I bought a furler at the Strictly Sail show this weekend .I would like to have a reputable sailmaker that lives within 75 miles or so look at my sails to see which one would work best as far having it converted.What exactly is the differance between a jib and genoa ?What is a barber hauler and what is a screecher? Sorry but I only know one other person who sails and his explanations are very short .
