Strapping Options For Shrink Wrapping Your Boat

When it comes to boats, shrink wrapping is a common method used for protection during storage, transportation, or periods of inactivity. This process involves using heat to shrink a protective covering, typically made of polyethylene, tightly around the boat's structure. To effectively strap and secure the shrink wrap, various materials and techniques are employed.

One essential component is the use of strapping systems, which can be made from materials such as polyester or cross-woven poly straps. These straps are tied or buckled to create a stable frame for the shrink wrap to drape over. It is important to ensure that the straps are tight and secure, as loose straps can result in a loose wrap. Additionally, heat-resistant gloves and safety gear are recommended when working with heat tools to avoid any accidents.

When installing the shrink wrap, it is crucial to start by selecting the right size for your boat and thoroughly cleaning and drying the boat's surface. The wrap is then unrolled and spread over the boat, with excess material cut and secured using strapping or adhesive tape. The heat application process follows, starting from the bottom and working upwards, ensuring a snug fit.

To ensure optimal protection, ventilation ports are also necessary to prevent moisture buildup. Regular inspections and maintenance of the shrink wrap are important to address any tears or loose areas. While shrink wrapping a boat with the mast up can be challenging, it is possible by cutting and sealing the wrap around the rigging.

Poly-woven strapping cord

When shrink-wrapping a boat, the strapping cord should be tight and secure to create a stable frame. Poly-woven strapping cord can be purchased in various widths, such as 1/4 inch, 3/8 inch, 1/2 inch, 5/8 inch, and 3/4 inch, to accommodate different boat sizes and requirements. It is important to measure the boat's dimensions accurately to determine the correct amount of strapping cord needed.

To install the poly-woven strapping cord, run the cord through the loops or cleats along the boat's edges and tighten it using a tensioning tool. This creates a perimeter band that keeps the shrink wrap in place. The cord can then be secured using buckles or by tying it firmly.

In addition to its functional benefits, poly-woven strapping cord is also customisable. It can be colour-coded and printed on, allowing for easy identification and a professional appearance. Overall, poly-woven strapping cord is a reliable and effective solution for shrink-wrapping boats, providing the necessary strength, flexibility, and durability to protect boats during storage or transportation.

Crosswoven poly strapping

When using crosswoven poly strapping, it is important to consider the width and length of the strap. For boats, it is generally recommended to use a width of 1/2" or 3/4", with varying lengths available for both options. A heavier-duty 3/4" strap is also available for more demanding tasks, such as load-bearing and high-tension scenarios like a boat's centre and perimeter straps in shrink-wrapping.

The tensile strength of the strapping is also an important factor to consider. A higher tensile strength will provide greater durability and resistance to fraying. Additionally, a lightweight coating on the strapping can further enhance its toughness and rigidity.

When installing crosswoven poly strapping, it can be held in place using hand-tied knots. For more tension, a self-locking metal buckle and tensioning tool can be used. It is important to keep a safe distance from the strap when applying heat with a heat gun, as the strapping can easily melt under intense, direct heat.

Propane heat gun

When it comes to shrink wrapping a boat, a propane heat gun is an essential tool. Here's a detailed guide on the use of propane heat guns in the shrink-wrapping process:

Choosing the Right Propane Heat Gun

Preparing the Boat

Before using the heat gun, ensure you've followed the necessary steps to prepare your boat for shrink wrapping. This includes moving the boat to a well-ventilated area, covering sharp edges, and building a support structure with strapping. It's crucial to work in a safe environment, so keep flammable materials away, and consider wearing protective gear like heat-resistant gloves and safety glasses.

Using the Propane Heat Gun

Once your boat is prepared, you can start using the propane heat gun. The heat gun will help you weld the shrink wrap to the boat's perimeter band, creating a tight seal. Start by heating the edge of the shrink wrap lightly, working your way around the boat. Remember to wear heat-resistant gloves to protect your hands.

Shrinking the Wrap

After securing the wrap to the perimeter band, it's time to shrink the wrap. Hold the heat gun about 6 inches above the boat and move it steadily from the back to the front, heating the sheeting evenly. Work on one side of the boat at a time, and use gentle, even strokes to avoid damaging the wrap. You can use a ladder or an extension tool to reach the top parts of the boat.

Finishing Touches

Once you've shrunk the wrap, you can finish the process by taping over any holes or weak points in the wrap. Use shrink wrap tape to reinforce the seams and create a stable, sealed wrap. Finally, install vents to allow for airflow and prevent moisture buildup during storage.

Maintenance and Safety

Remember to maintain your propane heat gun and follow safety precautions. Keep a fire extinguisher nearby as a safety precaution when working with heat tools. Additionally, ensure you have the necessary accessories, such as hoses, propane quick connections, and a full propane tank.

By following these steps and using a propane heat gun effectively, you can successfully shrink wrap your boat, protecting it during storage or transportation.

Buckles and tensioning tools

When shrink-wrapping a boat, it is important to use different-sized strapping for different applications. For the centre strap, which creates a peak and forms the highest part of the structure, use 3/4-inch strapping. This is the greatest load-bearing strap and should be installed first. Feed the strap through a metal buckle and tighten it by hand. Then, use a tensioning tool to further tighten the strap to your desired tension.

For the parts of the structure on the top and for belly bands, use 1/2-inch strapping. Belly bands are important to secure to avoid cresting of the shrink wrap, which can lead to spots on the boat that are exposed to sunlight and may cause uneven weathering. Place the belly bands 3-5 feet apart on boats and secure them with a buckle. Then, use a tensioning tool to tighten the strap at the buckle.

When using a tensioning tool, be careful not to damage the boat or bend the metal buckle. It is also important to cover any sharp points of the buckle with preservation tape to prevent damage to the shrink wrap.

Heat-resistant gloves

When shrink wrapping a boat, it is important to wear heat-resistant gloves to protect your hands from the heat gun. Heat-resistant gloves are part of a Shrink Wrap Accessories Kit, which also includes woven strapping tape, strapping buckles, and shrink-wrap self-adhesive vents.

The heat gun is used to weld the shrink wrap to the perimeter band, and to shrink the wrap by applying even strokes. It is important to be careful when using the heat gun, as the wrap can be damaged by overheating. A heat-resistant glove will protect your hands from the heat, but it is also recommended to keep a fire extinguisher nearby, just in case.

There are different types of heat-resistant gloves available, such as leather gloves and flame-resistant gloves. It is important to choose gloves that offer adequate protection, as the heat gun can get very hot. In addition to gloves, it is also recommended to wear safety glasses to protect your eyes from the heat and any debris that may be generated during the shrink-wrapping process.

When purchasing heat-resistant gloves, it is important to consider the size, material, and temperature rating to ensure they provide the necessary protection. They should fit comfortably but not too tightly, as this could restrict movement and dexterity. It is also important to choose gloves made from a material that can withstand the heat generated by the heat gun. Different materials have different temperature ratings, so it is crucial to select gloves with a rating that meets or exceeds the temperature of the heat gun.

In addition to wearing heat-resistant gloves, it is important to follow other safety precautions when using a heat gun. This includes working in a well-ventilated area, keeping flammable materials away from the work area, and regularly inspecting the heat gun for any damage. By taking these precautions and wearing the appropriate personal protective equipment, such as heat-resistant gloves, individuals can help ensure their safety when shrink-wrapping a boat.
