under sail.
Galley Efficiency: Rather than old-school AC-powered "cold plate" systems, the 510 utilizes dedicated high-efficiency 24V DC drawer refrigeration systems (typically three refrigerator drawers and two freezer drawers). This reduces the continuous load on the inverter and simplifies long-range food storage.

The Verdict

The Voyage 510 is a masterfully engineered, premium cruising catamaran that successfully bridges the gap between rugged, blue-water capability and high-density luxury chartering. It is not a budget-oriented mass-production multihull, but rather a specialized, high-integrity cruiser built to survive the demanding waters of both the South African coast and intensive Caribbean charter seasons.

Pros

Superior South African Build Quality: Utilizes vacuum-infused polyester resin with quad-axial glass fabric and closed-cell PVC cores, resulting in an exceptionally stiff, lightweight, and durable structure.
Excellent Sailing Dynamics: A high SA/Disp of 22.03 and an efficient hull form ensure the boat remains fast, responsive, and dry across a wide range of wind angles and wind speeds.
Engineered Serviceability: Features an easily accessible, oversized engine room and clean layout of major plumbing and electrical systems.
Centralized Helm Control: Elevated helm station with electronic controls for winches, sheets, and engines allows for secure, shorthanded sailing.
Flexible Accommodations: Equally viable as an uncompromised private owner's liveaboard or a high-capacity, 10-berth charter machine.

Cons

High Capital Barrier: With a starting base price over $1.2M ex-tax (and median outfitted values surpassing $1.4M), it represents a significant financial investment.
Scarcity on the Market: Extremely low listing counts mean buyers face long wait times for new builds or must compete heavily for rare brokerage entries.
Substantial Windage: The high freeboards and multi-level deck structures (flybridge and hardtop) create significant windage, requiring confident handling and active use of the twin engines when maneuvering in tight marinas during high crosswinds.
