In view of Stan’s apparent knowledge, I delegated the pilotage to him and, stupidly, didn’t keep an eye on the charts and the marks although I had read up on the passage. At that stage we did not have a chart plotter so we were relying on paper charts and eyeball navigation in very clear visibility.

It would be prudent for all navigators on unfamiliar boats, or perhaps when returning after a period of time to a familiar boat, to ensure that the hidden, potentially helpful fudge factors buried in silicon memories are actually helping, not hurting, your navigational accuracy
