In a beautiful fusion of classic design and modern technology, the Cumbria based boatyard Patterson Boatworks has revealed its latest project: the FE23, a 23kW electric powered 7.25 metre slipper launch that is fast, quiet and graceful, yet produces no emissions.
Ideal for both classic yachts looking for a launch to complement their lines, or for more contemporary superyachts seeking a distinctive, zero emission support craft, the FE23s are hand-built with exceptional care and pride to the same exacting standards as all boats. Built for strength and lightness, the hull is foam cored carbon composite, while the topsides are a mix of English oak, Douglas fir and teak inlaid with aluminium, with English cherry and oak for the interior woodwork.
However, the sleek, tactile appearance of the FE23 belies her impressive power, for underneath the rear seating lies the epitome of modern, ecologically sound technology — a 144 volt battery array that is guaranteed for up to 3000 recharges and capable of driving the boat at speeds of up to 15 knots for one hour, or 7 knots for up to eight hours. She has a maximum range of 80 miles on a single charge, giving her more than enough endurance for day trips and ferrying owner and guests between the yacht and the shore.
Simon and Hamish Patterson, who head up the team at Patterson Boatworks, appointed designer Nigel Irens to draw the sleek, efficient lines, and then invested many months in seeking the perfect propulsion system in response to the owner’s need for clean, green speed.
The result was the selection of a long life lithium iron phosphate battery pack supplied by LiFeBATT which is more likely to be found underneath the bonnet of an electric car. The LiFeBATT is just one third the weight of an equivalent conventional lead battery yet, when combined with a four bladed propeller and a slippery hull, provides a powerful and smooth ride.
Simon commented: “This launch is a joy to drive and ride in. Our quest for the perfect electric power source has really paid off, and the overall design of the FE23 accommodates all the needs of her owner, who lives on the waterfront and expects to use her a good deal. She’s a wonderful blend of the old and the new, traditional skills married to state of the art hull dynamics and propulsion technology, and highly versatile – making her ideal as a high class superyacht tender. She offers performance as well as space and understated luxury, but with no noise, no oil and no emissions."
