What You'll Learn
Choosing the right rope
When choosing the right rope for a boat bumper, there are several factors to consider, including the type of rope, its length, thickness, and material.
Firstly, the type of rope is important. A braided rope is a good option for boat bumpers as it is strong and durable. Braided ropes are also easy to work with and can be tied securely. When selecting a braided rope, look for options made from nylon or marine-grade black premium nylon, which are strong and UV-resistant. Alternatively, you may consider using a solid braid multifilament polypropylene (MFP) rope, which is also suitable for boat bumpers.
Secondly, the length of the rope should be appropriate for your boat's size and the intended use. For example, if you require a rope for docking, ensure it is long enough to reach the dock comfortably. Standard lengths for boat bumper ropes typically range from 5 to 10 feet.
Thirdly, consider the thickness of the rope. Boat bumper ropes commonly have a thickness of 3/8 inch to 1/2 inch in diameter. The thickness you choose will depend on the size and weight of your boat, as well as the intended use. Thicker ropes can provide more cushioning and protection, while thinner ropes may be more manageable and suitable for smaller boats.
Lastly, the material of the rope is an important consideration. Nylon is a popular choice for boat bumper ropes due to its strength and durability. It is also resistant to saltwater and UV radiation, making it suitable for extended use outdoors. Other materials such as hemp or manila rope are more traditional options that can also hold up well to sunlight.
When purchasing a boat bumper rope, it is essential to consider the specific requirements of your boat, including its size, weight, and intended use. Additionally, ensure that the rope is of sufficient quality and strength to provide effective cushioning and protection for your boat.

How to tie a rope to a fender
To put a rope bumper around a boat, you'll need to tie a rope to a fender (or a "fender line") and then tie the fender line to your boat. Here's a detailed, step-by-step guide on how to tie a rope to a fender:
Step 1: Choose the Right Rope
Select a rope that is durable and can withstand the elements. Common materials include nylon, polypropylene, or hemp/manilla rope. The length of the rope will depend on the size of your boat and how you plan to use the fenders. For smaller boats, 15 feet of rope should be sufficient.
Step 2: Prepare the Rope
Using a sharp knife, cut the rope to the desired length. If needed, use whipping twine to bind the rope together securely. You can also use strong twine or a tent stake to tightly bind the rope. Leave a loop at one end, which will be used to hang the fender.
Step 3: Form the Crowns
Unlay the rope to create six strands. You can use tape or twine to manage the strands and make them easier to work with. Form a small open loop with one of the strands, with the "elbow" pointing left. Then, take the next strand and bring it in front of the previous strand, creating a "cradle." Repeat this process, moving from left to right, until you have a complete crown. Pull the strands tight to secure the crown.
Step 4: Secure the Ends
Continue adding crowns, working down the rope, until you reach the desired length for your fender. When you're finished adding crowns, you'll need to secure the ends of the rope. Use a fid or marlin spike to pry open the loops and then tuck the ends into the loops. You can also use a large tent stake if you don't have a fid. Repeat this process for all ends, and consider adding an additional layer of crowns for a stronger fender.
Once you've tied the rope to the fender securely, you can move on to the next step of attaching the fenders to your boat.

How to tie a fender line to a boat
To put a rope bumper around a boat, you need to tie a fender line to your boat. This process involves two steps: tying a rope to a fender and then tying the fender line to your boat. Here is a detailed, step-by-step guide on how to tie a fender line to a boat:
Tying a Rope to a Fender:
First, you need to tie a rope to a fender, also known as a fender line. A good knot to use for this is the bowline, as it is strong, creates a loop that will go through the eye of the fender, and can be easily untied if needed.
Tying the Fender Line to Your Boat:
Once you have securely attached the rope to the fender, you are ready to tie the fender line to your boat. This step is done every time you dock your boat. A recommended knot for this step is the clove hitch, as it is ideal for powerboats and can slide along the railing for last-minute adjustments.
If you are tying the fender line to a cleat on your boat or dock, a simple cleat hitch will also work. This type of knot is easy to put on and take off, even when under significant load or when the line is stiff from saltwater.
For sailboats, it is best to tie the fender line to the bottom of the stanchions where the railing is strongest and has a lower leverage point.
Additionally, consider the height at which you hang the fender, adjusting it based on the dock or piling you are working with. With floating docks, it is recommended to tie the fenders just above the waterline.
By following these steps and considerations, you can effectively tie a fender line to your boat, providing a cushion and protection for your boat when docking.

