I will be having my E29 set up for winter storage. Can I safely leave the mast and Harken Roller Furling up during storage. The yard said the mast should be untepped or it may cause gelcoat damage (Stress). But I see many sailboats stored for winter with the mast up. The cost take it down and re-rig it is significant, am I making a mistake by leaving it up? The boat is stored on Eastern Long Island, NY. Thanks in advance for any advice. Bob Jasensky
