[3] The Matilda 20 built by Ouyang Boat Works is a recreational keelboat, with a round-bilge hull constructed predominantly of fibreglass, with wooden trim.

It has a masthead sloop rig, a raked stem, an angled transom, a transom-hung rudder controlled by a tiller and a lifting keel with a weighted bulb.

[1][3] The boat has a draft of 4.16 ft (1.27 m) with the lifting keel extended and 9 in (23 cm) with it retracted, allowing operation in shallow water, beaching or ground transportation on a trailer.

[3] In a 2010 review Steve Henkel wrote, "the design features a relatively wide beam for her length ... that, combined with her full-width cabin house (no side decks), makes her relatively roomy, but also results in a somewhat awkward appearance—and ironically, compared to her higher-topside comps, the Matilda ends up with a lower Space Index.

Best features: The lifting keel has a bulb at the bottom, helping (along with a high D/L) to give good stability under sail, as well as a motion index higher than her comps.
