The fully-electric E-tender 460 has recently been launched by Naumatec, the brand acquired by Nuova Jolly Marine specialising in custom superyacht tenders. The tender is the first of Naumatec eco-friendly fully-electric tender range.
The e-tender is built using Vacuum Resin Infusion, a method which saves weight and increases mechanical strength, while also contributing to reducing the emissions of volatile organic compounds (VOC) during lamination. Her hull has been optimised to ensure high performance for the propulsion system and manoeuvrability in confined spaces. Designed by Federico Fiorentino, the e-tender is built with a peculiar “D” shaped Hypalon tubular that ensures floating and works as a fender.
Huracan has designed, specifically for Naumatec, an innovative trimming drive that ensures a low steering radius and good handling even in reverse.
Thanks to the electric propulsion, which weighs 40 Kg for 15 or 30Kw of power output, the new Naumatec e-tender 460 is silent and produces virtually no emissions. In addition, there are no issues in storing it inside a megayacht, it requires little maintenance and can access the protected areas.
The tender can carry up to six people and has a dry weight of 480kg when equipped with a 15kW single engine battery, or 620 kg with the best performing engine of 30kW and two batteries.
Naumatec basic 15kW engine version has been tested, and even if further tests are yet to come, the provisional data recorded for the E-Tender 460 has been satisfactory: the tender has proved to be able to reach a top speed of 38 km/h, with a consumption about 20 kW/h, meaning a 40-minute range. At a speed of 8-10 km/h, the consumption drops to 3-4 kW/h, meaning an increased range of up to 3-4 hours.
Naumatec is still working to improve the whole system, and tests on the 30kW version are also going to be conducted soon.
