Scale: 1:48. Plan showing the body plans, sheer lines and longitudinal half-breadth for building Childers (1827), Cruizer (1828), Favorite (1829), Hyacinth (1829), Racehorse (1830) and Hazard (1837), all 18-gun flush-decked Ship Sloops similar to the Cruizer (1797) brig. The plan was cut in two along the midship section and a new piece inserted for the proposed (and approved) lengthening for the last four ships and the alterations to the mast positions as a result.
