A category B approved electric boat
The Riva El-Iseo is the first all-electric motorboat from the brand, which is launching its new E-Luxury range with a focus on sustainability. Like all the brand's creations, the Riva El-Iseo was designed by Mauro Micheli and Sergio Beretta, founders of Officina Italiana Design, in collaboration with the strategic product committee headed by Piero Ferrari and the engineering department of the Ferretti Group. It is also presented as the first electrically-powered boat approved to sail in category B, i.e. force 8 wind and 4 m high waves. However, given the boat's design, its program will be more suited to calm water sailing in sunny weather.
Elegant, sophisticated lines in pure Riva style
This first model is a 27-foot - 8.40 m - runabout with a 2.5 m beam. Its elegant, sophisticated lines are unmistakably Riva. It inherits its hull design from the multi-purpose Iseo model, which features thermal propulsion.
On board, you'll find typical Italian features, such as the varnished mahogany of the deck and aft platform, the stainless steel details of the side grilles and the refined cushions in sky-colored fabric. These elements, combined with the modern, linear design of the deck, create a contrast between traditional and contemporary, the concept of the boat.
A new deck plan design
The deck, cockpit and helm feature a completely new design, while the color of the first hull is also new for Riva: California Sky Blue. Nevertheless, the aquamarine line found on all Riva boats is still present.
Sterndrive propulsion coupled with an electric motor
The Riva El-Iseo retains the traditional sterndrive propulsion and features an all-electric Parker GVM310 motor from Parker Hannifin, the world leader in mobility technologies in the USA. With an output of 250 kW, which can be increased to 300 kW, the Parker GVM310 offers a cruising speed of 25 knots and a limited top speed of 40 knots, with torque claimed to be superior to a similar-sized boat powered by an internal combustion engine.
For added stability, El-Iseo features automatic trim control and a Zipwake trim correction system.
El-Iseo is equipped with a high-energy-density lithium battery supplied by Podium Advanced Technologies, an engineering company specializing in batteries, automotive design and motorsports. Lightweight and 10 times more durable than lead-acid technology, the 150 kWh, 800 V batteries feature 2 charging modes, normal and fast, for a 20% to 80% charge in 75 minutes. Charging ports are located under the steel grid on the port side.
Battery configuration optimized for safety
The battery pack has a "redundant design configuration", with two independent blocks. So if one of the batteries fails, it doesn't affect the operation of the second. For safety, the batteries are sealed and liquid-cooled, an efficient system for rapid heat transfer. They are located at the forward end of the hold, under the bimini-T-top compartment, between the dinette and the aft sundeck, for easy access and inspection. Finally, the batteries benefit from additional thermal insulation in the form of a special coating inside the fiberglass panel. This material ensures good fire resistance despite weighing just 5 kg, and is commonly used in the aerospace industry. It consists of fiberglass panels that create an effective heat shield against flames. A gas sensor is also installed to detect leaks
A fully digital dashboard
The fully digital instrument panel features two touch screens, from which all cruising and on-board system information can be controlled: a 9" or 12" Simrad plotter and a 12" Böning display showing all battery status and cruising mode information. The design of the steering system and its integration with the on-board systems are designed by Xenta.
Three navigation modes
Riva El-Iseo offers three navigation modes whose names pay homage to tradition and are inspired by classical music: Adagio, Andante and Allegro.
- Adagio this is the Eco mode, designed to optimize cruising performance. Maximum speed is 5 knots and acceleration is limited, reducing energy consumption and maximizing range for up to 10 hours of cruising.
- Andante cruising speed and acceleration are comparable to those of a boat of the same length powered by an internal combustion engine, reaching a maximum planning speed of 25 knots.
- Allegro this is the sport mode, with no engine limitation, enabling a top speed of 40 knots with electrifying acceleration.
To maintain battery life, when the residual charge drops to 20%, giving a range of around 10 nautical miles, the boat automatically switches to Adagio mode, regardless of the cruising mode selected. This allows the owner to save energy and safely reach a mooring or recharging point.
