The UK’s Spirit Yachts has launched its new flagship 34m sailing yacht, the Spirit 111. Lowered into the water for the first time at Spirit’s waterside headquarters in Ipswich, Suffolk, the sloop-rigged yacht is said to be the largest single-masted wooden yacht to be built in the UK since Shamrock V in the 1930s.

At the request of its overseas buyer, the Spirit 111 was designed and built in-house to be one of the most environmentally friendly sailing superyachts ever created.

Spirit worked collaboratively with leading marine and automotive suppliers to deliver on the owner’s eco brief. A Torqeedo electric propulsion system using a 100kW motor will propel the yacht silently for up to 40Nm at 8kt from battery power alone. Whilst sailing, the propulsion system will regenerate the four BMW lithium battery banks by rotating the propeller shaft whilst the yacht is under sail. All power-consuming components have been carefully selected to be highly efficient and will use minimal energy without impacting performance or comfort.

“It is important to the owner that he can spend the majority of his time away from marinas enjoying sailing and anchoring in bays,” says Nigel Stuart, managing director of Spirit Yachts. “Using electric propulsion to regenerate the batteries whilst sailing, the yacht will be able to operate for up to four days at anchor without having to plug into shore power or start the two onboard generators. When the yacht crosses the Atlantic, as long as there is adequate wind, she will not need to consume any fossil fuels.

“By partnering with suppliers and challenging ourselves to create customised solutions using the latest energy-saving technology, we have created one of the world’s most sustainable superyachts,” he adds. “From construction using responsibly sourced timber to carbon-saving systems whilst in operation, the Spirit 111 sets a new standard for reducing the impact sailing has on our environment.”

The air conditioning uses variable speeds with eco options via battery or shore power and the galley has been designed with ultimate efficiency in mind. The fridge and freezer were built with Cryogel insulation to ensure minimal power consumption whilst holding low temperatures. Water is heated using a Webasto system, which only heats water on demand ensuring no wasted water or energy, and the heated water is stored within high density insulation and high efficiency transfer coils for rapid heat transfer and temperature retention.

The Spirit 111 is also one of few superyachts capable of cruising without professional crew. Energy efficient Lewmar hydraulic deck hardware and OneSails GBR (East) 4T Forte sails made from recyclable materials will be fitted to a Hall Spar carbon fibre mast and in-boom furling to facilitate short-handed sailing.
