It’s crucial to get accurate measurements to ensure that the shrink wrap will fit snugly and cover the entire boat.
  • Calculate the Needed Film Size: Once you have your measurements, calculate the size of shrink wrap film you’ll need. Add some extra length and width for overlapping and securing the seams. Most shrink wrap suppliers recommend adding at least 10% to your boat’s dimensions to account for these allowances.
  • Cut the Shrink Wrap Film: Lay out the shrink wrap film on a clean, flat surface, such as a driveway or boatyard. Use a sharp utility knife or scissors to cut the film to the calculated size. Ensure that your cuts are clean and straight to avoid any irregularities in the final wrap.
  • Account for Bow and Stern Shapes: If your pontoon boat has a bow or stern shape that differs from a simple rectangular box, you may need to create custom shapes or angles in the shrink wrap film to accommodate these features. Cut the film accordingly to ensure a tight fit around these areas.
  • Overlap and Secure Seams: Where two pieces of shrink wrap film meet, you’ll need to overlap them to create a secure seam. Use high-quality shrink wrap tape to bond the overlapping edges together. Make sure the seams are well-sealed to prevent wind or moisture from getting underneath.

Properly measuring and cutting the shrink wrap film is a critical step in the winterization process. Taking the time to get accurate measurements and clean cuts will result in a tight and secure wrap that effectively protects your pontoon boat during the winter months.

Process of Securing the Shrink Wrap to the Pontoon Boat

Securing the shrink wrap to your pontoon boat is a crucial step in the winterization process. Here’s a detailed guide on how to do it effectively:

Attach Strapping and Buckles: 

To keep the shrink wrap securely in place, you’ll need to use strapping and buckles. These should be threaded through reinforced holes or loops along the sides of the shrink wrap. Follow these steps:

  • Start at one end of the boat and work your way to the other.
  • Thread the strapping through the hole or loop on one side of the shrink wrap.
  • Bring the strapping under the boat and up to the opposite side.
  • Thread it through the corresponding hole or loop on the other side.
  • Pull the strapping tight, creating tension to hold the shrink wrap snugly against the boat.
  • Secure the strapping with the buckles, ensuring they are tight and won’t come undone.

Create Seams Using Heat: 

To make the shrink wrap film conform to the contours of your pontoon boat and create a tight, secure cover, you’ll need to use heat. Here’s how:

  • Start at the top of the boat and work your way down.
  • Use a heat gun or propane torch to carefully apply heat to the shrink wrap film. Move the heat source evenly back and forth to avoid overheating or melting the film.
  • As the film heats up, it will shrink and conform to the shape of your boat.
  • Pay special attention to seams and overlaps. Apply heat to these areas to create a strong bond between the film pieces.
  • Continue down the length of the boat until the entire shrink wrap is snug and secure.

Ensure a Snug and Secure Fit: 

Throughout the process of attaching strapping, buckles, and applying heat, regularly check the shrink wrap for any loose or sagging areas. The goal is to achieve a tight and secure fit with no flapping or air gaps. Use additional strapping and heat as needed to eliminate any slack.

Properly securing the shrink wrap is essential to protect your pontoon boat from winter weather, moisture, and pests. A snug and secure wrap will help preserve your boat’s condition until it’s ready to hit the water again in the spring.

Set Up Support Poles to Prevent Water and Snow Buildup on the Shrink Wrap

Installing support poles is a crucial step in shrink wrapping your pontoon boat to prevent the accumulation of water and snow on the cover. Here’s how to do it effectively:

Position Support Poles Strategically:

  • Start by selecting sturdy and appropriately sized support poles. These should be placed inside the shrink wrap to create a peak or slope on the cover, allowing rainwater and snow to run off.
  • Position the support poles at intervals along the length of the boat. Typically, one or two rows of poles may be needed, depending on the boat’s size and shape.
  • The poles should be evenly spaced to distribute the load of snow and prevent sagging in the cover. Place them strategically to form a gentle peak rather than a flat surface.

Ensure They Are Secure and at the Correct Height:

  • Once you’ve positioned the support poles, ensure that they are securely anchored. They should be placed on a stable surface within the boat, such as the deck or seats.
  • Adjust the height of the support poles to create a slight slope in the shrink wrap cover. The goal is to encourage water, snow, and debris to slide off the cover rather than accumulating on top.
  • Make sure the support poles are tall enough to provide adequate clearance for snow buildup. Generally, a height that allows for 12 to 18 inches of clearance above the boat’s surface is suitable.
  • Secure the poles in place, ensuring they won’t shift or collapse under the weight of snow or ice.

Properly installed support poles are essential for maintaining the integrity of your shrink wrap cover and preventing the formation of pockets where water and snow can collect. By creating a slight slope and securely anchoring the support poles, you’ll help protect your pontoon boat during the winter months.
