I was 2/0 on the Kona/Sir John Hunter in the late 80's, she was also a heap of s...e. The Pumproom was dangerous to work, the main cargo valve hydraulic pumps in the duct keel weren't strong enough to control the valves when under pressure and had to be helped with a big stilson, the pumproom bulkhead was doubled with repair patchhes and still had to be inspected in heavy weather in case the cracks got worse.
When I joined the Old Man greeted me with "Some of the valves don't pass, and some of the bulkheads are sound".
Wonderful! Whilst I was away the Kowloon Bridge broke up. My wife got even more worried when she realiosed that the Kona was a sistership!
