Considered to be the finest of the Laurent Giles Westerly designs the Westerly 33 yachts were designed to fall between the Westerly 31 and 36 models and although she comes midway between these sizes the beam is just marginally smaller than that of the larger design.

Between 1977 and 1980 two hundred and forty centre-cockpit Westerly 33’s were built.

If you own a Discus or Westerly 33 we would be pleased to hear from you.
