Shrink wrap is the best means of protecting your boat from the snow and ice during those long, cold, and windy winter months. Shrinkwrap cost is determined by the type,length, and winterization of your boat. If you winterize you boat with LSM you can get a discounted shrinkwrap price. Shrinkwrap for pontoon boats is $18/ft (w/ winterization) and $21/ft (w/o winterzation). For runabouts and PWCs the cost is $15/ft (w/ winterization) and $18 (w/o winterization). This cost includes mildew inhibitors and support structure.
