Owning a boat is a significant investment, and protecting it from environmental damage is a priority for every boat owner. Harsh weather, UV radiation, dirt, debris, and even rodents can wreak havoc on a vessel during off-season storage or overland transport. One popular solution is shrink wrapping, a process that encases a boat in a tight, protective plastic film. However, shrink wrapping comes with a recurring cost that can range from moderate to substantial, depending on various factors. This article explores whether boat shrink wrapping is worth the expense by examining its benefits, drawbacks, alternatives, and cost considerations. We’ll also provide detailed insights to help you decide if shrink wrapping aligns with your boat’s needs and budget.
What Is Boat Shrink Wrapping?
Shrink wrapping involves covering a boat with a sheet of low-density polyethylene (LDPE) film, which is then heated to shrink tightly around the vessel’s contours. The result is a custom-fit, waterproof barrier that protects the boat from external elements. Typically, the wrap extends slightly below the rub rail or further down the hull, ensuring comprehensive coverage. Shrink wrapping is most commonly used for:
- Winter storage: Protecting boats stored out of the water during cold months.
- Overland transport: Shielding boats from road debris, wind, and weather during transit.
LDPE is favored for its durability, UV resistance, and ability to form a taut, impermeable seal. The process, while effective, requires precision and is often performed by professionals, though some boat owners opt for a DIY approach.
The Shrink Wrapping Process
Shrink wrapping is a multi-step process that demands careful execution to avoid damage and ensure proper protection. Below is an overview of the key steps:
- Winterization (if applicable): Before wrapping, engines and plumbing must be winterized to prevent damage from freezing temperatures.
- Build a Support Structure: A grid of poles (typically 2x4s) and webbed strapping is erected along the boat’s centerline at approximately 4-foot intervals. The structure ensures the wrap doesn’t sag and supports the film’s weight.
- Cut and Drape the Film: The LDPE film is cut to size, unfolded, and draped over the support grid, covering the boat’s surface.
- Heat Application: Using a propane-fired heat gun, the film is heated to shrink tightly around the boat. A tunnel-like hem is created along the hull, containing a drawstring line to secure the wrap.
- Sealing and Finishing: Excess film is folded, sealed with shrink-wrap tape, and heated to ensure a snug fit. Vents and zippered doors are installed for ventilation and access.
While DIY shrink wrapping is possible, it’s labor-intensive and risky, especially for larger boats. Professional services are often recommended for consistent results.
Benefits of Shrink Wrapping
Shrink wrapping offers several advantages that make it a popular choice for boat protection. Below are the primary benefits:
Superior Weather Protection
Shrink wrapping provides exceptional defense against harsh weather conditions, including rain, snow, ice, and wind. The tight, waterproof seal prevents moisture from seeping into the boat, reducing the risk of structural damage, rust, or corrosion. This is particularly critical in regions with severe winters, where prolonged exposure to snow and ice can degrade a boat’s materials.
UV Resistance
Unlike many traditional covers, shrink wrap offers robust UV protection, shielding the boat’s finish from sun damage. Prolonged UV exposure can cause fading, cracking, or discoloration of gel coats and paint. Shrink wrap’s UV-resistant properties help maintain the boat’s aesthetic and structural integrity.
Custom Fit and Secure Seal
The shrink-wrapping process creates a tailored fit that conforms to the boat’s unique shape. This minimizes low spots where water or snow could pool, a common issue with tarps or fabric covers. The secure seal also deters rodents and pests, which can nest in uncovered or loosely covered boats during storage.
Transport Durability
For boats being transported overland, shrink wrap acts as a robust barrier against road debris, wind, and weather. A specialized “bullet wrap” made of heavier-duty material is available for trailered boats, ensuring the cover withstands highway conditions.
Drawbacks of Shrink Wrapping
Despite its benefits, shrink wrapping has notable downsides that boat owners must consider. These include cost, potential risks, and environmental concerns.
Cost of Shrink Wrapping
Shrink wrapping is a recurring expense, as the plastic film is typically single-use and must be replaced annually. Costs vary based on boat size, location, and additional features. Below is a breakdown of average costs:
| Boat Type/Size | Cost per Foot | Additional Costs |
|---|---|---|
| Powerboats (20–30 ft) | $12–$18 | Entrance: $30–$40, Vents: $4 each |
| Powerboats (30–50 ft) | $18–$25 | Anti-moisture bags: $8 each |
| Sailboats (20–30 ft) | $12–$18 | Mast up: +$2–$3 per foot |
| Sailboats (30–50 ft) | $18–$25 | Anti-mold spray: $50 |
| In-water wrapping | +$100–$150 | |
| Larger boats (>50 ft) | Custom quote | Tuna towers, flybridges: Custom pricing |
For example, shrink wrapping a 30-foot powerboat might cost $540–$750, while a 50-foot sailboat with a mast could exceed $1,400. Additional features like vents or entrances increase the total.
DIY Costs: DIY shrink wrapping requires purchasing materials and tools, including:
- LDPE film: $200–$400 for a 30-foot boat.
- Heat gun: $300–$500.
- Propane: $25–$70.
