Boat Shrink Wrap and Supplies
Boat shrink wrap is heat-shrinkable plastic sheeting used to cover boats for seasonal storage and transport. It forms a close-fitting cover that helps protect exposed surfaces from water, airborne debris, and grime. When choosing supplies, consider your boat’s size, storage environment, and the equipment needed for installation and ventilation.
Shrink Wrap Compared with Tarps and Canvas
Polyethylene tarps and canvas covers are other options for boat storage. Shrink wrap forms a closer-fitting cover when heated. Canvas covers are often significantly more expensive, while tarps may flap in the wind or collect water and snow if they are not supported by a rigid frame.
Why Choose Shrink Wrap for Your Boat?
Boat shrink wrap is thin plastic sheeting that tightens when heated, forming a custom-fit cover around the hull and deck. It is commonly used for winter storage and to protect new boats during shipment from manufacturers.
Benefits of Boat Shrink Wrap
- Durability: Designed to handle demanding winter conditions with minimal maintenance.
- Close fit: Heat shrinking creates a tight cover that helps block water, dirt, and debris.
- UV resistance: Many materials include UV inhibitors to slow sun-related degradation.
- Seasonal handling: The cover can be installed and removed for seasonal storage.
Types of Boat Shrink Wrap Supplies

How to Shrink Wrap Your Boat
Materials Needed
- Boat shrink wrap
- Heat gun
- Shrink-wrap tape
- Vent covers
- Strapping and buckles
- A-frame support made from wood or metal tubing
- Strap-tensioning tool and high-strength woven cord strapping
- Perimeter padding and heat-resistant safety gloves
Steps to Shrink Wrap Your Boat
- Prepare: Clean and dry the boat, and remove items sensitive to heat or moisture.
- Cover: Drape the shrink wrap to protect exposed surfaces.
- Secure: Strap the material firmly around the hull.
- Heat: Shrink the perimeter band (belt) first to lock in tension, then shrink from the top down working from the ridgepole downward for even tautness.
- Ventilate: Install vents to help reduce moisture buildup.

Frequently Asked Questions
Why is shrink wrap commonly used for winter boat storage?
Shrink wrap forms a close-fitting cover that helps protect boats from water, dirt, and debris during extended storage.
What materials are needed to shrink wrap a boat?
The process requires shrink wrap, a heat gun, tape, vents, strapping with buckles, and an A-frame support structure.
Is boat shrink wrap environmentally friendly?
Standard shrink wrap is made from non-biodegradable polyethylene. Recyclable options and regional recycling programs may be available.
Can shrink wrap damage a boat’s finish?
When applied correctly, shrink wrap does not damage finishes or paint. Avoid using it on freshly painted or wooden boats.
How do I choose the correct mil thickness for my boat shrink wrap?
Thickness is typically determined by the storage environment and boat size. For most recreational boats in areas with moderate snow and wind, 7-mil is described as the industry standard. 6-mil is generally used for smaller boats or items in temperate climates, while 8-mil to 10-mil thicknesses are recommended for larger boats, high-wind regions, or heavy snow-load conditions to help prevent puncturing and collapsing.
What is the difference between white, blue, and clear shrink wrap?
White reflects heat and is described as helping maintain a stable temperature under the cover to minimize condensation. Blue absorbs heat and is preferred in heavy snow-load areas to help snow and ice melt and slide off. Clear wrap is primarily used for brokerage boats or “live-aboards” when interior visibility or natural light is needed; it requires extra attention to ventilation because of heat buildup.
How do I prevent mold and mildew from forming under the wrap during winter?
Proper ventilation and moisture absorbers can help reduce moisture buildup. Install self-adhesive vents, ideally in a high-and-low configuration to promote cross-flow, and place desiccant bags or moisture-control buckets inside the boat.
Can I use a standard heavy-duty tarp instead of shrink wrap?
A 10-mil heavy-duty polyethylene tarp is a budget-friendly option, but it does not form the same close-fitting cover as shrink wrap. Tarps can flap in the wind and cause surface abrasion on the hull. They may also collect water or snow in pockets if they are not supported by a rigid frame.
What essential tools are needed to shrink wrap a boat myself?
Along with the wrap, you will need a propane-fired heat tool, a strap-tensioning tool, and high-strength woven cord strapping to create the support structure. Accessories include shrink-wrap tape for seams and patches, perimeter padding to protect sharp corners, adhesive vents, and heat-resistant safety gloves.
