What do you all mean by 120, 150% etc. As a kid in sea explorer scouts we had a working jib, a storm jib that was not much bigger than a peacoat and a genoa. Does anyone have any imformation on the HOYT jib boom, I've been told by someone at the yard that it increases the efficiency of the head sail; although, the person who told me that, I never have seen him take his boat out in two years.
