The Countess is a motor boat from Le Boat. Le Boat is not a shipyard but Europe's largest inland charter operator, trading under this name since 2001 and descended from the Blakes and Crown Blue Line fleets. Its boats are classed by its own names - Horizon, Vision, Classique - and built to its specification for licence-free hire. The hull measures about 10.2 metres. It sleeps up to 6.
Adriavela lists 18 boats of this model. They were built between 1999 and 2002, so the layout and the equipment differ from one hull to the next. The hulls here carry 2 cabins and 6 berths.
They leave from bases up and down the coast, Hesse, Saint-Jean-de-Losne and Saint Gilles among them. Under power the day is planned by distance rather than by wind, which suits a group working through a lot of coast in a week.
