This guide is for anyone looking to safely transport two kayaks on a roof rack, whether you're a beginner or experienced paddler. Properly securing your kayaks is essential for safety and protecting your gear. In this guide, we’ll walk you through the essential steps and tips on how to strap two kayaks to a roof rack, ensuring a safe and stress-free start to your next kayaking adventure.

Preparing the Kayaks and Roof Racks

Before you even lift your kayaks onto the roof, it’s crucial to get both your kayaks and your roof rack system ready for the journey ahead. Follow these foundational steps to ensure your setup is safe and efficient.

Check Roof Rack Attachment

Make sure your roof rack is firmly attached to your vehicle’s roof rails.
Confirm that the crossbars are spaced to support the full length and width of your kayaks.
If you’re transporting two kayaks or multiple boats, consider using a stacker or extended crossbars to give each boat enough room and support.
Stackers are recommended for transporting multiple kayaks as they allow for more efficient use of roof space. Using a stacker rack can help transport multiple kayaks more efficiently on a roof rack.

Use Foam Blocks or Cradles

Place foam blocks or cradles on the crossbars to protect your kayaks’ hulls and keep them from shifting during transport.
These not only cushion your boats but also help prevent sliding, especially at highway speeds or on bumpy back roads.

Remove Loose Gear

Remove any loose kayak gear or accessories that could come loose while driving.
Secure paddles, seats, and other essentials with cam straps or ratchet straps, making sure nothing can shift or fall off.

Check Weight Limits

Check your vehicle's manual for specific roof weight limits and recommendations. Many vehicles have a dynamic load limit for roof racks, which is often lower than the static load limit. The weight limit for roof racks is typically specified by the manufacturer and should not be exceeded to avoid damage to the vehicle.
Always check that the combined weight of your kayaks and gear doesn’t exceed the roof rack or crossbars’ weight limit.
For long-distance trips or when carrying multiple kayaks, a kayak trailer can be a good solution, offering extra stability and making loading and unloading much easier.

Once your kayaks and roof rack are prepared, you’re ready to load and secure your kayaks. Let’s move on to the step-by-step process for strapping down two kayaks.

How to Strap 2 Kayaks on Roof Rack: Step-by-Step Instructions

Most factory-installed roof racks or aftermarket roof racks are capable of supporting and carrying two kayaks at a time. However, attempting to strap two kayaks down to your roof rack for the first time may prove to be quite the challenge.

Kayaks can be carried on a variety of vehicles, including cars and trucks, and the method described here works for most boats.

There are many ways to secure one kayak during transport, however, whether you’re a seasoned paddler or new to the world of kayaking, you know that strapping down two kayaks can be much more of a task. We often get calls regarding this scenario. So we’ve decided to lay out the ground rules in this article, teaching you the steps for safely securing your two kayaks using straps. (Experts recommend 4 Cambuckle Tie-Down Straps for this)

Step 1: Place Your Tie-Down Straps

Take two straps and place them in the middle of your front crossbar, both straps should be resting down the center of your windshield.
Do the exact same with the rear crossbar, making sure both straps are now resting in the middle of your rear window.
Ensure your straps are not twisted and that they are easy to reach.

Step 2: Place Your First Kayak

Grab your kayak and hoist it to one side of your roof rack.
Try different positions and find a good way for this kayak to sit on your vehicle.
Keep this kayak as far towards one side as you can (driver’s or passenger’s side).
Using a flat roof rack or flat crossbars helps distribute weight evenly and makes loading easier.

Step 3: Strap Down Your First Kayak

Secure both the front and rear tie-downs over the first kayak.
Leave some wiggle room as you may need to make adjustments after your second kayak is placed.

Step 4: Place Your Second Kayak

Take your second kayak and lift it onto your roof rack.
Push it up against the first one.
If you have lots of room in-between both kayaks, you can choose to leave it to prevent the two rubbing up against each other.
If you have a small roof rack and find yourself tight on space, adjust your first kayak and make room for both kayaks to fit centered on your roof rack.

