I just bought my first big boat (25 ft searay), used but in great condition. I live in St. Paul, Mn and will store it at the marina where I have a slip. My question is: It is kept outside and they will shrink rap it for $9 a foot. Would it be cheaper in the long run to have a winter cover custom made? What is the best material to use? How many years would the cover last? And will the cover protect the boat as good as a shrink rap? Thanks for any help.<br /> <br /> New_Sailor
