Delivery trips
Much of Jock's life on the sea was concerned with sale and delivery trips, valuations and survey work. The delivery trips included a Hobart to Sydney run on the Max Creese designed class "A" yacht Mavis in 1948. She was sold by the late Ted Domeney of Hobart to Archie Robertson of sydney (formerly of Hobart).
