Curvelle stands for flexibility. The cabin’s insulated sliding walls can be opened or closed, any of the beds can be separate singles or together as doubles.
For extra large suites the beds are turned into sofas and sliding walls open to turn two cabins into one extra large suite with sitting room and his and hers bathrooms.
In this way the six double cabins can be swiftly changed (by the crew) to three suites or a combination of twin/double/suite cabins. (over twenty lay out choices on the same yacht are possible)
