Lady B

Vitters Shipyard created a sailing yacht that combines exceptionally high performance levels with superlative comfort. This 44.7-metre striking sloop is designed by Dubois Naval Architects, who achieved an excellent blend of naval architecture and ergonomics in order to offer fast sailing, state-of-the-art technology and cutting edge styling. 

Lady Bs slim profile features a single-level superstructure, which keeps weight low and reduces windage. She is constructed in aluminium and has a high aspect ratio rig with carbon mast and furling boom. Lady B is equipped with PBO standing rigging to enhance performance. Her compact lifting keel system generates a variable draught from a minimum depth of four metres to a maximum depth of six.
