Sirena 48 Hybrid: Coupé version celebrates its world premiere at the Cannes Yachting Festival 2024

Elegance meets innovation

The core DNA of the Sirena 48 remains the same in the new hybrid version, making the three-cabin yacht as attractive as ever on the market for small to medium-sized yachts, according to the shipyard. The difference between the two models is that the open flybridge has been replaced by a coupé-style superstructure roof. This is curved and fitted with glass and solar cells. The hardtop not only gives the Sirena 48 a sportier look, but is also intended to provide more daylight in the saloon. The new superstructure also reduces the weight and wind load of the yacht and improves the performance and range of the electric drive. Solar cells integrated into the roof of the superstructure help to increase the range of the yacht in electric-only mode.

Silent drive

Powered by two 213 kW electric motors, the Sirena is expected to reach a top speed of 14 knots. In electric mode, it can draw energy directly from the batteries to travel up to 30 nautical miles before the generators have to be switched on. In this way, the ship can leave the harbour or anchorage unnoticed without the noise and exhaust fumes of a diesel engine. The battery capacity is said to be 78.2 kWh. Two batteries were installed for this purpose.

For a greater range and higher speed, the two 180 kW generators are switched on to generate the power to drive the boat and charge the batteries. The advantage of the generators is that they can be set up independently of the propellers, which reduces noise and vibrations. The generators do not need to be started for more than eight hours, even when the air conditioning is running and the kitchen or AV systems are in use. The integration of e-Motion's hybrid system can reduce fuel consumption by up to 35 per cent and maintenance costs by 10 to 15 per cent, depending on how the yacht is used, according to the shipyard's press release. The battery pack can also be upgraded on request. This allows the Sirena to be operated for up to 16 hours without a generator.

Those who do not like the Sirena 48 will in future also have the option of specifying the coupé design on the Sirena 58, 68, 78 and 88.
