Wednesday 9th October
David is a retired Master Mariner and an expert in dynamic positioning of vessels. He is a Fellow of the Nautical Institute and has been involved in preserving several historic ships, including the Norfolk Wherry "Albion", which he skippered for many years. In this talk he will tell us about his experiences working as Navigating Officer in the research vessel RRS “John Biscoe” in Antarctica during the 1970s. At that time, the technology was more akin to that of Shackleton and Scott than to the 21st century; soundings were in fathoms and positioning was by sextant and chronometer. He will tell us about work in Antarctica from the standpoint of operating a ship, including some of the more humorous episodes.
