2025 Hallberg-Rassy 340, 534 000 USD

Umami is an exceptionally well-equipped 2025 Hallberg-Rassy 340, offered for sale by her original owner. She was ordered new from Hallberg-Rassy and built to his demanding specifications with virtually every available factory option. Not content with an already extensive factory specification, her owner went further after delivery, adding additional lithium battery capacity, a high-output alternator, a watermaker, and other upgrades to create a remarkably capable and self-sufficient 34-foot cruising yacht.

Her electrical and energy systems are a particular highlight. Umami carries a substantial 920 Ah Mastervolt lithium service bank supported by approximately 200 watts of solar generation and an ARCO Zeus 220-amp high-output alternator. A Mastervolt 3,000-watt inverter/charger supplies AC power aboard, and the system has sufficient capacity to operate the Dometic air conditioning overnight from the batteries without running a generator. Combined with her Spectra Ventura watermaker, this gives Umami an unusual degree of independence from shore power and marina facilities for a yacht of her size.

The cruising specification continues with Dometic air conditioning serving the saloon and forward cabin, Webasto diesel heating, a retractable 6 hp bow thruster, water-cooled refrigeration, and a well-equipped galley. Below deck she has Hallberg-Rassy’s two-cabin, one-head arrangement finished in European oak, with double berths forward and aft, a separate shower area, and additional sleeping accommodations available in the saloon.

Sail handling was specified for easy operation from the cockpit, with Seldén in-mast furling, electric Seldén Furlex headsail furling, upgraded Lewmar winches, and a Code Zero with complete handling equipment. Most of the running rigging was renewed in 2026, and Hallberg-Rassy completed a factory rig inspection the same year.

Her navigation package is equally comprehensive, centered around twin Raymarine Axiom Pro 9 multifunction displays with Quantum 2 Doppler radar, Raymarine autopilot, multiple i70s instruments, AIS700 Class B AIS, and Ray73 VHF. Twin steering wheels, twin rudders, Hallberg-Rassy’s permanent windscreen, a sprayhood, a teak cockpit, and a fold-out bathing platform complete the deck and cockpit arrangement.

Umami is powered by a Volvo Penta D1-30 29 hp diesel with saildrive and a folding bronze propeller. The engine has been Volvo dealer serviced with a full service history and received a new raw-water pump in 2026.

Importantly, Umami has continued to receive Hallberg-Rassy factory after-sales attention since delivery rather than simply leaving the factory and disappearing into private ownership. Her specification reflects an owner who knew what he wanted when the boat was built and continued improving her afterward.

Umami is now offered for sale because her owner has decided to move up to a larger yacht. For a buyer considering a Hallberg-Rassy 340, she presents an opportunity to acquire a late-model, one-owner boat with an unusually comprehensive factory specification and significant additional equipment already installed.
