Spirit Yachts has begun constructing a 13.4m electric yacht, the Spirit 44E, for an eco-minded overseas buyer. Due to launch in early 2020, it’s the firm’s first electric yacht.
Spirit Yachts head designer Sean McMillan commented, “From afar, the Spirit 44E will look like any other Spirit sailing yacht. Low freeboards, long overhangs, flush decks and the timeless beauty of quality wooden craftsmanship. Up close, she will display signs of the sailing yachts of the future.”
Two solar panels will be integrated into the aft deck and will colour match the teak, so they blend with the deck both in aesthetics and alignment. The panels will charge OceanVolt 48VDC 30.4kWh batteries (made up of 48 1.9kWh batteries), which will power her Oceanvolt SD15 electric drive.
Spirit Yachts managing director Nigel Stuart commented, “The lightweight electric drive system (weighing 46.5kgs) uses hydro generation via the propeller to regenerate the batteries whilst sailing.
“Regeneration will depend on sailing speed, but it is realistic to see 1.5kW whilst sailing at five knots. The equivalent energy generated would be boiling a kettle, which is one of the highest power consuming appliances you would find on a yacht, or in your home for that matter.”
Spirit Yachts is working with OneSails GBR (East) to develop a solar solution for the Spirit 44E’s sail wardrobe.
John Parker from OneSails GBR (East) explained, “We are exploring the use of the very latest ‘thin cell’ PV panels with the intention of utilising the yacht’s 4T Forte sails and covers as sources of electrical generation. The work is cutting edge, therefore at this stage a number of the details remain confidential.”
OneSails’ 4T Forte sails are currently the only sails made from a cloth that can be recycled.
Manual Lewmar winches will give a nod to more hands-on sailing, whilst a carbon mast and boom from Hall Spars will ensure her rig remains lightweight. A large lazarette under the aft deck will house a tender with an electric motor, and a 40” Mahogany and stainless-steel steering wheel will be fitted for easy handling.
Down below, the Spirit 44E’s eco credentials continue throughout. A reversible heating/air- conditioning Webasto pump will heat and cool the yacht using minimal power. All lighting will be LED and a Webasto 4.2 gallon 115v/750W heater will provide hot water. At the owner’s request, there will be no hydrocarbons onboard and any cooking will be done on a spirit stove.
