Can you convert a boat trailer into a kayak trailer? Absolutely. With careful planning, readily available materials, and some DIY know-how, repurposing your underutilized boat trailer offers a cost-effective and customizable solution for safely transporting your kayaks.
Why Convert Your Boat Trailer?
Converting a boat trailer to a kayak trailer presents several compelling advantages:
- Cost-Effectiveness: Purchasing a dedicated kayak trailer can be a significant investment. Repurposing an existing boat trailer is often far more budget-friendly.
- Customization: You have complete control over the design and configuration, tailoring it precisely to the number and type of kayaks you need to transport.
- Durability: Boat trailers are typically built to withstand heavier loads, resulting in a robust and long-lasting kayak hauling solution.
- Space Saving: If you already own a boat trailer that is not in continuous use, converting it eliminates the need for storing an additional trailer.
Assessing Your Boat Trailer
Before diving into the conversion process, a thorough assessment of your existing boat trailer is crucial. Consider the following:
- Trailer Capacity: Determine the trailer’s weight capacity. Ensure it’s adequate for the total weight of your kayaks and any additional gear. Overloading is dangerous and illegal. Check the trailer’s VIN plate for this information.
- Trailer Size: Measure the trailer’s length and width to ensure it can accommodate your kayaks. Overhang should be kept to a minimum and legally compliant with your local regulations.
- Trailer Condition: Inspect the trailer frame for any signs of rust, damage, or wear. Address any structural issues before proceeding with the conversion. Pay close attention to the axles, suspension, tires, and lights.
- Wiring and Lights: Verify that the trailer’s wiring and lights are functioning correctly. Repair or replace any damaged components. Proper lighting is essential for safe towing.
Planning Your Conversion
This is perhaps the most important stage. A well-conceived plan will save you time, money, and frustration.
- Kayak Carrying Capacity: Determine how many kayaks you need to transport simultaneously. This will dictate the size and configuration of the racks or bunks.
- Kayak Types: Consider the size and shape of your kayaks. Longer kayaks will require a longer trailer and more robust support. Different kayak hull shapes may require different bunk or rack designs.
- Bunk vs. Rack System: Decide whether you prefer to use bunks or racks to support your kayaks. Bunks provide a more even distribution of weight, while racks offer greater versatility for transporting other gear.
- Materials: Choose appropriate materials for building the kayak supports. Pressure-treated lumber, galvanized steel, or aluminum are common choices. Consider the weight of the materials themselves.
- Securing Kayaks: Plan how you will secure the kayaks to the trailer. Ratchet straps, cam straps, or specialized kayak tie-down systems are all viable options. Prioritize security and ease of use.
Implementing the Conversion: Step-by-Step
This section provides a general overview of the conversion process. Specific steps will vary depending on your chosen design and materials. Safety should always be your top priority. Wear appropriate personal protective equipment (PPE), such as safety glasses and gloves, throughout the process.
- Remove Existing Boat Hardware: Carefully remove any boat-specific hardware from the trailer, such as winches, rollers, and bunks. This will create a clean slate for your kayak supports.
- Construct or Purchase Kayak Supports: Build or purchase the kayak bunks or racks according to your plan. Ensure they are properly sized and shaped to support your kayaks. If using lumber, treat it to resist water damage. If using metal, ensure it is rust-resistant.
- Attach Supports to Trailer Frame: Securely attach the kayak supports to the trailer frame. Use bolts, U-bolts, or welding to create a strong and durable connection. Ensure the supports are evenly spaced and properly aligned. Consider using rubber pads or carpet to protect the kayaks from scratches.
- Install Lighting and Wiring (If Necessary): If any wiring or lighting needs to be adjusted or replaced, do so at this stage. Ensure all connections are secure and waterproof.
- Add Safety Features: Install any additional safety features, such as reflective tape, safety chains, and a spare tire mount.
- Test and Adjust: Load your kayaks onto the trailer and test the configuration. Make any necessary adjustments to ensure the kayaks are securely supported and properly balanced.
Considerations for Bunk vs. Rack Systems
Choosing between bunk and rack systems is a key decision.
Bunk Systems
- Pros: Better weight distribution, easier loading and unloading (depending on design), suitable for heavier kayaks.
- Cons: Can be less versatile for transporting other gear, may require more precise alignment.
Rack Systems
- Pros: More versatile for transporting other gear (bikes, camping equipment), adjustable to accommodate different kayak sizes.
- Cons: Can be more challenging to load and unload kayaks, potentially uneven weight distribution if not properly designed.
Securing Your Kayaks: Best Practices
Properly securing your kayaks is paramount for safe transport.
- Use Quality Straps: Invest in high-quality ratchet straps or cam straps specifically designed for securing cargo. Avoid using rope, as it can stretch and loosen over time.
- Securely Anchor Straps: Anchor the straps to strong points on the trailer frame. Avoid anchoring to weak or flimsy components.
- Distribute Tension Evenly: Ensure the tension is evenly distributed across all straps to prevent the kayaks from shifting during transport.
- Check Straps Regularly: Stop frequently during your trip to check the straps and tighten them as needed. Wind resistance and vibrations can cause them to loosen.
- Use Bow and Stern Lines (Recommended): Consider using bow and stern lines to further stabilize the kayaks, especially on longer trips or in windy conditions.
Frequently Asked Questions (FAQs)
Here are some commonly asked questions regarding converting a boat trailer into a kayak trailer.
1. What tools will I need for this conversion?
Typical tools include: wrenches, sockets, a drill, measuring tape, a level, a saw (for lumber or metal), and potentially a welder if you choose to weld components. Personal Protective Equipment (PPE) is essential.
2. Is it legal to convert a boat trailer to a kayak trailer?
Yes, generally. However, ensure your conversion meets all local and state regulations regarding trailer size, lighting, and safety features. Check your local DMV or transportation authority.
3. How much weight can my converted kayak trailer carry?
Refer to the Gross Vehicle Weight Rating (GVWR) listed on the trailer’s VIN plate. This indicates the maximum permissible weight, including the trailer itself and its cargo. Never exceed this limit.
4. What’s the best material for building the kayak supports?
Pressure-treated lumber is a common and affordable option. Galvanized steel or aluminum offer superior durability and rust resistance but are more expensive.
