Stand-up paddleboarding has become one of the UK’s fastest-growing outdoor activities, but transporting a paddleboard safely is something many owners underestimate. A SUP creates a huge surface area on the roof of a vehicle, and if it is not secured correctly, wind lift at motorway speeds can quickly become dangerous.
Understanding how to carry a paddleboard on a car properly is essential not only for protecting your board but also for keeping other road users safe. With the right roof bars, carriers, and loading techniques, transporting a paddleboard can be simple, secure, and stress-free.
If you are planning long-distance journeys to beaches, lakes, or rivers, these five tips will help ensure your paddleboard stays firmly in place even at higher speeds.
The Physics of Wind Lift
One of the most important things to understand about how to carry a paddleboard on a car is the effect wind has on large flat objects. Paddleboards act almost like wings at speed, particularly when travelling on exposed roads or motorways.
As air flows underneath the board, upward pressure can build, creating lift. If the board is not secured correctly, this lift can cause movement, vibration, or in extreme cases, complete detachment from the vehicle.
This risk becomes even greater when:
- Driving at motorway speeds
- Carrying larger touring SUPs
- Travelling in strong crosswinds
- Using poor-quality straps
- Mounting boards too high above the roof
A stable roof bar system is the foundation of safe paddleboard transport. Premium roof bars from Thule provide a rigid and vehicle-specific mounting point designed to minimise movement under load. Unlike generic systems, properly engineered bars help distribute weight evenly while reducing flex and vibration.
When learning how to carry a paddleboard on a car, stability matters just as much as strap tension. Even perfectly tightened straps cannot compensate for an unstable roof bar setup.
Tip 1: Position the Board Correctly
The safest way to carry a paddleboard is usually deck-down, with the fin facing upward. This creates a flatter contact area against the roof rack pads or carrier system and reduces wind resistance.
Position the board centrally on the roof bars with even overhang front and rear. Placing too much weight at one end can increase instability at higher speeds.
Choosing the Right Straps and Carriers
Another key part of understanding how to carry a paddleboard on a car is using the correct securing equipment. Cheap straps or basic rope setups can loosen during long journeys, especially in wet or windy conditions.
Tip 2: Use High-Quality Cam Buckle Straps
Cam buckle straps are widely considered the safest option for paddleboard transport. They provide secure tension without the risk of overtightening and damaging the board.
Avoid ratchet straps where possible, as excessive force can put unnecessary pressure on the paddleboard and potentially damage the construction.
High-quality straps should:
- Be weather resistant
- Include protective buckle covers
- Remain tight under vibration
- Be long enough for the board and roof setup
Tip 3: Use Dedicated SUP Carriers
Dedicated SUP carriers add another level of stability when learning how to carry a paddleboard on a car. These systems are designed specifically to cradle paddleboards securely while improving load distribution.
Dedicated carriers also help reduce side-to-side movement and provide extra grip during long journeys.
Premium carriers often include:
- Padded support surfaces
- Integrated strap management
- Aerodynamic shaping
- Lockable security systems
These features help improve both safety and convenience, especially for regular paddleboard users.
Safe Loading Techniques for Long Journeys
Long-distance journeys place continuous stress on both straps and roof systems, making proper loading techniques extremely important.
Tip 4: Twist the Straps to Reduce Vibration
One of the simplest but most effective tricks when learning how to carry a paddleboard on a car is twisting the straps slightly before tightening them.
Flat straps can vibrate in airflow, creating loud humming noises and additional movement. A slight twist breaks up the airflow and reduces vibration significantly.
Tip 5: Use Front and Rear Tie-Downs
For motorway driving or long-distance travel, front and rear tie-downs add an extra layer of security. These lines help stabilise the board and reduce forward or upward movement caused by wind pressure.
Bow and stern tie-downs are particularly useful when:
- Carrying large touring boards
- Driving in windy weather
- Travelling at sustained high speeds
- Using taller vehicles such as SUVs or vans
Even when using premium roof bars, additional tie-downs provide extra reassurance during longer trips.
It is also important to stop periodically on long journeys to check strap tension. Temperature changes, rain, and road vibration can all affect strap tightness over time.
Avoiding Common Paddleboard Transport Mistakes
Many problems with SUP transport come from simple mistakes, including:
- Using worn or damaged straps
- Over-tightening the board
- Ignoring roof load limits
- Mounting the board off-centre
- Using incompatible roof bars
- Forgetting to secure loose strap ends
Learning how to carry a paddleboard on a car safely starts with choosing the correct roof setup for your vehicle.
Not all roof bars are designed for high-surface-area loads such as paddleboards. Vehicle-specific roof bar systems provide better stability, improved aerodynamics, and safer load
distribution compared to generic alternatives.
The easiest way to find the correct setup is by using the Reg Lookup Tool on our website. Simply enter your registration number to identify compatible roof bars and SUP carriers designed specifically for your vehicle.
With the right roof rack system, quality straps, and safe loading techniques, transporting your paddleboard can be secure, quiet, and worry-free, allowing you to focus on getting out on the water.
