We used the John Vigor ceremony when we renamed one of our boats. I am not superstitious but shortly after changing the name we had the top plastic bushing break on the
head sail
roller furler, and the
furler tube chewed into the forestay. Had to haul the
boat and replace the stay and section of the
furling tube. Almost couldnt get the
head sail down off the tube. I don't remember any other "back luck" incidents like that. Probably just a coincidence.
