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.
