Your profile doesn't say what type/size of boat you have, but if you fold your sails, they take up very little space. If your boat is small, you might consider using the vee for storage and the quarter berth for sleeping.
When I crossed the Atlantic on a Swan 48, the owner had 13 extra sails aboard. It was all the storm sails and older sails that had been replaced by new sails, but where still in good condition. When I suggested he get rid of a few (or 10) of them, he was indignant! "Do you know how much they cost?" he yelled! And although we had every sort of
wind condition you could imagine, none of the storm sails or smaller headsails ever made an appearance on deck. We did set a spinnaker, a decade old but never even unfolded from the
sailmaker. The steadying affect on the boat was dramatic. And the
skipper insisted we keep it up, even when the
wind increased. We later filled the sailbag with the colourful scraps of sailcloth remaining after the sail exploded in a sudden squall.
