eco tender 25 m

A new Perini Navi motor yacht has been launched. The historic shipyard of Viareggio, specialized in the production of large sailing boats, has launched the Eco Tender, a 25-meter hybrid propulsion boat designed as a support for large yachts.

Just look at the colors to understand that it is a Perini boat. The dark blue hull and the red waterline are trademarks of the shipyard’s sailing fleet. Identifying it as a simple means of support, however, is not enough because this hull has all the credentials to be considered a miniature mega yacht. Hence the definition of “super tender”, an aluminum boat, the first planing motor yacht by Perini Navi with the quality of a superyacht.

How was Eco-Tender born?

This project was developed around the desire of some owners to have an extension for their sailboat, a 52-meter Perini Navi sailboat. The need was to have more flexible spaces for individual guests or children and a more comfortable means of transport than a normal RIB to explore the areas below the coast and also spend time in the roadstead. The answer was a boat that would appeal to the mother ship for quality and comfort, but that would also be independent. And so here is the Eco Tender, a 25-meter motor yacht that sums up these characteristics.


The Eco Tender is a hybrid

In a cutting-edge yacht, today cannot miss a hybrid system. The 25-meter Perini Navi was developed by Siemens and is divided into 4 different modes:

Diesel: two MAN(2x1213kW) diesel engines power two Hamilton waterjets for a maximum speed of over 30 knots.
Hybrid: one engine drives the jet and also acts as a generator, powering the electric motor that drives the other jet.
Diesel-electric: a 130kW generator supplies electricity to the two electric motors to drive the waterjets.
Zero emissions: for maneuvering or small, emission- and noise-free journeys, a set of batteries powers both jets via electric motors, for speeds of 8 knots and a duration of approximately one hour.

Design and layout

The aft cockpit is equipped with lounge seating, sunbathing areas and a small beach. In the bow deck there is a dinette, the interiors are in brushed teak combined with white lacquer and have a dinette-sitting room and a kitchen on the main deck. Below deck, there is a full beam VIP suite, a double forward cabin and a third cabin with twin beds, all with private bathroom. In front of the bulkhead of the engine room, there is a crew cabin with independent access.

All the on-board systems, including the hybrid propulsion, can be managed using high-resolution 4K touch screens, trackballs, and joggers. The monitors rise to different heights, in dashboard or chart/navigation mode, and also offer an augmented reality function that superimposes video images on navigation data.

In addition, the Anchor Watching System (AWS) displays and controls all the systems required to monitor the boat.
when he’s at anchor. In fact, it provides 360° images around the boat and monitors marine traffic using radar systems, thermal imaging cameras, and a range of other devices.
or a research projector. It can also be programmed to emit an approach alarm.

Equipped with a dual VSAT system for Internet connection and three Iridium phones, the Eco-tender is able to stay connected to the mother boat at over 100 Mbps even tens of miles away.
