Carrying Your Two Kayaks: A Complete Guide

You’re ready for a paddling adventure, but how do you get two kayaks to the water? Transporting multiple kayaks on your car is totally doable. It just takes the right setup and a bit of know-how. We’ll guide you through the steps to get your boats safely to your favorite spot.

Choosing the Right Kayak Rack System

The foundation for carrying two kayaks is a solid roof rack system. Not all racks are created equal, especially when you’re doubling up. You’ll need a system that can handle the combined weight and provide stable mounting points for two boats.

Understanding Your Rack Options

There are a few main types of rack systems. Your car might already have factory-installed crossbars. These are a good starting point, but you’ll likely need to add attachments for kayaks.

• Crossbars: These are the horizontal bars that span across your car’s roof. They are essential for any rack system.
• Kayak Carriers: These are the accessories that attach to your crossbars and actually hold the kayaks.

Types of Kayak Carriers for Two Boats

When it comes to carrying two kayaks, the way they sit on your roof matters. You have a few popular options, and each has its pros and cons.

J-Cradles: The Space Savers

J-cradles are a very common choice for carrying one or two kayaks. They hold your kayak on its side, sort of like a hockey stick. This vertical orientation often allows you to fit two kayaks side-by-side on a single set of crossbars. Research has shown this is a popular choice for many paddlers (Paddling Magazine).

• Pros: Can fit two kayaks easily, often keeps kayaks low and stable, good for longer trips.
• Cons: Can be a bit trickier to load and unload, may require wider crossbars or more spacing.

Stackers: The Ultimate Space Saver

Stackers are upright posts that mount to your crossbars. You can load kayaks on top of each other, hence the name “stacker.” This is an excellent option if you have a narrower vehicle or want to maximize space. Many experts recommend stackers for transporting multiple boats efficiently.

• Pros: Can fit two, three, or even four kayaks in some configurations, saves a lot of roof space.
• Cons: Loading the second kayak can be challenging without assistance, requires a sturdy rack system.

Universal Carriers & Saddle Systems

These systems use padded saddles that conform to the shape of your kayak. You typically lay the kayaks flat or slightly angled. While great for protecting your hull, fitting two kayaks side-by-side on universal saddles can be tricky unless you have a very wide vehicle or extra-long crossbars. Many sources suggest these are best for one kayak or if you’re using a trailer for a second boat (BoatUS).

• Pros: Easy on your kayak’s hull, simple to load kayaks flat.
• Cons: Limited space for two kayaks side-by-side, can take up more roof width.

Setting Up Your Crossbars

Before you even think about loading kayaks, you need to ensure your crossbars are properly installed and spaced. This is where stability comes from.

Spacing is Key

The distance between your front and rear crossbars is critical. For carrying two kayaks, you generally want them spaced as far apart as your vehicle allows, often 30-36 inches. This creates a stable platform for both boats. Many kayak rack manufacturers provide specific spacing recommendations for their products.

Weight Capacity Check

Always, always, always check your vehicle’s and your rack system’s weight limits. Your car’s manual will state the maximum roof load. The rack system and any attachments will also have their own limits. You don’t want to overload your car, especially on a long drive.

Example Weight Considerations:

Item	Typical Weight
Kayak (each)	30-80 lbs
Rack System + Carriers	15-30 lbs
Straps & Tie-downs	negligible
Total (2 Kayaks)	75-190 lbs

As you can see, two kayaks can add up quickly! Always aim to be well within your car’s limits.

Loading Your Two Kayaks

This is where the muscles might come into play, or at least some clever technique. Loading two kayaks requires planning, especially if you’re doing it solo. Many paddlers find that a kayak loading assist system can be a real help.

Loading Side-by-Side (J-Cradles or Saddles)

If you’re using J-cradles or saddles, you’ll be loading them next to each other. Position the kayaks so they are parallel. You might need to lift one end of the kayak onto the car, then pivot the rest of the boat up. Having a second person makes this significantly easier. If you’re alone, consider using a roller system on the rear crossbar to help get the kayak started onto the rack.

