In 1977 we discussed what would happen if when hoisting the jib it jammed in the pre-feeder. I worked evenings after racing hand making one pre-feeder capable of being opened in the event there was jam. As with so many things once the season was over, I put it away. Preparing for the America’s Cup Jubilee in 2001 the question came up again. I still had my hand made proto-type. Jim Gubelmann, a good friend took an interest in it as a marketable product.
