The LIBERTY 23 (19 built) varied slightly with the same hull, more ballast, with slightly more sail area. When the free-standing aluminum masts for the LIBERTY (cat ketches) were no longer available, Hunter introduced a gaff rigged sloop version with the same hull called the MINSTREL which was built until 1993.
