the reason for the bad voodoo, is back in the day when ships would carry banannas back to europe, when a ship would go down all that would be floating after wards where bananas. also when they picked the bananas they didn't look thru them, unfortunetely. because there is a spider called a bananna spider...now i have been shot at, blown up and drank the water in tijauna, but them damn things are big and nasty and scare me more then the afforementioned things.

so hence the superstitions.
here are a few others;it is bad luck to set sail on a friday(its the day christ was crucified)
if a sailor hears church bells at sea then the ship is doomed
dolphins following a ship will protect the ship and its crew
a wrenns feather, plucked on new years day and worn in a single braid constitutes a sailors luck and prosperity
