Extra low stretch yacht braid. 5/16″ X 66′ for most boats. The genoa sheet, when in use on a roller furling boat can be very pretty a color other than white. White is shown and is standard. White with blue or black ticking depending on availability. Consider solid blue, green, or red. An upgraded solid color line is easy to call out to be released. This line is a single line for both sides, meaning you find the middle and pull the middle through the ring then put the rest of the line through itself to make one for each side.
