We installed a new winter cover on our hunter 376 today. It is the type with a full frame of a spine and ribs. The cover comes in two pieces joining each other at the mast. Problem Is the top zipper from the mast down towards the shrouds at the toe rail can’t be zipped together as the lower spreader to lower mast shrouds are in the way. Manufacturer was closed today probably due to the holidays so couldn’t confirm if this is a mistake or should I just disconnect these shrouds and zip it up?