Loading Stacked (Stackers)

Stackers offer a unique challenge. The bottom kayak goes on first, usually resting on the lower bars of the stacker. Then, you lift the second kayak on top. This often requires some strength and coordination. Some stacker systems have integrated steps or allow for easier loading of the bottom boat. Many resources suggest that for stacked kayaks, a loading assist roller is almost essential for solo transport.

Securing Your Kayaks: The Most Important Step

Once your kayaks are on the rack, you must secure them properly. This isn’t just about preventing them from falling off; it’s about keeping everyone on the road safe. Experts consistently emphasize the importance of proper tie-downs (NHTSA).

The Power of Straps

You’ll need at least two straps per kayak, often more. These are typically cam straps or ratcheting straps. Cam straps are often preferred for kayaks as they are less likely to over-tighten and damage the hull.

• Strap placement: Run one strap over the hull and attach it to each side of your rack system. Run a second strap similarly over the cockpit or a strong structural point.
• Tightness: Straps should be snug, not so tight that they deform the kayak’s hull. You want them tight enough so the kayak cannot shift side-to-side or front-to-back.

Bow and Stern Lines: Essential Safety

This is non-negotiable for safe transport. You need to attach lines from the bow (front) and stern (back) of each kayak to secure points on your vehicle’s frame. Many cars have specific tie-down loops underneath the front and rear bumpers. You can also use straps that loop around the frame, but avoid attaching to plastic parts.

• Why bow and stern lines? They prevent the kayaks from lifting or shifting forward or backward, especially during sudden stops or strong winds. Many safety guides consider these the most critical part of securing your load (U.S. DOT).
• How to attach: Run the line from the kayak’s grab loop or a secure point to your car’s frame. Make sure the line is taut.

A Pre-Drive Checklist for Peace of Mind

Before you hit the highway, do a final check. This quick inspection can save you a lot of trouble. What should you look for?

• Wiggle Test: Grab each kayak and try to shake it. It should feel completely solid, with no noticeable movement.
• Strap Tension: Double-check that all cam straps are tight and locked.
• Bow/Stern Lines: Ensure these are taut and securely attached.
• Clearance: Make sure your kayaks aren’t obstructing your view or hitting anything.
• Noise: Listen for any unusual flapping or rattling sounds as you start driving.

Taking your time with these steps ensures your kayaks arrive safely, and you can focus on the fun part – paddling!

Frequently Asked Questions

What’s the easiest way to load two kayaks by myself?

Loading two kayaks alone can be tough. Many people find kayak loading assist systems or rollers on the rear crossbar incredibly helpful. These accessories reduce the amount of direct lifting needed, allowing you to slide the kayak onto the rack more easily. Practice makes perfect, so try a few times in your driveway first.

Can I use my car’s factory roof rack to carry two kayaks?

You might be able to use your car’s factory crossbars as a starting point. However, these factory bars are often not wide enough or strong enough on their own for two kayaks. You will likely need to add specific kayak carriers (like J-cradles or stackers) that attach securely to your existing crossbars.

How do I know if my rack system is strong enough for two kayaks?

Always check the weight limits for both your vehicle’s roof and your specific rack system. The combined weight of two kayaks, plus the rack attachments, can be substantial. Your car’s owner’s manual will list its roof load capacity. The rack manufacturer will also provide load ratings for their products.

Are bow and stern lines really necessary if my kayaks are strapped down tight?

Yes, bow and stern lines are absolutely essential for safety, even with tight straps. They prevent the kayaks from lifting or shifting forward and backward, which can happen during braking or strong winds. These lines anchor your kayaks to your car’s frame, adding a critical layer of security.

Will carrying two kayaks affect my car’s gas mileage significantly?

Yes, carrying two kayaks on your roof will likely decrease your gas mileage. The added weight and increased aerodynamic drag create more resistance. You might notice a drop of 5-20% or more in your fuel efficiency, depending on your vehicle, speed, and the kayaks’ design. Planning your trips to account for this can be helpful.
