2023 HH Catamarans HH66

The 2023 HH66 is a full-carbon custom catamaran built to performance standards. At 66 feet with a 28.5-foot beam, she combines racing capability with comprehensive cruising equipment. Powered by a single 160-horsepower Yanmar diesel engine, the hull features epoxy-infused carbon construction with composite foam sandwich core, engineered to CE and ISO standards. The build incorporates bespoke upgrades throughout: ultra-high modulus carbon daggerboards with hydraulic rake and depth control, carbon T-foil rudders with 24V actuators, and a rotating carbon wing mast with Swiss carbon standing rigging. All primary systems—daggerboards, rudder, and rig controls—operate from both helm stations via a custom Cariboni hydraulic setup.

Four en-suite cabins provide accommodation with queen berths and 150mm foam mattresses. Interior joinery uses teak veneer carbon composite throughout. The galley features a Force 10 four-burner stove with oven, Vitrifrigo refrigeration, and a Webasto wine cooler and Isotherm ice maker. Saloon and all cabins have 44,000 BTU Dometic air conditioning. Switchable smart glass windows provide privacy without blinds. Ultraleather and Sunbrella furnishings are throughout, with LED lighting including underwater transoms and courtesy lights.

Navigation and connectivity include full Garmin Zeus electronics with 19-inch chart displays at each helm and nav station, Starlink satellite internet, and B&G integration at all stations. The 720 amp-hour lithium ion 24V battery bank runs via full Mastervolt management. A Spectra Newport 400c watermaker produces 61 liters per hour. A Rocna 55-kilogram primary anchor with Lewmar V5 electric windlass rounds out the seamanship setup.

The sail wardrobe is dual-purpose: a 2026 new Doyle mainsail in fresh membrane material, a 2021 North cruising mainsail cut to second reef, plus multiple jibs, code zero, and asymmetric spinnakers from North in both current and recent vintages. A full canvas package—cockpit awning, sail covers, wheel covers, window covers—is included.
