I have started a profile for David Hoy (not a relation). He was a Scottish born shipwright who trained in Boston, Massachusetts and then migrated to Tasmania in the 1820s. He was drawn to Tasmania by the wondrous properties of the Huon Pine for shipbuilding (it is an amazing timber, but logging is now forbidden). David Hoy worked with convicts at two of the worst penal settlements known - Sarah Island and Port Arthur. He used convict labour to build numerous ships and taught the convicts, as well as negotiating a better deal for them in return for their cooperation. The profile is pretty sketchy thus far and there is a lot of info I have collected but need to source properly and confirm. I'm interested in locating information about him in the US where he did his training to be a master shipwright. He has an interesting story.
This is a link to Sarah Island, the video clip is worth watching.