Determining the placement of the rope bumper
Understanding the Purpose of Rope Bumpers
Before placing your rope bumper, it's important to understand its purpose. Rope bumpers, also known as boat fenders, are essential devices that provide a cushion between your boat and other objects such as docks, jetties, or other boats. They help prevent damage to the paint, varnish, gunwales, and hull of your boat during docking or when moored next to another vessel.
Factors Affecting Placement
When determining the placement of your rope bumper, consider these factors:
- Size of the Boat: The size of your boat will dictate the placement of the rope bumpers. Generally, smaller boats will require less length and diameter in the fender. However, ensure that the fender is not too small, as it may not provide adequate protection and could get smashed if attached to a larger boat.
- Widest Part of the Hull: Place the rope bumpers along the widest part of the hull, as this area is most likely to come into contact with the dock or another boat. This ensures that the rope bumper effectively cushions any impact and prevents damage.
- Docking Configuration: Consider how you typically dock your boat. If you dock with only your bow next to a jetty, concentrate the placement of rope bumpers in this area. On the other hand, if you often back into a slip, you may need a rope bumper at the transom to avoid collisions with the dock.
- Height of the Fender: The height at which you hang the rope bumper depends on the type of dock you frequent. With fixed docks, pay attention to the tide to avoid positioning the fender too high or too low, which could be dangerous for your boat. For floating docks, it's generally recommended to tie the rope bumpers just above the waterline.
- Number of Fenders: The number of rope bumpers you need will depend on the size of your boat and your specific docking requirements. As a general guideline, most boats will require two to four fenders per side. Additionally, consider having an extra fender, known as a "roving fender," that can be placed wherever needed at the last minute.
Placement Techniques
Now that you understand the factors affecting placement, here are some specific techniques to help you position your rope bumpers effectively:
- Equal Spacing: While some boaters prefer to space their fenders equally along the hull, this may not always provide the best protection. Instead, focus on placing them along the widest part of the hull, as mentioned earlier.
- Adjusting Height: When tying the rope bumpers, consider the height of the dock or piling you typically work with. Adjust the height of the rope bumper accordingly to ensure it aligns with the potential point of impact.
- Circling for Adjustment: If you need time to adjust your rope bumper setup, don't be afraid to circle your boat a few times until you're ready to dock. This is a common practice and can help you achieve the perfect placement.
- Consider Hull Curvature: If you have a boat with less hull curvature, such as a catamaran, adjust the placement of the rope bumpers accordingly. These boats can touch farther down, closer to the waterline, so make sure the rope bumpers are positioned correctly to provide adequate protection.
By following these guidelines and techniques, you'll be able to determine the optimal placement for your rope bumpers, ensuring the safety and protection of your boat during docking and mooring maneuvers.

How to attach a tow rope to a boat
Learning how to attach a tow rope to a boat is a skill all ski and wakeboard boat owners must develop and master. Tying a tow rope in the wrong spot increases the risk of boat damage and injury to skiers and wakeboarders if it comes undone. Here is a step-by-step guide to attaching a tow rope to a boat:
Step 1: Choose the Most Appropriate Spot for Attaching a Tow Rope
Analyze your boat and look for sturdy sections to hold the tow cord. The spot should be secure and with ample space for tow rope movement. Some boats come with ski eyelets to attach the ski rope. You can thread the tow cord through the ski eye and secure it. However, this setup is not ideal for tubing as it is too high. Alternatively, you can tie down the tow ropes from the ski eyelet attachments to distribute pressure evenly behind the tow vessel. For optimum safety, you can install a designated tow bar.
Step 2: Select a Method for Connecting the Rope to the Tube and the Line to the Boat
Instead of using knots to secure the inner tube to the boat, many boaters use "wraps." Knots can be challenging to undo, especially for those unfamiliar with them, and they can increase the risk of tow cord damage. While most tubing enthusiasts use wraps, a slip knot is also a good option, especially in vessels with single or few attachment points. To execute a slip knot:
- Grab the cord and make a loop, ensuring the short end is nearly parallel to the long strand.
- Move the free end over the doubled lines and slip it through the resulting loop.
- Turn the free end over the doubled lines twice more, passing through the loop each time.
- Pull the free end to tighten.
You can also use other knots like a bowline, sliding hitch, or two-half hitches.
Step 3: Attach the Tow Rope to the Tubing
Gather your tow cord connector, tow rope, and tubing. Inspect each component for any defects. Hold the tube's webbing and insert the loop. Grab the quick-connect tow cord connector mechanism and insert it through the loop or eye. Pull the rope to tighten the knot and secure the setup. Connect the tow cord to the connector mechanism, ensuring a secure fit. If you don't have a connector mechanism, you can use one of the knots mentioned in Step 2.
Step 4: Secure the Tow Cord to the Boat
One effective way to secure the tow cord is to connect it to the tow ring at the vessel's transom. If your boat doesn't have a tow ring, you can secure the tow cord at the watercraft's tow bar or the side cleats. Ensure that the tube weight will not cause any harm to the transom or any other part of the boat. Check the transom weight capacity, and make sure it's larger than the tube's total weight. Another common practice is to tow the tube from the transom eye, which is popular for its simplicity.
Small boats often use a tow harness to add booster balls to the cord. These accessories are buoyant, keeping the rope above water and preventing it from submerging. This adds safety, especially when the vessel's height is insufficient for towing. Securing the tow cord to the boat is similar to the steps outlined in Step 3. You can connect the tow rope using your preferred knot.
