Like the Facnor carbon furling systems on board of Jean Luc Van Den Heede's 80 footer, the Ls drum and swivel are fitted with a "bearing box" (see above). This was tested over ocean races under loads up to 20 to 30 times higher than a 30ft cruising boat. Even under high halyard tension furling remains easy. This innovative system is now available for every boat thanks to Facnor continuous development. If you need any assistance selecting the appropriate Facnor LS Jib Furler for your furler please contact us at Mauri Pro Sailing. Our crew is ready to help.
