Again as skipper, Jock competed in the 1960 Bruny Island race in the now Sydney-owned Lass O'Luss. The race was sailed in very light airs for most of the journey and Lass O'Luss took two and a half frustrating hours to get from John Garrow light to the finishing line. Nevertheless, she crossed first followed by Southerly Buster (Ken Gourlay) and Roana (Graham Blackwood). Jock's final offshore racing season was in 1972-73, when as owner/skipper, he sailed Patsy of Island Bay and won both the Maria and Bruny Island races taking out the Points Score Plaque for the season. In the Bruny Island race he was the only finisher from 15 starters, all other yachts retired because of gale-force winds. A 55 knot-plus southerly hit the leaders approaching Friar Rocks which scattered the fleet: "After passing Cape Connella on Bruny's east coast, the fresh southerly continued to increase in velocity, even in excess of our ananometer which had a maximum reading of 55 knots. It reached its peak as we approached the Friars Passage, closely reefed with storm jib. All on board were very much relieved once we had passed through the Passage, with no other yacht visible. About halfway across to South Bruny lighthouse we were able to see another yacht making heavy weather of it, as we had done, only later to see her square away and head north, as indeed had all other competitors, leaving Patsy as the only yacht to complete the course. I was very proud of her that day."
Dinghies, Skiffs, Sharpies and Diamonds
The Cadet Dinghy Class is one of the oldest one-design racing yachts still in competition. It was adopted as a training craft by the Royal Yacht Club of Tasmania in 1924 after it had first been introduced in Sydney waters from a design by Mr A.C. Barber, principally for the training of cadets. In 1927 Lord Stonehaven, Governor General of Australia, presented a perpetual trophy for interstate competition for the dinghy class which is still raced for today in alternate states. The first dinghy races in Hobart were started from a line off "Skipper" Batt's jetty, with the course bounded by Secheron Point and Long Point. Many members of the Muir family have started sailing in this class. Today, nephews and grandchildren of Jock Muir continue the fine family tradition of dinghy racing. Tim and Ben Muir, (sons of Jock's son, Greg) have recently moved from Sabot racing into Flying Elevens with early success.