Step 5: Strap Down Your Second Kayak

Place the 2nd set of front and rear straps over your second kayak.
Secure and tighten these straps so that your second kayak is completely secured to your roof rack.
For extra security, use bow lines and stern lines to prevent the kayaks from wobbling or coming loose; a rope can be used if straps are not available.

Step 6: Tighten Down Your First Kayak

Check and make sure the first kayak is still sitting on your roof rack correctly.
Tighten your straps and make sure it’s secured.

Step 7: Recheck Your Tie-Down Straps for Tightness

Take a quick walk around your vehicle and confirm that your kayaks are strapped down correctly and tightly.
Wrap up any excess strap around your crossbars to prevent them blowing in the wind.
When tightening, make sure to pull the straps tight and check both sides of your car or truck to ensure everything is secure.
If the position of one kayak is off, you can loosen up both kayaks and reset them following the above steps.

When it comes to rack types, you can use J racks or transport your kayaks in an upright position as alternatives. J-style carriers are a popular option for transporting two kayaks on a roof rack. Some people also use a hitch-mounted rack or T-bar for additional support, especially when carrying multiple or heavier boats.

Always make sure you don't hit or exceed the rack's weight limit, and following manufacturer guidelines is fine for safe transport. Kayaks should be properly carried and secured to prevent them from shifting or falling off during transit.

Now that your kayaks are securely strapped, let's look at how to care for them during and after your journey.

Kayak Transport Checklist: Key Safety Points

Before you hit the road, review this checklist to ensure your kayaks are secure and your transport is safe:

Secure each kayak individually with its own set of straps.
Use two cinch straps per kayak for optimal security.
Use bow and stern lines for added stability, especially for longer trips or heavier kayaks.
Place kayaks hull-up or on their sides using J-cradles for best support.
Run a strap through a security loop or handle near the cockpit to prevent slipping.
Check crossbar length and spacing for adequate support; wider spacing generally provides better stability.
Consider the total weight of kayaks and gear; check your vehicle manual for roof rack weight limits.
Use aftermarket crossbars for higher capacity if needed.
Transport kayaks parallel and centered on your roof rack for maximum stability.
Always have a backup system in place (such as extra straps or ropes) and secure any extra rope or strap to prevent flapping in the wind.

Caring for Your Kayaks on the Road and Beyond

Ensuring the safety and longevity of your kayaks goes beyond the actual transport. Here are some essential tips to care for your kayaks during transit and beyond:

Regular Inspection:
Before and after each trip, inspect your kayaks for any signs of damage, wear, or potential issues. Look for cracks, scratches, or loose hardware that may have occurred during transport.
Cleaning and Maintenance:
After kayaking adventures, rinse your kayaks with fresh water to remove any saltwater or debris. Clean them using a mild soap and water solution to maintain their appearance and prevent deterioration.
UV Protection:
Prolonged exposure to sunlight can cause fading and damage to your kayak's hull. Store your kayaks in a shaded area or use UV-resistant kayak covers when not in use.
Storage:
When storing your kayaks, use padded kayak racks or storage systems that provide proper support and prevent warping. Avoid leaning them against hard surfaces for extended periods.
Secure Straps and Accessories:
Even when not in use, make sure your kayak straps and accessories are securely stowed to prevent any wind-induced vibrations or potential damage during storage.
Lubrication:
Periodically lubricate the moving parts of your kayak, such as hatches, rudder mechanisms, and footrests, to ensure they function smoothly.
Kayak Covers:
Consider investing in kayak covers to protect your kayaks from dust, dirt, and potential environmental hazards during storage.
Regular Maintenance:
Follow manufacturer recommendations for any specific maintenance procedures for your kayak model, including checking and tightening hardware, inspecting seals, and lubricating moving parts.

By incorporating these care and maintenance practices into your kayaking routine, you'll not only extend the life of your kayaks but also ensure that they remain in optimal condition for your next exciting paddling adventure.
