Designed by Stephen Jones for the 1986 Half Ton Cup, and built by her first owner, Howard Sellars. Composite GRP/Kevlar/epoxy/foam sandwich construction (the hull was epoxy coated in 2011). Yellow/cream coloured hull and light grey painted non-slip decks. Lead fin keel. Tiller steering to spade hung rudder. Self draining cockpit.

Modified in the stern to a Jones design (when she was known as ’Sorceress’) for a later Half Ton Cup. Further modifications, including removal of ’frog eye’ bumps at the forward station in 1990. Hull in way of keel rebuilt in a heavier lay-up by Reg White Ltd. under surveyors supervision to repair and strengthen for future use.
