You are correct, Golden Hinde did end up at Pin Mill on the Orwell.
I know this because I bought her in the latter half of the sixties. I acquired her from a chap that raised her from a sunken situation that I have no knowledge of. Just to say that she had no mud or bad staining in or on her.
She did have a bad leak from a broken beam shelf in the starboard quarter. I borrowed a thirty ton jack from a friend and jacked her up between tides as she lay against the hulk of a Thames barge. I then plated the beam shelf with steel plates and bolted through the shelf. She stopped leaking. I think from memory she was teak planked.
I loved that boat but had to sell her because I was drafted overseas .
At the time I was a diving instructor at H.M.S. Ganges.
I sold her to a gentleman by the name of Southgate.
In 1972 I moved to Australia and have yet to make a return journey.
