"Le Passeur" in La Rochelle |
The first electric boat for public transport
“Le passeur” (The ferryman) is the result of new and original specifications
never gathered together until that time. In 1998, Alt.En built a first electric boat for
La Rochelle city harbour.
It provides a shuttle service between the two sides
of the old town harbour, where a 3 minutes trip allows a 45 minute walk to be saved. This small
ferry has been such a success that a second unit has been launched in
2003 to face the increase of activity.
Design and build following an innovative approach, “Le Passeur” currently
operates yearly, seven days a week, from early in the morning till late in the evening,
and even at night during summer.
