My sailmaker says...
no problem. I raised the issue because I want the boat to be available on the occasional nice day oveer the winter. And removing and replacing the sails on a 37 foot boat IS a hassle. Have to find a windless day for one thing.Here is exactly what he wrote to me:"Sails should not be a problem. Mainsail covered, genoa furled. However, Iwould take a webbing strop and run it through the headsail clew and verytightly wrap the genoa a few times and tie the webbing off very securly.This will give you some added 'unfurling' protection should we have somenasty weather."The mainsail will be fine inside the cover...but it to should be firmlytied to the boom with ties...just in case."I have not done this before. I usually remove the sails and send them to the sailmaker for cleaning, repair and winter storage (better his closet than mine). But this year, since my insurance allows me to do it, I want to go sailing in the cold.To get back to the original question, there certainly seems no reason at all why the jib should not be left rolled on the furler, esopecially indoors. Indeed, I think it might well be better for it since it will not be folded, as it has to be to get it into the sailbag, and folding does more damage to materials than does rolling.
