Kevel chock

Types of Kevel Chock

Kevel chock is a device used for mooring boats. It is a vital piece of equipment used to secure a vessel to a dock, ensuring stability and safety. Like any other equipment, kevel chocks come in different types. Here are some of them:

• 1. Wooden kevel chocks:

  Wooden chocks are made from softwood. They are affordable, easy to use, and float, which makes them easy to retrieve when dropped. However, they have limited durability and can be worn out by repeated use.

• 2. Rope kevel chocks:

  These are used for securing boats to docks or other vessels. The rope is tied to the dock or other vessel, and the boat is tied to the rope, providing a flexible and adjustable mooring arrangement.

• 3. Metal kevel chocks:

  These are usually made from steel or aluminum. They are strong and durable, making them ideal for heavy-duty use. They are also resistant to corrosion, especially if they are made of aluminum.

• 4. Plastic kevel chocks:

  These chocks are made from high-density polyethylene. They are lightweight, affordable, and resistant to corrosion and UV radiation. However, their durability and strength might be limited compared to metal chocks.

• 5. Captive kevel chock:

  A captive kevel chock is a type of kevel chock designed to keep the mooring lines on board a vessel. It is a closed or partially closed chock that prevents lines from slipping off the chock, reducing the risk of accidents and improving the safety of the crew. It is commonly used in situations where keeping the mooring lines on board is essential, such as in busy ports or with vessels operating with a small crew.

• 6. Fairlead chock:

  A fairlead chock is a type of chock designed to guide ropes or lines and reduce friction and wear. It is typically equipped with rollers or a fairlead horn that allows lines to pass through easily, minimizing the risk of tangling or snagging. Fairlead chocks are commonly used in applications where guiding lines is necessary, such as in towing operations or when handling sailboats.

Specifications and Maintenance of Kevel Chock

• Regular Inspection

  Conduct regular inspections to identify any signs of wear, damage, or deterioration. This includes checking for cracks, breaks, or deformities in the chock's structure.

• Cleaning

  Regularly clean the chocks to remove dirt, debris, and contaminants. This can be done using a mild detergent, water, and a soft brush. Proper cleaning prevents the buildup of substances that may affect grip or cause damage.

• Proper Storage

  When not in use, store chocks in a dry, clean area away from direct sunlight and extreme temperatures. Proper storage prevents premature aging or deterioration of the chock material.

• Replacement

  Follow the manufacturer's recommendations regarding the lifespan of chocks and when to replace them. Even if there are no visible signs of damage, chocks can wear out over time and lose their effectiveness.

• Training and Usage Guidelines

  Ensure that personnel using chocks are properly trained in their correct placement and use. Follow the manufacturer's guidelines for proper use and maintenance practices.

• Inspection of Accessories

  If the chocks have attached accessories (such as handles or connectors), inspect them regularly for wear or damage and replace them if necessary.

How to Choose Kevl Chock

Choosing the right kevel chock for specific needs requires careful consideration of several factors:

• Load Capacity: Chocks are designed with different load capacities to secure various sizes and weights of vessels. Select a chock that can support the weight of the vessel to ensure safety and prevent accidents.
• Material: Chocks are available in different materials, such as rubber, plastic, and metal. Each material has advantages depending on the environment and the vessel's type. For example, rubber chocks provide excellent grip and durability, making them suitable for various applications.
• Size and Shape: Chocks come in various sizes and shapes to accommodate different vessels and docking conditions. Consider the vessel's dimensions and the docking environment when selecting a suitable chock size and shape.
• Environmental Resistance: If the chock will be used in harsh environments, such as saltwater or extreme weather conditions, choose a chock that is resistant to corrosion and other environmental factors to ensure long-lasting performance.
• Visibility: Chocks are often painted bright colors to enhance their visibility and reduce the risk of accidents. Consider choosing a brightly colored chock to improve safety in busy docking areas.
• Compliance with Regulations: Ensure that the chosen chock complies with relevant industry standards and safety regulations. This is crucial for commercial vessels and must meet specific safety requirements.
• Ease of Handling: Consider the ease of chock placement and removal during docking operations. Chocks with handles or lightweight designs can improve efficiency and safety during docking and undocking procedures.

By considering these factors, vessel owners and operators can select the right kevel chock to enhance docking safety and efficiency, ensuring smooth and secure operations in various maritime environments.

How to DIY and Replace Kevel Chock

Replacing a kevel chock can be a straightforward process, and with the right tools and safety measures, even non-professionals can do it. Here is a step-by-step guide on how to replace a kevel chock:

Tools and Materials Needed:

• New kevel chock
• Wrench set or socket
• Hammer
• Pry bar
• Torque wrench
• Lifting equipment (such as a crane or hoist)
• Safety glasses
• Gloves

Step-by-Step Guide:

• 1. Put on safety gear: Before starting, ensure to wear safety glasses and gloves to protect from potential hazards.
• 2. Prepare the vessel: Ensure the vessel is stable, and the workload is not hazardous. Use lifting equipment to raise the vessel if needed.
• 3. Remove the old chock: Use a wrench or socket to remove any bolts or nuts that attach the old chock to the deck. A hammer and pry bar may be needed to dislodge the chock if it is corroded or seized in place.
• 4. Clean the area: Clean the area where the new chock will be installed. This ensures a proper fit and prevents corrosion.
• 5. Install the new chock: Place the new chock in the desired position and align it with the holes. Use bolts or nuts to secure it.
• 6. Tighten the bolts: Use a torque wrench to tighten the bolts or nuts to the manufacturer's specifications. This ensures that the chock is securely fastened without over-tightening, which can cause damage.
• 7. Test the chock: Once the new chock is installed, test it to ensure it functions correctly. Simulate a mooring situation to verify its performance.
• 8. Final inspection: Perform a final inspection to ensure everything is in place and functioning properly. Remove any tools or lifting equipment used during the replacement.

Q and A

Q1: What is the difference between a kevel chock and a regular chock?

A1: The kevel chock is not a different type of chock. It's a specific name given to a chock used in the marine industry, particularly for boats and ships. The kevel chock is used to guide ropes or cables and reduce wear and tear. In contrast, other chocks like wheel chocks are used to prevent vehicles from rolling?

Q2: Can a kevel chock be used on land-based vehicles?

A2: While the kevel chock is primarily used in marine applications, its purpose can be relevant in other contexts. Any chock can be used on land-based vehicles, provided they meet the required specifications and standards. However, finding a suitably sized and designed chock for land-based vehicle needs might be challenging?

Q3: Are kevel chocks customizable for specific vessels?

A3: Yes, kevel chocks can be customized to suit specific requirements for various vessels. Customized kevel chocks can be designed based on the size, type, and material of the vessel, and the ropes or cables used. This ensures optimal fit and functionality, enhancing safety and performance?

Q4: Are kevel chocks used for pleasure boats or only commercial vessels?

A4: Kevel chocks are not only used for commercial vessels but also for pleasure boats. However, the size and design may vary depending on the vessel type. For example, larger commercial vessels require bigger and more robust chocks than smaller chocks for private yachts or sailing boats?

Q5: How are kevel chocks maintained?

A5: Kevel chocks require regular inspection and maintenance like any other equipment. Users should check for signs of wear, corrosion, or damage and address them promptly to ensure optimal performance and safety. Depending on the material, chocks may also require cleaning and protection against environmental factors like saltwater and corrosion?
