Riva 27 El-Iseo

Riva introduces the El-Iseo, its first fully electric powerboat, marking a bold step into the E-Luxury market with sustainability at its core. This 27-foot (8.40 m) runabout, with a 2.5-meter beam, offers a blend of modern technology and timeless design. Drawing inspiration from the popular Iseo model, the El-Iseo retains the classic hull while adding a fresh, eco-friendly twist to Riva’s legacy of elegance and performance. It sets a new benchmark in luxury boating, merging environmental consciousness with iconic craftsmanship.

Electric Essence

Electric Essence

The El-Iseo is the fully electric version of the iconic 27-foot Iseo, powered by a Parker GVM310 engine. It offers a top speed of 40 knots and up to ten hours of navigation in economy mode, combining high performance with sustainability. Equipped with a lithium battery pack from Podium Advanced Technologies, the El-Iseo also features integrated onboard systems managed by innovation leader Xenta.

Modern Elegance

Stepping aboard the El-Iseo, the boat’s dual identity becomes instantly clear. Classic Riva elements—elegant finishes, iconic colors, and meticulous detailing—stand alongside a modern helm station featuring a fully digital touchscreen dashboard, designed with a nod to the analogue displays of past models. The El-Iseo perfectly embodies the Riva spirit, balancing a deep reverence for its rich heritage with a relentless pursuit of innovation and cutting-edge technology.

Build your El-Iseo with Jeff Brown Yachts to experience this fusion of tradition and modernity firsthand.

Standard Features

Lithium Battery

High-intensity lithium batteries: more efficient, lighter in weight, and capable of lasting up to 10 times longer than leadacid batteries. An excellent choice for yachting applications.

800 V

150 kWh

Podium Advanced Technologies

A pioneering company in the R&D of high-performance battery systems and automotive solutions for motorsport and niche markets. FIA chose Podium as the single supplier of Battery Systems for the next GEN4 Formula E world championship, set to debut in 2026.

Fast Charging 75-minute recharge time. Charging from 20% to 80% with an optional 75 kW fast shore connection.

Redundant Setup

The batteries are organized into two distinct blocks, safeguarding against the possibility that the malfunctioning of one block will not compromise the functionality of the entire battery pack.

Placement
The batteries are positioned (fiberglass structure of the sofa) such that accessibility and inspectability through a specific panel appear to facilitate maintenance and inspection.

Sealed & Thermally Insulated
The batteries are engineered to function within a stable, sealed environment, ensuring the stability of their internal conditions.

Liquid Cooling
Considered the most efficient battery cooling solution.

Exhaust Pipe
An exhaust pipe on the port side outlet allows venting in case of overpressure.

Gas Sensor
A gas sensor, triggered in the presence of the latter.

Fireproof Shield

A coating of FR.10 & FR3D fireproof composite materials is positioned on the inner side of the VTR closing panel. The material utilized in the aerospace industry, which is remarkably lightweight (only 5 kg), providing an efficient thermal shield against flames (-197°C to +1500°C for serval hours).

RPM
The RPM of the propulsion motor is also shown inside the analogic indicator.

Charger Icon
The connected and locked shore power indicator.

Key Icon
The state of the key contact is inserted.

Interceptors
The two analogic indicators on either side of the central indicate the position data of the left and right interceptors, respectively, as a percentage; The same data is also displayed in digital format below each scale.

Steering
The lower analogic indicator shows the rudder angle, that is, the direction in which the stern drive is turned.

Auto Trim
It automatically adjusts the stern drive's angle of incidence based on the engine's rotation speed to maximize the vessel's performance in terms of speed and autonomy.

Auto Course
It corrects any deviations of the vessel caused by wind or currents, ensuring that the boat proceeds straight while keeping the rudder centered.

State of Charge (SOC)
The battery status data is also shown inside the analogic indicator.

Range
The indicator displays the autonomy in nautical miles (NM).

ECON
Expressed in kWh/NM, representing the energy consumed by the batteries for each nautical mile traveled during the cruise.

Trim
Representing the angle of incidence of the stern drive, adjustable through the respective control on the throttle.

Water Level
The level of fresh water tank is also shown in the analogic indicator

Motor Temperature
The temperature of the electric propulsion motor is displayed in degrees Celsius (°C)

Trip Log
Represents the miles navigated.

Energy Consumption
The data of energy consumed by the batteries, expressed in kWh.

Allegro / Andante / Adagio
Allow to activate the 3 operating modes of the engine.

Allegro
The TOP speed. Allows use of the yacht at full power, achieving maximum performance in terms of speed (40 kn) and acceleration. This mode can be activated only if the State of Charge (SOC) is above 20%.

Andante
The CLASSIC speed. Allows the use of the boat prioritising navigation autonomy. The top speed is approx 25 knots, corresponding to an engine speed of 2800 rpm. This mode can be activated only if the state of charge is above 5%.

Adagio
The ECO speed, where the speed is limited to a maximum of 5 kn, as well as the acceleration, containing consumption and maximum autonomy to 10 hours of navigation.

Return to Home
To prevent the boat from running out of battery, when the State of Charge (SOC) drops below 20% (10 nm approx) the Adagio mode activates automatically, therefore the maximum speed switches to 5 kn. In this case, the red indicator light (turtle) is illuminated.
