Explore one of the most sustainable yachts on the water today
This month, Spirit Yachts unveiled its highly anticipated 34m sailing yacht, the Spirit 111. With eco features throughout and a stand-out interior design, the sloop-rigged yacht is the largest single-masted wooden sailing yacht to be built in the UK since Shamrock V in the 1930s.
At the request of her overseas buyer, the Spirit 111 has been designed and built in-house by Spirit Yachts to be one of the most environmentally friendly sailing superyachts ever created.
Spirit Yachts managing director Nigel Stuart commented, “Showcasing the Spirit 111 under sail and revealing her unique interior is a real milestone for the company. The yacht is incredibly complex in her design and engineering and we are very proud of what we have delivered. It’s been a challenging journey, which has given us the opportunity to innovate and gain insight for future superyacht and eco-focused builds.”
Spirit Yachts 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 30nm at eight knots 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.
Nigel Stuart explained: “It is important to the owner that he can spend the majority of his time away from marinas enjoying sailing and anchoring in bays. 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.”
Nigel continued: “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. 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 materials that can be recycled are fitted to a Hall Spars carbon fibre mast and in-boom furling to facilitate short-handed sailing.
Spirit founder and head designer Sean McMillan commented: “A single-masted wooden yacht of this size that can be owner-driven is nothing less than a feat of engineering. The yacht’s impressive strength to weight ratio, a carbon rig and lightweight, performance sails will allow the owner to compete at regattas worldwide.”
The interior of the Spirit 111 was designed in partnership with Rhoades Young, which is Spirit Yachts’ first collaboration with an external design agency. Rhoades Young developed the initial concept for a unique, curved interior, which Spirit Yachts’ design team developed and brought to life in the final plans.

Rhoades Young partner Jonathan Rhoades commented: “It was a joy to work with a client with an absolute passion for design. The brief was a combination of his love for furniture and organic architecture. The client had recently visited Antelope Canyon in Arizona and this was the catalyst for the idea of the warm soft flowing walls creating unique focal points within the room. Whilst appearing simple these twisting forms are co-ordinated perfectly with the beautiful skylights above creating a calm and tranquil ambiance. These elegant forms not only twist and peel to create counters but uniquely create the intimate back drops for the highly detailed ‘steam pieces’ which blur the line between furniture and sculpture. It has been an absolute privilege to work on this project with the client and the craftsmen and women who created it.”

Spirit Yachts head designer Sean McMillan commented: “The Spirit 111 has been completely customised throughout and as a result her interior is totally unique. The design is a never-ending swirl of organic shapes, encompassing the practicalities necessary in a yacht but in a highly imaginative way.”
The Spirit 111 owner’s representative, Marcus Wright, added: “It was a great privilege to represent the owner’s interests and ensure we delivered a yacht that surpassed his expectations. With the knowledge that Spirit Yachts can make absolutely anything in wood, it was a thoroughly enjoyable process to take Rhoades Young’s beautiful interpretation of an unusual brief and assist in the creation of such a work of art.”
Down below, walls and bulkheads flow in an ‘S’ shape through the interior, which has a natural look and feel thanks to the combination of the exposed Sipo, teak and American Walnut timbers on show. A bespoke, curved American Walnut seating arrangement takes centre stage in the open plan saloon-galley and C-shaped arrangements created from steamed timber curve over the beds in the owner’s and VIP cabins. Discreet doors with hidden, sensor-activated recesses, rather than visible door handles, ensure smooth lines and a contoured look throughout.

The smart lighting system onboard will complement the soft warmth of the wooden interior. Spirit Yachts managing director Nigel Stuart explained: “The interior has almost no light switches; motion sensors turn lights on and off during the day. At night, sensors under the beds detect if someone is up and light the way to the nearest ensuite. If a guest starts to go elsewhere within the interior, the system will deduce which way they are going and light the relevant areas in a very soft warm light.”

With no requirements for crew accommodation, guests have the choice of two double ensuite aft cabins or a starboard side double VIP cabin. The forward cabin holds the spacious master suite, complete with curved sofas built into the side of the hull, double bed and ensuite. All heads have rounded, solid timber sinks integrated into the worktop and power showers.

2 x 25kW DC generators as a back up to power. These operate at the peak efficiency and preferred load only.
Batteries charge by regeneration whilst sailing, via the generator or by shore power.
Lewmar hydraulic system
The Lewmar hydraulic system uses a Vortex reservoir to reduce the amount of oil in the system by 90%. By reducing the amount of oil, the Vortex delivers a weight saving of 53% compared to a traditional power pack, and saves the amount of oil required for servicing, lessening the impact on the environment.
The hydraulic power comes from a high voltage Torqeedo motor, and as a backup, a smaller low voltage DC Lewmar power pack.
The system has three modes, so that when sailing in Eco mode the yacht uses minimal battery power. The other two modes are Fast Cruise and Race.
Sails by OneSails GBR (East)
OneSails GBR (East) has supplied a wardrobe of high performance 4T FORTE™ three dimensional sails including a mainsail, jib, staysail, FFR flat furling reacher and a furling asymmetric.
OneSails’ 4T FORTE™ sails are currently the only EU certified recyclable sails on the market.
Air conditioning and hot water generation by Webasto
Air conditioning and air heating is managed by two Webasto variable speed units. These have been designed to operate in the most power efficient manner with three modes: Eco1, Eco 2 and Max.
The air conditioning is so efficient that the generators are not required to run overnight even in the tropical climates.
Hot water is provided by a Webasto 5kW boiler or using the residual heat from the generators and stored in a high density insulated tank fitted with finned tubing for rapid heat transfer.
Both fridge and freezer are custom units using CryoGel insulation along with super-efficient compressors.
The bespoke American Walnut seating and bed heads for the Spirit 111 were built by Will Fennell and Ben Jackson; both former employees of Spirit Yachts, who have teamed up with the company on this landmark project.
Designed and developed by Spirit Yachts, the two-part seating arrangement was made out of strips of 10mm x 10mm American Walnut and took over 2,000 man-hours to build by hand.
