L'etui de genois remplace la bande sacrificielle cousue sur les chutes et bordures des voiles d'avant, necessaire pour proteger les voiles des rayons ultra violet.

Elle se hisse avec la drisse de spinnaker, et protege la voile enroulee du soleil, des intemperies et de la pollution.

“I got one. It was only $300 something and a new genoa for my boat starts at well over $1000. I don't believe in roller reefing, only furling. I have four headsails and none of them have sun covers. When I race the boat, I put up the most appropriate sail but I use the furler as designed rather than in “race mode” without the drum. At the windward mark I furl it and raise the chute, makes for easier foredeck work. When I'm done and want to scoot my butt on up to the club, I furl the jib, put on the cover and jet. Covers for all my sails would be much more than $300 and I don't have to put up with the overstuffed bra shape you get with the suncovered sails. This one is only a little more than the basic sleeve models sold by sailrite and others and it has one major advantage, it has a drawstring arrangement that allows you to snug it up around the sail after you put it on so it doesn't flap in the wind. It also keeps your spin halyard clean since all but the last little bit is inside the mast. Of course if a storm is coming or if I'm not going to be sailing the boat for a week or two, I take the sails off and bag them. Really going to be nice for extended cruising because you can leave the sail on all the time and not kill it with UV. That's one less sailbag I have find a spot for while cruising.”
