Along with it being unlucky to start a race or leave on a cruise on a Friday.

And recently there was some discussion in Scuttlebutt about whether it is unlucky for a boat to be painted green.

Speaking of which, did you notice the name of the filly that had to be euthanized after she came in second in the Kentucky Derby with two broken ankles. Her name was Eight Belles. That's close enough to Eight Bells for me to think it was not a lucky name. Eight Bells is a nautical euphemism for death when somebody in the sailing community dies, because 8 bells signal the end of a watch.
