The British entry for the 1987 America's Cup was White Crusader. She was sponsored by Graham Walkers White Horse whisky.
I purchased this guernsey sweater many years ago and have only worn it 2 maybe 3 times.
It was made from british wool by Le Tricoteur, probably the best known maker of traditional Guerney sailing jumpers. 
It is in very good condition with no stains or holes and as it has been stored for so long the colours have not faded.
