Winterizing your boat is vital to protecting the value of your boat and its condition. Most insurance companies won't cover damage due to freezing or neglect. As boat owners know, a cracked hull or engine is very expensive to fix. If you can't keep your boat covered in a climate-controlled storage area, it is very wise to have your boat shrink-wrapped, which gives a good layer of protection.
Come next spring when you start getting your boat ready for the season, you will be very glad you spent a little time and money to keep your boat in prime condition.
