Perini Navi’s new Eco-tender is the first motoryacht the company has launched since rebranding and its first ever planing yacht. The Eco-tender is effectively a mini superyacht conceived for her experienced Perini Navi owners.

  • Multiple mode hybrid propulsion
  • Superyacht quality aluminum build
  • In-house design and naval architecture
  • I-Bridge Multitouch 4K bridge
  • Aft and forward guest cockpit

The project grew out of initial discussions with the owners for a bigger sailing boat. While the owners were very happy with their existing 170-foot (52-meter) Perini Navi sailing yacht, their needs had evolved over the years and what they really wanted was not a bigger boat, but more flexible cabin space to accommodate single guests or children. As they prefer to anchor offshore, they also wanted to be able to explore closer inshore in something more substantial than a conventional RIB.

The answer was a vessel with the same graceful looks, quality feel and luxurious comfort as the mother ship that could provide additional cabin space and be able to operate independently as an extension of the sailing yacht.

“The classic exterior styling of the Eco-tender shares the same family feeling as Perini Navi’s historic sailing fleet, right down to the dark blue hull and red load line,” says Lamberto Tacoli, Chairman and CEO of Perini Navi. “But it is clearly no ordinary tender and represents a new breed of super-tender with amenities and technologies to match. As a boat designed and built with a yacht mentality that mirrors all the high-quality hallmarks of Perini Navi, this cutting-edge tender breaks new ground as the brand continues to refine its product range to meet the evolving demands of the market.”

4-mode hybrid propulsion

The innovations start with a sophisticated hybrid propulsion system developed by Siemens, which provides four operational modes for maximum flexibility:

Diesel mode: twin MAN diesel engines (2x1213kW) power two Hamilton waterjets for a maximum speed in excess of 30 knots.

Hybrid mode: one engine drives its neighboring waterjet and also serves as a generator for an e-motor to power the other waterjet.

Diesel-electric mode: a 130kW generator supplies electricity for two e-motors to drive the waterjets.

Zero-emission mode: for completely silent and emissions-free maneuvering or limited cruising, a battery bank can power both waterjets via the e-motors at around 8 knots for up to a hour.

In battery mode, the tender will be able to cruise at low speed in marine parks or other environmentally sensitive areas with no emissions and no noise. But at the request of the owner, close attention has been paid to minimizing noise in all propulsion modes and contractual sound levels are below 55dB throughout.

This is the first time such an avant-garde hybrid system has been installed on a superyacht tender,” says Luca Boldrini, Sales Director of motoryachts at Perini Navi. “The initial impetus came from the tech-savvy owners who wanted a vessel that impacted on the environment as little as possible, but the know-how we bring away from the project will be carried through into the future.”
