Notes: A fin keel version draws 2.67', but most were built with bilge (twin) keels.\nThe fiberglass Mk III version was the result of a major re-design and was built by Hurley Marine Ltd. Including a round bilge design vs. the hard chine on the Mk II, a 40% increase in SA and bilge keels made of FG moulding with interior ballast.\nAn optional inboard engine was available.\nLater a Mk 4 version (1973-1974) was built based on the Mk 3 but with 4 berths. Only about 25 of the Mk 4 were built.
