The KOHLHOFF Grand-prix furling line is endlessly spliced and has been developed after years of practical experience. The choice of Gottifredi Maffioli's Airswift and a high quality, seamless splice ensures no snagging or build up of the cover in the furling drum when under load. This is a continuous loop construction using 31m of Airswift 6.5mm line to make a total loop length of 15m. Loop length is recommended to be the distance from drum to primary/genoa winch plus approx 3m
