[5] Versions of the design were also built by many other builders using an assortment of materials for hull construction, including wood and ferro-cement.
The company completed about 72 examples of the design between 1977 and 1985, including some boats delivered as bare hulls and kits for owner-completion.
The number reported as completed varies, depending on whether boats sold as bare hulls or kits are counted.
[1][3][4][7] The boat was the company's first design produced and it took founder Mike Riding almost four years to build the hull molds for the start of production.
It has a cutter rig, a spooned raked stem with a teak bowsprit, a canoe transom, a transom-hung rudder controlled by a tiller, or an optional wheel and a fixed long keel.
[1][3][4] The Mark II version has a taller rig of about 7.10 ft (2.16 m), designed by Raymond Richards and has a shorter aluminum bowsprit.
[1][4] The boat is fitted with an inboard diesel engine of 40 hp (30 kW) for docking and maneuvering.
The side decks are 22 in (56 cm) wide and have a non-skid surface of ground walnut shells.
