"You should also never paint a boat green thats bad luck as well."
Well... you don't want to believe all that hocus-pocus...The Transat Jacques Vabre has just been won by a green boat, which was the Fico champion last year as well ("Groupama"). Loic Peyron spent years winning just about every major race there is with a green boat ("Fujicolor")...and on a much more lowly level, my humble craft has a fair amount of green too and so far she's always looked after me...
"A boat should also be a she, bloke names aren't allowed."
In France, boats are masculine...ever hear of Bernard Moitessier and his boat "Joshua"?
And to continue this line of debate...I know a bloke who called his catamaran "Two Rabbits", painted it green and launched it on a Friday...still going well thousands and thousands of miles later...
