fishermen in particular, have always been extremely superstitious (迷信的). This is
hardly surprising when one considers the changeable nature of the sea where,
even today with sophisticated weather-forecasting techniques a sudden storm can
blow up quite unexpectedly. In the days before radio and engines, where there
could be no long-distance communicating with another ship or land and when sails
were the only means of movement, it was only natural for the sailor to take
every precaution to avoid offending the gods who control the sea.
One way of pleasing these gods was to make an annual offering. This custom
survives in the ceremony of blessing the sea, which can still be seen once a
year in some fishing ports. Next to pleasing the sea-gods, the
most important thing for the sailor is to know that his boat is free from evil
influences. The time to make sure of this is at the launching ceremony. It is
clear that the well-known custom of launching a ship by breaking a bottle of
champagne against the side goes back a very long way. On the
North coast of Britain new ships are launched with sea-water, and on the
North-East coast of Scotland a similar ceremony takes place but with whisky
substituted for sea-water. In both cases, the launching is followed by drinking
and celebration. The purpose of these ceremonies is to keep away evil spirits,
rather than to ask for the sea-god’s protection. Starting on a
new voyage or fishing trip was a dangerous business at the best of time. Once
the fisherman has set out for his trip he dared not, on any account look back.
It was bad luck even to call after him, so if he had forgotten anything, someone
had to urn after him and put the object into his hands. But bad
luck could also result from some chance meeting on the way to the boats. In some
countries, it was considered particularly unlucky to meet a priest, a rabbit or
a woman. In such an event, the only thing to do was to turn back and sail next
day. Redheads and people with flat feet were also to be avoided,
but if the fisherman did happen to meet them, he could avert bad luck by
speaking to them first. For a fisherman to see a dog near his boat was unlucky,
while cats were considered lucky, especially black ones. Some fishermen’s wives
believed a black cat would bring their husbands back from the sea, and sometimes
domestic cats disappeared from island towns and turned up in fishing
villages! It is implied in the passage that superstitious practices stemmed from sailors and fishermen’s fear for the unreliability of nature.
