A dayboat of classic elegance

British shipyard Spirit Yachts has developed a limited edition electric foiling motorboat. The SpiritBARTech35EF is based on the shipyard's well-known classic design. The narrow profile - just 2.3 m beam and 35 feet long - is marked by a deep-V hull with slim water inlets and a unique step in the center of the boat, as well as a domed transom. The elegant dayboat is built from cold-molded wood, with a carbon-fiber-reinforced hull, and a total weight of one ton. The wood used comes from exotic species such as yellow cedar and African Sipo, and is finished in a high-gloss lacquer.

BAR Technologies foil technology

While the design is in-house, the technology has been entrusted to BAR Technologies for its expertise in America's Cup simulation and design. The foils are made of solid titanium and comprise a T-shaped rudder at the stern to control heel, and L-shaped foils at the bow with flaps to control roll. This technology is derived from systems developed by BAR over the past 10 years, but also from the foil-assisted Princess R35 sportboat unveiled in 2018.

An incredible range of 100 nautical miles at cruising speed

The SpiritBARTech35EF takes off at 14 knots, with the ability to pass through swells up to 1.5 m high. It is said to be capable of reaching 30 knots, and has a long range of 100 nautical miles at 22 knots. Flight altitude is adjusted automatically via various steering sensors. Once the foils are retracted, the dayboat recovers a draft of 0.3 m for sailing in shallow waters.

The well-protected cockpit in the center of the boat can be configured for six people, or closed for a sportier two-passenger experience.
