I found this delightful story by a great-grandson (?), Perhaps made in the 1950-60 timespan.  (More about currachs:  https://therondoutrower.com/currach-traditional-irish-boat/)

The Youtube post says:
“Thanks for taking the time tolook at this video. One of the reasons I put it up here is that I thought some1 might be able to date it. I’ve been unable to date it but here is the info I do have. his name is Michael o’Shea. He was harbour master and master builder at Brandon Creek. He was born in 1878 and died in the early 1960’s aged 80+. He looks like he’s in his mid-60’s here which could put the video somewhere in the 40’s. I’m still working on dating it. Once i do I’ll edit the post.”
