Even just five years ago, electric runabouts were more novelty than reality. Today, dedicated zero–emissions yacht tenders are not only becoming more commonplace but are actively being sought out for their benefits over traditional internal-combustion-powered versions. Responding to this growing demand, Williams Jet Tenders has announced an electric version of one of its best-selling models: the EvoJet 70.
The company promises the 23-foot Electric EvoJet will retain all of the high-end features which made it a leader in its segment, such as a carbon fiber T-top, premium audio system, LED lighting and single-point lift engineering, while adding the benefits of zero-emissions propulsion. The EvoJet 70E will utilize an electric system from EVOA Propulsion and a 58.5-kWh lithium-ion battery bank supplied by Williams Advanced Engineering.
In its preliminary sea trials, the Electric EvoJet hit a top speed of 35 knots, with handling and seating capacity matching its predecessor, accommodating up to 13 passengers. It is able to fully recharge in just one hour using a fast charger, providing 56 minutes of operation on what the manufacturer calls a typical activity cycle. A custom Garmin multifunction display provides real-time insight into range, battery temperature and charging status.
“We are incredibly excited to introduce the Electric EvoJet to the market as a technology demonstrator.” said Mathew Hornsby, commercial director at Williams Jet Tenders. “We continue to thoroughly test this model to ensure it meets our exacting standards but are pleased to showcase what’s possible with the technology at the Cannes and Monaco yacht shows. We look forward to discussing yacht integration opportunities with OEMs, as well as the future of electric boats in the marine industry.”
Propulsion Tech
At the heart of the Electric EvoJet is the EVOA electric propulsion technology. Axial flux motors provide the best-in-class power to weight ratio, with four times the power density and half the weight of comparable systems and power options ranging from 150 to a whopping 650 hp. They are available in outboard, inboard, sterndrive jet drive and V-drive configurations. Aside from zero emissions, the EVOA propulsion system also has the benefits of less noise and, thanks to fewer moving parts, significantly reduced maintenance.
