Mounting two kayaks on your roof rack is totally doable and a great way to transport your boats for weekend adventures. You’ll need the right setup, but with a few key accessories, you can securely strap down both kayaks for safe travel. It often involves using kayak saddles or stackers and ensuring you have enough rack space.
Successfully transporting multiple kayaks means considering the weight distribution and your vehicle’s capacity. Many roof rack systems are designed to handle this. You’ll want to research specific kayak carrier types that accommodate more than one boat to avoid damage to your vehicles or watercraft.
- Check your roof rack’s weight limit.
- Choose kayak carriers designed for multiple boats.
- Properly strap down each kayak using the bow and stern lines.
- Distribute the weight evenly across the roof.
Let’s walk through exactly how to get those two kayaks safely onto your roof rack, step by step.
Getting Two Kayaks Onto Your Roof Rack
Transporting two kayaks can seem like a puzzle. You might be wondering if your vehicle can handle it. The good news is that with the right accessories and a bit of know-how, you can safely bring both your kayaks along for the ride. We’ll guide you through the process, ensuring your boats are secure and your trip is stress-free.
Choosing the Right Kayak Carriers
Selecting the proper carriers is the first big step. Think of them as the specialized seats your kayaks will rest on. These aren’t just basic straps; they’re designed to hold your kayaks securely and prevent damage. Many systems are available, each with its own benefits.
Types of Kayak Carriers for Multiple Boats
When you’re looking to mount two kayaks, you have a few main options for carriers. Each type offers a different way to position your boats on the roof.
Kayak Saddles
Kayak saddles are padded rests that conform to the shape of your kayak. You typically mount a set of four saddles (two front, two rear) onto your crossbars. For two kayaks, you’ll need enough space on your crossbars for two sets of saddles. Some saddles are designed to be more forgiving for different hull shapes. We found that saddles offer excellent support for your kayaks during transit. They distribute the weight evenly across the hull.
Kayak Stackers
Kayak stackers are vertical posts that allow you to place kayaks on top of each other, usually side-by-side on a single crossbar. You’ll often use a single stacker that holds two boats. This is a great option if you have limited crossbar length or want to maximize space. Stackers usually come with straps to secure the kayaks to the posts and to each other. Research suggests stackers are a space-saving solution for transporting multiple watercraft. They can be particularly useful for narrower vehicles.
J-Cradles
While J-cradles are excellent for single kayaks, they can be challenging to fit two on a standard roof rack system. You would need very wide crossbars and careful placement. Most people find saddles or stackers a more practical choice for hauling two boats. We recommend sticking to saddles or stackers for easier loading and security.
Consider Your Roof Rack System
Not all roof racks are created equal. The type of crossbars you have will influence the carriers you can use. Most carriers are designed to fit round, square, or aero (wing-shaped) crossbars. Always check the compatibility between your carriers and your existing rack. Some systems might require specific adapters. It’s worth checking your roof rack manufacturer’s recommendations for kayak transport.
Essential Accessories for Secure Mounting
Beyond the carriers themselves, a few other items are absolutely essential for safely securing your kayaks. Think of these as your backup security team.
Straps
You’ll need strong, reliable cam straps. These are specifically designed for securing loads. Most carriers will come with some straps, but it’s wise to have extra. Look for straps that are at least 9 feet long. This ensures you have enough length to go around the kayak, the crossbar, and buckle securely. Always ensure the cam buckle is of good quality and easy to operate. We found that straps with protected buckles can prevent scratching your kayaks.
Bow and Stern Lines
These lines are critical for preventing your kayaks from lifting or shifting during travel, especially at highway speeds. They attach from the bow and stern of each kayak to points on your vehicle’s frame (like a tow hook or a dedicated under-hood strap). These lines stabilize the kayaks and take stress off the roof rack system. Many experts emphasize their importance for safety (NHTSA).
Tie-Down Point Anchors
You’ll need secure points on your vehicle to attach your bow and stern lines. Some cars have integrated tie-down points. Others might require you to purchase separate anchor straps that loop under the hood or trunk. Ensure these anchors are robust and properly installed. Never try to secure bow and stern lines to plastic bumpers; they can break.

Step-by-Step Loading and Securing Process
Now that you have your gear, let’s get those kayaks loaded. Patience is key here. Rushing can lead to mistakes. It’s often easier with two people, especially for heavier kayaks.
Positioning Your Kayaks
When placing two kayaks, consider how they fit best on your crossbars. Side-by-side is common. If using saddles, you’ll likely position them hull-down. If using stackers, one kayak will sit directly on top of the other. Try to place the kayaks so their weight is balanced evenly across your vehicle’s roof. If one kayak is significantly heavier, try to position it closer to the center of the vehicle.
Attaching with Cam Straps
Once the kayaks are in place, it’s time for the cam straps. Loop one strap over the kayak and under the crossbar. Then, loop it over the other side and through the cam buckle. Tighten the strap firmly. Repeat this for all your saddle sets or stacker points. Ensure the straps are snug, but avoid overtightening to the point of deforming the kayak hull. Double-check each strap to ensure it’s secure.
Connecting Bow and Stern Lines
Now, attach your bow and stern lines. Use one line for the bow of each kayak and one for the stern. Connect one end to the grab loop or handle on your kayak. Connect the other end to a secure anchor point on your vehicle. Make these lines taut. They should have a little give but not be loose. The goal is to prevent the kayaks from bouncing or lifting. We found that a simple figure-eight knot is effective for securing these lines.
Important Checks Before You Drive
Before you hit the road, a final check is crucial. This is your last chance to catch anything that might be loose or out of place.
- Give each kayak a firm push and pull. They should feel solid.
- Check all straps and knots one last time.
- Ensure the kayaks aren’t interfering with doors or windows.
- Confirm your bow and stern lines are securely attached.
- Take a look at your vehicle’s manual for weight limits.
It might seem like a lot, but these steps ensure your kayaks arrive safely at your destination. Remember, safe transport means a more enjoyable adventure for everyone involved!
Conclusion
You’ve now got the knowledge to safely transport two kayaks on your roof rack. We covered choosing the right carriers like saddles or stackers, and the essential accessories such as cam straps and bow/stern lines. Remember to always double-check your roof rack’s weight capacity and your vehicle’s setup. Taking the time for proper loading and securing means your kayaks will be ready for adventure. So, get out there and enjoy your next paddle!
Frequently Asked Questions
How do I know if my roof rack can support two kayaks?
Check your roof rack manufacturer’s specifications for its maximum weight capacity. You’ll need to consider the weight of both kayaks plus the carriers. If you’re unsure, it’s best to err on the side of caution or consult a professional.
Can I use just straps to mount my kayaks?
While straps are essential for securing, they aren’t enough on their own for two kayaks. You need dedicated kayak carriers like saddles or stackers to properly support and position the boats on your crossbars. Straps alone can damage your kayaks or rack.
What’s the difference between saddles and stackers for carrying two kayaks?
Kayak saddles cradle each kayak individually on padded rests, usually hull-down. Kayak stackers are vertical posts that allow you to place kayaks on top of each other, side-by-side. Stackers are a great space-saving option for narrower vehicles.
Are bow and stern lines really necessary when carrying two kayaks?
Yes, bow and stern lines are absolutely critical for safety. They prevent kayaks from lifting or shifting, especially at highway speeds. These lines stabilize the boats and take stress off your roof rack system.
How tight should I make the cam straps on my kayaks?
You want to make the cam straps snug and secure, but not so tight that you deform the kayak’s hull. Tighten until the kayak feels firmly attached and doesn’t move. Give each kayak a good shake to test for any looseness.
