A review for yacht charter company Sailing Europe, noted, the "Beneteau Cyclades 50.5 most commonly comes as a version with 3 showers and toilets along with a deck shower. Since this yacht is 15.6 m long overall and is 4.89 m wide it is not made for high sailing performances and top speeds for competitive sailing. This yacht is designed to accommodate a lot of people and to provide them as much comfort and space as possible."[9]
