I thank David for a link to an article about Minoru Saito
And I thank Stephen for an article about Jeanne Socrates.
I know of both of them. I do no know or care which of us is oldest by whatever number of days. This is nothing I ever even thought about; and I think I read some time ago of someone who completed a circumnavigation in his 80s, though I am not certain.
In the body of the article about Jeanne Socrates, it does add to oldest ‘non-stop’ and as far as I know she is the oldest to make a non-stop circumnavigation.
Both voyages are praiseworthy.
I sent notification when I completed the GANNET circumnavigation only to CRUISING WORLD, LATITUDE 38, and Sailing Anarchy, all of which had shown interest in the voyage and asked me to.
I do not seek or need validation from others.
GANNET and I were meet by a crowd of three, which was three more than I expected.
Long ago I was in the GUINNESS BOOK OF WORLD RECORDS for my first circumnavigation. I did not contact them. They somehow heard of the voyage and contacted me.
