HH 66 Buyer's Guide
Shopping the brokerage market for an HH66 means entering the rarefied end of the carbon cruising catamaran world, where five examples have launched and each was built semi-custom in Xiamen, China. These are 66-foot boats with full-carbon construction, deep C-shaped daggerboards, and push-button sailhandling, typically run by a professional crew or a full-time captain. The used HH66s are individualized, so a buyer is choosing a specific owner's customization as much as a model.
Layouts on the Used Market
Charter four-cabin layouts are the more common on the used market, but both are available; ex-charter examples are common. The builder encourages customization in the accommodations plan and each boat's interior is laid out to the owner's tastes and demands, so beyond the dominant charter configuration a buyer should expect variation in stateroom finishing and salon arrangement. The Aft Helm version brings two helm stations aft for improved visibility and a larger salon, while the forward-helm SCF emphasizes line handling from the forward pit; either may appear among available boats.
Equipment and Common Upgrades
On the used fleet, watermakers, air conditioning, lithium batteries, asymmetric spinnakers, electric winches, chartplotters, code zeros, spinnakers, solar, inverters, radar, autopilots, life rafts, and often freezers, dinghy davits, cockpit showers, AIS, Starlink, and EPIRBs are fitted at varying tiers. The HH66's own design already supports a parallel diesel/electric hybrid with cabin-top solar and hydro-regeneration, and test boats have carried a couple dozen flexible solar panels; heating, hot water, swim platforms, and teak decks are less commonly seen and more likely owner upgrades. For the 66s, semi-custom carbon RIBs were an option against standard Highfield tenders, and the racing hardware package with upgraded winches appeared on at least one example.
What to Inspect
Documented known points center on the boat's systemic complexity rather than structural deficit. The HH66 has 19 strings in the forward cockpit, and push buttons in the armrest control all critical sailhandling and performance features including a panic button that immediately dumps and de-powers the mainsail and vang. The Ocean Data System's UpsideUp anti-capsize system monitors cap-shroud loads and automatically triggers an alarm, eases sheets or adjusts the autopilot, so its sensors and actuators deserve verification. Because the interior is configured per owner specification, survey a specific boat's systems routing and weight distribution — the forward locker with generator, hydraulics, and batteries is cited for ideal placement — rather than assuming a standard plan.
Availability and Buyer's Takeaway
Typical markets for the HH66 are the United States, Spain, Antigua and Barbuda, France, and China. With five built and no two alike, a buyer should:
- Confirm whether the layout is ex-charter four-cabin or another configuration
- Verify hybrid, solar, and battery systems against claimed offshore-living capacity
- Inspect push-button sailhandling, daggerboard controls, and anti-capsize system function
- Budget for professional crew or full-time captain operation
- Expect owner-specific customization in accommodations and equipment tier
