What You'll Learn
Recognising when a winch strap needs replacing
- Frayed stitching, tears, cuts, or extreme fading: These are all indications of an ailing winch strap. Sun exposure, moisture, misuse, or simply old age can cause the winch strap to deteriorate over time.
- Visible damage: If your winch strap is fraying or showing other signs of wear and tear, it's likely that its structural integrity is compromised.
- Old age: If you're unsure how old your winch strap is, it might be a good idea to replace it. Older straps may be more prone to failure due to weakened materials.
- Deteriorating hook: Even if the strap itself appears intact, a deteriorating hook can be a sign that the entire assembly needs to be replaced.
- Loose or weakened threads, tears, or loose threads around the hook: Inspect your winch strap regularly for any signs of wear, including loose or weakened threads and tears.
- Abrasions and creases: Normal use, such as boat ramp activities or improper winding, can cause abrasions and creases in the winch strap. These can weaken the webbing over time.
- Coiling the strap while wet: If you regularly coil the winch strap while it's still wet, this can eventually weaken the threads used to sew on the hook.
It's important to note that winch straps are typically very durable and can last for many years, even decades, with proper care and maintenance. However, if you notice any of the above signs of deterioration, it's best to replace the winch strap promptly to ensure the safety of your boat and those using it.

Tools required for the job
Replacing a boat winch strap is a simple process that can be done with just a few tools. The tools you will need include:
- Wrenches: You will need box wrenches to remove the winch gear bolts and anchor bolt.
- Sockets: These will be used alongside the wrenches for removing bolts.
- Screwdrivers (depending on the design of your winch): You may need a screwdriver to remove outside pieces of the winch to access where the strap connects.
- Utility knife or box cutter: A sharp knife will be useful for cutting off old webbing or an old strap if necessary.
- Thread lock: If your winch uses a bolt passing through the drum-end of the strap, you will need thread lock to secure it.
- Marine grease or lubricant: Applying a small amount of grease or lubricant to the winch gears will ensure they turn smoothly.
In addition to these tools, you will also need a replacement winch strap that is compatible with your winch and rated for the weight of your boat. It is important to choose a strap with a strength rating at or above that of the winch and ensure it is the correct width, length, and load capacity for your boat and winch.

Choosing the correct winch strap for your boat
Resistance and Durability:
Look for a winch strap that offers maximum tensile strength with minimum stretch. It should be able to support heavy loads without damage. The hook should also be very resistant to withstand the weight of the boat. Opt for a strap that is made from durable materials that can resist environmental factors, mildew, and other agents that can cause damage over time.
Working Load Capacity:
Determine the working load capacity of your winch by checking the manufacturer's specifications or looking for a stamp on the winch itself. Choose a winch strap with a strength rating at or above the working load capacity of the winch. Ensure that both the strap and winch are rated for the weight of your boat.
Webbing-Type vs. Rope or Cable:
Confirm whether your winch is designed for a webbing-type strap or a rope/cable. Webbing-strap winches typically have a drum width of 2 inches or wider and a drum diameter of less than 13/4 inches. They also have a bolt or holes for one that goes through both sides of the spool adjacent to the drum. Winches designed for rope will have a single hole on the side of the spool, while those for cable will usually have a drum diameter of at least 13/4 inches and may be narrower than 2 inches.
Length and Width:
Select a winch strap with sufficient length and width to accommodate your boat's size and weight. Most winch straps range from 20 to 32 feet in length and 2 inches in width.
Breaking Strength:
Consider the breaking strength of the winch strap, which indicates the maximum weight it can handle before failure. Choose a strap with a breaking strength that exceeds the weight of your boat.
Compatibility:
Ensure that the winch strap you choose is compatible with your winch type (manual or electric) and fits securely on the winch drum.
Material:
Opt for a winch strap made from high-quality, durable materials such as heavy-duty polyester or poly/silk webbing. These materials can withstand harsh marine environments, including saltwater exposure, UV damage, and water exposure.
Brand Reputation:
Consider purchasing a winch strap from a reputable brand known for producing high-quality, durable products. Reading reviews from other boat owners can also help you make an informed decision.
Remember, safety should always be a priority when selecting a winch strap for your boat. By considering these factors, you can choose the correct winch strap that will provide secure and hassle-free loading and unloading of your boat.

Removing the old winch strap
Firstly, you will need to gather the required tools. For this task, you will need box wrenches to loosen and remove the locknut and anchor bolt holding the strap in place. Additionally, a utility knife may come in handy if you need to cut through the old strap. Before beginning, ensure you are wearing appropriate protective gear, such as gloves and eye protection, to prevent any injuries.
Once you have the necessary tools, start by unwinding the old strap from the winch drum. Depending on the condition of the strap, you may need to cut it off the bolt to access and inspect the anchor bolt. If the anchor bolt is damaged or worn, it is recommended to replace it with a new one. Use the box wrenches to loosen the locknut that secures the strap's anchor bolt to the drum. You may need to apply some force to loosen the locknut, especially if it has not been removed in a while. Once the locknut is loose, remove it and set it aside, along with the anchor bolt, if necessary.
At this point, the old winch strap should be completely free, and you can dispose of it appropriately. Be sure to handle the old strap with care, as it may have sharp edges or frayed pieces that could cause injury. It is also important to note that you should not reuse the old strap, even if it appears to be in decent condition. Reusing an old strap can compromise the safety and integrity of your boat's winch system.
Now that the old strap has been removed, take the opportunity to clean and inspect the winch drum and surrounding components. Look for any signs of corrosion, damage, or wear that could affect the performance or safety of your winch. If you notice any issues, address them before installing the new winch strap.
By following these steps, you can safely and effectively remove the old winch strap from your boat, preparing it for the installation of a new strap. Remember to work slowly, use the appropriate tools, and prioritize your safety throughout the process.

Attaching the new winch strap
To attach the new winch strap, you will need a new strap, box wrenches, and possibly a new anchor bolt and nut.
First, check that you have purchased the correct strap for your winch. Ensure that the strap's strength rating is at or above that of the winch and that both are rated for the weight of the boat. Confirm that your winch is designed for a webbing-type strap, which will have a drum width of 2 inches or wider and a drum diameter of less than 1 3/4 inches.
Once you have confirmed that you have the correct strap, follow these steps:
- Insert the bolt through the spool wall, through the loop sewn into the end of the new strap, and out through the opposite hole in the spool wall.
- Attach and tighten the locknut onto the bolt, ensuring that it is secure without overtightening it against the spool.
- Wind the new strap onto the winch drum, ensuring that it lies flat and is free of any twists, creases, or folds.
- Snap the hook on the new strap to the boat's bow eye.
By following these steps, you can securely attach the new winch strap to your boat trailer, ensuring a safe and reliable connection between your boat and the trailer.
