To improve the boat range and running time, to be able to offer a full
day of service in respect to the environment and with maximum comfort for passengers,
many innovative ideas have been integrated into Alt.En
design.
Find below some of the features that make Alt.En boats
efficient, cost effective, comfortable and environment friendly.
Enhanced hydrodynamic efficiency
- Reduced hull drag (using the latest CFD technology at design stage)
- Immersed electric engine. Using this technology, a very high efficiency
is reached by removing needless transmission gears
- Reduced bow wave and wake at operating speed
- Custom propellers
- Podded propulsion, leading to a very high maneuverability
Optimized structure
- Lightweight fiberglass composite hull structure
- Lightweight battery pack
Energy management
- Long life battery pack using Ni/Cd technology
- Photovoltaic panels (from 10% up to 20% extra running time)
- Induction fast recharge (Alt.En patent). Up to twice the initial range,
depending on call duration
- Optimized battery recharge cycles depending on ferry circuit
Environment friendly and comfortable
- No greenhouse gas
- River bank care du to reduced wave
- Silent
- Large passenger area
- Stable
