Ross Muir's son, Jason, was a national champion in the Sabot class and more recently, in July 1990, represented Australia in the World Youth Series for 420 class yachts in Holland where he and crew, Dominic White, finished third overall. Jock too, started racing in small boats: "It was in 1931 that a true craftsman, "Skipper" Batt, built the original Kittiwake for me in Napoleon Street, Battery Point, only a few hundred yards from where Muir's Boatyard is now located. The fee was 40 pounds sail away and she was launched on September 13, 1931. Also about this time, he built the 16-foot skiff Gumnut II for Neall Batt. Both were beautifully built from Red Cedar.Two years later, Alf Gough, former Hobartian Bill Humphries and I, teamed up to win the Stonehaven Cup for 12-foot cadet dinghies in Adelaide." After her win in the Stonehaven Cup, she was handed over to Max Muir, who repeated the performance by regaining the cup in 1935. Three years later, Kittiwake was back to win the Stonehaven Cup for a third time under the guidance of Ediss Boyes, who had earlier purchased the dinghy from the Muirs. He later sold her to well-known helmsman Ken Johnston of Sandy Bay. But the Kittiwake-Muir relationship was not to end there.
The winners: David Cook, David Norman and Greg Muir haul in Kittiwake II after winning all the heats and invitation races of the Stonehaven Cup in 1967, a record which was held for many years. David Norman has since competed in several Sydney-Hobart and Maria Island races. He was sailing master on The Roperunner, in the 1989 Sydney-Hobart.
